What is precharging? Why do EVs need it? Don't blow up your inverter!

£1 Billion is typically spent on developing a new Electric Car, the manufacturers put a whole lot of magic into EV powertrain development. A precharge circuit is very common to protect inverters and other sensitive equipment. In Power Electronics you often only get one chance to do it right, and not understanding precharging is a common way to destroy expensive inverters. Avoid that mistake by learning about it in this quick video. Starting with the circuit you remember from school, with one battery, one switch and a DC motor, we work our way through I show you why we bother with 3-phase motors I show you how the circuit is different We discover what capacitors and hungry dogs have in common You are then prepared for further research. My name is Janosch, I have built three electric cars myself and driven many miles in them. In these videos I show you what I have learnt in the process and am sharing my mistakes, missteps and acquired lessons with you. I hope they help you.
