Abstract: A control device (90) equipped with: switches (91) provided in each charging or discharging current path in each of one or more power storage units (40); a control unit (92) that supplies a control signal to the switch (91); and an external input terminal (83) that supplies an external input signal to the switch (91). Each switch (91) has a function for turning off when the control signal and/or the external input signal is a signal for turning off that switch, or a function for turning on when both the control signal and the external input signal are a signal for turning on that switch.

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.
