The self-combusting electric vehicle is the owner of the second-hand car purchased online and the battery modified by himself
Quanzhou Net, June 26 (Financial Media Reporter Fu Heng Correspondent Huang Alan Text/Picture) Electric bicycles are an indispensable means of transportation in the daily lives of citizens and friends, but there is such a type of electric bicycle on the market, like a time bomb, it may endanger your life when it is a modified electric vehicle. A few days ago, in Yongchun, a modified electric car spontaneously combusted while driving, but fortunately it did not cause a tragedy. According to the reporter's investigation, the situation of unauthorized modification of electric vehicles is not an exception, and more than 10 electric vehicle fires have occurred in Quanzhou in less than a month recently, many of which are related to battery failure. The fire department reminds that in addition to the fire hazard of modified electric vehicles, there are also many traffic safety hazards, so do not take risks.
Spontaneous combustion of electric vehicles while driving It turns out that the battery is modified
Recently, near Zhongmin Parkway Shopping Mall on Taoyuan South Road, Yongchun County, an electric bicycle suddenly caught fire while driving. After receiving the alarm, firefighters immediately went to the scene to deal with it. At that time, smoke was billowing from under the pedals of the vehicle, and the firefighters immediately evacuated the onlookers to extinguish the fire, and the fire was quickly and effectively controlled.

A fire broke out in an electric vehicle battery
In less than a month, there were more than 10 fires, many of which were caused by battery failures
The reporter learned that as the weather is getting hotter, in less than a month, more than 10 electric bicycle fires have occurred in Quanzhou, many of which are related to battery failure.
On June 21, an electric bicycle on Yunfeng Road, Beifeng Street, Fengze District, suddenly caught fire during charging.
On June 14, a low-speed electric bicycle caught fire on Pontoon Street, Jinlong Street, Licheng District.
On June 10, an electric bicycle on Chenghua North Road, Huada Street, Fengze District, suddenly caught fire while driving.
On June 3, an electric bicycle on West Ring Road in Lingxiu Town, Shishi City caught fire.
On June 1, a lithium battery for an electric bicycle caught fire near Yashan Building, Beifeng Street, Fengze District.
After investigation, except for the first one, the above five fires were caused by battery failure.
The Internet is full of electric vehicle modification "tutorials"
The Internet is full of modified car tutorials Some netizens are keen on online shopping and changing cars
"Explosion change electric donkey, zero hundred acceleration in less than three seconds, the top speed can reach 100+" "The latest arrival of the small change No. 9, is it your dish" "For modified accessories, which must be on" "How to speed up the electric car, where to change"......
The reporter searched for "electric vehicle modification" on a short video platform, and many "tutorials" for modifying electric vehicles jumped out. Some netizens will "proudly" post videos of themselves modifying electric vehicles at home on their accounts to share their modification "experience". The number of likes on these videos ranges from thousands to tens of thousands, and in the comments below, many netizens are consulting the details of the modification, and some people are asking about the price of the modified car, saying that they want to buy it directly, but few people question the safety hazards of the modified car.
The reporter searched for keywords such as "electric bicycle" and "modification" on a social platform, and among the top results, there were also promotional pictures and texts of a number of accessories modification shops, saying that they could provide speed limit cracking and accessory modification services for multi-brand vehicles.
The reporter learned that many young people will choose to buy modified electric vehicles online, and the modified cars purchased online lack of supervision, which is prone to quality problems and has a lot of potential safety hazards.
Merchant Retrofitting the battery is risky and can even cause an explosion
Mr. Huang, who has been operating electric vehicles in Quanzhou for 15 years, told reporters that in addition to modifying the appearance, the interior of the modified electric vehicle is either a modified battery or a modified motor. Delivery riders are the main group of people who modify the battery, they feel that the vehicle does not have enough battery life and modify the battery, while some young people think that the speed of the vehicle is not fast enough and modify the motor. This kind of modification is actually very dangerous.
Mr. Huang said that there are lithium batteries and lead-acid batteries commonly used in electric vehicles on the market, and the corresponding circuit design, protection system and motor are different. In order to make profits, some businesses refurbish and sell electric vehicle batteries, and even install the batteries on electric vehicles, which has great safety risks. In addition, after the modification of the electric bicycle battery, the terminal is often damaged, which will cause the cable wiring to be corroded and disconnected, at this time, the wire will be buckled at will, and the hydrogen gas that gathers inside the battery when it is charged will be ignited after ignition, resulting in an explosion. Although the mileage of the battery is long, the speed of the motor is also high, and the bearings and other components are overloaded, which seriously affects the life and safety of the electric bicycle.
On the other hand, the first thing that changes the circuit is the modification of an electric bike. The original thin wire needs to pass through a large current, the circuit will be unstable, and the car is prone to short circuit during charging or driving, resulting in spontaneous combustion.
Fire protection unauthorized modification of electric vehicles hides fire and traffic hazards
The fire department reminds the majority of electric bicycle sellers and manufacturers not to illegally modify electric vehicles for immediate interests, which is an illegal act. At the same time, consumers are reminded that they must buy regular and qualified electric vehicles and accessories, and unqualified electric vehicles, batteries, wires, and chargers will increase the risk of fire. For the safety of your own life and the life of others, do not modify the electric vehicle battery, install audio, lighting, etc., without authorization, which is easy to cause overload of the line and cause fire.
In addition to fire hazards, modified electric vehicles also have a lot of traffic safety hazards. After the battery is modified, the weight of the whole vehicle changes, and the speed increases, it is easy to lose control during driving, which will cause the danger of sliding and rolling forward. Therefore, modified electric bicycles are also easy to cause traffic accidents and affect road safety.
