Abstract

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.

Description

technical field [0001] The invention relates to the technical field of on-board wireless charging, in particular to a on-board wireless power supply system and a on-board system. Background technique [0002] During the driving process of the vehicle, dynamic wireless energy transmission can be carried out by means of magnetic field coupling. Specifically, it is necessary to embed a transmitting coil on the road, set a receiving coil at the bottom of the vehicle, and transmit the power transmission coil in the form of magnetic field radiation, and the vehicle receives the magnetic field radiation through the receiving coil to obtain electric energy. [0003] refer to figure 1 , The commonly used coil configurations for wireless charging include a flat circle, a flat rectangle, and two rectangles in series (ie, DD type). These structures can be divided into two categories, single coil and multi-coil. The use of a single coil to wirelessly transmit electric energy has the p...
