The invention discloses an active equalization control method and system for a power battery and a vehicle-mounted terminal controller, and the method comprises the steps: receiving the equalization time of the power battery transmitted by a battery manager when an electric vehicle is powered off, the equalization time of the power battery is determined by the battery manager according to the state information of the power battery when the electric vehicle is powered off; determining timed wake-up interval time according to the power battery equalization time; and when the timed wakeup interval time is up, waking up the vehicle control unit so that the vehicle control unit can control high-voltage electricity on the electric vehicle to carry out power battery active equalization according to the power battery equalization demand sent by the battery manager after waking up the battery manager. Therefore, the problems that the high-voltage power-on time of the electric vehicle is short due to the running working condition, and the balance requirement of the power battery cannot be met are solved, the service life of the power battery is prolonged, and the endurance mileage of the electric vehicle is prolonged.

    本发明公开了一种动力电池主动均衡控制方法及系统、车载终端控制器,其中动力电池主动均衡控制方法包括:接收电池管理器在电动车辆下电时发送的动力电池均衡时间,其中,动力电池均衡时间由电池管理器在电动车辆下电时根据动力电池的状态信息确定;根据动力电池均衡时间确定定时唤醒间隔时间;在定时唤醒间隔时间到达时,唤醒整车控制器,以便整车控制器唤醒电池管理器后根据电池管理器发送的动力电池均衡需求控制电动车辆上高压电进行动力电池主动均衡。由此,避免了因行车工况导致电动车辆的高压上电时间短,无法满足动力电池均衡需求的问题,延长了动力电池的使用寿命以及电动车辆的续航里程。
