The invention provides a battery heating control method and device, a storage medium and equipment.The method comprises the steps that when a vehicle is located on an expressway and a battery needs to be heated, the distance and duration, namely the expressway remaining mileage and the expressway remaining time, of the vehicle driving to an expressway exit along a navigation route with the current position as a starting point are obtained, and then the distance and duration of the vehicle driving to the expressway exit along the navigation route are obtained; according to the high-speed remaining mileage and the high-speed remaining time, whether the spontaneous heating amount of the battery meets the battery tail end heating requirement or not is judged, if yes, a target temperature threshold value is determined according to the high-speed remaining time, the battery heating stopping temperature is controlled based on the difference value obtained by subtracting the target temperature threshold value from the battery heating target temperature, and if not, the battery heating stopping temperature is controlled. And if so, controlling the temperature when the battery stops heating based on the battery heating target temperature. Therefore, when the spontaneous heating amount of the battery can meet the battery tail end heating requirement, the battery tail end is heated by utilizing the spontaneous heating amount of the battery, so that the energy consumption is effectively reduced, and the endurance mileage is improved.

    本申请提供一种电池加热控制方法、装置、存储介质及设备,该方法中,当车辆处于高速道路上,且电池存在加热需求时,获取以当前位置为出发点,沿导航路线行驶至高速出口的距离和时长,即高速剩余里程和高速剩余时间,之后,根据高速剩余里程和高速剩余时间判断电池的自发热量是否满足电池末端加热需求,若满足,则根据高速剩余时间确定目标温度阈值,基于电池加热目标温度减去目标温度阈值得到的差值控制电池停止加热时的温度,若不满足,则基于电池加热目标温度控制电池停止加热时的温度。如此,当电池的自发热量能够满足电池末端加热需求时,实现利用电池自发热进行电池末端加热,从而有效节省能耗,提高续航里程。
