Testing A Tesla Model 3’s Battery Degradation After 14 Months & 60,000 Kilometers

June 17th, 2020 by Johnna Crider

Bjørn Nyland has shared a video on YouTube about his Tesla Model 3 Performance degradation testing. He’s had his Model 3 for 14 months. This test involves a long drive on a single charge. Just as he gets started on his drive, the navigation shows that if he is to stay below 85 km per hour, he can reach his destination, a Supercharger.

After a quick restroom break at a random gas station, the battery’s charge was down to 80%. At three hours in, the battery is down to 49.8%. Nyland explained in the video that he was halfway toward his destination and that the vehicle spent 34kWh. He was also driving at 80 km/h.

One thing he didn’t plan for was the accident that slowed down traffic during his journey. He had to take a detour and the car was at 10% charge. The detour made the trip a little bit longer — so he was really pushing it. He made it to his Supercharger and the final results were 132 kWh spent, with his battery level at 3.2%.

How Much Degradation Was There?
According to the battery management system he is using, the Model 3 was supposed to get 69.3 kWh, but Nyland’s numbers show that he only got 68.8 kWh —0.7 kWh missing. Nyland explained that the missing kWh was heat loss and that the BMS doesn’t account for it.

Nyland says that the battery’s degradation was 6% from the time he got it. The battery on April 27, 2019, was 73 kWh — 68.8kWh/73 kWh equaled to 0.942, which translated to a 6% degradation. “In the end, what matters is how many kilowatt-hours you can get out of the battery,” Nyland said in the video.

The video also includes some beautiful scenes of Norway from Nyland’s point of view.

Tesla Now Focused On Volume Production Of Tesla Semi — Leaked Email From Elon Musk Confirmed

June 10th, 2020 by Johnna Crider

Donny Dolittle shared a screenshot of a leaked June 9 email from Elon Musk regarding the Tesla Semi, indicating that it is finally going into production. Elon has now confirmed on Twitter that he did indeed send the email.

The email goes as follows: “It’s time to go all out and bring the Tesla Semi to volume production. It’s been in limited production so far, which has allowed us to improve many aspects of the design. Production of the battery and powertrain would take place at Giga Nevada, with most of the other work probably occurring in other states. Jerome and I are very excited to work with you to bring this amazing product to market!”

For more on Tesla President Jerome Guillen and the start of the Tesla Semi program, seee:

Jerome — The Man, The Myth, The Tesla Super-Engineer — #CleanTechnica Interview
Our Interview With Tesla President Jerome Guillen, Part Deux

One key from this short, yet exciting email:

The production of the battery for the Tesla Semi will take place at the Sparks, NV, Gigafactory. So will the powertrain. Elon Musk once noted that the main reason that Tesla hasn’t ramped up the Semi’s production was lack of battery cells. Apparently, battery production has really ramped up, especially considering that Model Y production just began last quarter.

Whenever Battery Day does arrive, we will have a lot to look forward to. I’ve never been excited about batteries before — not until Tesla.

In Tesla’s Q1 2020 earnings report, Elon Musk said that Tesla will delay production and deliveries of the Semi until 2021. It’s been an intense three years since the unveiling of the Tesla Semi and Tesla is now doing pretty well in meeting its goals, but this volume production launch is surprising. Perhaps Tesla has made a battery production breakthrough.

VAYA Africa Launches VAYA Electric, Positions Itself For Growth Across Africa

May 29th, 2020 by Remeredzai Joseph Kuhudzai

We recently looked at how evCrowdRoute and GridCars are rolling out EV charging networks in South Africa. Now VAYA Africa, a Mauritius-registered Transportation as a Service (TaaS) company, has launched an electric vehicle service in South Africa’s northern neighbor, Zimbabwe.

This is part of the company’s rollout strategy across Africa. Starting with Zimbabwe makes a lot of sense. Zimbabwe has been experiencing petrol and diesel shortages for the past 3 years. Filling up an ICE vehicle’s tank can be quite a challenge in Zimbabwe, and it could involve waiting in a queue at a petrol station all day! This is downtime TaaS providers cannot afford. Drivers of ICE vehicles are more likely to suffer from range anxiety in Zimbabwe than owners of EVs who can charge at home or at the office from the grid when its available or from solar.

