Abstract
There is provided an electric charging system in which an electric charger and an electric vehicle are connected by a charging cable. The electric charger calculates a voltage drop amount in the charging cable on the basis of a supplied current at the electric charger side and an electric resistance of the charging cable. The electric charger also compares a determination voltage with a supplied voltage at the electric charger side and determines that a battery has been charged to a fully charged state when the supplied voltage reaches the determination voltage. The determination voltage used for such full charge determination is updated by adding the voltage drop amount to a basic determination voltage that is set in advance.
