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.

A control device () equipped with: switches () provided in each charging or discharging current path in each of one or more power storage units (); a control unit () that supplies a control signal to the switch (); and an external input terminal () that supplies an external input signal to the switch (). Each switch () 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.
