All-Electric Flying Car Gets Go-Ahead for Testing

Ally Winning, European Editor, PSD

“I was told we’d all have flying cars by now” is a common put down among those cynical of potential technological advancements. Up until now, they may have had a point, but with the news of the FFA granting Alef Aeronautics legal permission to test its Model A vehicle both on the road and in the air, they ma

Do EVs Still Require A 12V Battery?

Pat Kowalyk, Field Application Engineer, Vicor

Look under the hood of an electric vehicle and you may be surprised to find a conventional 12V lead-acid battery, or an additional 48V battery. You may wonder why does an EV need a conventional battery when there’s a 400V or 800V battery already in the vehicle to power the motors? Today the 12V or 48V batteries po

Wireless Communication in Automotive BMS

Tomas Urban – Systems Engineer in Automotive, Texas Instruments

Batteries in EV/HEV reach nominal voltages of 400 V or 800 V. The batteries are typically organized in modules that are managed by a dedicated battery management integrated circuit (BMIC). Typically, one BMIC can monitor up to 16 cells connected in series. The main role of the BMIC is to periodically measure th

All Charged Up

Ally Winning, European Editor, PSD

Welcome to the August issue of Power Systems Design Europe. Infrastructure and charging are two of the main reasons that the adoption of electric vehicles is not more widespread. If owners cannot charge vehicles at home, and even then at a slow rate, they usually have to charge at a commercial charging station. Th

Getting Electric at the Close of the Summer

Jason Lomberg, North American Editor, PSD

Welcome to the August issue! Summer’s nearly over, and here’s hoping you were able to holiday somewhere fun, possibly by availing yourself of our topic this month (EVs, Hybrids, and Charging Infrastructure). My personal vehicle is a hybrid, though I haven’t ruled out graduating to an electric vehicle,
