Battery, battery pack, battery charger, and battery charging system
First Claim
1. A battery comprising a plurality of battery cells interconnected in series, each battery cell having:
- a contactless communication control block configured to execute contactless communication as a transponder and a reader/writer based on electromagnetic induction;
a first antenna configured to execute the contactless communication as the transponder;
a second antenna configured to execute the contactless communication as the reader/writer; and
a battery control block configured to control a charge operation of a cell block;
wherein,the contactless communication control block communicates, in a contactless manner, a charge state of the cell block supplied from the battery control block with the contactless communication control block of the battery cell adjacent to one of the connection sides of the cell block, andthe first antenna is arranged at one end portion of the battery and the second antenna is arranged at an opposite end portion of the battery with respect to a length direction of the battery.

Abstract
Disclosed herein is a battery. The battery includes a contactless communication control block configured to execute contactless communication as a transponder and a reader/writer which are based on electromagnetic induction. The battery further includes an antenna configured to execute the contactless communication as the transponder; and an antenna configured to execute the contactless communication as the reader/writer. The battery further includes a battery control block configured to control a charge operation of a cell block. The contactless communication control block communicates, in a contactless manner, a charge state of the cell block supplied from the battery control block.
