POWER SUPPLY SYSTEM AND DISCHARGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power supply system capable of discharging the power to power wirings from a battery mounted on an electric vehicle according to the power amount used by a user even when the electric vehicle is separated away from the user.SOLUTION: The power supply system includes: a measuring unit 10; a discharge device 20; and a controller 30. The measuring unit 10 measures the power amount that a user 1 receives from the power system 51. The discharge device 20 supplies the power to a power wiring 50 from a battery 41 for travelling mounted on an electric vehicle 40. The controller 30 controls the discharge device 20 to adjust the power amount to supply to the power wiring 50 from the battery 41. The controller 30 includes a communication section 31 and an adjusting section 32. The communication section 31 acquires the power amount measured by the measuring unit 10 via communication with the measuring unit 10. The adjusting section 32 adjusts so that the power amount supplied from the battery 41 to the power wiring 50 is the power amount equivalent to at least a part of the power amount measured by the measuring unit 10.
