Hello David and others. May I suggest a proportional regen input? Allowing the motor to spin freely and only apply proportional regen when pressing the brake pedal is more efficient, in my estimation, than throttle regen.

Something like a pot can be used to drive how much regen is applied. Jack Rickard from EVTV has used a hydraulic pressure sensor on the brake line and says it works well. A 0-5V input to get 0-100% regen (or something else programmable)

You're still designing the controller so I imagine a detailed schematic is not available. Do you have a block diagram to show components? Things like the IGBT drivers, current sensors, logic/DSP, DC-DC converters, programming interface, etc?

Thanks,
JR
