The invention provides a power battery heat preservation control method and device and a storage medium, and relates to the field of new energy vehicles. According to the method, the state information of the electric vehicle is obtained, whether correction operation is executed on the current heat preservation target temperature or not is judged, if it is determined that the correction operation is executed, power information of the electric vehicle is obtained, the power information comprises engine starting information or torque limiting strategy activation information, and the current heat preservation target temperature is corrected according to the power information. According to the method, the new heat preservation target temperature is obtained, the new heat preservation target temperature is used for judging whether the gun insertion heat preservation operation is executed or not during next gun insertion charging, self-adaptive adjustment of the heat preservation target temperature is achieved, and therefore the requirement for different battery cell temperatures can be met for different environments, unnecessary energy consumption is avoided, and the use cost of a user is reduced.

    本申请提供一种动力电池保温控制方法、设备及存储介质,涉及新能源车辆领域。该方法通过获取电动车辆的状态信息,判断是否对当前保温目标温度执行修正操作,若确定执行修正操作,则获取电动车辆的动力信息,动力信息包括发动机启动信息或者限扭策略激活信息,根据动力信息对当前保温目标温度进行修正,得到新的保温目标温度,新的保温目标温度用于在下一次插枪充电时,判断是否执行插枪保温操作,实现了对保温目标温度的自适应调整,从而能够针对不同环境,满足电池电芯温度不同的需求,避免造成不必要的能耗,降低了用户使用成本。
