The embodiment of the invention discloses a quick charging method and device for an electric vehicle, electronic equipment and a storage medium. The method comprises the steps of obtaining historical test data after receiving a charging instruction, sequentially constructing a current-capacity hyperbolic complex diagram and a current-temperature hyperbolic complex diagram through a first test data set and a second test data set, and respectively determining a sudden change intersection point capacity value and a sudden change intersection point temperature value, meanwhile, the charging state of the target battery is continuously monitored, each real-time charging parameter is compared with the abrupt change intersection point capacity value and the abrupt change intersection point temperature value, and finally the charging mode of the target battery in the current charging stage is determined based on the comparison result. Through switching between the interval charging mode and the linear charging mode, the target battery keeps the high-level battery charging current in the whole charging process, the charging time of the target battery is shortened, the purpose of rapidly charging the electric automobile is achieved, and the use satisfaction degree of a user is improved.

    本说明书实施例公开了一种电动汽车快速充电方法、装置、电子设备及存储介质。该方法包括通过接收充电指令后,获取历史测试数据,通过第一测试数据组和第二测试数据组依次构建电流‑容量双曲线复合图和电流‑温度双曲线复合图,分别确定突变交点容量值和突变交点温度值,同时持续监测目标电池的充电状态,将各实时充电参数分别与突变交点容量值和突变交点温度值进行比对,最后基于比对结果确定目标电池在当前充电阶段的充电模式,通过区间充电模式和线性充电模式的切换使得目标电池在整个充电过程中都保持高位电池充电电流,减少了目标电池的充电时间,达到了电动汽车快速充电的目的,提升了用户的使用满意度。
