In winter, the temperature drops, and there are many weather conditions such as low temperatures, rain, snow, and freezing. The road environment is complex and changeable, so no matter how you go out, you must tighten the string of safety. Do not illegally modify electric bicycles to prevent charging accidents; Before driving, carefully check the condition of the car; When encountering extreme weather, reduce speed and control distance in a timely manner, strictly abide by traffic safety regulations... Master scientific prevention and emergency response knowledge to ensure safe arrival for every trip. ——How to eliminate hidden dangers in electric vehicle charging? Recently, Ms. Liu, a resident of Suzhou City, Anhui Province, accidentally touched the charging port while charging her electric bicycle outdoors after rain, injuring her hand and shattering her gold bracelet. This is a short circuit accident caused by a humid environment, "analyzed Wang Lin, an electricity inspector at the Fuli Branch of State Grid Suzhou Power Supply Company. The charging port of the electric bicycle is equipped with positive and negative electrodes, and the hand and gold bracelet are both conductive. When they come into contact with the electrodes, a current circuit is formed, causing a short circuit. In winter, there are many rainy and snowy weather conditions, and the charging port is prone to residual rainwater or moisture, which increases the risk. Regarding this type of safety hazard, Wang Lin suggests: firstly, perform a "dry check" before charging, wipe the charging port and battery interface with a dry cloth to confirm that there is no water accumulation or moisture before plugging in; Secondly, try to avoid outdoor charging during rainy and snowy days. You can choose outdoor centralized charging stations with rain shelters and other shielding devices. Do not directly connect to the power supply in rain and snow; The third is to keep your hands dry when plugging in and out the plug, do not operate with wet hands, and do not let metal objects such as keys near the charging port. The low temperature in winter leads to a decrease in battery life, and some users are accustomed to charging overnight. However, overcharging the battery can easily cause internal heating, bulging, short circuits, and fires. ”Liu Haifei, deputy head of the Suzhou Fire Rescue Brigade, stated that the total charging time for electric bicycles should not exceed 12 hours. "Once the battery bulges or leaks, it must be immediately stopped and replaced. If there is smoke, abnormal noise, or burning during charging or use, it often indicates that the electrical circuit is overheated or short circuited, and may develop into an open flame or even explosion within 1 minute." In such cases, power can be immediately cut off and dry powder fire extinguishers can be used to put out the fire. If the fire has started or smoke is rapidly spreading, it must be evacuated decisively and the 119 fire alarm number can be called. Unauthorized modification of batteries, installation of high-power motors, or wrapping of the vehicle body with a sealed anti cold cover can disrupt the balance of the vehicle's electrical system, leading to overloaded operation of the circuit and easily causing short circuits and fires, and such behavior violates laws and regulations. ”Bai Yan, Deputy Branch Leader of the Traffic Management Detachment of Suzhou Public Security Bureau, reminded. Car owners need to use manufacturer certified compliant accessories when replacing batteries, and absolutely do not use "three no" or refurbished batteries; When encountering rainy or snowy weather, slow down and avoid roads with accumulated water or ice; Riding early in the morning and overnight requires wearing bright colored clothes or sticking reflective strips. What details should be paid attention to before driving? It's getting cold, and the number of people traveling by car has significantly increased. But many drivers tend to overlook a comprehensive inspection of the vehicle's condition, increasing the risk of traffic accidents. ”Bu Leyang, the squadron leader of Datong Brigade, Huainan Traffic Police Detachment, Anhui Province, said. The decrease in winter temperature leads to a decrease in tire pressure, and prolonged driving with insufficient tire pressure may cause tire deformation or even blowouts. ”Bu Leyang said, "In addition, it is also crucial to inspect the vehicle's oil and water, braking, lighting and other systems. The normal operation of brake oil, antifreeze, wipers, brake pads, high and low beam lights, fog lights, etc. is a prerequisite for ensuring travel safety." Bu Leyang once handled an accident: the vehicle's wipers were aging, and the rainwater on the front windshield