Nowadays, the development momentum of new energy vehicles has been very rapid, and people’s focus on new energy vehicles has gradually changed from configuration and endurance to safety. Of course, the more important thing is the safety and stability of the battery, but many people will ignore one thing, that is, the battery and the electronic equipment of the vehicle will have electromagnetic radiation.

So how can we achieve lower radiation and avoid external radiation from coming into the car? With this question, we came to the Pan-Asian Electromagnetic Compatibility Laboratory in Shanghai today to see what tests Buick GL8 Luzun PHEV has experienced here, so that the electromagnetic radiation of vehicles is lower than that of mobile phones.

First of all, we should know the harm of excessive electromagnetic radiation. If the radiation is too large, it may cause the function failure or misoperation of electronic equipment or its surroundings, or even burn or breakdown components, which will have a serious impact on our daily life and the safe driving of vehicles. If the anti-interference of the vehicle itself is insufficient, there will also be great safety hazards during the driving process.

In daily life, the following situations often occur, which have different degrees of electromagnetic radiation effects on vehicles or passengers, such as abnormal interference from the outside of the power grid when charging, the influence of electromagnetic radiation inside the vehicle on the equipment inside and outside the vehicle, the external electromagnetic interference of vehicle electrical appliances, the influence of electromagnetic radiation generated by various working conditions of the vehicle on people, and the damage of human static electricity to electronic devices inside the vehicle. So let’s simulate several common situations today to see how GL8 Luzun PHEV responds.
High voltage charging immunity test
This test is to measure all kinds of anti-interference tests under charging conditions, and inject all kinds of interference waveforms into the test vehicle through the testing equipment to check whether the vehicle design can resist these interferences. Although the national standard of this test item is not mandatory at present, it is a must-do item on Buick GL8 Luzun PHEV, and the overall performance should be at the leading level in the industry, so as to ensure that the vehicle will not cause adverse effects on the power grid and surrounding electrical equipment when charging, and when abnormal voltage fluctuation and surge current occur in the power grid, it will not cause adverse effects on charging vehicles connected to this power grid.

Electromagnetic radiation disturbance test
The purpose of this test is to detect the electromagnetic radiation emitted by the electronic system on the car when it is working, such as the screen, sound system, screen and lighting on the car. The national standard of this project has fixed the left and right directions, but Buick GL8 Luzun PHEV has added the front and back directions in addition to the left and right directions to ensure that the vehicle radiation does not interfere with the electronic parts in the car.

Electromagnetic radiation immunity test
This test is to test whether the working state of all electrical appliances on the vehicle is disturbed by signals of different super-large antennas with different shapes, different frequency bands and different intensities under normal driving conditions. For example, when passing around the airport, TV tower, broadcast signal tower, tunnel entrance and other areas, the electromagnetic signal will change very obviously. The national standard for testing only specifies one direction, and the field strength is 30V/m, while Buick GL8 Luzun PHEV tests four directions, and the field strength is increased to 100V/m to simulate a more realistic use scenario, so as to ensure that the vehicles driven by passengers can drive safely in areas equipped with various electronic equipment.

Electrostatic discharge test
In the test room with temperature and humidity control, the calibrated electrostatic gun is used to test the electrostatic discharge of all the places that passengers can touch inside and outside the car, such as door handles, operation panels, display screens and buttons, so as to test that all the parts that passengers can touch can withstand harsh electrostatic influence. The test will gradually increase from the low voltage level to carry out electrostatic discharge test, and the voltage will gradually increase from 1kV to the highest 25kV according to different discharge conditions in different locations, so as to ensure that customers’ vehicles should not be damaged by static electricity in autumn and winter.

Human magnetic field exposure test
Pan Asia was first introduced into the domestic automobile industry. Since 2010, it has been studying the impact of electromagnetic radiation on human health and safety. Since 2012, it has improved the global standard of GM and started relevant tests. Pan Asia not only carries out the international standard ICNIRP test, but also carries out the domestic mainstream C-GCAP and CAHI tests, and the test standards are more stringent, which not only tests the instantaneous peak value of electromagnetism, but also pays more attention to the long-term cumulative impact on the human body.

The test covers the magnetic field radiation values under different working conditions, such as stationary, uniform driving, acceleration, deceleration, charging, etc. Buick GL8 Luzun PHEV will pass three evaluation standards of international and domestic double standards to ensure the electromagnetic safety of the area where passengers sit or the parts of the vehicle that will touch under any working conditions.

Summary:
Electromagnetic radiation is an invisible hidden threat. Although new energy vehicles will also carry out some tests and experiments on this project at present, as consumers, wouldn’t the lower these threats be, the better? What Buick GL8 Luzun PHEV has done in this regard is very in place. After all, it is a leader in the MPV market, so its excellent performance will also bring new industry standards in the field of electromagnetic safety.
