AutoBeta(AutoBeta.net)07/25 Report--

On July 24, Byte Jump's automotive media platform "understanding car Emperor" released a video of a head-on collision between BYD EV and BAIC polar fox Alpha S. unlike previous collision standards, the media adopted the 50% offset collision standard of two-car 64km/h. In other words, during the collision test, Biadihan EV and polar fox alpha S both collided head-on at the speed of 64km/h and 50% overlap rate (driver side), and then evaluated according to the degree of deformation of the car body and dummy injury data.

The models tested in this time are 2020 super-long-lasting deluxe models with no head air curtain, which are priced at 229800 yuan for BYD Han EV, and 2021 525S models priced at 251900 yuan for polar fox Alpha S. By comparison, the two models are medium and large cars, but BYD's vehicle weight and body wheelbase, length are better than the polar fox Alpha S. In terms of active / passive safety, the BYD EV is standard with primary / passenger seat airbags, front / rear side airbags, front / rear head airbags (air curtains), knee airbags, while the polar fox Alpha S lacks rear side airbags and knee airbags.

From the data point of view, BYD Han EV all kinds of data are better than the polar fox Alpha S, that is to say, BYD Han EV still has some advantages, but from the collision results, BYD Han EV "lost". From the test, the roof of the polar fox Alpha S is still very intact after the collision, there is no obvious deformation and damage, and the A-pillar is not obviously bent. Compared with the Biadihan EV, the front cabin position collapse is very serious, the anti-collision beam is broken, the A-pillar is also obviously deformed, the car door is not unlocked after the collision, the emergency flasher is not opened (low-voltage system power is off), and it is not only the main driver position, but also the co-pilot position is deformed. According to the host, BYD Han EV is absorbing energy all over the body.

From the dummy data, the protection of the two cars to the driver is OK, although the BYD EV does more damage to the driver's head, but within the safety range, the BYD Han EV is not ideal for the driver's leg protection, but the two cars are not very optimistic about the protection of the rear passengers.

Some netizens believe that BYD Han EV collision polar fox Alpha S is not in line with expectations, mainly because the body rigidity and structural design of BYD Han EV is not as good as that of polar fox Alpha S, the latter is made jointly by ARCFOX extreme fox and Magna, and there are few models with mixed steel and aluminum body on the market, so it is normal for BYD Han EV collision to be inferior to polar fox Alpha S.

Finally, let's take a look at the fire. The two models did not catch fire and explode during the collision, but after 48 hours of static after the collision, the BYD EV suddenly burst into smoke and caught fire, and finally the whole car was destroyed. According to the host, the fire brigade determined that the electrical circuit failure caused the fire.

For the case of BYD Han EV fire, some netizens think that it has something to do with polar fox alpha S, because of the advantages of polar fox alpha S body structure, BYD Han EV has certain disadvantages in the collision, its battery package should be greatly deformed, and the blade battery is damaged resulting in fire.

In view of the situation that BYD Han EV caught fire after the collision. BYD's official statement said: the coolant of the collision vehicle in the video (red, widely used in the industry, conductive) is completely different from that of the Han EV production car (purple, unique to BYD, non-conductive). After the collision vehicle is replaced with a conductive coolant, the coolant leaks within days of a severe collision, causing the circuit to short circuit and cause combustion. In addition, BYD officials also stressed that the testing standards and methods used in the video are non-mainstream, non-authoritative, and not national or industry standards. We welcome the media to adopt innovative testing standards and methods, but we hope that the media can communicate and discuss with enterprises in advance before the test, so that the personalized design differences of different models can be fully taken into account in the test. so as to ensure that the test results are more objective and reasonable. At the same time, for over-interpretation and malicious extension of the media, reserve the right to pursue their legal responsibility!

Of course, an impact test can only be used as a reference, not a complete conclusion. Prior to this, China Insurance Research Institute and China Automobile Research Institute have conducted collision tests compared to Yadihan EV. In the collision test of China Insurance Research Institute, the occupant safety index, pedestrian safety index and vehicle auxiliary safety index are all G (excellent). In the frontal 25% offset collision, the occupant cabin invasion and dummy injury of BYD EV are all good, and the A-pillar is not obviously deformed. In the China Automobile Research collision, the comprehensive score rate of BYD EV was 91.5%, and the A-column was not significantly deformed in the 40% frontal offset collision.

For understanding the car emperor collision test, some netizens believe that "BYD Han EV still has some room for optimization, for example, in the car body structure, there are still some deficiencies in vehicle safety, which need to be improved and perfected by car companies." Some netizens also believe that, "there is the possibility of tampering with tests without any third-party supervision, and the results do not have credibility." What do you think of the test of BYD Han EV colliding with polar fox Alpha S released by car Emperor? You are welcome to leave a message for discussion in the comments section.
