Abstract

The embodiment of the invention discloses a battery heating method, device and equipment and a computer readable storage medium, and the method comprises the steps: charging a first energy storage container through employing an external power supply, a battery pack and a second energy storage container if the temperature of the battery pack is detected to be smaller than a first temperature threshold value; adopting the external power supply, the first energy storage container and the second energy storage container to charge the battery pack; and repeating the charging step of the first energy storage container and the charging step of the battery pack until the temperature of the battery pack is larger than or equal to a second temperature threshold value, wherein the second temperature threshold value is larger than the first temperature threshold value. According to the embodiment of the invention, the external power supply is repeatedly adopted to charge the battery pack and the battery pack is adopted to discharge the energy storage container, so that the temperature of the battery pack can be increased, and the problems that the charging and discharging performance of the battery is reduced and the service life of the battery is shortened due to the fact that the battery is continuously charged when the temperature of the battery is relatively low are avoided.

Description

technical field [0001] The present application relates to the field of battery heating, in particular to a battery heating method, device, equipment and computer-readable storage medium. Background technique [0002] Since the main energy source of electric vehicles is electric energy, which will not cause environmental pollution, it can effectively solve the problems of vehicle exhaust pollution and oil energy shortage, which has become the current development trend of the automobile industry. As the energy source of electric vehicles, batteries need to be Provide corresponding energy to electric vehicles within a reasonable temperature range. In practice, it is found that when the temperature of the battery is low, if the battery is charged, the charging and discharging performance of the battery will be reduced, and the service life of the battery will be reduced. Therefore, before the battery is charged, how to increase the temperature of the battery is an urgent proble...
