Abstract

A discharge device includes a switch element connected in parallel to an electrical storage element; a constant current output unit which supplies a constant current to the switch element; and a control unit which gives an on or off instruction to the constant current output unit, wherein a configuration is such that the control unit controls the constant current output unit so as to cause energy with which is charged in the electrical storage element to be discharged while being consumed by the switch element, and within an optional time for which an energization current of the switch element reaches a limiting current of the switch element, turn off the switch element in a region in which the energization current is lower than the limiting current.
