The invention belongs to the technical field of vehicles, and discloses a battery preheating control method, device and equipment and a storage medium. The current driving condition is determined according to the gradient information, the passenger number information and the navigation information; and the number of electric heating wires is determined according to the current driving working condition and a preset battery preheating control strategy, and the battery is preheated according to the number of the electric heating wires. Whether electric energy can reach a target navigation location or a nearby charging station is estimated by combining the navigation remaining mileage, a real-time gradient signal and the number of passengers, and if switching to the charging station is needed, the number of heating wires needing to be started and a circulating water pump are calculated and controlled by combining charging power and heating wire power in advance; the purpose of controlling the battery pack to achieve the optimal charging temperature in advance is achieved, and the charging rate of the battery pack under the low-temperature working condition is improved.

    本发明属于车辆技术领域,公开了一种电池预热控制方法、装置、设备及存储介质。本发明通过根据坡度信息、乘员数量信息以及导航信息确定当前行驶工况;根据所述当前行驶工况和预设电池预热控制策略确定电热丝数量,以根据所述电热丝数量对电池预热。通过结合导航剩余里程和实时坡度信号及乘员数量估算电能是否够抵达目标导航所在地或附近充电站,若需要切换至充电站,提前结合充电功率和加热丝功率计算和控制需要开启的加热丝数量和循环水泵,以达到控制电池包提前实现最佳充电温度的目的,提高了在低温工况时电池包的充电速率。
