Abstract

A battery secondary use management system for managing a secondary use destination of a battery in use by using information of the battery includes an expired use time prediction unit configured to obtain estimated degradation information of the battery in use and predict an expired use time of the battery in use on the basis of the estimated degradation information which is acquired, and a secondary use destination determining unit configured to determine in advance the secondary use destination of the battery in use before expiration of use on the basis of the expiration-of-use date which is predicted.

First claim

The invention claimed is:

1. A battery secondary use management system for managing a secondary use destination of a battery in use by using information of the battery, comprising:
a first battery management server configured to:
obtain, while the battery is in use in a device, degradation degree information and use mode information of the battery in use through communication with the device including the battery, wherein
the device is a vehicle and the battery in use is an on-board battery in use in the vehicle,
the degradation degree information is indicative of a current capacity of the battery, and
the use mode information comprising at least one of:
a use frequency of the vehicle;
a travel distance in a predetermined period; and
a respective travel distance for each travel; and

predict, while the battery is in use in the device, an expiration-of-use time of the battery in use based on the degradation degree information and the use mode information;

a second battery management server configured to:
predict battery replacement times of batteries used in a plurality of secondary use destination candidates; and

a battery secondary use management server configured to:
determine, while the battery is in use in the device, in advance the secondary use destination of the battery in use before expiration of use based on the expiration-of-use time and the battery replacement times of the batteries used in the plurality of secondary use destination candidates.

2. The battery secondary use management system according to claim 1 , wherein the battery secondary use management server is further configured to:
determine a secondary use destination candidate corresponding to a closest battery replacement time as the secondary use destination of the battery in use,
the closest battery replacement time being a time closest to the expiration-of-use time of the battery in use among kinds of battery replacement time of the plurality of secondary use destination candidates.

3. The battery secondary use management system according to claim 1 , wherein the battery secondary use management server is further configured to:
notify the expiration-of-use time of the battery in use to a user of the battery in use or a system on which the battery in use is mounted.

4. The battery secondary use management system according to claim 1 ,
wherein in a case that the expiration-of-use time of the battery in use is determined in advance, the first battery management server is configured to predict the expiration-of-use time determined in advance as the expiration-of-use time of the battery in use.

5. The battery secondary use management system according to claim 1 ,
wherein a system of the secondary use destination is a stationary power source system.

6. The battery secondary use management system according to claim 1 ,
wherein the battery in use is a battery of a stationary power source system and a system of the secondary use destination is other stationary power source system different from the stationary power source system.

7. The battery secondary use management system according to claim 6 , wherein the first battery management server is further configured to:
calculate time at which a battery capacity of the battery in use reaches 40% of an initial battery capacity based on the degradation degree information of the battery in use; and
predict the calculated time as the expiration-of-use time.

8. The battery secondary use management system according to claim 1 , wherein the battery secondary use management server is further configured to:
determine whether or not the battery in use is available for an on-board use based on the degradation degree information of the battery in use; and
set the secondary use destination of the battery in use to a vehicle when the battery in use is available for the on-board use.

9. The battery secondary use management system according to claim 8 , wherein the battery secondary use management server is further configured to:
determine a user classification of a user of a vehicle which is available for the secondary use destination based on the degradation degree information of the battery in use when the battery in use is available for the on-board use.

10. The battery secondary use management system according to claim 9 , wherein the battery secondary use management server is further configured to:
provide specified information to a vehicle user corresponding to the user classification, the specified information indicating that a secondarily available battery is present.

11. The battery secondary use management system according to claim 1 , wherein a single server comprises the first battery management server and the battery secondary use management server.

12. A battery secondary use management apparatus for managing a secondary use destination of a battery in use by using information of the battery, comprising:
a first battery management server configured to:
obtain expired use time information of the battery in use, the expired use time information being predicted from degradation degree information of the battery in use and use mode information of the battery in use, wherein
the battery is an on-board battery in use in a vehicle,
the degradation degree information is indicative of a current capacity of the battery,
the use mode information comprising at least one of:
a use frequency of the vehicle;
a travel distance in a predetermined period; and
a respective travel distance for each travel; and

a second battery management server configured to obtain battery replacement time information of batteries used in a plurality of secondary use destination candidates which become secondary use destination candidates of the battery in use, through communication with the secondary use destination candidates; and
a battery secondary use management server configured to determine in advance the secondary use destination of the battery in use before expiration of use based on the battery replacement time information of the batteries used in the plurality of secondary use destination candidates and the expired use time information.

13. The battery secondary use management apparatus according to claim 12 ,
wherein the battery secondary use management server is configured to determine in advance a secondary use destination candidate corresponding to a closest battery replacement time as the secondary use destination the battery in use before expiration of use, and
the closest battery replacement time is time closest to the expired use time information of the battery in use obtained by the expired use time information obtaining unit among kinds of battery replacement time of batteries used in the plurality of secondary use destination candidates.

14. The battery secondary use management apparatus according to claim 12 , wherein a single server comprises the first battery management server, the battery secondary use management server and the second battery management server.

15. A method, performed by a first battery management server and a battery secondary use management server, for managing battery secondary use, comprising:
obtaining, by the first battery management server, degradation degree information and use mode information of a battery in use through communication between the first battery management server and a device including the battery, wherein
the device is a vehicle and the battery in use is an on-board battery in use in the vehicle,
the degradation degree information is indicative of a current capacity of the battery, and
the use mode information
