In a video, EE World spoke with a power-supply applications engineer about why EV batteries use such high voltages and how to test them. Batteries are perhaps the most expensive component of an electric vehicle. Typically producing 800 V to 900 V, batteries deliver the power needed move the vehicle. Of course, EV batteries need testing so assure auto makers and drivers … [Read More...] about EV battery tests involve lots of power
