<P>PROBLEM TO BE SOLVED: To provide a secondary battery which can reduce manufacturing cost even when the secondary battery has a plurality of power storage elements, and by which electrolytic solution is made to be infiltrated quickly inside an electrode group provided in each of the power storage elements, and which has a good usability and high convenience, and to provide a control system for a secondary battery that enables efficient use of the plurality of power storage elements, and a highly convenient lease system for a secondary battery. <P>SOLUTION: A plurality of power storage elements are arranged on the same plane of an exterior case 11 at a predetermined interval L1 in an insulation state, and positive and negative external terminals (6Aa-6Bb) corresponding to the respective power storage elements are provided respectively. By configuring to detect abnormalities of the respective power storage elements via a controller 21 connected with the respective external terminals via voltage detection lines 22 (22A and 22B), a control system electrically disconnecting a connector 24 of the power storage element in which abnormalities are detected is provided. By connecting with an Internet network 28 via a communication unit 27, a lease system that can communicate abnormality information is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
