20100007481 | SYSTEM AND METHOD FOR DISPLAYING DEGRADATION OF POWER STORAGE DEVICE - A degradation evaluating unit collects data related to a power storage device from a vehicle through a power cable, and based on the collected data, evaluates the state of degradation of the power storage device. A data processing unit reads data related to the state of degradation of the power storage device evaluated by degradation evaluating unit from a storage unit, and processes the read data related to the state of degradation to a first display item for a user, a second display item for a dealer and a third display item for a manufacturer. A display control unit controls display of the data processed by data processing unit on a display terminal. | 01-14-2010 |
20100010704 | DEGRADATION DETERMINING APPARATUS FOR POWER STORAGE DEVICE AND DEGRADATION DETERMINING METHOD FOR POWER STORAGE DEVICE - A vehicle identifying unit obtains an identification number of a vehicle from the vehicle. A first evaluation unit evaluates a degradation state of a power storage device based on the use history of the power storage device obtained from the vehicle, using data analyzed beforehand concerning the relation between the use history and the degradation state of the power storage device. A second evaluation unit evaluates a degradation state of the power storage device using data collected when the power storage device of the vehicle is charged from a power station or when power is fed from the vehicle to the power station. A degradation determining unit determines the degradation state of the power storage device based on the degradation states evaluated by the first and second evaluation units. | 01-14-2010 |
20100102776 | 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 - 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. | 04-29-2010 |
