Engineers use battery management systems (BMS) to prevent problems that occur in Li-ion batteries when they are over-charged or over-discharged, including premature capacity loss and thermal events. A BMS ensures precise control and keeps the individual cells balanced, which is critical to extracting the most useful energy from a pack. Fortunately for EV systems designers,… Read more »

EV Fleet CEO on building a highway-capable light-duty all-electric truck
There are a lot of great opportunities for companies building EVs for niche markets, but getting an independent automotive startup off the ground is anything but easy. EVs can be very practical from a financial point of view. So it’s a bit of a shame that for the world’s most practical vehicle buyer – the… Read more »
Self-heating lithium-ion battery aims to conquer winter range anxiety
One of the drawbacks of lithium-ion batteries is that they tend to suffer power loss in cold weather. At temperatures below freezing, charging is slower, regenerative braking is restricted and vehicle range can be reduced. Now researchers from Penn State and spin-off company EC Power have developed a battery that avoids these problems by self-heating… Read more »
DOT announces major push to advance autonomous vehicles
DOT Secretary Anthony Foxx introduced a new federal strategy to help develop autonomous driving technology at the Detroit auto show, joined by execs from Tesla, Google, Ford, GM, Delphi and other automotive firms. “If the government doesn’t change its ways, drivers in the future will not be moving on the highways – they will be… Read more »
Carlos Ghosn talks EVs: Governments may be leading now, but consumers will follow
There’s been a lot of talk lately about whether automakers that aren’t named Tesla are truly committed to zero-emission vehicles. Yes, they’re building EVs, but many observers believe that this has more to do with government regulations than customer demand – a controversial article in The Detroit News recently made this point. At the North… Read more »
Chevy designed the Bolt with performance in mind (not just range and price)
In the eyes of the EV media at least, the Chevrolet Bolt EV, scheduled to go on sale later this year, is a historic vehicle. It’s the first to deliver the range and price point that pundits have been saying represent a “tipping point” for EV sales. However, GM designed the Bolt with more than… Read more »
Chrysler’s new hybrid minivan has a plug (but don’t tell anyone)
Chrysler holds an enviable position atop the popular minivan segment, and the less respectable distinction of being the leading electrification skeptic among major automakers. So the company’s new plug-in hybrid minivan, which is scheduled to arrive in showrooms in late 2016, is something of a milestone. The Pacifica Hybrid, which Chrysler calls the industry’s first… Read more »
Faraday Future’s Variable Platform Architecture – a modular skateboard to build an EV on
EV startup Faraday Future’s carmaking prowess has yet to be tested, but it has already revealed some impressive marketing talent. After milking several months of mystery, the company unveiled its FFZERO1 supercar concept at the recent CES in Las Vegas. The event was one of the hottest tickets at a show that has reinvented itself… Read more »
The first of a new generation: Chevrolet unveils the 2017 Bolt EV
GM CEO Mary Barra introduced the 2017 Chevrolet Bolt EV in a dazzling sound-and-light show at CES in Las Vegas. The company has earned the right to a little pomp: the Bolt is the first EV to offer a 200-mile range at a price tag “around $30,000” after tax incentives, and it will be a… Read more »