“We are excited to launch the ‘VAYA Electric’ vehicle today as we start our journey of deploying innovative ways of harnessing clean, renewable energy to provide safe and convenient transportation services to the public on the African continent,” said Mrs Dorothy Zimuto, the CEO of Vaya Mobility in Harare.

She said VAYA Africa planned to roll out the VAYA Electric vehicles in West and East Africa soon, saying the vehicles would include a range of multi-purpose vehicles. “Our e-vehicle fleet will include passenger vehicles, motorbikes, vans, buses and dump trucks, all utilizing our VAYA hail riding platform. We believe this dovetails well with our vision of driving inclusive technology growth across Africa,” Mrs Zimuto said.

The transition to electromobility is gaining momentum with over 7 million electric passenger vehicles now on the road worldwide, according to the Electric Vehicle Outlook 2020 from BloombergNEF. There are also now over 500,000 e-buses, almost 400,000 electric delivery vans/trucks, 184 million electric mopeds, scooters, and motorcycles on the road globally. It’s good to start seeing more developments in Africa in the EV space. In this transition, there are many infrastructural aspects that need to be assessed and addressed along with several milestones that would need to be met along the way. These issues span across several fields including the local grid networks, power uptime, operations, and maintenance, as well as having a human resource pool of technical experts. These would be critical in rolling out a large EV charging and EV service ecosystem across Africa.

This is where Vaya, and Ugesi Energy, also a subsidiary of Econet Global, can leverage on the experience of the Econet Group. The Group has rolled out large infrastructure networks and projects across Africa. For example, Liquid Telecom has built Africa’s largest independent fiber network, spanning over 70,000 km, and operates state-of-the-art data centers in Johannesburg, Cape Town, and Nairobi, with a combined potential 19,000 square meters of rack space and 78 MW of power.

Running a telecommunications network involves operating and maintaining a lot of power assets with thousands of sites. These can range from small 5 kW microgrids on Telco Towers to megawatt data and switching centers. The Econet Group already has a template and processes that it can roll out for its EV charging infrastructure, from site acquisition and leases with landlords and permitting from local councils and other related bodies. They already have teams of power engineers and technicians. The same technician that is probably on his way to a Telco Base station on one of the regular preventative or corrective maintenance runs can go and attend to an EV charger on their way. All these put them in a good position on the previously mentioned infrastructure milestones.

VAYA Electric will be part of VAYA Africa’s VAYA Premium service, a passenger service available on the VAYA Africa application that offers a wide variety of VAYA services – including logistics services.

Describing the customer fulfillment process, Mrs Zimuto said in order to enjoy a ride, one simply downloads the VAYA Africa App and looks for the Mobility Option. “They select the Electric Vehicle and this prompts them to choose the pickup and destination addresses, before requesting a ride,” she said.

She added that the App provided for convenient payment options, including mobile money payment, payment by VISA, MasterCard, or any other international debit or credit cards options.

“Electric vehicles have zero emissions and our aim is to ensure that all vehicles we have on the VAYA platform in the next ten years are electric vehicles,” said Mrs Zimuto, whose VAYA Africa service currently operates the largest hail riding service in Zimbabwe.

It’s good to see VAYA move to reduce emissions of vehicles on its platform. Econet Wireless has also moved to reduce emissions by installing solar PV at all its facilities and Telco Towers. Vaya has already installed charging stations at Econet Park in Harare, where the Nissan Leafs will also charge from solar. Econet Park has a 100 kW carport PV system installed on its campus. The move by VAYA Africa and Econet demonstrates the beauty of combining solar and EVs. The image below shows the generation and consumption profile on a typical weekend before installation of EV chargers.

The Solar Generation and Consumption profile on a typical weekend at Econet Park before installation of EV chargers. Image extracted from the SolarEdge Monitoring Platform.

