Abstract

A management system (1) includes: a battery information gathering unit (2) that gathers battery information (31), which is information relating to use histories of individual secondary batteries (10); a battery information database (3) that stores the battery information (31) gathered by the battery information gathering unit (2); and an order reception information gathering unit (4) that gathers order reception information (82), which is information relating to component replacement of a secondary battery. The battery information (31) of the secondary battery (10) specified in the order reception information (82) is extracted from the battery information (31) stored in the battery information database (3).

Claims

1. A secondary battery management system comprising:

a processor configured to gather use information, which is information comprising use histories of individual secondary batteries, wherein the use information comprises a total amount of electricity discharged by a secondary battery and a distance traveled by a vehicle in which the secondary battery is installed; and

a storage configured to store the use information gathered by the processor,

wherein the processor is further configured to gather replacement information, and wherein the replacement information comprises;

information relating to component replacement of the secondary battery,

information specifying an order date, and

information specifying an order source that places an order for the component replacement,

wherein the processor is further configured to extract the use information of the secondary battery specified in the replacement information from the use information stored in the storage,

wherein the processor is further configured to determine if further analysis of the secondary battery is required based on a relationship between the total amount of electricity discharged by the secondary battery and the distance traveled by the vehicle,

wherein the processor is further configured to determine that the secondary battery should be collected if further analysis is required, and

wherein the processor is further configured to issue a collect notification to the order source in relation to the secondary battery when the processor determines that the secondary battery should be collected if further analysis is required based on the relationship between the total amount of electricity discharged by the secondary battery and the distance traveled by the vehicle.

2. The secondary battery management system according to claim 1, wherein the replacement information comprises information for specifying the secondary battery individually.

3. The secondary battery management system according to claim 1, wherein the replacement information comprises information for specifying a vehicle in which the secondary battery is installed.

4. A secondary battery management apparatus comprising:

a storage; and

a controller, wherein the controller is configured to;

obtain use information, which is information comprising use histories of individual secondary batteries, wherein the use information comprises a total amount of electricity discharged by a secondary battery and a distance traveled by a vehicle in which the secondary battery is installed;

execute use acquisition processing to store the use information in the storage;

execute replacement acquisition processing to obtain replacement information, wherein the replacement information comprises information relating to component replacement of a secondary battery, information specifying an order date, and information specifying an order source that places an order for the component replacement; and

execute extraction processing to extract the use information on the secondary battery specified in the replacement information from the use information stored in the storage;

determine whether further analysis of the secondary battery is required based on a relationship between the total amount of electricity discharged by the secondary battery and the distance traveled by the vehicle;

determine that the secondary battery should be collected if further analysis is required; and

issue a collect notification to the order source in relation to the secondary battery when the controller determines that the secondary battery should be collected if further analysis is required based on the relationship between the total amount of electricity discharged by the secondary battery and the distance traveled by the vehicle.

5. A secondary battery management method comprising:

gathering use information, which is information comprising use histories of individual secondary batteries, wherein the use information comprises a total amount of electricity discharged by a secondary battery and a distance traveled by a vehicle in which the secondary battery is installed;

storing the gathered use information in a storage apparatus; and

extracting the use information on a secondary battery specified in replacement information, wherein the replacement information comprises information gathered by the storage apparatus in relation to component replacement of the secondary battery, information specifying an order date, and information specifying an order source that places an order for the component replacement, from the use information stored in the storage apparatus;

determining that further analysis of the secondary battery is required based on a relationship between the total amount of electricity discharged by a secondary battery and the distance traveled by the vehicle;

determining that the secondary battery should be collected; and

issuing a collect notification to the order source for the secondary battery after it is determined that the secondary battery should be collected based on the relationship between the total amount of electricity discharged by the secondary battery and the distance traveled by the vehicle.

6. A secondary battery management method comprising:

gathering use information, which is information comprising use histories of individual secondary batteries, wherein the use information comprises a total amount of electricity discharged by a secondary battery and a distance traveled by a vehicle in which the secondary battery is installed;

storing the gathered use information in a storage apparatus; and

extracting the use information on a secondary battery specified in replacement information, wherein the replacement information comprises information gathered by the storage apparatus in relation to component replacement of the secondary battery, information specifying an order date, and information specifying an order source that places an order for the component replacement, from the use information stored in the storage apparatus;

determining that further analysis of the secondary battery is required based on a relationship between the total amount of electricity discharged by a secondary battery and the distance traveled by the vehicle;

determining that the secondary battery should be collected; and

issuing a collect notification to the order source with instructions to retain the secondary battery after it is determined that the secondary battery should be collected based on the relationship between the total amount of electricity discharged by the secondary battery and the distance traveled by the vehicle.
