A method for charging a battery, includes: detecting current geographic location information and current time information of the terminal; determining a current temperature characteristic of an environment where the terminal is currently located according to the current geographic location information and the current time information; determining a target full charging voltage matching the current temperature characteristic, and charging a battery of the terminal with the target full charging voltage, in which different full charging voltages match with different temperature characteristics.

Method for charging a battery and terminal

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.

Battery module, charging control method, and storage medium

A prediction method of battery health includes: obtaining an environment temperature, and a discharge capacity and an operating parameter of a battery; determining an estimated operating parameter in a preset temperature at the discharge capacity according to the environment temperature, the discharge capacity and the operating parameter; determining an estimated capacity of the battery according to the estimated operating parameter; and determining a health level of the battery according to the estimated capacity of the battery and a reference capacity, at the discharge capacity of the battery.
