In recent years, electric bicycles have become a means of transportation for urban and rural residents to travel in close quarters, with the characteristics of economy, convenience, and environmental protection. Currently, the number of electric vehicles is 150 million.
Due to the large base of electric vehicle ownership and its rapid growth, counterfeit and fake and unlicensed products flood the market, burying a large number of congenital hidden dangers that cause fire. While we enjoy the convenience of electric vehicles, let us pay attention to the safety of electric vehicles. Recently, the reporter learned from the Public Security Fire Brigade in Shihezi City that from 2010 to 2012, there were 4 fire accidents caused by electric vehicles in the country, causing 28 deaths and 26 injuries. Six fires also occurred in Shihezi City. Fortunately, no casualties or major property losses occurred.

Expert analysis, improper charge caused fire
“My family lived on the first floor. In October 2011, there was one o'clock in the morning and one in the morning. When I got up in the bathroom, I suddenly smelled an unpleasant smell. I thought it was a fire in my house. I crossed the window and found out. When I got up, I immediately called the police and the fire brigade extinguished it. Later I learned that it was an electric car that was being charged.†Mr. Zhang, who lives in the No. 8 neighborhood in Shihezi City, was still frightened when he talked about this matter. "If the fire is big on that day, people living in the building can be in danger. To facilitate charging, people in the upstairs have pulled out more than ten meters of wires to charge outside the windows of my house. Now the property department of the community is soon implemented. This problem, set up an independent electric vehicle charging station in the bike shed, electric bicycle parking and charging management, to eliminate security risks in a timely manner, and now I can feel more at ease.†Mr. Zhang told reporters.
Why do electric cars prone to fire when charging? The reporter specifically interviewed Mr. Zhao of an electric vehicle distribution department in Shihezi City, Xinjiang.
Some of the electric vehicle fires occur while driving, but most occur during the charging process. The main cause of fire in electric vehicles is the overload and short circuit of the electrical circuit of the vehicle. Because no electrical safety device or electrical safety device is not qualified, the power cannot be cut off in time. The high current ignites the insulation or other flammable combustible materials. Caused. The main reason for the fire during the charging process is the short circuit of the electric circuit of the electric vehicle, the overload of the charger circuit, and the battery fault of the electric vehicle.
Keep away from fire and improve your ability to prevent yourself
How to control the occurrence of electric vehicle fire at the source? Mr. Zhao said that the main electrical components in electric vehicles include controllers, chargers, rechargeable batteries, and motors. The main causes of the electric vehicle's fire are short circuit of the electric circuit, excessive contact resistance, overload, explosion of the battery, and fire.
When consumers purchase electric bicycles, they should pay attention to selecting electric vehicles with production licenses, high market awareness, and well-known brands, and pay attention to checking whether the electric vehicles have undervoltage, overcurrent protection, and short circuit protection functions.
Mr. Zhao reminded the masses that the vehicle should be carried out outdoors when charging, or the battery should be removed and charged separately. Charging line should choose the appropriate wire diameter, line laying should be fixed installation, install short circuit and leakage protection device. Charging of vehicles should avoid charging for too long and should be charged in accordance with the specification. The charging time should not exceed 10 hours in principle.
Strengthen vehicle management when storing vehicles
Shi Xiaozi, chief of staff of the Fire Prevention and Supervision Division of the Public Security Fire Brigade in Shihezi City, said that effective prevention of electric vehicle fire accidents requires centralized storage, separate storage of electric vehicles and bicycles, and deployment of fire-fighting facilities and equipment as required. Do not store electric vehicles in the hall, walkways and stairwells on the first floor of the building. The self-built houses in Chengzhong Village are equipped with a simple automatic sprinkler system for rooms where electric cars are stored, fire doors are installed, and fire-fighting equipment is provided.
