Abstract:
1. An electric charging system in which an electric charger and an electric vehicle are connected by a charging cable, and an electric storage device installed in the electric vehicle is charged, the electric charging system comprising: a first reference setting unit for setting a reference point on the basis of a variation rate of supply-side processing data, the reference point being set with respect to the supply-side processing data that are calculated by subjecting a supplied voltage, a supplied current, or a supplied power at the electric charger side to a predetermined filter processing; a second reference setting unit for setting a reference point on the basis of a variation rate of reception-side processing data, the reference point being set with respect to the reception-side processing data that are calculated by subjecting a received voltage, a received current, or a received power at the electric vehicle side to a predetermined filter processing; a data synchronization unit for synchronizing the supply-side processing data and the reception-side processing data on the basis of the reference points of the supply-side processing data and the reception-side processing data; and a determination unit for comparing the synchronized supply-side processing data and reception-side processing data and determining whether or not a power supply state between the electric charger and the electric vehicle is normal.
