French company makes EV conversions easy for old clunkers

Off-the-shelf EV conversions aren't just for classic cars like Prince Harry's Jaguar anymore.

French startup Transition One plans to make it easy to convert a wide variety of average old cars in the country to electric power by building a standard conversion kit. The company says the kit will fit several top-selling models in Europe, including the Renault Twingo II, Fiat 500, Citroën C1, Peugeot 107, Toyota Aygo, and VW Polo.

The kit will sell for about $9,400 (8,500 Euros), and buyers can receive a 3,500 Euro tax credit in France, bringing the equivalent cost down to about $5,500. The company plans to complete each conversion in about four hours, once production is up and running.

The company has started by building a prototype electric car from a 2009 Renault Twingo, a small hatchback about the size of a Toyota Yaris. It uses Tesla battery modules in three packs under the hood, along with the motor and power electronics, and two more battery packs where the gas tank once sat.

The packs weigh 265 pounds, giving it about 18 kilowatt-hours of energy, which the company says will deliver about 112 miles of range in the Twingo.

In an interview with Bloomberg, company founder Aymeric Libeau said, “I’m selling to people who can’t afford a brand new 20,000 Euro [$22,200] electric car.”

The plan might be compared to that of Montreal's Ecotuned—aiming to convert old Ford F-150s with dying gas powertrains to electric power for fleets. The types of large, body-on-frame trucks that Ecotuned converts are as plentiful in North America as the small cars that Transition One plans to convert are in Europe. Other conversion companies—and some automakers—have begun focused conversion efforts on certain classics, such as the Jaguar E-Type, Porsche 911, and the original Mini Cooper.

Libeau still needs to get his conversions approved by European regulators, which he says he expects to receive by the end of the year. Transition One is also seeking financing to buy a factory to produce up to 400 of the conversions a year, and plans to open orders in September to test the market demand.

Fully Charged Tests Porsche Taycan’s Performance

August 9th, 2019 by Dr. Maximilian Holland

Fully Charged’s Jonny Smith was given a unique opportunity to test the Porsche Taycan’s performance consistency, and was able to confirm its ability to handle repeated acceleration runs without running into thermal limits. The Taycan looks to be similar to the Tesla Model 3 Performance in this respect, but will come in at around twice the price of the Tesla. The Taycan is competing in a different segment, and will certainly appeal to Porsche enthusiasts and other well heeled consumers looking to make the switch to the technology of the future.

Fully Charged’s test drive was curated by Porsche and designed to highlight the Taycan’s relative strengths. Jonny Smith was clear enough: “My job here today is to prove Porsche’s repeatability of high performance.” In other words, to see whether the vehicle could accelerate repeatedly without hitting thermal limits.

Porsche has noted that whilst even the top-of-the-line Taycan (444 kW, 600 ps) will not match the outright acceleration of the Tesla Model S Performance for 0–62 mph times, instead, its engineering focus is on battery and motor cooling that will allow comparatively strong acceleration at speeds over 100 mph (161 km/h), and thus meet expected Autobahn performance, crucial for the home market.

They emphasize repeated acceleration runs, not that this has any practical use. It doesn’t. Instead, it correlates with sustained high-speed driving and Autobahn use patterns that are unnecessary outside of Germany but are symbolically crucial in the home market. This also allows Porsche to troll Tesla, since the Tesla vehicles are — perfectly sensibly — not primarily tuned for Autobahn performance, but instead offer other performance priorities that have broader global appeal. Trolling the clear market leader — Tesla — is a well established marketing practice when trying to establish a new product, and therefore Porsche actually gives kudos and acknowledgement to Tesla’s achievements in the EV space.

Porsche claims that the most powerful Taycan variant — featured in the video — will achieve 0–62 mph (0–100 km/h) acceleration in “under 3.5 seconds” and 0–124 mph (0–200 km/h) in “under 10 seconds.” What’s very encouraging is that this suggests that the Taycan will actually have better acceleration times to 124 mph (200 km/h) than its top-of-the-range, and much more expensive ($188,000), Panamera Sport Turismo Turbo S E-Hybrid sibling. This is a strong indication that Porsche is serious about its EV strategy, and not just playing politics, unlike some of the other German luxury brands.