From the profile, we can see that the building’s consumption is reduced on weekends as the load drops from a peak of over 100 kW on weekdays to about 40 kW on weekends. About 223 kWh can then be available for several VAYA EVs to soak up all that clean electricity in between their trips. 223 kWh is good enough for almost 9 full charges for 24 kWh Nissan Leafs and almost 7 full charges for the 30 kWh Nissan Leafs. Econet has also rolled out a first-of-its-kind and also the largest deployment of AC-coupled Li-ion batteries in the telecoms sector, deploying Tesla’s Powerwall 2s on its network, which we covered here .

Mrs Zimuto says electric vehicles will provide cost savings of up to 40% on the major running costs of fuel and regular maintenance, in comparison to vehicles that run on fossil fuels. They stand to save even more from increased PV contribution on weekends in places where excess solar generation is available.

“The benefits of the use of e-vehicles will be less frequent services and fewer scheduled vehicle maintenance check-ins than ordinary combustion engines. They will require minimal scheduled maintenance for their electrical systems, such as the battery and electrical motors. Other parts such as brakes also last longer because of their regenerative braking systems, where the battery is charged when braking,” Mrs Zimuto said.

Mrs Zimuto said e-vehicles would be charged on solar or on grid-tied electric charging stations across the country.

“Our electric vehicles will be charged on charging stations deployed across the country, built by Ugesi Energy, a subsidiary of Econet Global, to offer e-vehicle owners charging options just about anywhere around the country,” Mrs Zimuto said.

She added that VAYA Africa had provided for financing for the purchase of the VAYA Electric, which is great as it will lower the barriers for adoption and more driver partners on its platform can switch to electric.

“VAYA Africa has positioned itself as an enabler in the hail riding value chain. So, we will import the electric vehicles of various brands and at the same time facilitate loans to qualifying clients and VAYA partners through Steward Bank specifically for the purchase of the e-vehicles,” Mrs Zimuto said.

Did Audi Copy Tesla’s Website For Its FAQs Page? 👀

Twitter

Facebook

April 23rd, 2020 by Johnna Crider

Did Audi copy Tesla’s website to create its EV FAQs page? It sure looks that way. Twitter user CillDar shared that Andrew O’Connor saw something very familiar on Audi’s Ireland EV website. It seems that Audi was using text for its FAQs from Tesla’s Ireland website. He provided screenshots of both websites in the tweet below and highlighted the quote “Every New Model 3, Model S, and Model X is compatible with CCS charging.”

The side-by-side screenshots share a compelling story and I wanted to see if it were true so I clicked on Audi’s website from the tweet. However, when I got to the site, I didn’t see anything about Tesla. One would normally give up, but then I remembered the Wayback Machine. I learned of this little tool thanks to Wade Anderson, who helped me recover my open letter to Elon Musk that I wrote back in 2018. You see, my ex hacked my website and took it down. I had to start all over and I thought all my work was gone forever. Thank you, Wade, for not only saving the open letter that Elon shared, but all of my work. This tool is like a time machine for websites even if the domain no longer exists.

I wanted to see if what I suspected had happened. I suspected that whoever was working on Audi’s website was copying and pasting from Tesla’s website. If this were true, the archival site would show it. And it did, as you can see in the screenshot below.

It’s hard to tell in the image, but the link goes to Audi’s Ireland website. The archival site also noted that there have been two recent updates to this particular webpage. The archival site shows that the page was saved at 17:07:25 and at 17:07:48, which must be in the timezone wherever the site is hosted (probably Ireland).

It’s clear to see that whoever was designing the site was using Tesla’s as an example and wanted the Audi site to look as similar to Tesla’s as possible while being branded with the Audi logo and name.

I can understand Audi wanting to copy Tesla’s website. After all, Tesla is the leader in the EV industry, and the company knows its stuff. Nonetheless, seeing a well-known luxury car company use the example of a so-called newcomer to the industry that is “destined to fail and go bankrupt because of fraud” is really a compliment to Tesla. Notice I put that false description of Tesla in quotes due to it being a senseless mantra chanted by critics because it’s all they have left of an old pipe dream of failure.

This is not the most monumental, important story of the decade, but it is odd and interesting.

