First Claim
1. A secondary battery module comprising:
- an assembled battery formed by connecting a plurality of cells;
a battery information storage means for storing as battery information at least one of electrical characteristic information and usage history information on the secondary battery module or the assembled battery;
first communications interface means, which is provided as a connection unit to which a battery controller that executes battery control by acquiring the battery information is connectable, and which when connected to the battery controller, functions to send the battery information stored in the battery information storage means to the battery controller, and also to receive the battery information outputted from the battery controller and send the received battery information to the battery information storage means;
second communications interface means for sending and receiving the battery information;
a control circuit for controlling reading and writing of the battery information from and into the battery information storage means; and
a housing, which houses the assembled battery, the battery information storage means, and the control circuit, and on which the first and second communications interface means are provided,wherein the second communications interface means is provided as a connection unit to which an external device that handles information that is necessary for reuse of the secondary battery module is connectable, the second communications interface means functions to send to the external device and as information that is necessary for reuse of the secondary battery module the battery information stored in the battery information storage means when it is detected that the battery controller is separated from the secondary battery module and the external device is connected, and the second communications interface means functions to receive as information to be stored in the battery information storage means the battery information that is outputted from the external device and to send the received battery information to the battery information storage means when the secondary battery module is to be reused and the external device is connected, andwherein the control circuit functions to read from the battery information storage means the battery information stored in the battery information storage means when the battery information stored in the battery information storage means is to be sent to the second communications interface means, and the control circuit functions to, when the battery information is sent to the battery information storage means from the second communications interface means, write into the battery information storage means the battery information that is sent to the battery information storage means.

Abstract
A secondary battery module includes a battery information storage unit for storing electric characteristic information and usage history information of the secondary battery module. A battery information management device and a terminal device respectively include interfaces to be connected to the secondary battery module. The battery information management device is provided with a battery information database. The battery information management device is connected to the terminal device through a communications network. In this way, battery information stored in the battery information storage unit, which is acquired by the battery information management device and the terminal device, is accumulated in the battery information database. Moreover, the battery information management device grades the secondary battery module for reuse based on the battery information and a predetermined threshold.
