Abstract

The present invention serves to reduce the costs associated with the overall life cycle of storage batteries by performing support so that a plurality of batteries are transferred between and used at a plurality of facilities. This storage battery transfer support device comprises: a collection unit that collects battery information representing the status of each battery used at a plurality of facilities; a battery information storage unit that stores the battery information collected by the collection unit; and a deterioration prediction unit that, on the basis of the battery information stored in the battery information storage unit, predicts deterioration of storage batteries that have been transferred between and used at a plurality of facilities.

First claim

The invention claimed is:

1. A storage battery relocation assistance method, performed by a storage battery relocation assistance apparatus comprising a processor having a plurality of sections configured to execute instructions stored in a memory, the storage battery relocation assistance method comprising the steps of:
collecting battery information representing a state of a plurality of storage batteries used in a plurality of facilities, through one of or both a communication network and a storage medium;
storing, in a battery information storing section, the battery information collected during the collecting step; and
predicting, by a deterioration prediction section, deterioration of the plurality of storage batteries when the plurality of storage batteries are relocated and used among the plurality of facilities, based on the battery information stored in the battery information storing section.

2. The storage battery relocation assistance method according to claim 1 , further comprising the steps of:
storing, in a requirement information storing section, requirement information for a storage battery in the plurality of facilities;
determining, by a relocation determination section, a relocation schedule including relocation time and a relocation destination when the plurality of storage batteries are relocated and used in the plurality of facilities, based on a prediction result in the predicting and the requirement information stored in the requirement information storing section; and
outputting, from an information output section, information on the relocation schedule determined by the determining step.

3. The storage battery relocation assistance method according to claim 1 , wherein:
the plurality of facilities include a plurality of vehicles each of which runs with electric power from a storage battery, a plurality of residential facilities in each of which an appliance is operated with electric power from a storage battery, and a plurality of factory facilities in each of which an industrial appliance is operated with electric power from a storage battery; and
the deterioration prediction section predicts deterioration of the plurality of storage batteries according to a relocation pattern for first using each of the plurality of storage batteries in any of the plurality of vehicles and then relocating the each of the plurality of storage batteries to another facility.

4. The storage battery relocation assistance method according to claim 2 , wherein:
the plurality of facilities include a plurality of vehicles each of which runs with electric power from a storage battery, a plurality of residential facilities in each of which an appliance is operated with electric power from a storage battery, and a plurality of factory facilities in each of which an industrial appliance is operated with electric power from a storage battery; and
the deterioration prediction section predicts deterioration of the plurality of storage batteries according to a relocation pattern for first using each of the plurality of storage batteries in any of the plurality of vehicles and then relocating the each of the plurality of storage batteries to another facility.

5. The storage battery relocation assistance method according to claim 1 , wherein the plurality of storage batteries include one of or both a new storage battery to be newly supplied and a collected secondhand storage battery.

6. The storage battery relocation assistance method according to claim 2 , wherein the relocation determination section determines the relocation schedule by performing a calculation process for comprehensively improving requirement sufficiency levels of a plurality of determination requirements representing relocation conditions for a storage battery.

7. The storage battery relocation assistance method according to claim 6 , wherein the plurality of determination requirements include a requirement of setting relocation time in a way that makes the relocation time close to a time when performance of a storage battery used in each of the facilities reaches near a lower limit of performance required for the facility.

8. The storage battery relocation assistance method according to claim 6 , wherein the plurality of determination requirements include a requirement of relocating, before an electric power supply amount from a storage battery required for each of the facilities is no longer maintained, another storage battery to this facility for maintaining the required electric power supply amount.

9. The storage battery relocation assistance method according to claim 6 , wherein the plurality of determination requirements include a requirement of reducing a variation in deterioration degrees of a plurality of storage batteries used in one of the facilities.

10. The storage battery relocation assistance method according to claim 6 , wherein:
the requirement information includes information on an installation space for a storage battery in each of the facilities; and
the plurality of determination requirements include a requirement of increasing a usage rate of the installation space for a storage battery in each of the facilities.

11. The storage battery relocation assistance method according to claim 6 , wherein:
the plurality of storage batteries include a new storage battery to be newly supplied; and
the plurality of determination requirements include a requirement of reducing frequency of supplying the new storage battery in the facilities other than the plurality of vehicles.

12. The storage battery relocation assistance method according to claim 2 , wherein:
the deterioration prediction section predicts deterioration of each of the plurality of storage batteries when the each of the plurality of storage batteries is relocated in a plurality of relocation patterns among the plurality of facilities; and
the relocation determination section determines the relocation schedule with reference to results of deterioration prediction for relocation in the plurality of relocation patterns.

13. The storage battery relocation assistance method according to claim 1 , wherein
the battery information includes log information on a voltage when each of the plurality of storage batteries is charged and discharged, log information on a current when each of the plurality of storage batteries is charged and discharged, log information on each temperature of the plurality of storage batteries, log information on each state of charge of the plurality of storage batteries, log information on each deterioration state of the plurality of storage batteries, or log information on charge and discharge allowable electric power of each of the plurality of storage batteries.

14. The storage battery relocation assistance method according to claim 2 , wherein the requirement information includes information on supply electric power from a storage battery promised to a user of each of the facilities, information on a capacity of a storage battery promised to the user of each of the facilities, and information on an installation space for a storage battery in each of the facilities.

15. The storage battery relocation assistance method according to claim 14 , wherein the relocation determination section determines the relocation schedule, based on the information on the installation space with an assumption that a larger installation space allows relocation of a larger number of progressively deteriorated storage batteries.

16. The storage battery relocation assistance method according to claim 2 , wherein the predicting of deterioration by the
