VEHICLE CHARGING SYSTEM
First Claim
1. A vehicle charging system for charging a vehicle-mounted power storage device, comprising:
- a charger configured to be supplied with electric power from a power supply external to a vehicle for charging said power storage device, and operable in a normal mode such that output power matches a provided electric power command value, and limiting the output power to a limit value in a saving mode if said electric power command value exceeds said limit value;
a charging power sensing unit for sensing charging power supplied to said power storage device; and
a charging control device for generating said electric power command value and outputting said electric power command value to said charger,said charging control device performing feedback-control for compensating for said electric power command value based on the charging power sensed by said charging power sensing unit, such that the charging power sensed by said charging power sensing unit matches a target value, and in addition, limiting an increase in said electric power command value such that said electric power command value does not significantly deviate from said target value.

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.
