The invention relates to the technical field of battery management, and discloses a standby battery management device and method, a program product and a vehicle, the device comprises an acquisition module, a processor and a communication module; the acquisition module acquires the current charging current and the current charging voltage of the standby battery under the charging working condition; the processor determines an initial SOC value of the standby battery, and determines a current SOC value of the standby battery according to the initial SOC value, the current charging current and the charging duration; current reference charging current corresponding to the current charging voltage is determined, and whether charging continues or not is determined by comparing the current reference charging current with the current charging current; generating current state information including a current SOC value under the condition that charging is continued; and the communication module reports the current state information. According to the invention, the voltage-current hybrid verification of the standby battery can be realized, so that whether the standby battery is fully charged or not can be accurately determined, and the overcharge of the standby battery can be effectively prevented.

    本发明涉及电池管理技术领域,公开了备用电池的管理装置、方法、程序产品及车辆,该装置包括:采集模块、处理器和通信模块;采集模块获取备用电池在充电工况下的当前充电电流和当前充电电压;处理器确定备用电池的初始SOC值,根据初始SOC值、当前充电电流和充电时长确定备用电池的当前SOC值;确定与当前充电电压相对应的当前基准充电电流,通过比较当前基准充电电流和当前充电电流确定是否继续充电;在继续充电的情况下,生成包括当前SOC值的当前状态信息;通信模块上报当前状态信息。本发明可以实现对备用电池的压流混合校验,从而能够比较准确地确定备用电池是否充满,或发生脱落问题,有效防止备用电池过充。
