[YesAuto Electric Vehicle Technology] Today, when electric vehicles are still not widely used, many consumers who are accustomed to internal combustion engine vehicles still have certain doubts about the reliability of electric vehicles. Many people around me often ask: Is the battery safe? Will it leak? Is the structure reliable? Is the vehicle durable? …And so on. These questions actually show that everyone has a strong interest in whether electric vehicles are “resistant to build”, so today we will take a look at the “tests” that Denshi electric vehicles will pass before mass production.

When a prototype of an electric vehicle is designed, the test team will complete a series of test standards. Of course, these test standards are specified for the product characteristics after the vehicle development engineer has fully communicated, and they must also comply with the relevant standards. National standards and regulations. With these standards in place, the members of the testing team embarked on a long “verification journey.”

In the process of testing and verification, the testing team needs to go through a step-by-step verification process from components to systems, and finally to the entire vehicle. This is because it can save some “wrong roads”, lock the problem in a relatively small range, and ensure higher efficiency. However, what if every part and every system has passed the verification, and there are still problems in the vehicle test? Not to mention, this situation is not uncommon. Of course, the test team will not let every problem go. In their opinion, it is commonplace for them to overthrow everything.

Among the various tests, the one we are most familiar with is definitely the reliability and durability test of the whole vehicle. I believe that many of my friends have seen some test cars with varying degrees of camouflage “sweeping through the market” on the roads of their hometown, especially those areas with auto industry. However, what you have seen before is more of the complete vehicle test of traditional internal combustion engine models, and what are the links in the test of electric vehicles?

In addition to conducting road tests under natural conditions, electric vehicles will also undergo enhanced bad road tests at the test site. The test site has a variety of complex and harsh road conditions set up together, so the test intensity is higher, mainly for the structural durability of the chassis, body, internal and external components, and electrical related components of the vehicle. If you want to pass this test, Denshi Electric The car must reach a design mileage of 300,000 kilometers.

to sum up:

According to the test engineers of Tengshi, they used more than 100 test vehicles during the verification test phase, with a total mileage of more than 1.5 million kilometers, from the south to the north, from the east to the west, and experienced dryness and humidity, as well as high temperatures and cold . In this process, the test team localized the test system of Daimler-Benz in Germany, and at the same time mastered the test methods and procedures for electric vehicle products and domestic environmental characteristics. Back to the original topic: Are electric vehicles resistant to “built”? I think if an electric car has gone through and finally passed these “tests” before it came out, it should be trustworthy.
