  "textContent": "A power management device includes a control unit that controls a converter capable of bidirectionally converting between an external bus voltage and an internal bus voltage in a first power feeding system. When an amount of stored electric power of the first power feeding system is less than a first storage threshold value, the control unit sets a target value of the external bus voltage to a first power reception target value corresponding to a first transmission power value in a first power transmission request transmitted to an upper power management device. When the amount of stored electric power exceeds a second storage threshold value, the control unit sets the target value of the external bus voltage to a first power transmission target value corresponding to a second transmission power value in a second power transmission request received from a second power feeding system.",
