Abstract: A battery management system includes a circuit board having a first region provided with a voltage measuring unit, a second region provided with a controller, a relay region that is disposed at a first insulation distance from the first region and at a second insulation distance from the second region, and a third region provided with an interface connecting unit. The third region is disposed at a third insulation distance from the second region. The third insulation distance is shorter than each of the first and the second insulation distances. The battery management system further includes a first insulating device connecting between the fist region and the relay region, a second insulating device connecting between the relay region and the second region, and a third insulating device connecting between the second region and the third region.

Abstract: In each of battery modules, a processing circuit manages a battery unit connected to a power line. A communication circuit communicates data to be transmitted or received by the processing circuit. An isolated circuit insulates in a direct current between a first terminal of the communication circuit and a positive-electrode terminal or a negative-electrode terminal of the battery unit, and between a second terminal of the communication circuit and a conductive body to be a common potential of a plurality of the battery modules except for the power line.

Abstract: In a power storage system, each of a plurality of power storage modules includes at least one cell, and the plurality of power storage modules are connected in series. A management device manages the plurality of power storage modules. Each of the plurality of power storage modules contains a first insulation unit having a primary side and a secondary side that are insulated from each other. The first insulation unit outputs a signal containing information of at least one cell to a communication line. The signal is referenced to predetermined standard voltage between a voltage at one end and a voltage at the other end of the plurality of power storage modules. The management device contains a second insulation unit having a primary side and a secondary side that are insulated from each other, and a circuit unit insulated from the communication line by the second insulation unit.
