After the man Deng went to the factory to learn the principle, he went home and used the collected waste battery module to transform it into an electric bicycle battery, claiming that one piece could run more than 200 to 300 kilometers. A few days ago, Deng and others were seized by the police. When the police conducted an electric test on the battery they had transformed, the three batteries "bloomed" one after another, and all of them burst into flames.
The 10-square-meter rental house hides a den of illegally assembled and modified electric vehicle batteries, and the suspect is full of fire extinguishers next to the bed, saying "I'm also afraid"
It is understood that the police of Beijing Fengtaihuan Food and Drug Brigade found that some people posted content related to the production of illegal electric bicycle batteries on the Internet and sold them.
On April 26, the special police arrested the suspects Deng and Du in a rented house in an old community, and seized 5 fake and shoddy batteries, as well as materials and tools. The whole battery transformation and production process is carried out in the room where Du lives, the whole room is only about 10 square meters, dim and cramped, in addition to battery components, tools, there are five or six fire extinguishers next to the bed. And Deng's family is old and young, but they live next door to the small workshop.
According to Deng's confession, he and Du have a "master-apprentice" relationship, and they are responsible for production on weekdays, while Du is mainly responsible for sales and delivery. As for the reason why there are fire extinguishers in the small workshop, Deng said, "I am also afraid of fire. ”
Discover new "business opportunities" to dare to build batteries after two days of learning in the factory Support customized services
It is understood that Deng came to a small factory in the south to learn the installation process of the battery. Through online learning and factory practice, Deng only took two days to figure out the production and assembly principle of electric bicycle batteries. He returned to Beijing and opened his own small workshop.
Deng simply connected and assembled the purchased waste battery modules, and sealed them in an iron box, which became a large battery weighing more than 40 kilograms. Du constantly publishes advertisements and relies on word of mouth from customers to develop business.
A reporter from Beiqing Daily learned that in order to cope with the inspection, Deng also made and purchased a batch of qualified logos and safety tips online, which were pasted on the outer packaging of the battery. In addition, it also supports the customization service of batteries, which can make batteries of different sizes according to different models of vehicles, and even includes the service of helping to modify the battery compartment of electric bicycles, which are sold at prices ranging from 4,000 yuan to 8,000 yuan per piece.
The police seized 5 counterfeit and shoddy batteries from the scene. In addition, through further work, the Beijing Fengtai police locked up Liang, the "upper family" of Deng and Du, who purchased waste new energy batteries.
Then, with the vigorous assistance of the provincial public security and market supervision departments, the Beijing Fengtai police arrested the suspect Liang, and seized 20 fake and shoddy batteries, more than 1,000 raw material cells, and a number of electrical appliances, parts, and testing instruments used in assembling batteries.
After review, Liang truthfully confessed the illegal and criminal facts of illegally assembling and selling fake and shoddy electric bicycle batteries by purchasing waste new energy battery cell components or second-hand batteries.
The 3 assembled and modified batteries were sent to a third-party organization for testing, and all of them caught fire
A reporter from Beiqing Daily learned that in order to determine whether the specific data of illegal assembly and sales of shoddy electric bicycle batteries exceeded the legal standards for electric bicycle batteries, the police sent 3 of the batteries to a third-party organization for testing and experiments.
On May 9, 10 and 11, the testing agency tested the three batteries in three times.
On the 9th, the first battery swelled in the process of standing after charging, and then burst into flames, and then fell into the explosion-proof box below.
On the 10th, the second battery suddenly cracked during the test, and the internal cells and components continued to stretch and "bloom", and after a crackling sound, the battery burst into flames, and thick smoke immediately filled the house.
On the 11th, when the testing agency tested the third battery, the battery first emitted smoke, and in less than 5 seconds, it directly ignited, and continued to burn in the explosion-proof box for nearly 3 minutes.
Deng then confessed that his own technology could not guarantee the waterproof sealing of the battery. He estimates that in addition to charging overnight, these batteries are also very prone to fire as long as they come into contact with water.
At present, the three people have been criminally detained by the Fengtai Public Security Bureau in accordance with the law, and the case is being further tried.
The police reminded that illegally modified electric bicycles have potential safety hazards such as wiring damage, short circuit and spontaneous combustion. Illegal modification of electric vehicles harms others and themselves, and the majority of drivers must stay away from modified cars. When buying an electric bicycle, you should choose a regular brand.