Full Self Driving (FSD) “Pay As You Go” Feature Included In Tesla Source Code

Twitter
LinkedIn
Facebook

April 29th, 2020 by Steve Hanley

FSD, or Full Self Driving, is a feature available on all new Teslas for $7,000 — if purchased up front. It costs more if is added later. Elon Musk says the price will rise substantially in the future. That’s because as each new ability is added, Tesla cars become more valuable compared to the auto industry pack, and when the system is fully activated, owners will be able to send their cars out as driverless taxis as part of the Tesla Network and generate scads of income from doing so.

[Personally, I would rather drink iodine than loan my brand new Tesla out to the great unwashed for them to use and abuse as they see fit, but lots of people think this is the greatest idea since sliced bread. There’s a good chance I am just stuck in the past and wouldn’t recognize a good idea if it bit me. Now back to your usual programming, already in progress.]

According to Tesla aficionado “green”/@greentheonly, Tesla also now has a plan to allow owners to access FSD on a “pay as you go” basis. How does he know? Tesla has already baked it into the latest source code updates.

There’s more we don’t know about this plan than we do know. One could think of it as a variation of the “lease or buy?” conundrum. Some people dislike leasing. They prefer to decide when to trade their car and they believe their precious vehicle will somehow be worth a ton at trade-in time, despite a wealth of evidence to the contrary. Others like the idea of getting a new car every 2 or 3 years. They know leasing costs more than buying but the advantages offset the difference. It’s one of those “you pays your money and you takes your choice” sort of things. It’s why they make chocolate and vanilla ice cream.

There is speculation that people could sign up for FSD when they need it — like before taking that family vacation to the coast — then deactivate it when they get home. No one knows if that is what Elon has in mind, though. All we can say at the moment is that, based on green’s tweet, the pay-as-you-go option is now included in Tesla software. Details on how the program works will have to come from Tesla when the company feels the time is right.

Tesla Overhauls The Body Shop For Model Y In Push For Full Body Casting
In their latest podcast, the Third Row Tesla crew talked with Elon Musk and Sandy Munro about some of the innovations Tesla brought to bear in optimizing the design of the Tesla Model 3. The new episode was released to Third Row Tesla’s Patreon supporters this morning and will be released on all your favorite media channels shortly: Website | Twitter | YouTube | Stitcher | Spotify.

The Tesla Model 3’s body was criticized by Sandy Munro in his early teardowns for an excessive amount of glued parts, unnecessary complexity, and potential failure points. “As Sandy accurately pointed out, the rear of the Model 3 looks like a patchwork quilt,” Musk said. “It’s not great.” Tesla improved upon this in the Model Y and has plans to do far more than it is already doing with a new unibody casting that came into existence as a result of looking at Hot Wheels versions of the Tesla Model S. When looking at the small toy cars, Musk wondered if the same single casting concept could be applied to their full-scale vehicles.

Today, the Tesla Model Y utilizes castings to bring together many of the small stampings, extrusions, and whatnot that comprised the rear of the vehicle into a handful of larger cast parts. “The current version of the Model Y has basically two big high-pressure die-cast aluminum castings that are joined.” That is a clear improvement over the Tesla Model 3, but Tesla wants to do more. “Later this year, we will transition a single piece casting that also integrates the two rear crash rails,” Musk said. Upon hearing this, Sandy Munro simply said, “Whoa!”

Consolidating the design of the body of the vehicle from a ton of parts built with dozens of disparate processes cuts down the amount of inventory, spare parts, raw materials, assembly processes, potential failure points, and more. Said another way, it’s cheaper, faster, and more efficient. “The current castings, because you have to interface with so many things, you have to CNC machine the interfaces and join all these things,” Musk said. “It’s quite difficult.”

Consolidating all the various welding, gluing, bolting, and riveting tasks from the Tesla Model 3 body shop into a single casting also translates to a smaller manufacturing footprint. “The manufacturing cost is much less and we see a 30% reduction in the size of the body shop, which is huge,” Musk said. That’s massive. Having walked through the Tesla body shop for the Model 3 last year, I can say that while it was extremely impressive to see so much automation being leveraged to build the body of the vehicles, the prospect of eliminating all those individual processes for a single casting that requires minimal processing after the fact is exciting.

The new rear assembly in the Model Y represents a drastic improvement over the Model 3, and Tesla is already hard at work on the next generation. “The single piece casting has no CNC machining,” Musk said on the Third Row Podcast. “It doesn’t even have datums. That’s profound, really. It took us a lot of iterations to get there. It sounds obvious.”

