Abstract

In a system in which a plurality of batteries can be loaned out, a battery that is carried in alone has a physical load information acquisition component. The physical load information acquisition component acquires physical load information about the battery. The physical load information acquisition component has at least one of the following: an acceleration sensor that senses acceleration information about the battery, a vibration sensor that acquires vibration information about the battery, a strain sensor that senses strain information about the battery, an impact sensor that acquires impact information about the battery, and a pressure sensor that acquires pressure information about the battery.

First claim

The invention claimed is:

1. A system comprising:
a battery that is carried in alone in a system in which a plurality of batteries are to be loaned out, the battery comprising: a physical load information acquisition component that acquires physical load information for the battery, and
an information processing device,
wherein the information processing device has:
an output information acquisition component that acquires information from the physical load information acquisition component of the battery; and
a physical load information analysis component that uses information from the output information acquisition component to analyze a physical load on the battery, and
wherein the physical load information analysis component has a damage calculator that uses information acquired by the physical load information acquisition component to calculate a degree of damage to the battery based on a previously obtained correlation between information acquired by the physical load information acquisition component and an amount of separation and breakage of structural components and support members of the battery.

2. The system according to claim 1 ,
wherein the physical load information acquisition component has at least one of the following:
an acceleration sensor that senses acceleration information about the battery, a vibration sensor that acquires vibration information about the battery,
a strain sensor that senses strain information about the battery, an impact sensor that acquires impact information about the battery,
a pressure sensor that acquires pressure information about the battery,
a tilt sensor that acquires inclination information about the battery,
a position sensor that acquires position information about the battery, and a speed sensor that senses speed information about the battery.

3. The system according to claim 1 ,
further comprising a storage component that stores the physical load information acquired by the physical load information acquisition component.

4. The system according to claim 1 ,
further comprising a communication component that sends the physical load information acquired by the physical load information to an information processing device that analyzes the physical load information.

5. The system according to claim 4 ,
wherein the information processing device is a virtual server in cloud computing.

6. The system according to claim 1 ,
wherein the physical load information analysis component further has a usability determination component that determines whether or not the battery can be used, on the basis of the degree of damage calculated by the damage calculator.

7. The system according to claim 1 ,
wherein the physical load information analysis component has a usage state determination component that uses information acquired by the output information acquisition component to determine a usage state of the battery.

8. A battery management method for managing a battery that is carried in alone when a plurality of batteries are to be loaned out, the battery management method comprising:
acquiring physical load information for the battery; and
using the physical load information acquired to analyze a physical load on the battery,
wherein the physical load information analysis comprises:
using the physical load information to calculate a degree of damage of the battery based on a previously obtained correlation between the physical load information and an amount of separation and breakage of structural components and support members of the battery.

9. The battery management method according to claim 8 ,
wherein the physical load information analysis further comprises:
determining whether or not the battery can be used, on the basis of the degree of damage calculated in the damage calculation.

10. The battery management method according to claim 8 ,
wherein the physical load information analysis further comprises:
using the physical load information acquired in the physical load information acquisition to determine a usage state of a battery.

11. A battery management program for managing a battery that is carried in alone when a plurality of the batteries are to be loaned out, the battery management program causing a computer to execute a battery management method comprising:
acquiring physical load information for the battery; and
using the physical load information acquired to analyze a physical load on the battery,
wherein the physical load information analysis includes,
using the physical load information to calculate a degree of damage to the battery based on a previously obtained correlation between the physical load information and an amount of separation and breakage of structural components and support members of the battery.

12. A non-transitory computer readable recording medium on which is recorded the battery management program according to claim 11 , wherein the recording medium is configured to be processed by a computer.
