CHARGING CONTROL APPARATUS FOR POWER STORAGE DEVICE AND METHOD FOR CONTROLLING CHARGING OF POWER STORAGE DEVICE
First Claim
1. A charging control apparatus for a power storage device mounted on an electric powered vehicle, comprising:
- a condition setting unit for setting charge allowable power based on a state of said power storage device; and
a drive control unit for stopping electric power supply from an external power supply of said electric powered vehicle and driving a vehicle-mounted electric load by electric power supplied from said power storage device, if said charge allowable power is smaller than or equal to a prescribed electric power margin when said vehicle-mounted electric load is operated in an external charging mode in which said power storage device is charged by said external power supply.

Abstract
In an external charging mode of a plug-in hybrid vehicle, electric power from an external power supply electrically connected to a connector is converted and supplied to a power line electrically connected to a battery and an electric air-conditioning device. If charge allowable power of the battery is smaller than or equal to a prescribed value when the electric air-conditioning device is operated, a DFR is opened to stop electric power supply from the external power supply and drive the electric air-conditioning device by electric power of the battery. As a result, even if the consumed power of the electric air-conditioning device is suddenly decreased, the inflow of surplus electric power that cannot be absorbed by the battery from the external power supply can be prevented.
