Abstract
Battery heating systems and methods are provided in the present disclosure. A battery heating system includes: a temperature sampling module configured to collect a target sampling temperature; a first switch configured to be turned on or off based on a driving signal; a control module configured to determine, based on the target sampling temperature and a correspondence between the target sampling temperature and the driving signal, a duration where the first switch is controlled to be turned on and a duration where the first switch is controlled to be turned off, and generate the driving signal; and a heating module configured to heat the battery module set using an output power of the battery module set when the first switch is turned on, and stop heating the battery module set when the first switch is turned off. As a result, fineness of battery heating can be improved.
