Abstract

The invention discloses an electric vehicle dynamic wireless charging module and a parallel connection method thereof, and relates to the field of electric vehicle wireless charging. The electric vehicle dynamic wireless charging module is provided aiming at the technical problem that dynamic charging output power of an existing electric vehicle cannot be automatically matched according to the vehicle electricity amount, and only monotonous power can be output. An alternating-current input and protection unit, a filter, a power conversion module, a transmitting terminal resonance circuit, a power conversion module control unit, a sampling unit and a current-sharing control unit are organically combined, wherein the power conversion module is formed through parallel connection of multiple power conversion module bodies, modularized design is adopted for the power conversion module, the power output level is adjustable, the capacity-expanding capability is high, and the electric vehicledynamic wireless charging module has the advantages of an electric vehicle dynamic wireless power supply power converter of being efficient, and high in power and density, is applicable to dynamic wireless charging of multiple electric vehicles of different model numbers, and the module and the parallel connection method are simple and reliable, high in stability and wide in applicability.

Description

technical field [0001] The invention relates to the field of electric vehicle wireless charging, in particular to an electric vehicle dynamic wireless charging module and a parallel connection method thereof. Background technique [0002] As one of the hot spots in the global automotive field, the research and development of electric vehicles is becoming more and more mature, and the related technical difficulties, including electric drive, coordinated control, energy management and vehicle integration, have been greatly improved. At present, fixed-point wireless charging technology for electric vehicles solves the potential safety hazards of wired charging piles (such as contact ignition, cable burning, forgetting to unplug the plug to start the electric vehicle, etc.), poor climate adaptability, need to have exposed parts, poor flexibility and convenience, etc. The problem is a qualitative leap in the parking charging technology of electric vehicles. However, power supply...
