World Rallycross racing championship goes electric
EVs have firmly established themselves in the racing world—Formula E has been delivering thrills for eight seasons now, and the more rough-and-tumble Extreme E is midway through its second season. Electric racers, both 4-wheeled and 2-wheeled, have distinguished themselves at the yearly Pikes Peak Hill Climb. Teslas have been shaking up the street racing subculture…. Read more »
What does the bZ4X recall and buyback mean for Toyota’s EV efforts?
What on Earth is going on at Toyota? It was bizarre enough that the company that introduced the ground-breaking Prius (and has since sold over 15 million hybrids) had in recent years pursued a flat-earth strategy, bad-mouthing EVs at every opportunity and lobbying hard against government climate measures. Then came the news that the world’s… Read more »
The promise of wireless charging: smaller batteries, longer battery life, fewer charging stations
Q&A with Momentum Dynamics Wireless charging is nothing new—Charged has covered wireless EV charging since at least 2011—but it may be that its true value is only coming into focus now, as more and more commercial and transit fleets are electrifying. There are many reasons (safety, reliability, liability) that a fleet operator might not want… Read more »
The EV raw materials crunch: How bad, how long, how to solve it?
This article originally appeared in Issue 60: April-June 2022 Subscribe now Every new technology must overcome a series of temporary constraints on its way to widespread adoption. Since modern EVs appeared a decade ago, they’ve motored past many of these bottlenecks, (or hurdles, or roadblocks—pick your preferred metaphor).

There’s broad agreement that the changes will help to speed EV adoption, but there’s also concern that some provisions of the law could be counter-productive, at least in the short… Read more »
A closer look at brushed AC motors in EVs
Everything old is new again: BMW’s fifth-generation eDrive features a wound-field synchronous AC motor Brushed DC (and AC/DC universal) motors are much maligned for a number of reasons, but one of the chief—if, perhaps, somewhat exaggerated—complaints is that the graphite brushes, and the segmented copper commutator they ride on, wear out over time, all the while producing… Read more »
EV sales hit new record in Q2, as legacy vehicles struggle
The legacy auto industry is crying the blues—US new-vehicle sales in the second quarter were up only a tiny bit from the previous quarter, and down over 20% from Q2 2021. However, the new auto industry is doing very well, thank you. Kelley Blue Book tells us (via Cox Auto) that sales of pure EVs… Read more »
ONE’s hybrid battery pack combines the best aspects of two chemistries to deliver 600 miles of EV range
Q&A with ONE CTO Dr. Steven Kaye. There is a wide range of characteristics that describe the performance of any given battery chemistry: energy density, specific energy, specific power, discharge efficiency, self-discharge rate, cycle life, calendar life, and—not the least important—cost. Some types of Li-ion chemistries are really good in a few characteristics but fall… Read more »
