The embodiment of the invention provides a vehicle charging and distribution method and device, a storage medium and a vehicle control unit. The method comprises the following steps: acquiring the voltage of an input low-voltage system before high voltage is applied, and determining the state of a storage battery; if the storage battery is in the feed state, the DCDC output voltage is increased to charge the storage battery after the high voltage is increased; and if the storage battery is in the high electric quantity state, adjusting the DCDC output voltage according to the obtained DCDC output current after the high voltage is applied, and charging according to the DCDC output voltage. In the embodiment of the invention, the DCDC output voltage of the storage battery is reasonably adjusted according to the determined state of the storage battery, so that the extra energy loss of the storage battery is reduced and the charging efficiency of the storage battery is improved while low-voltage charging and distribution of the vehicle are protected.

    本发明实施例提供了一种车辆充配电方法、装置、存储介质和整车控制器。该方法包括:在上高压前获取输入低压系统电压,并确定出蓄电池状态;若蓄电池处于馈电状态,则在上高压后提高DCDC输出电压给蓄电池充电;若蓄电池处于高电量状态,则在上高压后根据获取的DCDC输出电流调整DCDC输出电压,并根据DCDC输出电压进行充电。本发明实施例中,根据确定出的蓄电池状态,合理地调整蓄电池的DCDC输出电压,在保护车辆低压充配电的同时,降低蓄电池额外的能量损耗,提升蓄电池的充电效率。
