Recently, the automobile media platform “Understanding the Car” released a collision test video of the BYD Han EV and BAIC Polar Fox Alpha S head-on collision. This time the two cars were used for a 50% offset collision at a speed of 64km/h. Way.But what attracted the most attention was not the result of the test itself, but after the vehicle was left standing for 48 hours after the test, the BYD Han EV suddenly burst into flames.
In response to this matter, BYD officials also responded for the first time, saying: The coolant of the collision vehicle in the video (red, commonly used in the industry, conductive) and the coolant of the Han EV production car (purple, unique to BYD) , Non-conductive) is completely different. After the collision vehicle is replaced with a conductive coolant, the vehicle coolant leaks within a few days after a severe collision, which causes a short circuit of the circuit and triggers combustion.
In addition, BYD officials also emphasized that the test standards and methods used in the video are non-mainstream, non-authoritative, and not national and industry standards.
According to BYD, the current commonly used coolant in the industry is red and conductive, while the Han EV production car uses BYD’s unique purple coolant, which is non-conductive. This response triggered a wave of car owners scrambling to check the “coolant color”.
On July 27, according to a report from Tencent Auto, the relevant person in charge of BYD stated to him, “Han EV has different colors of coolant according to different batches, but only the color of the filling is different. The coolant is non-conductive, which has nothing to do with the color .”
In other words, car owners no longer have to open the front door to see the color of the coolant. Regardless of the color, the mass-produced version of Han EV coolant is “non-conductive”.
At present, BYD has communicated with the media on the matter and will arrange for on-site inspections and doubtful investigations by technical personnel.
