The invention discloses a battery charging preheating method and device, a vehicle, electronic equipment and a storage medium, and the method comprises the steps: obtaining the current battery state information and the current environment temperature of a vehicle battery after the charging intention information of the vehicle is determined through responding to a charging instruction; inputting the current battery state information and the current environment temperature into a simulation model of the target preheating temperature to obtain the target preheating temperature of the battery; inputting the real-time driving parameters and the historical driving information of the vehicle into the simulation model of the target preheating temperature so as to obtain the target required duration for heating to the target preheating temperature; according to the duration required for heating to the target preheating temperature, the starting moment of battery preheating is determined; and when the starting time of battery preheating is reached, controlling the battery to be preheated to the target preheating temperature. According to the method, battery preheating can be dynamically adjusted, the energy consumption reaches the minimum, meanwhile, the battery temperature is in the optimal charging interval when the electric vehicle arrives at the pile, it is ensured that the vehicle does not lose too much endurance mileage, and the charging performance of the battery is improved.

    本公开公开了电池充电预热方法及装置、车辆、电子设备和存储介质,在通过响应充电指令确定车辆的充电意图信息后,获取车辆电池的当前电池状态信息及当前环境温度;将当前电池状态信息及当前环境温度输入目标预热温度的仿真模型,以获取电池的目标预热温度;将车辆实时行驶参数及历史行驶信息输入目标预热温度的仿真模型,以获取加热至目标预热温度的目标所需时长;根据加热至目标预热温度的所需时长,确定电池预热的开启时刻;在到达电池预热的开启时刻时,控制电池预热至目标预热温度。本公开可实现动态调节电池预热,使能耗达到最低的同时实现电车到桩时电池温度处在最佳充电区间,确保车辆不会失去过多的续航里程,提高电池的充电性能。
