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.
