Electric vehicles have become popular as a means of transportation. People find that the battery capacity of electric vehicles shrinks greatly in winter than in summer, or it becomes difficult to charge, or even start. In fact, most of this is due to consumers' neglect of battery maintenance in winter. The reporter visited several electric vehicle repair shops in the capital to learn about the maintenance of electric vehicle batteries.
The maintenance personnel of an electric vehicle maintenance shop in Saihan District told the reporter that the best working environment temperature of the battery is 15 ℃~40 ℃. Outside this temperature range, the normal operation of the battery will be affected and the battery life will be shortened. A normal lead-acid battery can ensure that the maximum driving distance of the vehicle is 50 km. Due to the principle of thermal expansion and cold contraction, when the ambient temperature is - 10 ℃, the battery power cannot be discharged 100%. The driving distance of a fully charged car in winter is much less than that in summer. Therefore, battery maintenance is very important.
First, in terms of charging, after going home every time, no matter how long you use it, you should charge it to keep the battery in a fully charged state. If you do not fully charge the battery occasionally, it has little impact on the battery, but you often do not fully charge the battery, the battery will have a "memory", affect its mileage, and also consume its service life. When charging, first plug in the battery plug, then plug in the power plug. After charging, first unplug the power plug, and then unplug the battery plug.
Secondly, start the electric vehicle to avoid heavy current discharge and reduce manned driving. It is better to promote or assist riding manually when climbing, otherwise it will cause great damage to the battery. If the vehicle is parked in the open air or cold storage for several weeks without use, the battery should be removed and stored in a warm room to prevent the battery from freezing and damage. In addition, if the temperature is too low, the service time of the electric vehicle shall be shortened as far as possible, and the electric vehicle shall be charged in time. If the battery car is not to be used in winter, the battery should not be recharged until it is used in the next year. Instead, the battery should be charged once every 1 month to ensure the storage capacity of the lead-acid battery and avoid damage to the battery due to acid spillage. The maintenance personnel said that when maintaining the battery, they should remember to charge frequently and help more.
After half a year of use, it is better to go to the maintenance site for battery maintenance, properly replenish the battery electrolyte, adjust the specific gravity of the electrolyte, check its electricity storage, maintain the specific gravity of the battery electrolyte, and increase the number of charges if necessary. At the same time, it is also important to clean the battery terminals and coat them with special grease for protection, which can ensure that the electric vehicle starts reliably and extends the battery life.
