A plurality of battery cells is connected in series via a plurality of bus bars. An FPC board is attached to the bus bars. On the FPC board, PTC elements are respectively arranged in close proximity to the bus bars. Each of conductor lines on the FPC board extends between an attachment portion of the bus bar and the PTC element arranged in close proximity to the bus bar, extends between the PTC element and one end of the FPC board, and is connected to a plurality of connection terminals of a printed circuit board. The connection terminals are electrically connected to a detecting circuit.

A battery module includes a plurality of battery cells, and includes a voltage bus bar and a voltage/current bus bar that connect electrodes of the plurality of battery cells to one another. Solder traces are formed in regions that are spaced apart from each other in the voltage/current bus bar. Furthermore, the battery module includes an amplifying circuit and a detecting circuit. The amplifying circuit amplifies a voltage between the solder traces formed in the voltage/current bus bar. The detecting circuit detects the voltage between the solder traces amplified by the amplifying circuit.

A battery system includes battery modules. Each of the battery modules has an end surface member formed of a rectangular plate. The battery modules are arranged to form a line such that the end surface member of the battery module comes in contact with the end surface member of the battery module. In this state, the end surface member of the battery module is joined to the end surface member of the battery module by screws and nuts.
