Electric vehicles have become popular as a means of transportation. People find that the battery capacity of electric vehicles in winter is much smaller than in summer, or it becomes difficult to charge or even start. In fact, many of this is due to consumers neglecting the maintenance of batteries in winter. The reporter visited several electric car repair shops in the capital to learn about the maintenance of electric car batteries.
A maintenance staff at an electric vehicle repair shop in Saihan District told reporters that the best working environment temperature for the battery is 15 degrees Celsius to 40 degrees Celsius. 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 guarantee a vehicle's maximum driving distance of 50 kilometers. Due to the principle of thermal expansion and contraction, when the ambient temperature is -10 degrees Celsius, the battery's power cannot be discharged 100%. The mileage of a full charge in winter is longer than that in summer. The mileage of a full charge will decrease a lot. Therefore, the maintenance of the battery is very important.
First of all, in terms of charging, every time after going home, regardless of the length of use, the battery must be charged to keep the battery in a fully charged state. If the battery is not fully charged occasionally, the battery will be It produces a kind of "memory", which affects its continuous mileage and also consumes battery life. When charging, insert the battery plug first, and then the power plug. When charging is over, first pull out the power plug, then pull out the battery plug.
Secondly, start the electric vehicle to avoid high-current discharge and reduce the number of people to use. It is best to push it manually or assist riding when climbing, otherwise the battery will be greatly damaged. If the vehicle is parked in the open air or cold storage for several weeks, the battery should be removed and stored in a warmer room to prevent damage to the battery from freezing. Moreover, when the temperature is too low, the use time of electric vehicles should be shortened as much as possible, and charging should be carried out in time. If you do not plan to use the battery car in winter, do not keep the battery recharged in the next year. Instead, charge the battery once every 1 month to ensure the storage capacity of the lead-acid battery and avoid acid spillage damage. battery. The maintenance staff said that when maintaining the battery, remember to charge frequently and assist more.
After half a year of use, it is best to do a battery maintenance at the repair point, properly replenish the battery's electrolyte, adjust the specific gravity of the electrolyte, and check its power storage, maintain the specific gravity of the battery electrolyte, and increase the number of recharges if necessary. At the same time, it is also important to clean the terminals of the battery and apply special grease to protect it. This can ensure the reliability of the electric vehicle when it starts, and extend the life of the battery.