was not wiped off in a timely manner when driving in rainy weather, which affected the driver's vision. When turning right, it collided with an electric bicycle waiting on the roadside. In winter, there is a large temperature difference between the inside and outside of the car, and there are also requirements for car defogging. Bu Leyang believes that many drivers are accustomed to turning on the warm air for defogging only after the glass has fogged up and affected their vision. However, when the warm air is first turned on, the large temperature difference between the inside and outside of the car can cause the fog to intensify, resulting in a brief blind spot period. The correct approach is to first use cold air to quickly remove fog when fog affects the line of sight, and then switch to warm air when continuous anti fog is needed. In addition, the internal circulation cannot be used continuously, and the external circulation should be switched at intervals to keep the air in the car fresh and prevent the driver from getting sleepy due to lack of oxygen. The parking details cannot be ignored either. Bu Leyang reminds that vehicles should not be parked under trees in winter to prevent the accumulation of fallen leaves from blocking drainage holes; After snow, it is necessary to clean the front windshield and roof of the car in a timely manner to prevent snow from slipping and blocking the line of sight or causing accidents while driving. For users of new energy vehicles and fuel vehicles, Buleyang also provides targeted suggestions: "Before charging new energy vehicles, be sure to dry the interface to avoid outdoor charging in rainy and snowy days; for fuel vehicles, do not wait for the fuel level to be too low before refueling, as the fuel tank is vulnerable to fuel pump damage in low temperature environments. Every winter, there are many requests for help due to vehicle power or fuel shortages, which not only delays time but also affects road safety." How to drive in severe weather? The number of severe weather conditions increases in winter, and the road environment is complex and changeable. A slight negligence by drivers may lead to accidents. ”Li Shaoshao, the head of the Traffic Management Brigade of Huoshan County Public Security Bureau in Lu'an City, Anhui Province, said. In the past three years, 76.2% of drivers with more than 5 years of driving experience have been involved in traffic accidents in Huoshan County during severe weather conditions. This indicates that having extensive driving experience cannot completely avoid accidents. Adverse weather conditions combined with the driver's subjective negligence become the main cause of accidents, "said Li Shaoshao. Li Shaoshao recalled that one morning in January 2024, due to freezing rain, the middle section of Yingbin Avenue in Huoshan County experienced icing. A small truck suddenly rolled backwards while waiting at a red light due to the slippery road surface. But the driver was not focused at the time and failed to notice in time, only realizing it after colliding with the vehicle behind. Fortunately, the accident did not cause any casualties, which reminds drivers to remain vigilant in adverse weather conditions, "said Li Shaoshao. Deceleration, control distance, and vigilance - these are the safety iron laws that must be followed when driving in adverse weather conditions. ”Li Shaoshao said. Based on different weather conditions, Li Shaoshao provides specific suggestions: when driving in rainy or snowy weather, the speed should be reduced to about half of the normal road conditions, and the distance between vehicles should be maintained at least twice as much as usual; Avoid sudden braking and sudden turning, and slow down in advance before turning; When passing through flooded roads, observe the trajectory of the preceding vehicle, confirm that the water depth does not exceed half of the tire, and then pass at a low speed and uniform speed. Special attention should be paid to the use of lighting during heavy fog weather. ”Li Shaoshao added, "When the visibility is below 100 meters, it is necessary to turn on fog lights, low beams, clearance lights, and hazard warning flashers, but do not use high beams, as they will cause light reflection to intensify the fog effect. You should drive on the right side and maintain a safe distance." In response to emergency situations, Li Shaoshao also shared disposal tips: "When the vehicle slides on ice and snow roads, gently adjust the steering wheel according to the direction of the slide, and avoid hitting the direction forcefully. If the vehicle is trapped, do not forcefully step on the accelerator. You can lay sand and gravel to increase friction, and seek help in a timely manner if necessary
