GM says equipping the next-gen Chevy Bolt EV with LFP batteries will save billions

EV enthusiasts were disappointed at GM’s decision to discontinue the popular (if a bit dull) Chevy Bolt EV last year. In hindsight, the move may have been premature—the new Ultium EVs that were supposed to replace the Bolt in GM’s lineup have been delayed, causing the company to post embarrassingly low EV sales figures for… Read more »

GM hires EV superstar Kurt Kelty as Vice President of Batteries

It’s plain to anyone who follows the auto industry that there are pro-EV and anti-EV factions at every legacy automaker. For the last three decades, the OEMs’ interest in EVs has flapped this way and that in the winds of quarterly earnings and political shifts. Last fall, the “let’s wait awhile” contingent appeared to have… Read more »

GM’s rosy year-end figures obscure the fact that legacy automakers are in deep trouble

Duplicitous doublespeak has become de rigueur dialect in the auto industry. “We remain committed to an all-electric future,” says GM as it announces a rollback of its electrification plans. “We strongly believe in EVs,” say auto dealers as they support efforts to slow the EV transition. “The greatest responsibility for us as a company is… Read more »

Kia EV9 and Volvo EX30: Are they 2024’s most important EVs?

One’s a three-row midsize SUV under $60,000; the other’s a compact hatchback that starts in the mid-30s. Now we’ve driven both. Choosing “best of” or “most important” new cars is always dicey, and doubly so with electric vehicles. New entries are announced virtually every month, and picking the 2025 models that will be most important… Read more »

GENIUS allows vehicle-to-home bidirectional charging

GENIUS, a microgrid controller by Koben Systems, is designed to make vehicle-to-home (V2H) technology more flexible for EV owners, as energy can be automatically transferred from the vehicle to any load, or to the grid. This upgraded solid-state technology reduces peak electricity consumption and power disruptions in the overtaxed grid infrastructure, according to the company…. Read more »

GM invests in battery materials innovator Mitra Chem

GM has invested $60 million in a Series B financing round for Mitra Chem, a Silicon Valley-based battery materials innovator. GM and Mitra Chem will develop new iron-based cathode active materials (CAM), namely lithium manganese iron phosphate (LMFP), to power EV batteries compatible with GM’s Ultium Platform EV propulsion architecture. GM’s funding will help Mitra… Read more »

EVgo, in partnership with GM, opens its 1,000th charging stall

The 1,000th charging stall was opened in the Chicago suburb of Woodbridge recently as part of an ongoing collaboration between US charging network EVgo and General Motors (GM). The partnership began in 2020 and was expanded in 2021. Its goal is to install 3,250 fast-charging stalls in major metro markets. Installations to date, says EVgo,… Read more »

GM offers details of V2H charging hardware (but no V2H-capable EV yet)

Vehicle-to-home (V2H) charging technology, which enables an EV to serve as a home backup power source, is expected to be a big selling point for automakers. In fact, GM just released some details about its upcoming bidirectional V2H charging hardware, even though it does not yet have any V2H-capable vehicle on offer. The Ultium Home… Read more »

Thermal runaway in EV battery packs: designing a mitigation strategy

Aspen Aerogels’ cutting-edge materials protect against thermal runaway Thermal runaway occurs inside a battery cell through a fault, a crash scenario or some other defect that causes the cell to release thermal energy through chemical reactions. That thermal energy increases the temperature of the cell, the increased temperature drives faster kinetics, and more heat is… Read more »

RAM 1500 REV electric pickup truck: concept meets reality

Despite a showy concept, Ram’s EV pickup doesn’t look that different than its gasoline versions. Is following Ford’s lead the right move? It was clear that the striking Ram 1500 REVolution Concept, unveiled at January’s Consumer Electronics Show (CES) in Las Vegas, foreshadowed a production electric Ram 1500 within the next couple of years. Ram… Read more »
