Abstract: A battery charging control method and apparatus is disclosed. The battery charging control method includes inputting a preset magnitude of a current to a battery during a preset period of time, identifying a diffusion characteristic of a material in the battery, and determining whether to change the magnitude of the current to be input to the battery based on the identified diffusion characteristic of the material, in which the diffusion characteristic may be determined based on a distribution of the material in one or more of a cathode of the battery, an anode of the battery, and an electrolyte of the battery in response to the input of the current in the battery.
