ELECTRICALLY POWERED VEHICLE AND METHOD FOR CONTROLLING ELECTRICALLY POWERED VEHICLE
First Claim
1. An electrically powered vehicle comprising:
- a rechargeable power storage device;
a motor configured to receive electric power supplied from said power storage device and generate vehicle driving power;
an external charging structure configured to charge said power storage device using a power source external to the vehicle; and
a control device that controls the charging of said power storage device such that a value of state of charge of said power storage device does not exceed an upper limit value of the value of state of charge during the charging of said power storage device by said external charging structure, said upper limit value being defined in association with a fully charged state of said power storage device,said control device being configured to increase said upper limit value in accordance with progression of deterioration of said power storage device,an amount of change for said upper limit value being set to be valuable in accordance with a temperature change of said power storage device.

Abstract
An electrically powered vehicle includes: a rechargeable power storage device; an external charging structure configured to charge the power storage device using a power source external to the vehicle; and a control device that controls the charging of the power storage device such that a value of state of charge of the power storage device does not exceed an upper limit value of the value of state of charge during the charging of the power storage device by the external charging structure, the upper limit value being defined in association with a fully charged state of the power storage device. The control device increases the upper limit value in accordance with progression of deterioration of the power storage device. The control device changes an amount of change for the upper limit value in accordance with a temperature change of the power storage device.
