The invention belongs to the technical field of vehicle battery energy management, and particularly relates to a vehicle power supply system and a storage battery charging control method and device. The method comprises the steps that when it is detected that a vehicle mechanical handle switch is closed and a vehicle stands, if a power battery of the vehicle is in a starting state, the power battery is controlled to charge a storage battery through a DCDC converter, so that the storage battery can keep high voltage, the service life of the storage battery is prolonged, and the safety of the vehicle is improved. The frequency of starting the power battery especially when the storage battery is lack of electricity is reduced, the electricity supplementing control logic is simplified, the operation and maintenance cost is reduced, a mechanical switch does not need to be specially switched off, the storage battery is prevented from being lack of electricity when the vehicle stands for a long time while intelligent parts are used, use is more convenient, and the vehicle using experience of a user is improved.

    本发明属于车辆电池能量管理技术领域,具体涉及一种车辆电源系统、蓄电池补电控制方法及装置。该方法包括:检测到车辆机械手柄开关闭合且车辆静置时,若车辆的动力电池处于启动状态,则控制动力电池通过DCDC转换器为蓄电池进行充电,使得蓄电池能够保持较高的电压,提高了蓄电池的使用寿命,并且减少了蓄电池亏电时特别去启动动力电池的频率,简化了补电控制逻辑,降低了运维成本,也无需专门断开机械开关,能够使用智能零部件的同时避免车辆长时间静置时蓄电池亏电,使用更加方便,提高了用户的用车体验。
