Has anyone done anything like that? A timer, so when you turn on "ignition" first a relay to the precharge resistor turns on. Then after 2 seconds or something, the contactors turn on.
Or better, some kind of a differential voltage sensor. So when the voltage before and after the contactors are close to equal, the contactors turn on.
Is there circuits like that to buy, or how could one be built?
