Electric vehicles have become popular as a means of transportation. People find that the battery capacity of electric vehicles shrinks a lot in winter compared with summer, or it becomes difficult to charge or even start. In fact, many of this is due to consumers ignoring the maintenance of batteries in winter. The reporter visited several electric vehicle repair shops in the capital to understand the maintenance of electric vehicle batteries.
The maintenance personnel of an electric vehicle repair shop in Saihan District told reporters that the best working environment temperature of 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 life of the battery will be shortened. A normal lead-acid battery can guarantee the maximum driving distance of the vehicle is 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 released 100%. The mileage of a full charge will be greatly reduced. Therefore, the maintenance of the battery is very important.
First of all, in terms of charging, every time you go home, no matter how long you use it, you must charge it to keep the battery fully charged. It produces a kind of "memory", which affects its continuation mileage and also consumes battery life. When charging, insert the battery plug first, and then insert the power plug. When the charging is finished, pull out the power plug first, and then pull out the battery plug.
Secondly, start the electric car to avoid high-current discharge and reduce the number of people traveling. It is best to push it manually or assist in riding when climbing a slope, otherwise it will cause great damage to the battery. If the vehicle is not used for several weeks in the open air or in a cold storage, the battery should be removed and stored in a warmer room to prevent the battery from being damaged by freezing. And when the temperature is too low, the use time of the electric vehicle should be shortened as much as possible, and the electric vehicle should be charged in time. If you don’t plan to use the battery car in winter, don’t wait until the next year to recharge the battery. Instead, you should charge the battery once every month to ensure the storage capacity of the lead-acid battery and avoid acid spillage. Battery. The maintenance personnel said that to maintain the battery, remember to charge frequently and provide more assistance.
After half a year of use, it is best to go to the maintenance point to do a battery maintenance, properly replenish the electrolyte of the battery, adjust the specific gravity of the electrolyte, and check its power storage, maintain the specific gravity of the battery electrolyte, and increase the charging times if necessary. At the same time, it is also very important to clean the terminal posts of the battery and apply special grease for protection, which can ensure that the electric vehicle is reliable when starting and prolongs the life of the battery.
