Abstract

An electrical-power storage device includes: a storage battery; a movement detector that detects movement of the electrical-power storage device including the storage battery; a reporter that reports that the electrical-power storage device has an abnormality to outside; and a controller that causes the reporter to report that the electrical-power storage device has an abnormality, when the movement detector detects movement of the electrical-power storage device, and the storage battery is not executing discharging.

Claims

1. An electrical-power storage device, comprising:

a storage battery;

a movement detector that detects a movement of the electrical-power storage device including the storage battery;

a reporter that reports that the electrical-power storage device has an abnormality to outside of the electrical power storage device; and

a controller

that determines whether or not the storage battery is being discharged during the detected movement of the electrical-power storage device,

that causes the reporter to report that the electrical-power storage device has the abnormality, when the movement detector detects the movement of the electrical-power storage device while the controller determines that the storage battery is not being discharged, and

that does not cause the reporter to report that the electrical-power storage device has the abnormality even when the movement detector detects the movement of the electrical-power storage device while the controller determines that the storage battery is being discharged.

2. The electrical-power storage device according to claim 1, further comprising:

a communicator that performs a short-range wireless communication with an information terminal of a user of the electrical-power storage device,

wherein, when the movement detector detects the movement of the electrical-power storage device while the controller determines that the storage battery is not being discharged, the controller attempts to communicate with the information terminal via the communicator,

when the communication succeeds, the controller does not cause the reporter to report that the electrical-power storage device has the abnormality, and

when the communication fails, the controller causes the reporter to report that the electrical-power storage device has the abnormality.

3. The electrical-power storage device according to claim 1, further comprising:

a terminator that terminates use of the storage battery,

wherein, after causing the reporter to report that the electrical-power storage device has the abnormality, the controller causes the terminator to terminate the use of the storage battery.

4. The electrical-power storage device according to claim 3,

wherein the controller receives a request for starting a new use of the storage battery after the terminator terminates the use of the storage battery, and the controller does not permit the use of the storage battery in response to the request.

5. The electrical-power storage device according to claim 3,

wherein the controller does not permit charging of the storage battery after the terminator terminates the use of the storage battery.

6. The electrical-power storage device according to claim 3,

wherein the controller does not permit discharging of the storage battery after the terminator terminates the use of the storage battery.

7. The electrical-power storage device according to claim 3,

wherein the movement detector detects a change in a location of the electrical-power storage device.

8. The electrical-power storage device according to claim 1,

wherein the abnormality is that the electrical-power storage device is stolen.

9. The electrical-power storage device according to claim 1,

wherein the controller causes the reporter not to report the abnormality regardless of whether or not the storage battery is determined to be discharging when the movement detector does not detect the movement of the electrical-power storage device.

10. The electrical-power storage device according to claim 1, wherein the movement of the battery is detected based on a detected acceleration of the battery by an acceleration sensor.
