In the present embodiment, for example, the order in which the storage battery module MDL is incorporated into the housing 10A is determined in advance. For example, the storage battery modules MDL are inserted in the order of “B”, “C”,... From the upper left shelf “A” of the housing 10A. When the storage battery module MDL is inserted up to the lowermost shelf “E” of the left shelf, the storage battery modules MDL are inserted in the order of “G”, “H”,. . A connector for the main circuit and the communication circuit is prepared in advance in the storage battery module MDL, and when inserted, the battery management device 16 which is a host device detects the fitting of the connector between the storage battery module MDL and the housing 10A.

  When the storage battery module MDL is fitted, the communication line between the storage battery module MDL and the battery management device 16 is opened, and the battery management device 16 automatically detects the storage battery module MDL, thereby sequentially assigning IDs to the modules. To do.

Canceled. Therefore, by detecting whether or not this short connection pin is fitted, the assembled battery monitoring device 2 and the battery management device 16 can detect the fitting between the storage battery module MDL and the housing 10A. The assembled battery monitoring device 2 and the battery management device 16 can also transmit to the upper management device, for example, the gateway control device 22 that the main circuit wiring and the communication line are securely connected.

It may be attached.

  When it is determined in step SB2 that the storage battery module MDL has been fitted, the battery management device 16 starts communication between the assembled battery monitoring device 2 of the storage battery module MDL and the battery management device 16 (step SB3).

  Subsequently, the battery management device 16 assigns the ID of the storage battery module MDL to the assembled battery monitoring device 2 of the storage battery module MDL with which communication has been established, and the battery management device 16 supports the ID of the storage battery module MDL. The information is recorded in the memory 16M in association with the position of the shelf of the body 10A (step SB4).

  The IDs assigned at this time are, for example, values in ascending order that are sequentially given in the order in which communication is established. Therefore, the user can manage the ID of the storage battery module MDL by setting the order in which the storage battery module MDL is assembled to the housing 10A in advance.

  Subsequently, the battery management device 16 determines whether or not the storage battery module MDL is fitted in all the shelves of the housing 10A (step SB5). If there is an open shelf, is the storage battery module MDL fitted again? It is determined whether or not (step SB2).

  When the storage battery module MDL is fitted to all the shelves of the housing 10A, the battery management device 16 ends the creation of the map.

  As described above, when a plurality of storage battery modules MDL are sequentially inserted into the shelf of the housing 10A in a preset order, the storage battery modules MDL arranged in a predetermined order can be managed with a predetermined identification ID.

In this embodiment, since the storage battery modules MDL are inserted in the order of the shelves “A”, “B”, “C”,..., “F”, “G”, “H”,. The ID of the storage battery module MDL of “A” is “1”, the ID of the storage battery module MDL of “B” is “2”, and the numbers arranged in ascending order are set as IDs.

  Here, for maintenance, the housing MA of the storage battery module MDL may be provided with display means such as a seal or a cap indicating the mounting position of the storage battery module MDL. The operator can distinguish individual storage battery modules MDL based on display means corresponding to the position of the shelf.
