Abstract

A power storage device includes a storage battery, a mounting unit that detachably mounts the power storage device on a motor-driven moving object, an output controller that controls output of driving power from the storage battery to the motor-driven moving object, and a controller that, when the motor-driven moving object is within a particular area, causes the output controller to reduce the driving power supplied from the power storage device to the motor-driven moving object compared to the driving power when the motor-driven moving object is outside the particular area.

First claim

What is claimed is:

1 . A power storage device comprising:
a storage battery; a mounting unit that detachably mounts the power storage device on a motor-driven moving object; an output controller that controls output of driving power from the storage battery to the motor-driven moving object; and a controller that, when the motor-driven moving object is within a particular area, causes the output controller to reduce the driving power supplied from the power storage device to the motor-driven moving object compared to the driving power when the motor-driven moving object is outside the particular area.

2 . The power storage device according to claim 1 , wherein the output controller outputs the driving power which is a direct current.

3 . The power storage device according to claim 1 , wherein
the output controller comprises a switching element that turns on or off supply of the driving power from the power storage device to the motor-driven moving object, and the controller causes the output controller to reduce the driving power using the switching element.

4 . The power storage device according to claim 1 , wherein the controller causes the output controller to intermittently reduce the driving power supplied from the power storage device to the motor-driven moving object.

5 . The power storage device according to claim 1 , wherein the controller causes the output controller to reduce the driving power by supplying driving power having a pulse waveform to the motor-driven moving object and reducing a pulse width of the driving power.

6 . The power storage device according to claim 1 , further comprising a communicator that communicates with a mobile terminal, wherein if, when the motor-driven moving object is within a particular area, the communicator receives a command to reduce the driving power from the mobile terminal, the controller causes the output controller to reduce the driving power.

7 . The power storage device according to claim 6 , wherein the communicator receives the command from the mobile terminal which is paired with the power storage device.

8 . The power storage device according to claim 1 , further comprising a communicator that communicates with a mobile terminal, wherein
when the communicator acquires information about a location of the motor-driven moving object from the mobile terminal, the controller determines whether the motor-driven moving object is within a particular area, on the basis of the information about the location of the motor-driven moving object, and if the controller determines that the motor-driven moving object is within a particular area, the controller causes the output controller to reduce the driving power.

9 . The power storage device according to claim 8 , wherein the communicator receives the information from the mobile terminal which is paired with the power storage device.

10 . The power storage device according to claim 1 , further comprising a communicator that communicates with a mobile terminal, wherein when the communicator receives, from the mobile terminal, information indicating that the motor-driven moving object is within a particular area, the controller causes the output controller to reduce the driving power.

11 . The power storage device according to claim 10 , wherein the communicator receives the information from the mobile terminal which is paired with the power storage device.

12 . A method comprising:
controlling, by an output controller included in a power storage device, output of driving power from a storage battery in the power storage device to a motor-driven moving object, the power storage device being detachably mounted on the motor-driven moving object; and when the motor-driven moving object is within a particular area, reducing, by the output controller, the driving power supplied from the power storage device to the motor-driven moving object compared to the driving power when the motor-driven moving object is outside the particular area.
