The invention relates to the technical field of electric automobiles, and discloses a charging control method, a charging control device and an electric automobile. The method comprises the steps that the maximum output voltage value and the actual output voltage value of a charging pile are acquired; acquiring a total rated voltage value and a current voltage value of a power battery of the vehicle; when the total rated voltage value of the power battery is greater than the maximum output voltage value of the charging pile, the current voltage value of the power battery is compared with the actual output voltage value of the charging pile, so that a direct charging loop or a boost charging loop is controlled to be conducted; and the charging pile charges the power battery through the selected loop. According to the charging control method, the electric vehicle and the charging system, charging piles with different output voltage values can be compatible for charging, and the charging efficiency is improved.

    本发明涉及电动汽车技术领域,公开了一种充电控制方法、充电控制装置及电动汽车,所述方法包括获取充电桩的最大输出电压值与实际输出电压值;获取车辆的动力电池的总额定电压值与当前电压值;当所述动力电池的总额定电压值大于所述充电桩的最大输出电压值,通过比较所述动力电池的当前电压值与所述充电桩的实际输出电压值的大小,从而选择控制直充回路还是升压充电回路导通,以使所述充电桩通过所选择的回路为所述动力电池充电。本发明提供的一种充电控制方法、电动汽车及充电系统,可兼容不同输出电压值的充电桩进行充电,并提高充电效率。
