The invention discloses a vehicle-mounted wireless power supply system and a vehicle-mounted system.The vehicle-mounted wireless power supply system comprises a first coil arranged on a vehicle-mounted chassis and a plurality of mutually independent electric energy transmitting units, and each electric energy transmitting unit comprises a power supply control device and a second coil; the length of the second coils in the vehicle-mounted driving direction is shorter than that of the first coils in the vehicle-mounted driving direction, so that the first coils cover the multiple second coils at any moment; the power supply control device takes power from a power grid power supply, generates high-frequency electric energy, transmits the high-frequency electric energy through the second coil when detecting that the vehicle is mounted on the vehicle, and closes the high-frequency electric energy when not detecting that the vehicle is mounted on the vehicle; the first coil and the second coil are respectively composed of a back-wound separated DD coil, and the difference between the intra-group distance of the DD coils and the height between the first coil and the second coil does not exceed a preset error, so that wireless power transmission with low leakage, high power efficiency, high stability of mutual inductance and high tolerance to coil faults on a line can be realized.
本发明公开了一种车载无线供电系统以及车载系统,该车载无线供电系统包括设置在车载底盘的第一线圈以及相互独立的多个电能发射单元,电能发射单元包括供电控制装置和第二线圈;第二线圈沿车载的行驶方向的长度短于第一线圈沿车载的行驶方向的长度且使得任意时刻第一线圈均覆盖多个第二线圈;供电控制装置从电网电源取电并产生高频电能,以及在检测到车载时通过所述第二线圈发射高频电能、未检测到车载时关闭高频电能;第一线圈和第二线圈均由反绕的分离式DD线圈构成,且DD线圈的组内间距与第一线圈和第二线圈的之间的高度的差值不超过预设误差,本发明可以实现低泄露、高功率效率、互感高稳定、对线路上的线圈故障容忍度高的无线电能传输。
