AutoBeta(AutoBeta.net)09/14 Report--

In response to a sudden incident that occurred at the Lutai Auto Show in Weifang a few days ago, a smoking accident occurred at a BYD booth. The local BYD 4S store replied that the smoke was caused by a third party to charge the battery improperly and had nothing to do with the car.

The incident occurred on the official opening day of the 14th China Weifang Lutai International Auto Show in 2019, a BYD fuel version of the nameplate Song MAX. The video shows smoke in the engine cabin of the car, but there is no open fire, and the booth staff are looking for the cause of the problem. However, the problem was discovered in time and did not cause serious consequences.

In this regard, Weifang Jin Maosheng BYD 4S store staff said that the smoke was caused by improper charging operation of third-party companies. "an external plug connects two wires, and the two external wires are unstable because of voltage, and then the wires cause melting and smoke. The cable connected to the frequency from the plug is a random piece of wire found by a third-party company, which is softened and causes smoke. "

However, compared with the occurrence of smoke from new energy vehicles, the occurrence of smoke from fuel vehicles is also relatively rare at present. The development time of new energy vehicles is relatively short, and the safety issue has also attracted much attention. Moreover, the main reason for the spontaneous combustion of many new energy vehicles is that they are equipped with ternary lithium batteries, just like carrying this giant portable battery out of the door. Lithium is a very active metal and extremely unstable. Batteries containing lithium or portable battery are easy to produce high temperatures and sparks in friction collisions, and it is also easy to cause spontaneous combustion in case of heat.

In fact, new energy vehicles are more likely to self-ignite than traditional fuel-fired vehicles. The spontaneous combustion factor of the new energy vehicle is higher than that of the traditional vehicle, because the new energy vehicle increases the proportion of electricity consumption of the whole vehicle, and the electric energy not only makes the automobile related electrical appliances work, but also drives the vehicle forward, that is, the electrification degree of the new energy vehicle is higher. This increases the electrical complexity of the vehicle, which contains a higher risk coefficient of spontaneous combustion, which is the attribute of the new energy vehicle itself.

Many external factors of spontaneous combustion of new energy vehicles do not do much harm to fuel vehicles, and the possibility of causing spontaneous combustion is very small. And because of the complexity of its internal structure, the possibility of combustion of the power battery is also higher than that of the fuel vehicle.

In any case, as long as there are any problems with the vehicle, whether it is human misoperation or vehicle quality problems, it needs to be treated with caution, and ensuring safety is the most fundamental problem.
