Hello ES members,
I recently received a 72V 40A Infineon controller purchased from EM3ev. Almost everything on it works great e.g. cruise, 3 speed switch, e-brake etc. The hall and phase wires were a bit short but I replaced them with a longer wiring harness from my dead controller.
Anyway, the EM3ev controller supposedly comes with regenerative braking via a white wire you plug in to another white wire on the outside of the controller. Regenerative braking is supposed to be enabled when it's plugged in.
Right now, when I've enabled regenerative braking, all it seems to do is cut the throttle signal while the motor is running. The strange part is, there's definitely no regeneration going on (while the e-brake is engaged) when the motor is running FORWARD. However if I'm holding the e-brake/regeneration button, the motor is difficult to turn by hand BACKWARDS.
On the controller, there are jumpers marked EBS+ and EBS-. I have no idea what these 2 jumpers do, and the documentation that came with the controller leaves much to be desired. The controller came with BK soldered to ground (assuming this is the motor cut-off), and EBS- is soldered to ground.
Does anyone know what is going on or how to enable regenerative braking, or please tell me what the jumpers EBS+ and EBS- do? Could it be detecting a freshly charged battery pack and not engaging the regeneration?
Cheers.
