Abstract

The invention discloses a measuring system and method for electromagnetic field distribution in wireless charging of an electric vehicle. The measuring system comprises an electric vehicle, a wirelesscharging receiving device, a wireless charging transmitting device and an automatic testing device. A testing rod includes an X-axis crossbar, a Y-axis standing column and a Z-axis rail; since the X-axis crossbar can move freely at the Y-axis standing column and the Y-axis standing column can move freely on the Z-axis rail, the magnetic field distribution situation of each point around the electric vehicle in charging can be measured automatically by the automatic testing device, so that a detection result is obtained rapidly; the detection result is clearer and more accurate; the detection result can be displayed for the user visually by the formed three-dimensional image; and thus the user can perfect the control strategy based on the e magnetic field intensity distribute situation.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a measurement system and method for electromagnetic field distribution during wireless charging of electric vehicles. Background technique [0002] With the continuous promotion of new energy vehicles, especially electric vehicles or hybrid vehicles, new energy vehicles have become increasingly relevant to our daily life. At present, the charging method of electric vehicles is mainly a wired charging method, but there are many shortcomings in the conventional wired charging method, and the wireless charging method can make up for these shortcomings. At present, wireless charging has begun to be applied in some low-power charging fields, such as mobile phone charging. However, the high-power wireless charging equipment used for charging electric vehicles is still in its infancy, and there are still many shortcomings, such as fewer system detection functions, imperf...
