Abstract
A motion control system controls movement of a utility vehicle. The motion control system includes an electric brake that (i) provides mechanical resistance which inhibits a motor of the utility vehicle from turning when the electric brake is unpowered and (ii) removes the mechanical resistance to allow the motor of the utility vehicle to turn when power is provided to the electric brake. The motion control system further includes a lithium BMS having a contactor that closes to provide electrical access to a lithium battery and opens to remove electrical access to the lithium battery. The motion control system further includes control circuitry coupled with the electric brake and the lithium BMS. The control circuitry directs the lithium BMS to maintain closure of the contactor to provide power from the lithium battery to the electric brake in response to receipt of a tow signal.
