This is my first post and am curious if anybody here has any experience or advice on how to discharge a capacitor bank with 6 1F capacitors connected in parallel. I built a electric hybrid (basically electric transmission) vehicle that uses a 31hp gas engine to power a 23kW (peak) DC generator. The capacitor bank is in parallel with the generator and two VFDs and each of those is connected to a 16kW AC motor. I am currently letting the VFDs drain the capacitor bank when the engine is turned off, however that takes about 2 minutes and I am not sure if all the power is gone or the LEDs just stop blinking on the VFDs. I am looking for a quick way to safely discharge the capacitor bank if the engine and VFDs are turned off. I was looking a powered resistor but I couldn't find one big enough. I also thought about using a relay but am worried about the instant power release. I trying to keep my power/weight ratio high so a solution (if there is one) needs to be light and mobile.
