The invention provides a battery charging heat preservation control system and method. The battery charging heat preservation control system comprises a charger, a direct-current converter, a vehicle control unit and a battery management system. The battery management system is regularly awakened to detect whether the battery pack has a heating requirement or not after the battery pack is charged, if the battery pack has the heating requirement, the battery management system awakens the vehicle control unit, the charger and the direct current converter, and meanwhile, the battery management system requests the charger to output constant voltage to the battery pack; the battery pack is heated; in the heating process of the battery pack, the vehicle control unit sends out a direct-current converter enabling signal according to the high-voltage output state and the battery heating state collected by the direct-current converter, and the direct-current converter enabling signal is used for supplementing low-voltage electric energy loss.

    本发明提出了一种电池充电保温控制系统及方法,包括:充电机、直流转换器、整车控制器及电池管理系统;所述电池管理系统在电池包充电完成后被定时唤醒用于检测电池包是否存在加热需求,若电池包存在加热需求,则所述电池管理系统唤醒整车控制器、充电机及直流转换器,同时所述电池管理系统请求充电机恒压输出至电池包,用于电池包加热;所述整车控制器在电池包加热过程中,根据直流转换器采集的高压输出状态和电池加热状态发出直流转换器使能信号,用于补充低压电能损耗。