To bring the vision of massive cast body components to reality, Tesla bought not one, but two of the world’s largest casting machines. “It’s the size of a small house,” Musk said. “We should be starting to set up the one from Italy next month.”

Musk said that it was likely the tech would make its way into the Model 3 as well. “It’s probably something we would do, but maybe in like 2 years.” He commented that the design of the Model 3 body was a pain in the ass, but it worked. “We have to deal with the pain in the asses that don’t work. Those are the higher priorities,” he said.

Tesla continues to hire and inspire some of the best engineering minds of our day, but capacity continues to be a limiting factor for them. “There’s a lot of fish to fry here,” Musk said. From the outside looking in, the culture of continuous innovation and improvement is inspiring, but the frayed edges are maddening just the same. It’s a delicate dance that’s churning out some of the most exciting innovations in software, hardware, electronics, computing, chemistry, and mechanical engineering the world has ever seen. What an exciting time to be alive! The future is now, peeps.

Automotive Expert Sandy Munro On The Tesla Model Y: “Lots Of Room In There”

Twitter
LinkedIn
Facebook

April 1st, 2020 by Kurt Lowder

We have covered expert Sandy Munro and his company Munro & Associates multiple times on CleanTechnica over the years. When the Tesla Model 3 first came out, Munro led the charge to call Tesla out for out of spec panel gaps. For a short period, the corporate media preceded to interview and quote him often. Then, for the last two years, Munro changed his tone as Tesla improved its quality systems and has consistently praised Tesla. Accordingly, the mainstream media has hardly mentioned Munro.

CleanTechnica and a few others have been doing the reporting other outlets should have done. Mr. Munro should have weekly appearances on CNBC, Fox, CNN, and others. However, because he gushes about Tesla, the media now largely ignores him. Of course, it’s in the media’s massive financial interest to not praise Tesla too much. Tesla does not advertise, while GM spends billions a year on advertisements with mainstream media networks.

In an earlier piece, we discussed why Munro stated Tesla had a 10-year lead over its competitors. The truth is, from the talks that Munro has given, there are hundreds of articles even CleanTechnica hasn’t been able to cover. I have been meaning to cover his comments on the Cybertruck. In a recent interview, Munro marveled at how inexpensive the capital costs of the Tesla Cybertruck factory would be, primarily because no paint shop is required, but also because cutting and bending the cold-rolled steel is simple and inexpensive.

Munro is making decent money off of his Tesla reports. He is particularly in demand in China, as everyone is rushing to learn from Tesla’s innovation. However, the money seems to be only a little part of his motivation. Munro has no shortage of other clients. He even has clients in the defense industry. You have to understand that Munro is a workaholic engineer who absolutely loves what he does. He is the type that will never retire. From his videos, interviews, and even his reports, it’s clear that he lives and breathes engineering, manufacturing, and business. He has traveled the world to give detailed talks and presentations exclusively on Tesla. Many employees of Munro and Associates have enthusiastically bought Tesla vehicles as a result of their research.

After much anticipation, Munro recently took possession of a red Tesla Model Y. The video below is just his initial reaction and is only a few minutes long.

Munro and Associates will do a complete teardown of this Model Y, and the details will undoubtedly be doled out over the coming months. So, stay tuned. In the meantime, here are a few key quotes from what they have shared so far:

“This is like a Bentley trunk.”

“Lots of room in there.”

“Everything appears to be really, really nice.”

Munro did notice a few small gaps in this early edition Model Y, but having experienced Tesla’s rapid learning curve with the Model 3, he fully anticipates they will be corrected over time. He noted he correctly predicted this with the Model 3, which has seen dramatic improvement over the last two years to its near-perfect quality today.

Let’s focus on the quote, “there is lots of room in here.” In a previous article on the Tesla Model Y, we compared the cargo capacity of the Model Y to other vehicles. The Model Y, at more than 66 cubic feet of cargo space, dominated other EV crossovers in this key metric. Even compared to the gasoline-powered Toyota RAV4, the Tesla Model Y competed well, with only a few less cubic feet of cargo space. To get precise numbers, check out that earlier coverage of the Model Y.

