  "textContent": "A charge-discharge device includes a DC-DC converter configured to be electrically connected to a secondary battery, an inverter electrically connected to the DC-DC converter, a main charging terminal electrically connected to the inverter, a voltage detector for detecting a voltage of the main charging terminal, and a control circuit electrically connected to the DC-DC converter, the inverter, and the voltage detector. While the secondary battery is charged with a voltage input to the main charging terminal, when the voltage detected by the voltage detector is a DC voltage, the control circuit switches, according to the voltage, between an operation to cause the inverter to supply the voltage substantially intactly to the DC-DC converter, and cause the DC-DC converter to charge the secondary battery and an operation to cause the inverter to function as a DC voltage conversion circuit that converts the voltage and supplies the converted voltage to the DC-DC converter, and cause the DC-DC converter to charge the secondary battery. This charge-discharge device enables secondary batteries to interchange electric power with each other via a simple, light-weight outlet cable.",
