NON-CONTACT POWER SUPPLY DEVICE AND NON-CONTACT POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply device and a frame crack detection method, capable of detecting a crack on a frame at an earlier stage.SOLUTION: A non-contact power supply device 100 includes a power transmission coil 12 and transmits power to a power reception coil 22 provided on the vehicle 200 side by using magnetic coupling with the power reception coil 22 in a non-contact manner. The non-contact power supply device 100 comprises: a ground side coil frame 102 for accommodating the power transmission coil 12; a pump P for performing gas transfer operation of transmitting a gas into the ground side coil frame 102 or extracting a gas from the inside of the ground side coil frame 102; a pressure sensor 16 for detecting pressure inside the ground side coil frame 102; and a crack detection unit 15a for determining whether or not a crack exists on the ground side coil frame 102 from a variation in pressure detected by the pressure sensor 16 after gas transfer by the pump P.SELECTED DRAWING: Figure 1