Tesla Suspending Production At Fremont & Buffalo Factories, Initiates “Touchless Deliveries”

There has been much backing and forthing at Tesla about whether it should keep its US manufacturing facilities open during the coronavirus pandemic. According to a press release from Tesla, the decision has now been taken to temporarily suspend production at its automobile factory in Fremont, California and its solar factory in Buffalo, New York, as of Monday. The last cars in Fremont will come off the assembly line Monday night. Tesla’s Gigafactory in Nevada will remain in full operation.

Both states have been hit hard by the virus and California’s governor announced on Thursday he is ordering all 40 million inhabitants of the state to stay home. That action by the governor may have been the final piece that convinced Tesla to cease operations, after several days of uncertainty during which the company and local authorities wrestled over whether it would shut down or stay open.

Tesla said in a statement, “In the past few days, we have met with local, state and federal officials. We have followed and are continuing to follow all legal directions and safety guidelines with respect to the operations of our facilities, and have honored the federal government’s direction to continue operating. Despite taking all known health precautions, continued operations in certain locations has caused challenges for our employees, their families and our suppliers.” The company says it will continue to operate some basic operations such as its Supercharger network and service centers.

It is still considered an open question whether automobile production is considered an essential service on the federal level. We will update you have something notable changes with Tesla’s production plans. Tesla’s factory in Shanghai, China, is producing cars at this time, with its full ecosystem of suppliers back in operation following China’s earlier shutdowns.

Touchless Delivery
“In many locations, we are in the process of implementing ‘touchless deliveries’ so customers can continue to take delivery of their vehicle in a seamless and safe way,” the company statement said. How does that work? People picking up their new Tesla can now open the doors with their Tesla app, sign the delivery paperwork left for them inside the vehicle, drop it off at the delivery location, and drive away without ever coming in contact with another person.

Tesla is also still doing home deliveries in some cases. The following is a photo from a friend of CleanTechnica. He bought a Tesla Model 3 after test driving his son’s VW e-Golf, reading this article about 70 reasons Tesla Model 3 owners love their cars, going on a test drive, and ordering that night. He had it delivered to his home yesterday. We have an article on that coming soon.

Dazed & Confused In Fremont
Tesla employees are understandably confused. A few who spoke with BuzzFeed indicated they received an internal email saying they would be paid through Monday and would be provided with “paid leave during suspended operations.” Asked what that means, one worker admitted “none of us are really sure,” but that “some money is better than none.” That person, who asked to remain anonymous, told BuzzFeed he and his colleagues will keep showing up for work until the facility is closed.

As of this moment, no one knows how long the production shutdown in Fremont and Buffalo will last. Ford, General Motors, Fiat Chrysler Automobiles, Honda, Toyota, and Nissan have all said they will close their factories in the United States. Hyundai has already shuttered its Alabama factory after a worker tested positive for the virus, according to USA Today.

Rumor: Tesla Close To Deal With CATL To Use Cobalt-Free Batteries For Chinese-Made Cars

February 18th, 2020 by Steve Hanley

A report by Reuters, based on information supplied by unnamed sources, claims Tesla and Contemporary Amperex Technology Company (CATL)* are in the “advanced stages of talks” that may lead to Tesla using cobalt-free battery cells developed by the Chinese battery company. Cobalt is expensive — around $33,500 a ton — and much of it is sourced from operations that may exploit child labor. Tesla already chooses to not get cobalt from the most notorious sources, and Elon Musk has indicated he would like to drastically reduce the amount of cobalt used in Tesla batteries. In fact, the company uses far less of it today than it did a few years ago.

Those sources tell Reuters the two companies have been talking for more than a year and the talks could result in an agreement soon. Tesla and CATL both declined to comment on the story. In addition to avoiding the toxicity and environmental concerns associated with using cobalt, the latest lithium-iron-phosphate batteries from CATL are said to be cheaper than nickel-cobalt-aluminum (NCA) or nickel-manganese-cobalt (NMC) batteries by a “double digit percent,” according to the sources.

