Note: The safety of electric vehicles to replace high-power battery packs

Since Nanchang’s “ban on motorcycles”, many citizens have chosen electric vehicles as a means of transportation. However, the reporter found that some merchants have replaced the high-power battery packs for electric vehicles in order to meet the needs of customers, in order to increase the speed of electric vehicles. The modified electric vehicle not only has a traffic accident due to the excessive speed, but also has a hidden danger of spontaneous combustion of the vehicle.

Powerful modified car speed up to 60 yards

A few days ago, according to the reflection of Mr. Wang, the electric vehicles that have been modified can be seen everywhere in Nanchang. The horsepower is very high and the speed is very fast. It has been observed that these vehicles are equipped with high-power batteries, and the modified speed can be comparable to that of motorcycles. Then Mr. Wang introduced a kind of electric car called "Long Run King" to the reporter. The appearance of the car looks no different from that of an ordinary electric car, but when you ride it and gently twist the accelerator, the speed will drop to 30 or 40 yards. If you turn the accelerator to the end, the speed can quickly reach 60 yards or more. The reporter also found that the load of this kind of car is very large. In addition to carrying two people, it can carry more than ten kilograms of items, and the power comes from the "secret" in the battery box.

The accident probability is high, the vehicle is easy to spontaneously ignite

According to the police officer Xu Yonghua of the Red Valley Beach Traffic Police Brigade, the modified battery car does exist. The owners are mostly students, young people, "electric motorcycle" drivers and logistics distributors. Such a car has a "missing fish" in daily investigations. The reason is that non-professionals only find it difficult to find out whether there is a problem from the appearance of the vehicle. The routine inspection can only be based on checking whether the electric license plate is complete. "The modified car is very easy to accident. For example, the speed of the modified car is increased, the inertia of the car is increased, and the brakes are suddenly braked. It is very likely that people are thrown out." According to the statistics of the traffic control department, the proportion of accidents of such vehicles is the largest among similar models.

The staff of the city fire detachment said that the high-power battery pack replaced by the modified car would cause the current of the internal circuit of the electric vehicle to be too large. If the power of the motor does not match, the excessive heat generated will be easily ignited, resulting in the electric vehicle. Self-ignition.

"Single soldier combat"

According to the relevant regulations, electric vehicles are limited-speed devices when they leave the factory, otherwise they will not pass the quality supervision and audit; in the sales process, the industrial and commercial departments will investigate and deal with counterfeit and shoddy vehicles with incomplete licenses; if the purchase is completed, if the vehicles are not licensed, they will be checked by the traffic police. buckle. However, in the daily law enforcement, individual businesses have thoroughly understood the various inspection and correction processes, and often close the door when they are inspected. Sometimes it is difficult to lay out evidence in plain clothes.

In this regard, some transportation experts suggested that the annual inspection system for electric vehicles should be promoted, and the over-standard vehicles suspected of decks should be seized. At the same time, it is suggested that the current single law enforcement should be changed to multi-sector linkage, and this hurricane will be completely curbed through centralized rectification and regular joint inspections.
