The invention relates to a temperature control method and device for a vehicle power battery, a vehicle and a storage medium, and the method comprises the steps: calculating the time for heating the vehicle power battery from the current temperature to a target charging temperature when the current temperature of the vehicle power battery is lower than a preset temperature, and obtaining a target heating duration; determining a target charging station from historical charging station information of a pre-constructed user charging database according to the current vehicle information, and calculating the predicted time length and predicted electricity consumption of the vehicle from the current position to the target charging station; and on the basis of the target heating duration, the current time point, the historical charging behavior data, the predicted duration and the predicted electricity consumption, judging that the current time point meets a time point for starting battery heating, generating battery heating reminding information, and sending the battery heating reminding information to a user terminal corresponding to the vehicle. The user is reminded to start the battery heating function in time, and the charging efficiency of the vehicle under the low-temperature condition is improved.

    本申请涉及一种车辆动力电池的温度控制方法、装置、车辆及存储介质,其中方法包括:当车辆动力电池的当前温度低于预设温度时,计算车辆动力电池从当前温度加热到目标充电温度的时间,得到目标加热时长;根据当前车辆信息从预先构建的用户充电数据库的历史充电站信息中确定目标充电站,计算车辆从当前位置到目标充电站的预测时长和预测用电量;基于目标加热时长、当前时间点、历史充电行为数据、预测时长和预测用电量判断当前时间点满足开启电池加热的时间点,生成电池加热提醒信息,并将电池加热提醒信息发送到与车辆对应的用户终端。本申请及时提醒用户开启电池加热功能,提高低温情况下车辆的充电效率。