The price for the high-end Taycan version featured in the video was unconfirmed, but is rumoured to be over $130,000 (before sales tax) in the US, around £120,000 in the UK (including taxes), and perhaps €130,000 in Germany (including taxes). Expensive, but much less than the top-end Panamera. The version tested will apparently be badged as the “turbo” variant. Yes, Porsche appears to be keeping its traditional ICE-era labels for the Taycan variants.

Screeenshot from Fully Charged’s video — Fully Charged/YouTube

The least expensive Taycan variant, that will likely appear later on, is rumoured to cost around $90,000 before options. That’s similar to the Tesla Model S Performance (see more below). It is also rumoured to have power significantly lower than the “turbo” variant featured in the video. The base Taycan may perhaps have 322 ps or 376 ps, rear drive only, and a smaller 80 kWh battery, compared to the 90 or 95 kWh pack, and AWD of the “turbo.”

By way of comparison, since Porsche obviously wants to “go there,” the Tesla Model S Performance costs $92,600 before taxes in the US (€102,700 in Germany, including tax) and will do 0–100 km/h in 2.6 seconds. That’s of course a quantum leap faster than the Taycan. Tesla makes no claims for the 0–200 km/h time, but independent testing has recorded 0–201 km/h (0–125 mph) in 10.5 seconds. This suggests the Tesla would likely have better acceleration than the Taycan at all speeds up to ~110 mph (177 km/h), and less acceleration thereafter.

The internal space of the Taycan is actually a closer match to the Tesla Model 3 than the larger Model S. The Model 3 Performance costs €55,400 in Germany ($55,000 in the US) and completes 0–100 km/h in 3.4 seconds (similar to the Taycan Turbo). The higher 0–200 km/h acceleration in the Model 3 requires around 14 seconds, which is a good bit down on the Taycan’s 10 seconds.

It’s tempting to compare the Taycan with the Teslas in this way, and Porsche has certainly set up the Taycan, and this testing day, to emphasize its comparative strengths relative to Tesla’s vehicles. However, I’d argue that the Taycan will be a much lower volume vehicle, significantly more expensive, and is actually going to be competing with and pulling buyers from fossil-burning alternatives, rather than competing with Tesla per se.

For those who might wish to compare the Taycan’s performance specs with the Teslas’, a key question is, what acceleration range is more relevant to most prospective owners globally? Would most buyers around the world prefer better performance in the range of 0–60 mph, and 0–100 mph? Or would most people prefer relatively strong acceleration at speeds above 100 mph (161 km/h)?

Design Parameters Only Relevant for the German Market?
The answer to the above question should be clear for most people. With few exceptions, only in Germany are speeds above 140 km/h (87 mph) legally allowed on public roads. Although a few drivers in other places will sometimes drive somewhat over their national speed limits, most outside Germany will almost never realistically drive much above 100 mph (161 km/h). Having high acceleration at speeds above 100 mph is therefore not something that gives owners much practical benefit, anywhere outside of Germany.

Screenshot from Fully Charged’s video — Fully Charged/YouTube

The exception is for the small percentage of folks who might occasionally want to push their car around a track. Even here, though, most of the tracks that keen amateurs drive don’t see speeds much above 100 mph (161 km/h) sustained for more than a very few seconds. Rates of acceleration at speeds above 100 mph therefore don’t have much influence on lap times. It’s typically more relevant to have good rates of acceleration from slow corner speeds of 40 or 50 mph, back up towards 60, 80, or 100 mph (161 km/h).

The Laguna Seca circuit in California, with a length of 3.6 km, only has one straightaway on which a high-performance sports saloon will (briefly) exceed 180 km/h (112 mph). Even the legendarily extreme Nurburgring Nordschleife, with its exceptional 20 km length and 73 to 154 corners (depending on how you count them), only has 8 sections (mostly very short) where the very fastest performance saloons will touch speeds above 200 km/h (124 mph).

