Abstract
A charging system is provided with a secondary battery, a charging current supplier for supplying a charging current to the secondary battery, an internal resistance detector for detecting the resistance value of the internal resistance of the secondary battery, and a charge controller for increasing the charging current to be supplied to the secondary battery by the charging current supplier as the resistance value detected by the internal resistance detector decreases.
