What is special about charging electric bicycles?
What is special about parking and charging electric bicycles! Believe that we have all seen a lot of news about the explosion of electric bicycle charging, so what is the particularity of electric bicycle charging? Today, I will give you a specific introduction to the two-wheeled electric bicycle. For a long time, electric bicycles have gradually become a common means of transportation for the public due to their advantages of being very light and convenient. However, with the increase in the number of electric bicycles, fires and safety accidents caused by irregular use of electric bicycles frequently occur. At around 7:35 pm on May 10, an electric bicycle in Unit 1, Building 9, Congshujiayuan District, Chengdu City, suddenly caught fire in the elevator, causing 5 people to be injured in varying degrees. It was distressing. What will happen to the scene if the electric bicycle catches fire? Experiments show that an open flame appears 30 seconds after an electric bicycle is short-circuited, and the poisonous gas produced by the combustion is enough to suffocate people within 100 seconds. After 4 minutes, the highest instantaneous temperature reached 1200 degrees Celsius. At this time, the black smoke was filled and the visibility was basically zero. The speed and intensity of the fire of electric bicycles is beyond imagination. What causes the electric bicycle to catch fire? 1. The line is aging, and the electric bicycle has been used for a long time, and the internal connection line of the vehicle is prone to aging and short-circuiting. If the wires in the car are short-circuited, and the external temperature is too high, it is easy to burn. Tips: The whole vehicle line is prone to ageing after a long time. It is recommended that the user should go to the maintenance point for inspection regularly. In addition, after riding in hot weather, place the car in a cool place and wait for the temperature of the car and the battery to cool down before charging. 2. The battery accessories are not turned off. After the battery has been used for a long time, the internal circuit is easy to short circuit and cause spontaneous combustion. In addition, if the battery is not installed properly, it will cause short-circuit heating after long-term use of friction, which will cause the battery to burn. Tip: According to the relevant technical standards, the ordinary battery in the electric bicycle has a service life of 1.5-2.5 years. Therefore, it is recommended that the user replace the battery regularly, and must buy a matching battery at a regular store to avoid choosing inferior batteries. 3. Mixing of chargers does not match. Now many families have more than one electric bicycle, and electric bicycle chargers of different brands must not be mixed. This will not only cause damage to the electric bicycle battery, but also bury potential safety hazards. Tips: Different brands of chargers should not be mixed. If the charger is damaged, please buy the same brand and the same model from a regular store. 4. Overcharge procrastination. In the actual situation, many car owners do not charge according to the instructions of the user manual, and they are used to overnight charging in order to save trouble. The longer the charging time, the higher the charger temperature. When the battery is in an overcharged state, if the cooling fan stops working, the temperature of the charger will increase exponentially, bringing safety hazards. In addition, too long charging time can easily lead to overload of the charger, short circuit of the electrical circuit, and fire. Tips: Pay attention to the timing and duration of charging the electric bicycle. When the battery has used up 70%-80% of the power, it should be charged in time. Generally, it is 6-8 hours in summer and 8-10 hours in winter. The battery should not be over-discharged. Or recharge. 5. When multiple electric bicycles are charged at the same time, it may cause voltage instability and easily lead to safety accidents. In addition, for convenience, some car owners pull out the power strip from their homes to charge the car flying cables. The exposed wires are exposed to the wind and sun, which are particularly prone to leakage and fire. Tip: Never pull the wire privately, and be sure to charge it at a parking spot equipped with a charging device for electric bicycles. Charging in these places, one is to prevent the wire from aging due to the sun and rain, the other is the location of the carport is relatively independent, and the safety factor is relatively high. Fire extinguishers, some are also equipped with video surveillance and automatic sprinkler fire extinguishing systems, making charging safer. 6. Unsafe charging environment Some car owners store electric bicycles in stairwells, walkways or push electric bicycles indoors for charging. In the event of a fire on an electric bicycle, flames and dense smoke will block the safety exits and escape routes of the building, easily causing casualties. Tip: Do not charge in the stairwell, aisle or indoors, in case the electric bicycle catches fire, so as not to expand the fire and cause a fire. How to prevent electric bicycle fires? In recent years, laws and regulations prohibiting the parking and charging of electric bicycles in buildings have been introduced successively. On September 27, 2017, the Jiangsu Provincial Fire Safety Commission issued the 'Fire Safety Instructions for Electric Bicycle Parking and Charging Sites and Civil Building Gas Use SitesBuilding evacuation passages, safety exits, stairwells (door openings), floor corridors, indoor parking and charging in front of elevators; parking and charging in group rented houses are strictly prohibited; parking and charging in crowded places are strictly prohibited. Data shows that 80% of electric bicycle fire accidents occurred during charging, 66.7% of accidents occurred between 8 pm and 5 am the next day, and most of them occurred during the charging process, and 90% of accidents occurred in the hall and aisle. As well as stairwells and other places. Take precautions before 'burning' for safety, these electric bicycles are safe to use and remind you to quickly collect and forward! The above is the content for everyone to introduce, you can learn more about it in detail, I hope it can help you.