Thus, even for the small percentage of performance saloon owners who might want to track their personal vehicle occasionally, acceleration up to speeds of around 100 mph (161 km/h) is much more relevant for overall performance than acceleration at speeds beyond that. How does the Taycan maintain relatively strong acceleration at higher speeds? It uses 2 forward gears. All Teslas (apart from a few early Roadster prototypes) only use a single forward gear.

Jonny Smith did not report detailed results of the repeatability of acceleration, but did note that he completed 30 acceleration runs, and didn’t mention any noticeable throttling of performance. Porsche’s account of the test is slightly more reserved. They say that Jonny did 26 successive runs of 0–200 km/h (0–126 mph) acceleration. The average time for each run was “just under 10 seconds” and the variance between fastest and slowest runs was just 0.8 seconds. That’s impressive consistency over many repeated runs, as well as impressive acceleration through to higher speeds.

Screenshot from Fully Charged’s video — Fully Charged/YouTube

Whilst the Model 3 Performance, with its efficient cooling circuits, could likely demonstrate consistent acceleration several times without encountering thermal limitations, 26 successive times has not been documented, so far as I’m aware. The number of times anyone could conceivably want to do this in practice is of course much less. Porsche’s point was to try to troll Tesla, whilst actually its design decision was influenced by something germane. (See what I did there?)

The Autobahn Use Case
Ahh, the exoticism of the Autobahns.

The actual practical design brief of the Taycan is its sustained high-speed performance, absolutely essential to acceptance in the home market, especially at this price point. Porsche says that (likely largely thanks to the two forward gear setup) the top-end Taycan will be able to sustain cruising at its top speed of 162 mph (261 km/h) for as long as is practically required on the Autobahn.

In practice this likely means designed to run at top speeds for periods of up to around 10 minutes or so, since inevitable traffic means having to back off from high speeds at least this frequently. Even at night, it’s actually very rare to get runs of more than 2 or 3 minutes at these kinds of speeds (covering ~13 km) without needing to slow a bit to safely pass haulage trucks, similar commercial traffic, or other road users (most Autobahns are two lanes only). Nonetheless, the ability-in-principle to sustain prolonged high speeds is an understandable and indeed necessary design goal to give a comfortable feeling to German consumers used to occasional fast cruising in sport sedans and coupes. This is Porsche’s home market, after all.

Tesla Battery Guru Jeff Dahn Claims New Lithium-Ion Cell Outperforms Solid-State Batteries

Tesla watchers know that Jeff Dahn and his team at Dalhousie University near Halifax, Nova Scotia, are world leaders in lithium-ion battery research. For years, Dahn worked exclusively for 3M, but when that arrangement ended, Tesla swooped in and signed a contract for Dahn to work for the Silicon Valley car/tech/energy company.

For years, the Holy Grail of battery research has been making solid-state battery cells that replace the liquid electrolyte in conventional cells with solid materials. Solid-state batteries are believed to be cheaper to produce, have higher energy density, and have a longer lifespan than conventional lithium-ion batteries. Well, if someone can crack the final code for commercially viable cells.

In addition, solid-state batteries are less like to catch fire or explode if they get too hot. That in turn means electric car manufacturers can make simpler, less costly cooling systems for their battery packs, driving down the cost of EVs. It also reassures the public their shiny new electric cars aren’t going to explode in the garage, as recently happened to the owner of a Hyundai Kona EV in Canada.

Research published by Dahn and his team in the journal Nature Energy on July 15 reveals they have created new lithium-ion pouch cells that may outperform solid-state technology battery. Here’s the abstract of that research report:

“Cells with lithium-metal anodes are viewed as the most viable future technology, with higher energy density than existing lithium-ion batteries. Many researchers believe that for lithium-metal cells, the typical liquid electrolyte used in lithium-ion batteries must be replaced with a solid-state electrolyte to maintain the flat, dendrite-free lithium morphologies necessary for long-term stable cycling.

“Here, we show that anode-free lithium-metal pouch cells with a dual-salt LiDFOB/LiBF4 liquid electrolyte have 80% capacity remaining after 90 charge–discharge cycles, which is the longest life demonstrated to date for cells with zero excess lithium. The liquid electrolyte enables smooth dendrite-free lithium morphology comprised of densely packed columns even after 50 charge — discharge cycles. NMR measurements reveal that the electrolyte salts responsible for the excellent lithium morphology are slowly consumed during cycling.”

