A battery management system (BMS) controls lithium battery access on a utility vehicle is disclosed. 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.
一种控制多用途车辆上的锂电池通路的电池管理系统(BMS)。该BMS包括与锂电池耦合的电池接口、与多用途车辆的一负载组耦合的负载接口、和与电池接口和负载接口耦合的控制电路。该控制电路响应于睡眠事件而将电池接口从负载接口机械地断开连接。另外,在电池接口从负载接口机械地断开连接后,响应于唤醒事件而将锂电池接口重新机械连接至负载接口。另外,在电池接口重新机械连接至负载接口后,控制电路保持电池接口与负载接口之间的连接,以通过电池接口和负载接口将电力从锂电池输送至多用途车辆的负载组。
