The invention relates to a charging control method and system of an electric vehicle and a computer readable medium. The charging control method comprises the steps that S1, the current voltage value of an electric vehicle battery and the minimum charging voltage value of a charging pile are obtained; s2, whether the current voltage value of the electric vehicle battery is smaller than the minimum charging voltage value or not is judged, if yes, a virtual voltage value is sent to the charging pile, the charging mode is set to be a step-down charging mode, charging of the electric vehicle battery is controlled according to the step-down charging mode, and the virtual voltage value is larger than or equal to the minimum charging voltage value; and S3, in the charging process, whether the current voltage value of the electric vehicle battery is larger than or equal to the minimum charging voltage value or not is judged, if yes, the charging mode is set to be a normal charging mode, and charging of the electric vehicle battery is controlled according to the normal charging mode. The charging efficiency of the electric vehicle battery can be improved, and the vehicle using experience of a user is improved.

    本发明涉及一种电动车的充电控制方法、系统及计算机可读介质。该充电控制方法包括:步骤S1:获得电动车电池的当前电压值和充电桩的最低充电电压值;步骤S2:判断电动车电池的当前电压值是否小于最低充电电压值,若判断为是,则向充电桩发送虚拟电压值,并且设置充电模式为降压充电模式,根据降压充电模式控制电动车电池充电,其中,虚拟电压值大于等于最低充电电压值;步骤S3:在充电过程中,判断电动车电池的当前电压值是否大于等于最低充电电压值,若判断为是,则设置充电模式为正常充电模式,根据正常充电模式控制电动车电池充电。本发明可以提高电动车电池的充电效率并提升用户的用车体验。
