摘要
An energy storage device 50 includes external connections 51 and 52, an energy storage device 60, a switch 53 located in a path 55P from the energy storage device 60 to the external connection 51, a measurement unit 150, which measures a current and a voltage of the energy storage device 60,and an administrative unit 130. The measuring unit 150 and the administrative unit 130 receive a power supply from the energy storage device 60. A minimum operating voltage V1 of the administrative unit 130 is lower than a minimum operating voltage V2 of the measuring unit 150. The control unit 130 interrupts an external discharge through the external connection 52 by controlling the switch 53 when the voltage of the energy storage device 60 falls below a threshold voltage V0 greater than or equal to the minimum operating voltage V2 of the measuring unit 150,and the unit 130 estimates the capacity of the energy storage device 60 after any time t1 in a first period in which the voltage of the energy storage device 60 decreases from the threshold voltage V0 to the minimum operational voltage V2 of the unit 150, based on an expired period from any time t1.
