Laser positioning intelligent connection electric vehicle wireless charger and transceiver system

Abstract

The invention provides a laser positioning intelligent connection electric vehicle wireless charger and transceiver system which comprises an emitting part which is formed by a wireless charging cabinet (1), a positioning pole (2), an ultrasonic longitudinal positioning device (3), a laser transverse positioning device (4), an electric driving longitudinal movement positioning mechanism (5), an electric driving transverse movement positioning mechanism (6), an intelligent connection lifting and positioning device (7), a connection information integrated sensor (8), an induction launcher (9) and a sliding base (10). The system also comprises a receiving part which is formed by an induction receiving device (11), a digital positioning target (12), a rectifier and output power distribution unit (13) and an electric quantity display screen (14). The system is equipped with a laser automatic positioning and intelligent automatic connecting device, when a driver parks for wireless charging at a parking place, finding a wireless charging accurate position is not needed, only driving a vehicle to the parking plate as usual is needed, the highly efficient wireless charging can be realized, and the system has the advantages of worry saving and labor saving, high charging efficiency, and small high frequency leakage.

Description

technical field [0001] The invention relates to the application field of electric vehicle wireless charging technology, in particular to a laser positioning intelligent docking electric vehicle wireless charging transceiver system. Background technique [0002] Electric vehicle wireless charging technology has always been one of the high-end topics that the automotive industry in the world is committed to researching and solving. Japan, Europe and the United States have successively launched several new wireless charging products on the market in recent years, but so far, the wireless charging that is truly commercialized The product has never had a reliable report or become a practical and successful demonstration case. The reason is that there are many factors for the popularity of wireless charging products, but they are mainly summarized in the following aspects: First, the transfer efficiency of wireless charging products is low, and the loss Generally, the energy conve...

[0002] Electric vehicle wireless charging technology has always been one of the high-end topics that the automotive industry in the world is committed to researching and solving. Japan, Europe and the United States have successively launched several new wireless charging products on the market in recent years, but so far, the wireless charging that is truly commercialized The product has never had a reliable report or become a practical and successful demonstration case. The reason is that there are many factors for the popularity of wireless charging products, but they are mainly summarized in the following aspects: First, the transfer efficiency of wireless charging products is low, and the loss Generally, the energy conversion efficiency of the whole process is about 85%, which is nothing to be seen in low-power charging supplies, but the loss of 300w in the charging of 2000w electric vehicles is a kind of waste that is unacceptable to everyone, and the loss of electric energy is converted into A lot of heat has to be dissipated, which further increases power consumption; second, the existing electromagnetic induction charging technology requires the alignment of the transmitting and receiving coils to ensure charging efficiency, but in practical applications, it is difficult for drivers to align wireless charging at one time For transceiver devices, repeated corrections are definitely unacceptable, and the advantages of wireless charging are also lost; third, wireless charging is high-frequency radiation docking charging, which will inevitably cause high-frequency leakage, which is likely to cause interference to the surrounding environment. In summary, if If the above disadvantages cannot be solved perfectly, it will be difficult for wireless charging technology to be widely applied in real life
