The invention relates to the technical field of new energy vehicles, in particular to a battery heating method and device, a vehicle and a storage medium. The method comprises the steps that the current temperature of each single battery cell in a power battery pack is collected, if the current temperature is within a preset temperature interval, a vehicle control unit is awakened, a high-voltage power-on request is sent to the vehicle control unit, and if a high-voltage power-on instruction fed back by the vehicle control unit based on the high-voltage power-on request is received, high-voltage power-on is carried out, and a heating request is sent to the heat management system, so that the power battery pack is heated through the heat management system. Therefore, the problem that heat preservation of the vehicle battery cannot be monitored in real time at the present stage is solved, and when a user does not use the vehicle, the battery manager can regularly inspect the temperature of the battery, judge the requirement of low-temperature heat preservation and heating and automatically heat the power battery; therefore, the temperature of the power battery can still meet the starting requirement when a user uses a vehicle, and the user experience is improved.

    本发明涉及新能源汽车技术领域,具体涉及一种电池加热方法、装置、车辆及存储介质。其中,方法包括:采集动力电池组中每个单体电芯的当前温度,若当前温度处于预设温度区间,则唤醒整车控制器,并发送高压上电请求至整车控制器,若接收到整车控制器基于高压上电请求反馈的高压上电指令,则进行高压上电,并发送加热请求至热管理系统,以通过热管理系统对动力电池组进行加热。由此,解决了现阶段无法对车辆电池保温需要进行实时监控的问题,在用户未使用车辆的阶段,电池管理器会定时巡检电池温度,进行低温保温加热的需求判断,自动对动力电池进行加热动作,以便用户在用车时动力电池温度仍可满足启动的需求,提升用户体验。
