Classification: CPC B  H  Y | IPC B  H

Claim 0:
1. A charge/discharge device, comprising:
an electric power receiving connector including a first positive-electrode and a first negative-electrode, the electric power receiving connector being configured (i) to be removably connected to a charger and (ii) to receive a charging power from the charger, the charging power being an electric power for charging an electric vehicle;
an electrical energy storage device including a second positive-electrode and a second negative-electrode and being configured to be charged with the charging power;
a positive-electrode path extending from the first positive-electrode to the second positive-electrode;
a negative-electrode path extending from the first negative-electrode to the second negative-electrode;
a first switcher circuit and a second switcher circuit respectively including a first switch and a second switch, the first switch and the second switch being (i) respectively on the positive-electrode path and the negative-electrode path and (ii) configured to respectively complete or interrupt the positive-electrode path and the negative-electrode path;

a first electric power outputter connected to the negative-electrode path, the first electric power outputter being configured (i) to be removably connected to a first external device and (ii) to output a first discharge power to the first external device;
a second electric power outputter connected to the negative-electrode path, the second electric power outputter being configured (i) to be removably connected to a second external device and (ii) to output a second discharge power to the second external device, and the second electric power outputter being distinct from the first electric power outputter;
an electric power generator configured to generate the first discharge power and the second discharge power based on a stored electrical energy in the electrical energy storage device; and
a controller configured to perform a charge control of the electrical energy storage device and/or a discharge control of the electrical energy storage device.
