Problems solved by technology

[0002] At present, with the increase in the use of various types of electric vehicles, strict requirements have been put forward for the safety and reliability of electric vehicles. The equipment and the motor equipment work together to realize the normal operation of the electric vehicle, which will cause the electric vehicle's own circuit system to malfunction during the operation of the electric vehicle, as well as the electromagnetic interference generated by its own electrical equipment and the electrical equipment of the external environment, resulting in The vehicle cannot run normally, and in severe cases, it may even lead to a sudden loss of control of the electric vehicle circuit system, which seriously affects the safety and reliability of the electric vehicle operation. Therefore, in response to this problem, it is urgent to develop a professional electric vehicle electromagnetic interference detection methods to meet the needs of practical use

Embodiment 1

[0019] Such as figure 1 A novel new energy vehicle body electronic electromagnetic compatibility test method is shown, including the following steps:

[0020] The first step is basic information collection. First, obtain the internal circuit structure layout of the vehicle to be tested, the distribution position of electrical components, operating parameters, and the connection and positioning relationship with the vehicle body, and then obtain the external electromagnetic environment parameters of the vehicle under the actual operating state of the vehicle to be tested;

[0021] The second step is to locate the vehicle to be tested, park the vehicle to be tested on the vehicle test platform, and perform positioning, and then seal the periphery of the vehicle to be tested so that the vehicle to be tested is in a closed environment;

[0022] The third step is self-electromagnetic compatibility testing. After completing the second step, the temperature of the closed testing envi...
