ABSTRACT:
A charger is operable in a normal mode such that output power matches a provided electric power command value CHPW, and limits the output power to a limit value PS in a saving mode if the electric power command value CHPW exceeds the limit value PS. A charging ECU performs feedback-control for compensating for the electric power command value CHPW such that a charging power monitor value PM sensed by a charging power sensing unit matches a target value PR, and in addition, limits an increase in the electric power command value CHPW such that the electric power command value CHPW does not significantly deviate from the target value PR. As a result, in a vehicle charging system on which an add-on charger having a power saving function is mounted, stabilization of the behavior when the add-on charger returns from a saving operation to a normal operation is allowed.
