(Summary description)Electric bicycles are an important travel tool for citizens. While bringing convenience to everyone, they also bring safety hazards that cannot be ignored. On the evening of May 10, an electric car caught fire in an elevator in a residential area in Chengdu, Sichuan Province, resulting in five injuries, including a baby. The video quickly became a hot search on the entire network once it was released. Recently, many electric bicycle fire accidents have occurred in our city. On May 5, a fire broke out in the electric car shed in the revitalization project community of Sudi South Road, and 18 electric vehicles were burned. On May 19, a fire broke out in the home of a resident in Meiliqiao Village, Tongshan New District. The preliminary investigation revealed that the battery of an electric vehicle suddenly spontaneously ignited during the charging process and caused the fire. According to statistics, 80% of electric bicycle fires occur while charging, and it takes only ten seconds to charge the battery of electric bicycles from a fire to an explosion, which produces a large amount of toxic fumes and endangers the lives of the people. The fire department reminded the general public that behaviors such as "people and cars in the same house" and "flying wire charging" are very dangerous, and the disassembly of the battery and charging in the house are equally dangerous. Fire reminder 1. When buying an electric bicycle, pay attention to choosing a vehicle with a production license, a well-known market, and a well-known brand, and check whether the vehicle has undervoltage, overcurrent protection and short-circuit protection functions. 2. Electric vehicle maintenance should choose professional maintenance organizations or personnel, and shall not disassemble the electrical protection device without authorization to ensure that the electrical circuit and the protection device are intact and effective. 3. The vehicle should be charged outdoors as far as possible. Do not store electric vehicles in the lobby, walkway and stairwell on the first floor of the building. The charging line should choose the appropriate wire diameter, the line should be fixedly installed, and short-circuit and leakage protection devices should be installed. 4. The charging time of the vehicle should not be too long, and the charging should be carried out in accordance with the instructions. In principle, the charging time should not exceed 10 hours. 5. Where centralized storage is implemented, electric vehicles and bicycles should be stored separately, and fire-fighting facilities and equipment should be equipped in accordance with regulations.
