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 »
Requirements and assembly solutions for E-mobility
Sponsored by Nordson Sealant Equipment The current supply chain situation of semiconductors and also many other, much simpler components shows how important the local production actually is. Not only car manufacturers but also suppliers, which after relocating production sites abroad or even continental relocation, are now experiencing delivery difficulties, some of them considerable. Companies like… Read more »
Silicon carbide is becoming the material of choice for EV power electronics
Silicon carbide is a hot topic in the power electronics field these days. As a recent article in the New York Times explains, SiC is a wide-bandgap (WBG) material that designers are increasingly choosing to make power electronics devices more efficient. WBG advantages The WBG classification has profound implications for device behavior and performance. This… Read more »
Rivian working on 800-volt architecture, bidirectional charging, in-house drive units and battery cells
EV startup Rivian’s Q4 2021 Shareholder Letter is reminiscent of the ones we used to see from a certain other Californian EV startup in its idealistic younger days—full of forward-looking technical innovations. Rivian appears to embracing several current trends on the EV scene—going bidirectional and moving towards 800 volts, LFP cells and more in-house production… Read more »
Orange EV claims to have the most electric trucks operating in the US
Electric trucks are much in the news these days, but most of the coverage seems to focus on well-known OEMs such as Daimler and Volvo, which are just beginning to deliver e-trucks to US customers, or Tesla, which has delivered none.

Can the global battery supply chain keep up with anticipated EV demand?
As global demand for EVs increases, many are questioning the adequacy of the existing battery supply chain. A recent article in Transport Dive discusses the challenges involved in building a global supply chain that can keep up with the anticipated growth in EV production. Elon Musk said in October that a shortage of battery cells… Read more »
The technical challenges of bidirectional chargers
For years, we’ve been hearing about an EV technology that promises to be a game-changer: Vehicle-to-Grid (V2G) bidirectional charging. My recent work with one V2G charger developer, Fermata Energy, has convinced me that V2G has found its proverbial killer app: load peak shaving for commercial/industrial energy customers. This article is going to concentrate on the… Read more »
EMC for EVs: Understanding electromagnetic compatibility
Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »
