Problems solved by technology
For example: at zero temperature, the charging capacity of the battery will decrease with the decrease of temperature, so there is a technical problem of low charging efficiency in low temperature environment
[0003] In order to solve the problem of low charging efficiency in low temperature environment, in related technologies, a battery heating function is proposed to perform the battery charging function after raising the battery temperature
However, the current battery heating function and battery charging function are realized in time-sharing.

Description
technical field [0001] The present application relates to the field of vehicles, in particular, to a battery energy processing device, method and vehicle. Background technique [0002] With the widespread use of new energy sources, batteries can be used as power sources in various fields. Depending on the environment in which the battery is used as a power source, the performance of the battery will also be affected. For example: at zero temperature, the charging capacity of the battery will decrease as the temperature decreases, so there is a technical problem of low charging efficiency in a low temperature environment. [0003] In order to solve the problem of low charging efficiency in a low temperature environment, in the related art, a battery heating function is proposed to perform a battery charging function after raising the battery temperature. However, the current battery heating function and battery charging function are realized in time-sharing. For this reaso...
