The EV Transition Explained

Why not? EVs lack tailpipe emissions, sure, but producing, operating, and disposing of these vehicles creates greenhouse-gas emissions and other environmental burdens. Driving an EV pushes these problems upstream, to the factory where the vehicle is made and beyond, as well as to the power plant where the electricity is generated. The entire life cycle… Continue reading The EV Transition Explained

Crowdsourcing Bridge Inspection

Apps that tap into smartphone sensors to monitor human health and diagnose diseases abound. Now, engineers have come up with a way to use smartphone data to reveal if bridges are ailing, allowing repairs before they fail. Using such crowdsourced data as part of maintenance could increase a new bridge’s lifespan by over fourteen years… Continue reading Crowdsourcing Bridge Inspection

Solving Automotive Design Challenges With Simulation

The development of new hybrid and battery electric vehicles introduces numerous design challenges. Many of these challenges are static or low-frequency electromagnetic by nature, as the devices involved in such designs are much smaller than the operating wavelength. Examples include sensors (such as MEMS sensors), transformers, and motors. Many of these challenges include multiple physics.… Continue reading Solving Automotive Design Challenges With Simulation

Chopper Rocket Chasers Played “Catch Me if You Can”

Update 4 Nov. 2:45 p.m. EDT:Rocket Lab says its launch was successful, but booster recovery was not. It says it lost telemetry signals from the descending first stage during reentry. “As standard procedure, we pull the helicopter from the recovery zone if this happens,” a company spokesperson said. “If at first you don’t succeed….” Rocket… Continue reading Chopper Rocket Chasers Played “Catch Me if You Can”

Fast-Charging EV Batteries With Nickel Foil

Utrecht, a largely bicycle-propelled city of 350,000 just south of Amsterdam, has become a proving ground for the bidirectional-charging techniques that have the rapt interest of automakers, engineers, city managers, and power utilities the world over. This initiative is taking place in an environment where everyday citizens want to travel without causing emissions and are… Continue reading Fast-Charging EV Batteries With Nickel Foil

Autonomous Vehicles: Ensuring No Data Is Lost in Transmission

As the automotive industry navigates a new era of self-driving cars, every second matters. The information obtained from sensors and electronics must be given to the main CPU as precisely and quickly as possible. To ensure optimal safety and performance, it’s imperative that no data is lost in transmission. To achieve this, we’re increasingly relying… Continue reading Autonomous Vehicles: Ensuring No Data Is Lost in Transmission

Nighttime Charging of EVs May Overburden the Grid

Evolution of In-Vehicle Networks

Developments in Advanced Driver-Assistance Systems (ADAS) are creating a new approach to In-Vehicle Network (IVN) architecture design. With today’s vehicles containing at least a hundred ECUs, the current distributed network architecture has reached the limit of its capabilities. The automotive industry is now focusing on a domain or zonal controller architecture to simplify network design,… Continue reading Evolution of In-Vehicle Networks

Quantum Sensors Could Quell EV Range Anxiety

A major concern when it comes to electric vehicles is how far their batteries will let them drive. Now, scientists in Japan reveal that diamond quantum sensors can help improve electric-vehicle battery-monitoring accuracy by a hundredfold or more, potentially significantly boosting their driving range. Electric vehicles monitor how much charge is left in their batteries,… Continue reading Quantum Sensors Could Quell EV Range Anxiety
