The invention discloses a control method, device and equipment for alternating current charging of an electric vehicle and a medium, and the method comprises the steps: obtaining the working parameters of a charging gun and a charger under the condition that the charging gun is connected with the charger; and the power supply voltage of the power grid and the state parameters of the charged battery are monitored in real time. And determining the maximum power supply current which can be output by the current charger in combination with the real-time power supply voltage and state parameters and the working parameters of the charging gun and the charger. And querying a charging mapping table of the charged battery according to the real-time state parameters, and determining the maximum allowable charging current of the current charged battery. According to the invention, the charging current is adjusted in real time according to the power supply voltage of the power grid, the influence of high-power charging in the peak period of power utilization on the power grid is prevented, the function locking of the charger is avoided, and the charging efficiency of the electric vehicle in the peak period of power utilization is improved.

    本发明公开了一种电动车交流充电的控制方法、装置、设备和介质,该方法中,在充电枪与充电机建立连接的情况下,获取充电枪和充电机的工作参数。对电网的供电电压和被充电池的状态参数进行实时监测。结合实时的供电电压和状态参数,以及充电枪和充电机的工作参数,确定当前充电机能输出的最大供电电流。根据实时的状态参数,查询被充电池的充电映射表,确定当前被充电池的最大允许充电电流。采用最大供电电流与最大允许充电电流中的较小值,为被充电池充电,实现了充电电流根据电网的供电电压的实时调节,防止用电高峰期的大功率充电对电网造成的影响,避免了充电机的功能锁定,提高了用电高峰期对电动车的充电效率。
