Abstract
A controller in a charging control system controls a charger to heat a battery at a low temperature by pulse charging and discharging up to a desired temperature and then moves to a normal charging mode. The controller calculates an ion concentration of an active material at electrode portions of the battery on the basis of the temperature data and the electric current data obtained, switch the pulse charging and discharging between a charging mode and a discharging mode on the basis of a pulse width when the ion concentration reaches a threshold.
