  "textContent": "An energy storage apparatus includes a plurality of energy storage devices connected in series, a voltage detection circuit that detects voltages of the plurality of energy storage devices, and a discharge circuit that discharges the energy storage devices individually, and a BMU having a control unit, in which the control unit discharges only an energy storage device having a highest voltage among the plurality of energy storage devices. Further, charging is stopped when a first duration elapses in a state that a cell voltage of the energy storage device having the highest voltage exceeds a first voltage threshold, or charging is stopped when a second duration elapses in a state that the cell voltage of the energy storage device having the highest voltage exceeds a second voltage threshold.",
