Vehicle and method of charging vehicle
First Claim
1. A vehicle having a power storage mechanism that stores electric power supplied from an external power supply through a coupling unit that outputs a signal indicating a value of a current which can be supplied, said vehicle comprising:
- a charger configured to be connected to said coupling unit and to supply a current to said power storage mechanism; and
a control unit configured to control the charger and;
calculate a first charging current value in accordance with a state of said power storage mechanism,calculate a second charging current value in accordance with the value of the current which can be supplied by said coupling unit,calculate a third charging current value by setting a smaller one of said first charging current value and said second charging current value as said third charging current value;
set the current to be supplied by the charger to said power storage mechanism equal to the third charging current value; and
correct the third charging current value during charging based on said first charging current value and said second charging current value.

Abstract
An electronic Control Unit (ECU) executes a program including a step of calculating a first charging current value in accordance with the state of a battery pack; a step of calculating a second charging current value in accordance with the current capacity of a charging cable coupling a hybrid vehicle and an external power supply to output a pilot signal CPLT indicating the current capacity; a step of setting the smaller one of the first charging current value and the second charging current value as a third charging current value; and a step of controlling a charger such that the output current value of the charger connected to the charging cable for controlling a value of a current supplied to the battery pack is equal to the third charging current value, for charging the battery pack.
