The electric vehicle is turned hard, and the battery is over discharged! Does this hurt the battery?
The Electric vehicles has been idle for a month at home, why is there only half of the power left? Am I using it incorrectly? There is still a problem with the battery quality itself. With these questions, Xiao Bian has done his homework, and today I will start sharing knowledge!
Under normal circumstances, the electric vehicle battery will automatically discharge 1% -2% every day. If it is left for a long time, all the electricity will be discharged, so the battery that has been left for a month will only have half the power.
However, I would like to remind everyone that although self-discharge of electric vehicles is normal, if we use them improperly, we will cause electric vehicles to over-discharge. This is very harmful to the battery. Let's take a look at what causes the battery to over-discharge? Let's first look at the reasons for battery self-discharge.
First, the storage time is too long. After long-term storage, the battery will be discharged due to changes in the electrolyte.
Second, the electrolyte is not pure and contains impurities, so a certain potential difference is formed, which causes the battery to short-circuit and the power is consumed.
Third, when there is a bridge or short circuit outside the battery, when the positive and negative poles are connected, a severe discharge phenomenon will occur. In addition, when the battery case or the top cover has spilled electrolyte, it will also cause discharge.
Fourth, during the use of the battery, if the battery case leaks, or if daily care is not taken, causing water to enter the battery box, it will also cause the battery to self-discharge.
It can be seen that there are many reasons for the self-discharge of the battery. In daily use, we should also pay attention to these conditions to avoid excessive discharge of electric vehicle batteries, which will affect battery life. So how to prevent the battery from over-discharging?
First, strengthen maintenance and charge in time
During maintenance, pay attention to the cleanliness of the battery, and check for damage frequently. In addition, after the battery is used, if it is found that the battery level is less than 30%, it must be charged in time, and the battery must not be overused.
Second, handle gently
The electrolyte in Electric vehicles batteries is very important, so be sure to handle it gently during handling to avoid collision and damage to the case, which will cause the electrolyte to leak.
Third, check the vehicle frequently to ensure safe use
During the use of electric vehicles, various faults in the wiring and various components will occur with the extension of the time limit, which will seriously affect the mileage and shorten the service life. Therefore, it is necessary to regularly inspect various components inside the vehicle and find that there are rust or oxidation on the line, and they should be replaced in time.
Fourth, prevent moisture
In the course of riding an electric vehicle, if you do not pay attention to it, when it is raining or the road area is water, the battery box is prone to water, causing the battery to short circuit and cause self-discharge. Therefore, in this case, try to avoid wading or direct rain. At the same time, regularly check the inside of the battery box and find that there is direct cleaning of the accumulated water to keep the battery box dry.
Electric vehicles are our good partners for traveling, so we must pay attention to their maintenance to prevent the occurrence of over-discharge of the battery.
