Abstract: A storage battery monitoring device according to an aspect of the present invention includes: a plurality of monitoring units attached to a plurality of storage batteries connected in series and/or in parallel; and a management unit capable of wirelessly communicating with the plurality of monitoring units. The management unit sequentially selects identification information about the plurality of monitoring units stored previously, and transmits a connection request message including identification information about a selected monitoring unit to the plurality of monitoring units through wireless communication in order to establish communication with the selected monitoring unit. The management unit further updates identification information about another monitoring unit to identification information about one monitoring unit through the wireless communication when the another monitoring unit is replaced with the one monitoring unit.

Abstract: A lead-acid battery monitoring device includes a plurality of sensor units 20 attached to a plurality of lead-acid batteries 1 connected in series and/or in parallel and a control unit 10 that sequentially establishes wireless communication connection with the plurality of monitoring units 20. The lead -acid battery monitoring device executes a first monitoring operation in which the management unit 10 sequentially receives monitoring data including an internal resistance and a temperature of each lead-acid battery 1 from the plurality of monitoring units 20 and a second monitoring operation in which the management unit 10 sequentially receives monitoring data including the temperature of each lead-acid battery 1 from the plurality of monitoring units 20.

Abstract: An energy storage apparatus, which includes a plurality of energy storage devices, includes: a bus bar which connects the energy storage devices to each other; a wiring; a wiring positioning member, which includes a plurality of guide portions; and a connector holding member, wherein a part of the plurality of guide portions positions the connecting holding member, and wherein an other part of the plurality of guide portions forms a path of the wiring.

Abstract: A lead-acid battery monitoring apparatus includes: sensor units attached to lead-acid batteries connected in series and/or in parallel; and a control unit capable of wireless communication connection with the sensor units. The control unit receives a setting as to whether to prohibit or permit alarm output for each of the lead-acid batteries.
