    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.

    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 a storage-battery control system, an insulating communication unit couples a controller and a plurality of battery modules coupled together in series to configure a storage battery unit. A floating grounding pattern of the controller is divided into a first floating grounding pattern and a second floating grounding pattern. The plurality of battery modules in the storage battery unit is divided into a first zone battery module group and a second zone battery module group so that the battery modules belonging to the first zone battery module group correspond to the first floating grounding pattern, while the battery modules belonging to the second zone battery module group correspond to the second floating grounding pattern. An insulating communication unit couples the respective battery modules.
