Electric vehicle (EV) adoption is growing, but the convenience of internal combustion engine (ICE) vehicles is still the benchmark. Exceeding market expectations depends on continual innovation in batteries. Intensive testing of EV batteries is crucial and EV manufacturers, suppliers, and test facilities need to make the best use of their battery test lab to ensure… Read more »

Proterra battery technology to power El Dorado National’s next-gen electric transit buses
Commercial EV innovator Proterra (NASDAQ: PTRA) will provide its battery technology to El Dorado National (ENC), a subsidiary of the REV Group, to power ENC’s second-generation electric transit buses. Under a new, multi-year supply agreement, Proterra will supply its S-Series battery system to power ENC’s Axess Battery Electric Bus (EVO-BE), which will be produced in… Read more »
EV battery testing: Improve your lab design and operation (Webinar)
EV adoption is growing, but the convenience of internal combustion engine (ICE) vehicles is still the benchmark. Exceeding market expectations depends on continual innovation in batteries. Intensive testing of EV batteries is crucial and EV manufacturers, suppliers, and test facilities need to make the best use of their battery test lab to ensure fast development…. Read more »
Minnesota nickel mine faces environmental justice challenges
Let’s get this straight right away: this is not one of those “EVs’ Dirty Little Secret” articles. We know that e-mobility has an environmental footprint, but it’s far smaller than that of legacy petroleum-powered vehicles, as countless studies have shown. On the other hand, it’s critical that every step of the EV supply chain be… Read more »
Webinar: Why Model Batteries?
A detailed understanding of battery technology and the underlying physics processes is necessary to design high-performance, durable, and safe batteries. Physics-based modeling is being used for building accurate simulations of batteries, incorporating different aspects through predefined physics-based interfaces, from detailed structures in a battery’s porous electrode to the battery pack scale, including thermal management systems….

Miami-Dade to buy 42 Proterra electric transit buses and 75 chargers
Miami-Dade Transit has ordered 42 electric transit buses from commercial vehicle OEM Proterra (NASDAQ: PTRA). The agency will also install 75 Proterra chargers across three bus depots. The 42 Proterra ZX5+ 40-foot e-buses pack a total of 19 megawatt-hours of battery storage capacity, and the charging installation will crank out a total of 9 megawatts… Read more »
VIA Motors secures order for 2,000 Class 3 electric chassis cabs
VIA Motors is one of the most venerable names in the commercial EV space—we’ve been covering the company since its 2010 founding. The company got a lot of early press, thanks to its mediagenic chairman, the unlikely EV pioneer Bob Lutz, but later dropped off the radar. The commercial EV market has been frustratingly slow… Read more »
Quebec lithium mine faces many hurdles to reach production
As EV adoption grows, it’s plain that more EV raw materials will need to be mined and processed in North America (and Europe). But bringing a new mine into production is a lengthy process with many potential pitfalls along the way. A lithium mine in the pine forests northwest of Montreal provides an example of… Read more »
New Hampshire utility to offer EV owners special rates in V2G program
Utilities around the country are experimenting with vehicle-to-grid (V2G) systems. Now the New Hampshire Electric Co-op plans to offer its members real-time energy rates that will allow them to earn revenue from their EVs and battery storage devices. The co-op plans to offer members a “transactive energy rate” as soon as the end of this… Read more »
Power electronics thermal limits and how to not exceed them
To someone who isn’t involved in power electronics design, it might seem unreal that the amount of power a component can handle depends more on how effectively waste heat can be removed from it than it does on the specific electrical ratings. Sure, the voltage and current ratings are important (especially the voltage rating), but… Read more »
