Abstract: In each of battery modules (120) of a battery block (100) configuring a battery management system (10), a first insulating device having a first insulation distance is disposed between a first region (132) in which a battery side controller (146) is installed and a second region (134) in which a first communication unit (150) is installed. In a control device (200) coupled to the battery block (100) with a communication line, a second insulating device (234) having a second insulation distance is disposed between a relay region (222) and a third region (220) in which a second communication unit is installed, and a third insulating device (236) having a third insulation distance is disposed between the relay region (222) and a fourth region (224) in which a control controller unit (238) is installed.

Abstract: A management device manages a plurality of power storage devices interconnected in parallel. In the management device, a halt controller halts an operation of at least one of the plurality of power storage devices during a period in which charged/discharged power between the plurality of power storage devices and a load is less than a set value. During the period in which the charged/discharged power is less than the set value, for example, the halt controller, by turns, halts an operation of one of the plurality of power storage devices at a set time interval.

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.
