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 management device includes: a first communication unit that receives state data of an energy storage device; a second communication unit that receives identification data transmitted from a host device; an external terminal to which a switch is connected and which receives an input from the switch; a state detection unit that detects a state of the switch via the external terminal; and a processing unit that stores the identification data in a storage unit when the second communication unit receives the identification data and the state detection unit detects that the switch is in a specific state, in which the state data received by the first communication unit is transmitted to the host device or another device in association with the identification data stored in the storage unit.

Abstract: An energy storage device managing apparatus that estimates a degradation amount of a full charge capacity of an energy storage device, the energy storage device managing apparatus includes: a measurement unit that measures a temperature of the energy storage device in a power supply state; a timing unit that measures time in a power non-supply state; and a controller. The controller performs interpolation based on a first temperature measured immediately before the energy storage device becomes the power non-supply state, and a second temperature initially measured after the energy storage device returns to the power supply state, decides a temperature of the energy storage device from a measurement time of the first temperature to a measurement time of the second temperature, and estimates the degradation amount of the full charge capacity based on the decided temperature.
