BATTERY MODULE, CHARGING CONTROL METHOD, AND STORAGE MEDIUM

A battery module includes: a battery module including 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 including 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.
