Prohelion EV Driver Controls
Prohelion's EV Driver Controls is the device responsible for controlling the motor controllers. Details can be found in the user's manual. You'll notice that the manual does not specify the device's CAN broadcast messages. This is because, like the BMS, this device is programmable. The current settings define the following CAN frames:
