Application of wire harness tester in high-voltage wire harness detection of new energy vehicles
Foreword:
New energy vehicles have now become the choice of transportation for more people. They are clean and environmentally friendly, have better ride comfort, can carry more advanced technologies, and are more cost-effective than traditional cars.
High-voltage wiring harnesses are mostly used in new energy vehicles. It is a type of automotive wiring harness that can be configured to connect internal and external wiring harnesses of electric vehicles according to different voltage levels. It is the neural network of the high-voltage system of new energy vehicles and is very important.
In addition to having relatively high requirements on insulation performance and anti-electromagnetic interference performance, new energy vehicle high-voltage wiring harnesses also have the following characteristics:
high voltage
The national standard voltage of new energy vehicles is 200-750V, and the high-voltage voltage of pure electric vehicles is generally around 400V.
High Current
As the main energy transmission channel, the high-voltage wiring harness of new energy vehicles needs to withstand large currents, and the rated operating current of the DC bus can reach more than 300A.
safety
The voltage of the high-voltage wire harness can be as high as 250A based on the current carrying capacity of the high-voltage system components. The human body safety voltage is 36V, and the allowed current is 36mA. Once the safety of the wire harness does not meet the requirements, it may threaten human life. It can be seen that the safety of high-voltage wiring harness is very important.
Sealing
It is not difficult to see from the above analysis that for new energy vehicles, the performance and quality of high-voltage wire harnesses directly affect the performance and safety of the entire vehicle. Therefore, in order to ensure the quality of high-voltage wire harnesses, efficient and powerful wire testing is required Instruments assist.
