BATTERY CHARGING CONTROL METHOD AND DEVICE

This application provides a battery charging control method and device. Voltages of N cell units in an Msampling 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 Msampling period and a trend of a fitting curve of the voltage of at least one cell unit among the N cell units in said sampling period is not rising.
