The invention provides a battery preheating method and device of a vehicle, the vehicle and a storage medium, and relates to the technical field of new energy vehicles. Determining whether the temperature of a battery of the vehicle is lower than a set temperature threshold value or not when the vehicle is not started and at the awakening moment; when the temperature of a battery of the vehicle is lower than a set temperature threshold value, the environment temperature is collected; the vehicle determines the heating duration of a battery of the vehicle according to the environment temperature; the vehicle determines whether a first duration from a preset starting moment of the vehicle to a moment after the current moment is superposed with the heating duration is smaller than a set second duration or not; and when the first duration of the vehicle is smaller than a set second duration, the heating duration of the battery of the vehicle is preheated. After the battery is heated, when a user uses the vehicle at the subsequent starting moment, the battery is not cooled, the high-load function (such as heavy-load climbing) can be achieved, the charging efficiency of the battery is also high, and the reliability of heating the battery is also high.
本申请提供的一种车辆的电池预加热方法、装置、车辆及存储介质,涉及新能源汽车技术领域。车辆在未启动且处于唤醒时刻时,确定车辆的电池的温度是否低于设定的温度阈值;车辆在车辆的电池的温度低于设定的温度阈值时,采集环境温度;车辆根据环境温度,确定对车辆的电池的加热时长;车辆确定当前时刻叠加上加热时长后的时刻,距离预设的车辆的启动时刻的第一时长是否小于设定的第二时长;车辆在第一时长小于设定的第二时长时,对车辆的电池预加热加热时长。对电池加热后,用户在后续地启动时刻使用车辆时,电池尚未冷却,可以实现高负荷的功能(例如,重载爬坡),电池的充电效率也高,可见,上述对电池加热的可靠性也高。
