Abstract

The invention discloses a wireless charging test bench for an electric vehicle. The test bench comprises a rack, an upper flat plate and a lower flat plate which are mounted on the rack. The lower flat plate is used for placing a transmitting coil; the upper flat plate is used for placing a receiving coil; and the lower flat plate and the upper flat plate are both made of non-metal insulating materials. The upper flat plate and the lower flat plate can be installed on the rack in a sliding mode in an X-axis direction, at least one of the upper flat plate and the lower flat plate can slide in aY-axis direction, at least one of the upper flat plate and the lower flat plate can ascend or descend in a Z-axis direction, and at least one of the upper flat plate and the lower flat plate can be installed on the rack in a rotating mode around the vertical center line. One of the upper flat plate and the lower flat plate deflects around the X axis, and the other one deflects around the Y axis.The test bench can be used for testing items such as electromagnetic field distribution and size, transmission distance, transmission efficiency and the like between the transmitting and receiving coils as well as testing relative spatial position changes and position alignment between the transmitting and receiving coils and is particularly suitable for testing a static or dynamic wireless systemof an electric vehicle.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging test bench for electric vehicles. Background technique [0002] Wireless charging has the characteristics of good safety, high degree of automation, no mechanical contact, and long service life of parts. It is one of the development directions of electric vehicle charging technology. The wireless charging method of electric vehicles uses magnetic coupling (electromagnetic induction or electromagnetic resonance) through the transmitting coil of the transmitting system and the receiving coil of the receiving system to realize the non-contact transmission of electric energy, thereby charging the power battery of the electric vehicle. In the development process of the electric vehicle wireless charging system, it is necessary to test the wireless charging system, collect relevant data during the charging process in real time, and process and analyze them...
