The invention relates to an electric vehicle intelligent charging method and system. The electric vehicle intelligent charging method comprises the steps that an intelligent charging mode is configured for the charging process of the electric vehicle, and the minimum SOC value required by charging, the vehicle using time and the target SOC value when the vehicle using time is up are set; when theelectric vehicle is connected with the charging pile, the current SOC value of the electric vehicle is detected, if the current SOC value is smaller than the minimum SOC value, the charging process isstarted immediately, otherwise, the charging duration is calculated according to the current SOC value and the target SOC value, and the charging start time and the charging end time are determined in combination with the charging duration, the electricity price state and the vehicle using time; therefore, a charging scheme which meets the vehicle using time and the target SOC value and is optimal in price is generated, and then the charging process is executed according to the charging scheme. The electric vehicle intelligent charging system comprises an intelligent user side, a charging execution mechanism, a vehicle machine side and a cloud server. The optimal charging scheme can be determined and executed in combination with various factors, and the user requirements are fully met.

    本发明涉及一种电动汽车智能充电方法和系统。电动汽车智能充电方法为:为电动汽车的充电过程配置智慧充电模式,设置充电所需的最小SOC值、用车时间和用车时间到时的目标SOC值;当电动汽车连接充电桩时,检测电动汽车的当前SOC值,若当前SOC值小于最小SOC值,则立即开始执行充电过程,否则,依据当前SOC值、目标SOC值计算充电时长,并结合充电时长、电价状态和用车时间确定充电开始时间和充电结束时间,从而生成满足用车时间和目标SOC值且价格最优的充电方案,进而按照充电方案执行充电过程。电动汽车智能充电系统包括智能用户端、充电执行机构、车机端和云服务器。发明能够结合多方面因素确定最优的充电方案并执行,充分满足用户需求。