Those pesky dendrites are the bane of lithium-ion batteries. They are little projections like stalagmites in caves that can poke through the insulating layer inside individual cells, leading to short circuits and potential fires. Eliminating them would be a big step forward, particularly for use in electric vehicles.

Is Tesla on the verge of replacing the cylindrical cells in its battery packs with Jeff Dahn’s pouch cells? Not just yet. There is a lot of research and testing left to do before they becomes suitable for commercial production, but they may signal an important step forward for energy storage in the years ahead.

Below is a video of Dahn when he won the prestigious National Sciences and Engineering Research Council of Canada award in 2017. Here is a fellow who knows what he is talking about. If he says pouch cells can outperform solid state cells, we should pay heed.

Tesla Granted New Patents For Curved & Textured Solar Roof Tile Manufacturing

Facebook

August 9th, 2019 by Kyle Field

Tesla was just granted a new series of patents that shed some light on the techniques it will use on its upcoming curved and flat solar roof tiles. These design techniques will presumably be employed as Tesla moves towards the first commercial version of Tuscan-style solar roof tiles, which are expected to move into mass production a bit later than the Tesla solar roof tiles that have just been installed on my roof.

Curved Solar Roof Tile Design
The first of the three new patents, US 2019 245 478 A1, details a few of Tesla’s strategies for implanting flat solar cells into the curved solar roof tiles that look like more traditional Spanish roof tiles. From the filing, we can see that Tesla is planning to actually embed the flat solar cells into the curved bell shape of the tiles. To do this, Tesla has developed a tile that is rounded on the exposed surface, but flat on the inside to accommodate flat strips of solar cells.

According to the filing, the tiles will be comprised of, “a transparent front cover having a first surface and a second surface, wherein the first surface comprises at least one portion that is convexly curved, wherein the second surface comprises a plurality of flat facets, and wherein the flat facets are arranged to follow the contour of the at least one convexly curved portion of the first surface.”

Taking this approach could allow Tesla to build solar cells into more surface area than would be possible on a flat roof made of solar roof tiles, but with the tradeoff that only a portion of the cells would be directly facing the sun at any point in time.

The filing discusses a curved solar roof tile design that supports both pre-wired solar modules as well as solar roof tiles that make the electrical connection to the home electrical circuit through a special connector with the adjoining panels (806 and 808 in the graphic below). Devising a system where solar roof tiles could effectively be installed as easily, quickly, and reliably as traditional roofing tiles could drastically lower the incremental cost to install a solar roof system.

The reliability of the methodology has to be a key concern for a solar roofing system that isn’t just bolted into an existing roof, but that must function as both a roof and an electrically connected solar system simultaneously for the life of the home.

Tesla Solar Roof Tile Manufacturing
Tesla’s ambitious move into building-integrated photovoltaics challenged the existing mindset that solar was something to be bolted onto the outside of homes, to live outside the envelope of the home. Instead, Tesla sought to recreate the aesthetic of traditional roofing tiles with four primary form factors: textured, smooth, Tuscan, and slate.

A new patent filing (US 2019 241 455 A1) from Tesla gives us some insights into how Tesla plans to produce some of these tiles, including a few options for different manufacturing techniques. The first technique details a stamping approach, where flat solar roof tiles are stamped between a flat bottom mold and a textured surface mold.

The technique could conceivably be used for rounded Tuscan tiles, and might even be the best approach for such a tile, given the round surface on top and the complex angled flat interior surfaces. It is easy to imagine this technique being used to produce one of Tesla’s slate solar roof tiles.

The second method shows a method where glass is pressed between two rolling surfaces, each with its own texture.

The patent filings come as Tesla puts the finishing touches on version 3 of its solar roof tiles. To date, only textured solar roof tiles have been installed on any customer homes. Tesla’s sales team told CleanTechnica reader jjn1056 that the Tuscan tiles might be available in December or January, but as with many things Tesla, that has to be taken for a grain of salt until they’re actually bolted down and on the roof.
