PROBLEM TO BE SOLVED: To provide a sensor unit which can simplify a step for assembling a voltage detection unit to a battery.SOLUTION: A sensor unit 1 provided on a vehicle detects status information on batteries 3a to 3d in which a plurality of cells are connected in series. The sensor unit 1 comprises: first connectors 9a to 9d, provided to circuit modules 5a to 5d fitted to the batteries 3a to 3d, which are electrically connected to respective terminals brought into conduction with respective ends of the plurality of cells; and second connectors 15a to 15d, for detecting the status information on the batteries 3a to 3d, which are provided to voltage detection units 11a to 11d housing boards for controlling the batteries 3a to 3d, and which are electrically connected to the boards. The first connectors 9a to 9d are fitted to the second connectors 15a to 15d.SELECTED DRAWING: Figure 1 |
