Patent abstract
In an electric charging system, an electric charger and an electric vehicle is connected via a charging cable, and charging power is provided to a battery of the electric vehicle via the charging cable. The electric charger calculates a voltage drop based on a supply current Is of the electric charger and an electric resistance of the charging cable. The electric charger compares a supply voltage of the electric charger with a determination value, and, if the supply voltage reaches the determination value, determines that the battery is charged to a fully-charged state. The determination value is updated by adding the voltage drop to a preset determination base value so as to take the voltage drop of the charging cable into account.
