Abstract
A discharge circuit includes a plurality of burden circuits that are electrically connected in parallel to a plurality of power storage units, respectively. Each of the plurality of burden circuits includes (i) a resistor and a switch that are electrically connected in series between both ends of a corresponding one of the plurality of power storage units, and (ii) a control terminal that controls the switch according to a potential of the control terminal. The plurality of burden circuits are electrically connected in series between a positive electrode and a negative electrode. The control terminal of a n+1-th burden circuit from a reference point is electrically connected, via the switch of the n-th burden circuit from the reference point, to a reference point side terminal of a n-th power storage unit from the reference point. The reference point is the positive electrode or the negative electrode.
