Winter electric maintenance and computer precautions

In the cold winter weather, electric vehicles 'strike' frequently. Maintenance personnel said that most of the problems occurred in the battery. Some electric vehicle batteries were not fully charged, and some electric tricycle batteries were full but not enough. The cold weather has a certain impact on the battery of electric vehicles. Users should pay attention to the maintenance of electric vehicles. Master Wang, an electric vehicle after-sales service staff member, told reporters: 'Recently, many people have reported that their cars are not as easy to ride as before. They think that the battery is broken. In fact, due to the arrival of winter, the temperature drops, which has a certain impact on the use of battery energy. Master Wang said that due to the principle of thermal expansion and contraction, the energy storage capacity of a normal lead-acid battery in cold weather is reduced. Therefore, the mileage of the car will be lower than in other seasons. , Consumers do not have to worry about it. Master Wang also reminded the majority of electric vehicle owners that under low temperature conditions, batteries generally suffer from poor charging acceptance and insufficient charging. At this time, the charging voltage must be increased, the charging time must be prolonged, and heat preservation and anti-freezing measures must be taken to ensure sufficient charging. , Extend the service life of the battery. The battery should be charged frequently. Don't wait until the battery is used up. It is better to charge half the battery. In addition, in order to prevent the battery from freezing, the electric tricycle battery can be placed in a house with a higher temperature when not in use, and should not be placed directly on the ground. If the battery cannot be removed, the electric car can be parked in the house overnight. Try not to put the electric car charger on the car, because sometimes the road bumps can easily cause a short circuit inside the charger, and it is easy to cause spontaneous combustion when recharging; the charger should be placed in a place where it is easier to dissipate heat to prevent the charging time from passing Long, overheating of the charger can cause fire; the car should try to avoid driving on rainy and watery roads to prevent the motor from entering water and short-circuiting and catching fire during charging. The most important thing is that once an electric tricycle ignites spontaneously, the car owner must never take the battery, because the battery may explode during the combustion process. You should use clothes, raincoats, etc. to slap the fire place vigorously. In the early stage of the fire, it can be extinguished in time.
