Patent attributes
A control module is arranged side by side with a battery module. The control module include a bus bar by which the battery module and an electric load are electrically connected to each other, and a switch by which an electrical connection between the bus bar and the electric load is switched on and off. The control module further includes a current sensor by which a current of the bus bar is detected; a control unit into which an electric signal of the current sensor is inputted, and by which connection switching of the switch is controlled; and a connection terminal by which the current sensor and the control unit are electrically connected to each other. A connection portion between the connection terminal and the current sensor is more closely disposed at a side of the control unit than a connection portion between the bus bar and the switch.
