The invention provides an electric vehicle charging control method. According to the technical scheme, after charging is started, the temperature of the battery pack is collected according to a certain time interval, power is distributed according to the real-time temperature, and when the real-time temperature is larger than or smaller than a threshold value, a certain power is distributed from licensed power provided for the electric vehicle by a charging device to be used for a heat management system to refrigerate or heat the battery pack. According to the technical scheme, the method is simple in logic, convenient to use, efficient and energy-saving, reasonable and dynamic allocation of heating and cooling power and charging power is achieved for the output power of the charging device such as the charging pile, the remaining charging duration can be predicted according to the charging power, the charging energy efficiency is guaranteed, and therefore the charging process of the electric vehicle is safer, more efficient and more stable, and the charging efficiency is improved. And the method is more friendly to users. The technical scheme is generally suitable for direct current charging piles and alternating current charging piles of various current power gears.

    本发明提供一种电动汽车充电控制方法。本发明技术方案为启动充电后按照一定的时间间隔采集电池包的温度,根据实时温度分配功率,当实时温度大于或小于阈值时,从充电装置提供给电动汽车的许可功率中,分配一定功率用于热管理系统以为电池包提供制冷或加热。本发明技术方案逻辑简单、使用方便、高效节能,针对充电桩等充电装置的可输出功率,实现制热制冷功率和充电功率的合理动态调配,且能根据充电功率预测剩余充电时长,并保证充电能效,故使电动汽车充电过程更加安全、高效、稳定,对用户更为友好。该技术方案普遍适用于当前各种功率档位的直流充电桩和交流充电桩。
