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 »

2022 Ford F-150 Lightning First Drive: Ford’s most valued model is now electric

Ford knows trucks, and demand for its F-150 Lightning shows truck buyers may not be as afraid of EVs as many think. The 2022 Ford F-150 Lightning pickup truck may be the first real mass-market electric vehicle sold in the US. Used by individual owners and businesses alike, pickups are a massive part of the… Read more »

2022 Lucid Air: The makers of the first 500-mile EV should be taken seriously

Created by engineers with years of EV experience, the 2022 Lucid Air is a stunning debut that confronts Tesla—and Mercedes-Benz—with a new competitor. It’s been a long time coming, but the 2022 Lucid Air has been worth the wait. The new carmaker’s all-electric luxury sedan not only competes directly with the aging Tesla Model S,… Read more »

A closer look at minimizing charging losses: The charger (Part 2)

In the previous article, we looked at the various losses incurred on the AC side of the circuit while charging an EV’s battery (from the breaker in the load center to the EVSE inlet on the EV), as well as things that could be done to minimize them, either by the OEM, the electrical contractor… Read more »

Infinitum Electric brings its PCB stator technology to EV motors

Infinitum Electric says its axial flux motors with printed circuit board stators offer weight reduction, cost reduction and efficiency gains. Batteries are getting a lot of media coverage these days—they represent a rapidly-developing technology that’s seen as the key to the electrification of transport. Motors, however, are considered a fairly mature technology, and the humble… Read more »

2021 EV Charging Infrastructure Benchmark: Electrify America top digital platform, Tesla Superchargers top location experience

This year, Blink and Tesla Superchargers were added to the list of charging networks tested in 2020: Electrify America, EVgo, ChargePoint, EV Connect and Greenlots.  Electrify America earned the top score in the Digital Platform category, as well as the top combined score for both categories. Tesla Superchargers received the top score in the Charging… Read more »
