CHARGING CONTROL APPARATUS FOR ELECTRICALLY POWERED VEHICLE, ELECTRICALLY POWERED VEHICLE, METHOD FOR CHARGING CONTROL FOR ELECTRICALLY POWERED VEHICLE, AND COMPUTER-READABLE RECORDED MEDIUM HAVING PROGRAM RECORDED THEREON FOR COMPUTER TO EXECUTE THE CHARGING CONTROL
First Claim
1. A charging control apparatus for an electrically powered vehicle configured in such a manner that a power storage device mounted on the vehicle is chargeable from a power supply outside the vehicle, said charging control apparatus comprising:
- an energy cost prediction unit for predicting an energy cost for a next travel of the vehicle based on an energy consumption during a travel of the vehicle;
a lifetime prediction unit for predicting a lifetime of said power storage device according to an amount of charge to said power storage device, using a relation between an amount of charge to said power storage device and a lifetime of said power storage device;
a usage cost prediction unit for predicting a cost of using said power storage device according to the amount of charge to said power storage device, based on the lifetime of said power storage device predicted by said lifetime prediction unit;
an information unit for informing a user of said energy cost and the cost of using said power storage device in association with the amount of charge to said power storage device; and
a charge command generation unit for generating a command to charge said power storage device from said power supply in accordance with an instruction from said user.

Abstract
An energy cost prediction unit predicts an energy cost for the next travel. A lifetime prediction unit uses a charge amount—lifetime map to predict the lifetime of a power storage device according to an amount of charge to the power storage device. A usage cost prediction unit predicts the cost of using the power storage device according to the amount of charge to the power storage device, based on the lifetime of the power storage device predicted by the lifetime prediction unit. The predicted cost associated with the amount of charge to the power storage device is indicated on a display device. In accordance with an instruction from a user, the power storage device is charged from a charging station.
