Hello
Is anyone aware of a simple timer based solution for connecting a precharge resistor for a certain amount of time before connecting the main contactor? I want my BMS to totally disconnect the pack at LVC but I have several capacitive loads (inverter/charge, motor controller, DCDC) so I'm concerned the inrush is going to weld my contactor when it turns on. I'm thinking I could do it pretty easy with some relays if there was something that just added a few second delay on the main contactor.
Cheers,
Curtis
