Hi All, new project time.
Bike: Corratech e-power e28 hybrid, bosch mid drive, alfine igh and hydraulic rim brakes.
problem: controller is bricked by wrong one time initialisation code, now gives error 500
slution: gut controller and install enerton vesc foc box controller.
I will start by disconnecting the phase wires from the motor and installing a temp sensor and new phase plug, add a vesc and bypass the bms for a direct feed.
It will hopefully run sensorless as the bosch uses a single hall sensor and a magnetic code wheel on the shaft end that ill bet does not have the same pole number as the motor and is therefore junk. ill try leaving the factory controller intact without phase connections so the lighting circuit may still work. the pack is 4p10s LG MG1 2900mah 10a cells so ill try for 800 watts to start with to keep it under half the c rate of the cells.
Tomorrow illl get the vesc and battery conections soldered up and have a play with the start up boost settings until it hopefully works and post some photos. if anyone else has tried an alternative controller on a bosch let me know how it went.