To boost the density and safety of its LFP batteries, CATL has been working on cell-to-pack technology, the sources told Reuters. They also indicated Tesla has no plans to stop using its NCA battery technology for its automobiles.

LFP batteries are typically less energy dense than NMC batteries, which means the company would have to use more of them to get the same range in its vehicles — unless there has been a big advancement in that territory. That also means they would take up more space (if range was kept the same). Where would Tesla find room in its cars for larger, heavier battery packs?

We know that Tesla is at the cutting edge in battery technology and knows far more than it is sharing publicly. Elon has indicated the company is constantly talking to everyone involved in battery research at a significant level anywhere in the world. Is this one of those cases that actually warrants a change in commercial products?

Lastly, is Maxwell Technologies, the battery and supercapitor startup Tesla bought last year, involved somehow? CleanTechnica contributors Chanan Bos and Max Holland will be along shortly to give you their take on this story. See: “Tesla Shanghai Model 3 May Go Cobalt-Free Using CATL’s LFP Cells — Diving Deeper.”

CATL-Built Tesla Model 3 Battery Pack Will Use Prismatic Cells

February 19th, 2020 by Chanan Bos

The battery news keep getting crazier each day. Exactly one week ago, we learned that Tesla might be assembling a battery cell production line in Fremont, then a few days ago that they are buying some battery startups in Denver and even Elon seems to have visited. Then, yesterday, we learned that Tesla in China might use lithium-iron-phosphate (LFP) batteries from CATL* in the Model 3 SR+, and that it’s all made possible by putting cells straight into the battery pack without modules. What we learned in today’s revelation is that those LFP batteries will be prismatic, and the pack might be built — or is at least designed by — CATL utilizing its cell-in-pack technology, something that Tesla is also working on but has thus far not yet implemented.

Only with LFP batteries
To repeat: Tesla in China will have a Model 3 battery pack that uses prismatic batteries instead of cylindrical ones and also has no modules. When I heard this news, there was only one thing that felt at least somewhat certain, that this is only possible with LFP cells. Most EVs lose their battery capacity after a few years, but Tesla’s hardly lose any capacity. By having so many cylindrical cells working together, each is only taxed slightly during discharge. Also, the batteries have little volume and plenty of surface area for some really good cooling.

In this strange circumstance, Tesla can maintain its quality, reduce the price, and use LFP prismatic cells. While each cell is taxed more, LFP batteries last longer, so that makes up the difference. The main disadvantage LFP batteries have is lower energy density. However, with this rare cell-to-pack technology, we can make up the difference to create the 50 kWh pack that the Model 3 SR+ needs.

Getting a picture of what this will look like

Quickly drawn render of prismatic cells on a Model 3’s battery pack

My first research effort was to take a look at the Model 3 battery pack as well as its insides, and then try to calculate what kind of cells will be used as well as how many and in what way they will be placed. Here are the approximate external dimensions of the Model 3’s battery pack: 216.63 cm by 147.32 cm by ~10.5 cm (L x W x H). Inside are 4 modules, each 9 cm high, 29.2 cm wide, and 185.4 cm long for the longer modules.

Here is what we can be somewhat certain of: even without modules, the height of each prismatic cell cannot be more than 90mm, and it is somewhere in that range. Almost all EV prismatic batteries are approximately 48mm thick, in which case we would could fit something like 38 rows of batteries in there. As for how many columns there will be, that could be something like 5 or 6.

Conclusion
Today’s news will take some time to process. Calculations need to be made and long showers need to be taken before we get any big new revelations about this. If there is one important takeaway from today’s news, it seems to be that the collaboration between CATL and Tesla is more serious than previously thought. It really does appear that CATL did a lot of legwork to design this unique new pack for Tesla without significantly altering the Model 3’s battery pack dimensions.

Either Tesla is going out of its way to make the Chinese authorities happy, or this arrangement really benefits Tesla and CATL, enough to design a whole new battery pack and risk exposing CATL’s cell-to-pack technology to the competition. When it comes to using prismatic cells, there are two concerns: how well these cells can be cooled and what kind of acceleration we can expect with this battery pack. One question that we saw a lot of people ask is, does this technology have a future if energy density can be significantly increased with Maxwell’s dry electrode technology? Who knows?
