Abstract

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.

Claims

1. A displaying system for displaying information related to state of degradation evaluated for a power storage device for running mounted on a vehicle, comprising:

a data processing unit for processing said information related to the state of degradation to a first display item for a user of said vehicle, a second display item for a dealer in charge of maintenance of said vehicle, and a third display item for a manufacturer of said vehicle; and

a display unit for displaying said information processed by said data processing unit to said first to third display items, to said user, said dealer and said manufacturer.

2. The displaying system according to claim 1, wherein

said first display item includes information related to life of said power storage device.

3. The displaying system according to claim 2, wherein

said information related to life of said power storage device includes information related to lifetime guarantee designated by law in a region where said vehicle is used, and information related to life evaluated based on actual use of said power storage device.

4. The displaying system according to claim 1, wherein

said second display item includes information related to state of malfunction occurrence of said power storage device.

5. The displaying system according to claim 1, wherein

said third display item includes information indicating expected degradation of said power storage device analyzed in advance, and information indicating actual degradation evaluated based on actual use of said power storage device.

6. The displaying system according to claim 1, further comprising

a display control unit for switching said information to be displayed on said display unit to any of said first to third display items in accordance with a request from a user of said display unit.

7. A method for displaying information related to state of degradation evaluated for a power storage device for running mounted on a vehicle, comprising the steps of:

processing said information related to the state of degradation to a first display item for a user of said vehicle, a second display item for a dealer in charge of maintenance of said vehicle, and a third display item for a manufacturer of said vehicle; and

displaying said information processed to said first to third display items, to said user, said dealer and said manufacturer.

8. The method according to claim 7, wherein

said first display item includes information related to life of said power storage device.

9. The method according to claim 8, wherein

said information related to life of said power storage device includes information related to lifetime guarantee designated by law in a region where said vehicle is used, and information related to life evaluated based on actual use of said power storage device.

10. The method according to claim 7, wherein

said second display item includes information related to state of malfunction occurrence of said power storage device.

11. The method according to claim 7, wherein

said third display item includes information indicating expected degradation of said power storage device analyzed in advance, and information indicating actual degradation evaluated based on actual use of said power storage device.

12. The method according to claim 7, further comprising the step of

switching, in accordance with a request from a user who uses said information related to state of degradation, said information to be displayed to said user to any of said first to third display items.
