The invention relates to the technical field of battery heat management control, in particular to a power battery driving heating control method and device, a storage medium and a vehicle. The control method comprises the steps that when the vehicle is in a drivable state and a power battery has a heating requirement, if the vehicle is not in a navigation state, power battery driving heating is started; if the vehicle is in the navigation state, determining the average discharge power of a preset time period after the current moment according to the navigation information, the average energy consumption of the vehicle and the SOC and the lowest cell temperature of the power battery at the current moment, and determining the vehicle demand power of the preset time period after the current moment according to the navigation information; and if the average discharge power is lower than the vehicle demand power, starting power battery driving heating, otherwise, not starting the power battery driving heating. The driving heating starting time of the power battery can be accurately controlled in combination with navigation information, the driving heating time of the battery is shortened, the power consumption of the whole vehicle is reduced, and the endurance mileage of the electric vehicle is prolonged.
本发明涉及电池热管理控制技术领域,具体涉及一种动力电池行车加热控制方法、装置、存储介质和车辆,所述控制方法包括:响应于车辆处于可行驶状态且动力电池存在加热需求时,若车辆未处于导航状态,开启动力电池行车加热;若车辆处于导航状态,根据导航信息、车辆平均能耗以及动力电池当前时刻的SOC和最低电芯温度确定当前时刻之后的预设时间段的平均放电功率,根据导航信息确定当前时刻之后的预设时间段的车辆需求功率;若平均放电功率低于车辆需求功率,开启动力电池行车加热,反之不开启动力电池行车加热。其能够结合导航信息精准控制动力电池行车加热开启时机,减少电池行车加热时间,降低整车功耗,延长电动汽车续航里程。
