A control strategy for an electric vehicle battery system is described that combines active cell temperature balancing. In one example, a method includes employing, by a system operatively coupled to at least one processor, a smart cell system to power one or more electrical systems of a vehicle, the smart cell system including a plurality of battery cells. The method further includes controlling, by the system, operation of the battery cells according to a control protocol that causes an increase in the temperature of the subset of battery cells based on the temperature of the subset of battery cells being below a threshold temperature. In one example, a control protocol may include circulating current between a subset of battery cells and/or other battery cells excluded from the subset, actively discharging the subset of battery cells, and redistributing power to other battery cells excluded from the subset, among others.

    描述了用于电动交通工具电池系统的控制策略,其结合主动单体温度平衡。在一个示例中,一种方法包括由操作性地耦合到至少一个处理器的系统采用智能单体电池系统以向交通工具的一个或更多电气系统供电,该智能单体电池系统包括多个电池单体。该方法进一步包括由系统根据控制协议控制电池单体的操作,该控制协议基于电池单体的子集的温度低于阈值温度而导致升高电池单体的子集的温度。在一个示例中,控制协议可包括在电池单体的子集和/或从子集排除的其它电池单体之间循环电流,主动地对电池单体的子集放电,以及将电力重新分配到从子集排除的其它电池单体,以及其它。
