Charging apparatus for vehicle and method for charging vehicle
First Claim
1. A charging apparatus for a vehicle by which a vehicle-mounted power storage device for driving the vehicle is charged from a power supply external to the vehicle, comprising:
- a detecting unit for detecting electric power that can be supplied from said power supply to said vehicle, said detecting unit includesa voltage detecting unit for detecting the voltage of said power supply, anda rated current detecting unit for detecting a rated value of a current that can be received from said power supply;
a charging execution unit for receiving the electric power supplied from said power supply and executing charging of said power storage device, in accordance with a provided command; and
a control unit for determining whether or not a suppliable electric power detected by said detecting unit is included in a predefined standard, and controlling said charging execution unit based on a result of determination,said control unitcontrolling said charging execution unit to execute charging in accordance with the suppliable electric power, when said control unit determines that said suppliable electric power is included in said predefined standard,controlling said charging execution unit to execute charging by limiting a charging current to a predefined value, when said control unit determines that said suppliable electric power is not included in said predefined standard and when said control unit determines that said power supply is normal based on a voltage of said power supply detected by said detecting unit, said predefined value being a minimal rated current value included in said predefined standard, andprohibiting charging, when said control unit determines that said suppliable electric power is not included in said predefined standard and when said control unit determines that said power supply is abnormal,wherein said control unit determines whether or not said suppliable electric power is included in said predefined standard, based on whether or not a combination of the voltage detected by said voltage detecting unit and a rated current detected by said rated current detecting unit matches at least one predefined combination.

Abstract
An ECU detects a rated current that can be supplied from a power supply to a power storage device, based on a pilot signal. If a combination of detected values of a voltage, the rated current and a power supply frequency matches a predefined combination, the ECU executes charging with a voltage, a current and a frequency in accordance with the combination. On the other hand, if it is determined that the combination of the voltage, the rated current and the frequency does not match any one of predefined combinations and if it is determined that the power supply itself is normal, the ECU executes charging by limiting a charging current to a predefined minimum rated current value. If it is determined that the combination of the voltage, the rated current and the frequency does not match any one of predefined combinations and if it is determined that the power supply is abnormal, the ECU prohibits charging.
