Battery pack
First Claim
1. A battery pack having a housing and a secondary battery inside the housing, comprising:
- a communicator configured to perform short-distance wireless communication with battery packs with a same structure as the battery pack;
a generator configured to generate response information including information related to a status of the secondary battery in the battery pack based on a request signal that is a request for information related to the status of the secondary battery, wherein when the communicator receives the request signal from a first battery pack, the generator generates the response information based on the request signal that the communicator receives from the first battery pack; and
a control circuitry configured to cause the communicator to transmit the response information to an entity from which the communicator receives the request signal and to transmit a second request signal to another battery pack, wherein when the communicator receives the request signal from the first battery pack, the another battery pack is a second battery pack differing from the first battery pack,wherein the communicator is further configured to perform the short-distance wireless communication with an information processing terminal having a display and being driven by a power source other than any of the battery packs,when the communicator receives the request signal from the information processing terminal, the generator generates the response information based on the request signal, which the communicator receives from the information processing terminal, andthe generator generates the response information to further include information indicating a positional relationship between the battery pack and the second battery pack.

Abstract
A battery pack having a housing and a secondary battery inside the housing, and including a communicator that receives an instruction related to the secondary battery from an external communication terminal device via short-distance wireless communication and a controller that executes an operation in accordance with the instruction by using a status of the secondary battery. The external communication terminal device, by transmitting to the battery pack the instruction, which is related to the status of the secondary battery, acquires a response that is in accordance with the status of the secondary battery from the battery pack, thereby facilitating checking of secondary battery state.

15. A battery pack having a housing and a secondary battery inside the housing, comprising:
-
a communicator configured to perform short-distance wireless communication with battery packs with a same structure as the battery pack; a generator configured to generate response information including information related to a status of the secondary battery in the battery pack based on a request signal that is a request for information related to the status of the secondary battery, wherein when the communicator receives the request signal from a first battery pack, the generator generates the response information based on the request signal that the communicator receives from the first battery pack; a control circuitry configured to cause the communicator to transmit the response information to an entity from which the communicator receives the request signal and to transmit a second request signal to another battery pack, wherein when the communicator receives the request signal from the first battery pack, the another battery pack is a second battery pack differing from the first battery pack; and a side surface antenna that is for the near-field communication, the side surface antenna connected with the communicator and provided to one of the left and right surfaces, wherein the communicator performs the short-distance wireless communication with at least one other battery pack that is adjacent to the battery pack in an arrangement where the battery pack and the battery packs with the same structure are linearly disposed in a same orientation, wherein the housing is hexahedral, and has top and bottom surfaces in a height direction, left and right surfaces in a width direction, and front and rear surfaces in a depth direction, in the arrangement, the battery pack and the battery packs with the same structure are linearly disposed one on top of another in the height direction, the short-distance wireless communication is near-field communication, and the battery pack further comprises communication antennas for the near-field communication, the communication antennas being connected with the communicator and composed of a communication antenna provided to the top surface and a communication antenna provided to the bottom surface, wherein when the communicator receives the request signal from the first battery pack via one of the communication antennas, the control circuitry causes the communicator to transmit the request signal to the second battery pack from the other one of the communication antennas, and wherein when the communicator receives the request signal from the first battery pack via one of the communication antennas, and does not receive a response to the request signal following transmission of the request signal to the second battery pack from the other one of the communication antennas, the control circuitry causes the communicator to transmit the request signal from the side surface antenna.
