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

Figure 1: Transient test comparison: 48V-to-12V at 75A compared to a 12V battery. The Vicor NBM2317 power module response to a 50A load is three times faster than a standard 12V battery

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

Figure 1: Wired vs Wireless BMS

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
