摘要： 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.

摘要： A battery management system (BMS) controls lithium battery access on a utility vehicle. The BMS includes a battery interface that couples with a lithium battery, a load interface that couples with a set of loads of the utility vehicle, and control circuitry coupled with the battery interface and the load interface. The control circuitry mechanically disconnects the battery interface from the load interface in response to a sleep event. Additionally, after the battery interface is mechanically disconnected from the load interface, the control circuitry mechanically reconnects the battery interface to the load interface in response to a wakeup event. Furthermore, after the battery interface is mechanically reconnected to the load interface, the control circuitry maintains connection between the battery interface and the load interface to convey power from the lithium battery to the set of loads of the utility vehicle through the battery interface and the load interface.
