Problems solved by technology

At present, electric vehicles have problems such as easy to cause battery pollution, poor battery life, and long single charging time, which consume a lot of time in the charging process, and there are certain safety hazards in the charging process
[0003] With the gradual popularization of wireless charging standards, two major industrial chains have been formed, the transmitting end and the receiving end. The wireless charging industry is booming. However, in terms of current testing, due to the high frequency of wireless charging, for example, 85kHz is generally used in car wireless charging. Therefore, the difficulty of the test lies in the power consumption and efficiency test. Generally, it is required to test the efficiency of the DC-DC terminal and the AC-AC efficiency of the transmitter and receiver. The DC-DC terminal is easy to test, but the difficulty lies in the efficiency test of the AC-AC terminal.
At present, according to the standard manual measurement of the place where the coil is located, the accuracy of position calibration is poor, the reproducibility of measurement is low, and the work efficiency of manual measurement is not high. There is no complete test and detection plan for dynamic wireless charging system testing, and Not very versatile
