We have developed a 44kW wireless charging system for electric buses, which achieves a reduction in radiated electromagnetic emissions by devising structure alignment. The receive output power of 44 kW or more was confirmed by test verification. And even if the misalignment of charging pads occurs, system efficiency exceeds 85%. Moreover we have conducted verification operation tests using electric buses running on public roads. The tests have verified that these wireless charging systems offer enhanced convenience and achieve the targeted power transmission efficiency.
