Description

A kind of wireless charging system for electric automobile
Technical field
The utility model is related to electric energy transmission technology field, more particularly to a kind of wireless charging system for electric automobile.
Background technology
Current electric automobile is in large-scale promotion period, and its charging modes is mainly charged using conduction-type, with convenient Property and security it is poor the problems such as.Electric automobile wireless charging technology based on wireless power transmission technology is arisen at the historic moment, but at present It is also immature, practical application is not obtained also.
Utility model content
The purpose of this utility model is to provide a kind of wireless charging system, can be applied to the wireless charging of electric automobile, The problems such as solving the convenience and poor security that conduction-type charging is present.
The utility model uses following technical scheme:
A kind of wireless charging system for electric automobile, including the ground surface end that is electrically connected with city and be installed on electric automobile and with electricity Vehicle-mounted end two parts of electrical automobile electrokinetic cell connection, it is characterised in that ground surface end includes Active PFC in sequential series Unit, high-frequency inversion unit, resonance compensation unit and transmitting coil, the Active PFC unit input and electric utility grid Connection;The vehicle-mounted end includes receiving coil in sequential series, resonance compensation unit, high-frequency rectification unit, the high-frequency rectification Unit output end is connected with electric automobile power battery.
Further, the resonance compensation unit uses LCC type impedance matching networks.
Further, the resonance compensation unit is made up of an inductance and two electric capacity.
Further, the transmitting coil is embedded in earth's surface, and the receiving coil is installed on electric automobile chassis.
Wireless charging system for electric automobile of the present utility model, can using electromagnetic coupled principle and resonance compensation technique Being wirelessly transferred for electric energy is expeditiously carried out, the existing convenience of existing electric vehicle conductive charging is solved and security is poor The problem of.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model wireless charging system for electric automobile.
Embodiment
As shown in figure 1, the utility model includes two parts of ground surface end and vehicle-mounted end:Ground surface end, including it is in sequential series Active PFC unit, high-frequency inversion unit, resonance compensation unit and transmitting coil, wherein Active PFC unit is defeated Enter end to be connected with electric utility grid;Vehicle-mounted end, includes receiving coil, resonance compensation unit and the high-frequency rectification unit of series connection, wherein The output end of high-frequency rectification unit and the electrokinetic cell of electric automobile are connected.
During charging, the power current of civil power carries out rectification by Active PFC unit and Active PFC becomes 400V or so direct current, while ensuring that power factor is more than more than 95%;Then direct current passes through high-frequency inversion cell translation For high-frequency alternating current, and the best match between transmitting coil is realized after resonance compensation unit, into the height of transmitting coil Frequency alternating current is converted to alternating electromagnetic field;Receiving terminal is by the receiving coil with transmitting coil electromagnetic coupled in alternating electromagnetic field High-frequency alternating current is induced, receiving coil and high-frequency rectification unit and electrokinetic cell are then realized most by resonance compensation unit Good matching, and AC conversion is that direct current is power battery charging.
