Is it easy for new energy vehicles to catch fire? Earlier, some well-known experts angrily accused a small number of media outlets who do not know the truth for distorting the data and ignoring the facts. Obviously, the risk of spontaneous combustion of new energy vehicles is much lower than that of fuel vehicles. However, just after only a month, the temperature has just risen, and there have been many new energy vehicle fires in China.
Recently, an incident involving a fire on a highway involving a commercial vehicle of Wenjie Automobile has aroused widespread public concern. According to the video circulating on the Internet, a transport vehicle carrying the AITO brand series SUV caught fire in the Hubei Caidian section of the G50 Shanghai-Chongqing Expressway, and the fire was fierce, resulting in almost all the damage to the transport vehicle and the passenger vehicle on board.
After the incident, Wenjie automobile manufacturer Cialis Automobile Company and Anji Logistics, which carried the vehicles, responded quickly. According to Celis Automobile, the cause of the fire was preliminarily determined to be the locking of the brake system of the transport vehicle, which caused a fire on the rear wheels of the vehicle, and the fire spread and caused damage to the loaded commercial vehicle. Sailis Auto also pointed out that through the background data query, the battery pack data of the commercial vehicle on the truck was normal, which ruled out the possibility of fire caused by the commercial vehicle's own problems.
From the pictures at the scene of the accident, we can see that the logistics vehicle has obvious roll, and the possibility that the tire will burn before the commercial vehicle does exist.
However, for the specific reason for the locking of the brake system of the transport vehicle, neither Cialis Automobile nor Anji Logistics gave a detailed explanation. However, according to the general knowledge of the automotive industry, drum brakes (drum brakes) can overheat during prolonged braking or in high temperature environments, resulting in weakened or even malfunctioning braking force. Due to its relatively sealed structure, the heat energy generated by the drum brake is difficult to dissipate in time, and the brake may lock up due to ultra-high temperature. In addition, brake drum failure, brake cylinder failure, or brake master cylinder failure can also be the cause of locking.
According to reports, the damaged models mainly include the M9 and M5, which have high recognition and market popularity in the domestic auto market. Although the fire incident may have a certain impact on consumer confidence, the timely response of Celis Automobile and Anji Logistics can help control the trend of public opinion and reduce the adverse impact on the brand image.
However, some netizens questioned that the country is not in high temperature weather in May, and from the analysis of the photos, the place where the incident occurred is not in a long downhill section, and the possibility of long-distance braking of logistics vehicles is not large. At the same time, although the M9 and M5 belong to the new energy SUV, they use a plug-in structure, the weight of the body is not outstanding, the total weight of 8 commercial vehicles will not exceed 20 tons, which is a relatively light cargo for logistics vehicles, and the working pressure of the brake system is not large, and the problem of brake overheating is relatively rare. After the official announcement, the fire department involved in the rescue at the scene has not yet given an accident report.
There is a text that says:
Compared with the recent Wenjie M7 rear-end collision and fire on the highway evolved into a one-sided public opinion crisis, the official response to the Wenjie automobile commercial vehicle fire incident was swift, and the cause of the fire was attributed to the failure of the transport vehicle. This incident reminds all car manufacturers and logistics companies that it is necessary to strengthen the maintenance and inspection of transport vehicles to ensure safe transportation and protect the interests of consumers. At the same time, we also hope that Wenjie Auto can learn lessons from this incident, further improve product quality and service levels, and provide consumers with safer and more reliable automotive products."
