The invention relates to a battery heat preservation method and device, an automobile and a storage medium, and the battery heat preservation method comprises the steps that under the condition that it is detected that a battery heating function is started, the heating mode of a battery is determined on the basis of at least one of obtained first information, the current battery electric quantity, the estimated remaining battery electric quantity and second information; wherein the heating mode is a charging heating mode or a self-heating mode, the first information represents whether a charging gun is inserted into a charging port of the automobile or not, the remaining battery electric quantity refers to the remaining battery electric quantity assumed in advance after a battery is heated for the first time through the current battery electric quantity, and the second information represents whether a charging station where the automobile can go to exists or not; the first time is obtained based on the current environment temperature, the lowest environment temperature in the future time period, the current battery temperature prediction and the target battery temperature; and determining the heating cost corresponding to the heating mode, and outputting the heating mode and the heating cost.
本发明涉及一种电池保温方法及装置、汽车、存储介质,电池保温方法包括:在检测到电池加热功能启动的情况下,基于获得第一信息、当前电池电量、预估的剩余电池电量和第二信息中的至少一种,确定电池的加热方式;其中,加热方式为充电加热方式或者自加热方式,第一信息表征汽车的充电口是否插入充电枪,剩余电池电量是指预先假设利用当前电池电量对电池加热第一时间后剩余的电池电量,第二信息表征是否存在汽车能够前往的充电站,第一时间是基于当前环境温度、未来时段内环境的最低温度、当前电池温度预测和目标电池温度得到;确定加热方式对应的加热成本,并输出加热方式和加热成本。
