The reason for 24 volts is that my controller requires 24 volts on its inputs so it has a seperate DC-DC converter. This is not as big a nuisance as it first seems because the inputs on the controller are not isolated from the traction pack, the GND terminal is connected to B- internally in the controller. I am isolating all my inputs and outputs going to and from the controller and my managent module, from the vehicle, to keep the traction pack earth floating and seperate from the vehicle chassis.
I am using regen. The Kelly controller has 2 ways of doing this. It can have variable regen through a 0-5v hall sensor, I had thought of using the clutch pedal. The other option is fixed regen, which can be adjusted with the PC configuration software. I have gone this route and wired it to the brake switch. When I first touch the brakes I get around 50 amps of regen which slows the car nicely. There is a spot between when the brake switch activates and the brakes actually engage that gives regen without using the brakes.
I will investigate the current sensor options later, for now I will borrow the e-meter from the Volvo after I have finished the wiring.
EDIT: I have programmed all the slaves with V1.08 and connected the charger for a full pack charge. Hopefully it all works as planned!
