BATTERY CHARGING CONTROL METHOD AND DEVICE

This application provides a battery charging control method and device. Voltages of N cells in an Mth sampling period are obtained, and a voltage of the battery at each sampling moment among K sampling moments in said sampling period is calculated. Charging of the battery is stopped when the voltage of the battery increases monotonically in the Mth sampling period and a trend of a fitting curve of the voltage of at least one cell among the N cells in said sampling period is not rising.
