The invention discloses an electric vehicle lithium battery temperature control method. The method comprises the steps of obtaining a lithium battery temperature control request; detecting the environment temperature state of the electric vehicle, the current characteristics of the lithium battery and the state of the electric vehicle after the temperature control request is obtained; and judging and controlling the whole vehicle to enter one of three different lithium battery temperature control modes based on the environment temperature state of the electric vehicle, the current characteristics of the lithium battery and the state of the electric vehicle, and performing temperature control on the lithium battery of the electric vehicle. The invention further discloses a corresponding control method, electronic equipment and a computer readable storage medium. According to the invention, the battery characteristic can be kept in an optimal state and the battery capacity is saved when the vehicle is driven and parked in different environments; the optimal temperature state of the battery during driving is achieved, the service life of the battery is prolonged, and the endurance mileage is increased; meanwhile, the heat preservation and refrigeration functions can be reasonably started according to the use requirements of users, the waiting time of a driver for starting the vehicle is shortened, and the use perceptibility and driving experience of customers are enhanced.

    本发明公开了一种电动车辆锂电池温度控制方法,包括:获取锂电池温度控制请求;基于获取温度控制请求后检测电动车辆的环境温度状态、锂电池当前特性以及电动车辆状态;基于电动车辆的环境温度状态、锂电池当前特性及电动车辆状态判断并控制整车进入三种不同锂电池温度控制模式中的一种,对电动车辆锂电池进行温度控制。还公开对应控制方法,电子设备及计算机可读存储介质。本发明实现不同环境下行驶和停放使用时,电池特性能保持在最优状态下且节省电池容量;既达到行车时电池最佳温度状态,延长电池寿命,提高续航里程;同时也可以根据用户的使用需求,合理的开启保温和制冷功能,缩短驾驶员启动车辆的等待时间,增强客户使用感知度和驾驶体验。
