Integrating the precharge and monitoring the voltage is really excellent. It's one less thing to hookup and get right. Also means the controller can energise the main contactor with confidence that the precharge is done. Prevents that issue of the precharge circuit silently failing and the driver blissfully driving the car with the main contactor taking a beating each time the system is started.
Does the new board also contain the precharge resistor? If so what value? I imagine it would be fairly easy for the builder to add whatever value suited their set up.
