A charging control system for a battery includes a temperature sensor, a voltage sensor, a pressure sensor, and a controller. The controller is configured to determine a threshold pressure change associated with a full charge of the battery based on map data selected from a predetermined data map associated with the battery, monitor a present voltage value obtained by the voltage sensing means and a total pressure change based on a present pressure value obtained by the pressure sensing means, continue the charging process when the present voltage value exceeds an upper limit voltage value, and total pressure change is less than threshold pressure change, and terminate the charging process when the present voltage value exceeds the upper limit voltage value, and the total pressure change is greater than or equal to the threshold pressure change.
