The invention discloses a vehicle battery charging method, a vehicle battery charging device, a vehicle control unit and a computer readable storage medium, and the method comprises the steps: obtaining the charging time required for reaching the target electric quantity according to the remaining electric quantity of a vehicle and the parameters of a charging pile; then calculating the total time length corresponding to the starting time meeting the charging starting condition to the charging ending time set by the user, and under the condition that the total time length is greater than the charging time length, sorting all time periods within the time interval from the starting time meeting the charging starting condition to the charging ending time set by the user according to the electricity price; according to the charging method and device, the multiple time periods corresponding to the sequence of the electricity prices from low to high are selected as the charging time, then the charging request signal is sent based on the determined charging time, the charging pile is controlled to execute the charging operation on the vehicle battery, the charging cost is saved for the user to the maximum extent while the charging requirement of the user is met, and the charging cost of the user is reduced.

    本申请揭示一种车辆电池充电方法、车辆电池充电装置、整车控制器及计算机可读存储介质,该方案首先根据车辆的剩余电量和充电桩参数,获得达到目标电量所需的充电时长,然后计算满足充电开启条件的起始时间到用户设置的充电结束时间对应的总时长,在总时长大于充电时长的情况下,根据电价高低对位于满足充电开启条件的起始时间到用户设置的充电结束时间的时间区间内的各个时段进行排序,选择电价由低到高排序所对应的若干个时段作为充电时间,再基于确定的充电时间发送充电请求信号,控制充电桩对车辆电池执行充电操作,实现了在满足用户充电需求的同时,最大化为用户节省充电费用,降低了用户充电成本。
