Classification: CPC H  Y | IPC H

Claim 0:
1. A battery module, comprising:
a plurality of cells;
a series-parallel conversion circuit; and
a controller,
wherein the controller is coupled to the series-parallel conversion circuit and is configured to control the series-parallel conversion circuit to convert a connection mode of cells in the plurality of cells when the battery module is to be charged, such that the plurality of cells form a charging architecture state with a charging current greater than a preset current value, the charging architecture state comprising at least one of: at least two cells coupled in series, at least two cells coupled in parallel, a combination of first cells coupled in series and second cells coupled in parallel, or a single cell;
wherein the controller is configured to obtain a charging current of the plurality of cells during a charging process, and in response to the charging current being less than the preset current value, to control the series-parallel conversion circuit to convert the charging architecture state formed by the plurality of cells, such that a charging current of a charging cable is restored to a current between the preset current value and a maximum current that the charging cable can carry.
