Electric vehicles have become popular as transportation means. It has been found that the battery capacity of electric vehicles in winter is much smaller than that in summer, or it becomes difficult to charge or even start. In fact, this is mostly because consumers ignore 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 the reporter that the best working environment temperature of the battery is 15 degrees Celsius ~ 40 degrees Celsius. Outside this temperature range, it will affect the normal operation of the battery, and the battery life will be shortened. A normal lead-acid battery can ensure that the maximum distance traveled by the vehicle is 50 kilometers. Due to the principle of thermal expansion and contraction, when the ambient temperature is -10 degrees Celsius, the battery capacity cannot be released 100%. In winter, the mileage is fully charged. Fully charged mileage will be reduced a lot. Therefore, it is very important for the maintenance of the battery.
First of all, in terms of charging, every time you go home, no matter how long you use it, you need to charge it to keep the battery in a state of full power. If it is not fully charged, it will not affect the battery, but it will not be fully charged. Produces a "memory" that affects its mileage and also depletes battery life. Plug in the battery plug first, then plug in the power plug. When charging is complete, first pull the power plug and then pull the battery plug.
Secondly, start the electric vehicle, avoid large current discharge, reduce the manned exercise, and it is best to carry out or assist the ride when climbing the slope, otherwise the damage to the battery is great. If the vehicle is not used for a few weeks in the open air or cold storage, the battery should be removed and stored in a warmer room to prevent the battery from freezing. When the temperature is too low, the use time of the electric vehicle should be shortened as much as possible, and it should be charged in time. If you are not going to use the battery car in the winter, the battery should not be recharged until the year of use. Instead, the battery should be charged once every 1 month to ensure the storage capacity of the lead-acid battery, while avoiding acid spillage. battery. Maintenance personnel said that to maintain the battery, remember to charge and help.
After using for half a year, it is best to do a battery maintenance at the maintenance point, properly replenish the electrolyte of the battery, adjust the specific gravity of the electrolyte, check the storage condition, maintain the specific gravity of the battery electrolyte, and increase the number of times of charging if necessary. At the same time, it is also important to clean the battery terminals and apply special grease to protect them. This ensures that the electric vehicle is reliable and extends the life of the battery.
