Abstract

The invention discloses an inductive non-contact charging device with a precise centering function for an electric automobile. The inductive non-contact charging device comprises an electric energy transmitting terminal and an electric energy receiving terminal. The electric energy transmitting terminal enables an electric energy transmitting coil to generate a high-frequency alternating magnetic field through a PWM rectifying circuit and a high-frequency inverter circuit and sends the energy to an electric energy receiving coil, arranged on the automobile, in the electric energy receiving terminal. The power battery is charged through the rectifying circuit and a step-down circuit. Meanwhile, after center position information of the electric energy transmitting coil and center position information of the electric energy receiving coil are acquired and compared, the position of the electric energy transmitting coil is adjusted and centering between the electric energy transmitting coil and the electric energy receiving coil is achieved. The inductive non-contact charging device has the advantages that electric energy transmitting can be conducted efficiently, meanwhile, precise centering of the electric energy transmission coils at the two sides is conducted after the electric automobile stops completely by the adoption of a mechanical transmission device, and electric energy transmission efficiency is further improved.

Description

technical field [0001] The invention belongs to the field of new energy vehicle engineering and relates to a non-contact charging device, in particular to an inductive non-contact charging device with a precise centering function for an electric vehicle. Background technique [0002] When electric vehicles adopt the traditional wire charging method, the live conductors are exposed, which is prone to sparks, poor contact, electric shock and other accidents, bringing safety hazards to users. In severe weather conditions such as rain and snow, it is not suitable to use wire contact charging, which will affect the outdoor charging and normal operation of public vehicles such as electric buses and sanitation vehicles. In addition, electric vehicles that are used around the clock in special environments, such as electric airport shuttle buses, also face charging difficulties in rainy and snowy weather. [0003] For electric vehicles, large-capacity batteries must be used in order...
