WattEV aims to operate 12,000 electric Trucks-as-a-Service and a charging network to support them by 2030

Electrifying commercial vehicles is a critical part of reducing emissions, so it’s frustrating that the pace of fleet electrification has been so slow. Viable commercial EVs have been around for years, but fleet operators insisted on conducting years-long pilots to prove their reliability. Now that phase is over, and companies are starting to place substantial… Read more »

How a motor’s operating speed, torque and control strategy affect its efficiency

Second only to power output, efficiency is one of the most fudgeable ratings that applies to traction motors for EVs (right up there with capacity and cycle life claims for Li-ion batteries…). For common 3-phase industrial AC motors, most of the specmanship shenanigans have been dealt with by NEMA (National Electrical Manufacturers Association), a voluntary… Read more »

BrightDrop: GM’s silent push into electric commercial vehicles

Upcoming electric passenger vehicles and light trucks from GM get most of the attention, but its new commercial EV brand is a quiet and very serious push too. Many US drivers now have a vague idea that General Motors is doing something with electric vehicles. They’ve seen Super Bowl ads for the GMC Hummer EV,… Read more »

Emporia’s energy management system prepares for the bidirectional EV charging future

Total control of power usage: from solar to EV and back to the house. Bidirectional charging promises to completely transform the vehicle ownership experience. Once an EV can double as a stationary storage device, it will take its place as part of an energy ecosystem that includes rooftop solar and energy management—and could even become… Read more »

Britishvolt wants to build battery gigafactories around the world

Battery “gigafactories” are under construction all over the world—and none too soon. As EV sales grow, it is critical to establish local battery production and shorten supply chains. However, state-of-the-art cell packaging and chemistries are evolving quickly these days. How will cell manufacturers future-proof their cell production facilities? How flexible will these new plants be… Read more »
