How to maintain the battery

1. It is not suitable to use fast charging for a long time. Fast charging is for emergency use. I believe that most people will encounter that the car will run out of electricity on the way, and it will take a long time to charge for two yuan in 10 minutes. Fast charging has a great impact on the battery and accelerates the aging of the battery, but it is okay to charge it occasionally, so don’t worry too much. Because there are some car owners who don't dare to charge quickly if they know that the fast charge is not good, it shows that they still pay more attention to it. Therefore, fast charging is possible, but it is not advisable to do so for a long time. Because car owners do not pay attention to maintenance, they often encounter some deformed and difficult-to-disassemble electric vehicles when changing batteries. Second, there should be no excessive discharge and excessive discharge, which affects the service life of the battery. You may not know what it is. The vast majority of electric vehicles are 60V20A, which are connected in series by 5 batteries, and a single battery is 12V20A. Measured with a multimeter, the voltage is about 13V, so the voltage of the whole vehicle is 5*13Vu003d65V, and the electric vehicle can be seen by the liquid crystal display. In order to protect the lead-acid battery, an under-voltage protection value of 5*10.5Vu003d52.5V is set (not to go into details), and the battery discharge voltage cannot be lower than this value. This is tested by the controller. This is why when the electric car is running out of power, it will have a meal when it is accelerating. The accelerating voltage drops rapidly, undervoltage, the controller stops output, and the voltage rises, and then you can go again, and so on. Some controllers will be unable to accelerate when the battery is insufficient. Everyone should recharge in time and stop riding. 3. When to charge, how long does it take to charge, whether the new battery is used up, there is no special requirement about when to charge, it is suggested that the remaining 30% to 40% can be charged, so that you can charge enough power for the next time you go out. Riding halfway without electricity, resulting in over-discharge. If the battery is often used up, it will hurt the battery, and the service life will be severely shortened. There will be some analysis on the battery warranty statement. The charging time is 6-8 hours, preferably no more than 10 minutes. However, in many cases, the battery still has remaining power, and the charger will automatically change the light when it is overflowing. When the light is not changed, pay attention to it. Pay attention to whether the battery is very hot. Don't charge it for too long. A customer just charged it for two days. Because the light was not changed, she thought it was not overflowing and kept charging the battery. The rise is very strong. You can try a new charger, which is usually easy to do after the battery has been used for a long time. New batteries will store more than 90% of the electricity, so you don’t need to recharge them after you use them up. Many customers will ask if the battery is recharged the first few times. If you don’t know where it’s heard, just charge it when the battery is not enough. Fourth, to choose the same type of charger, the charger should be consistent with the battery parameters, and the 60V20A battery should use the 60V20A charger. The chargers are basically universal, so you don’t have to worry about whether a certain brand is dedicated or not; don’t just lend it to others, because some brand cars have different positions of the positive and negative poles of the charging socket, such as Luyuan, Xiaoniao, Supaqi, For example, the positive and negative poles of Luyuan are just put in. If your colleague uses the charger to charge it, it will be broken immediately without reverse connection protection. It is common to borrow someone else's charger to use it, which is to remind everyone. Also, some customers choose the wrong charger, the 48V20A battery buys the wrong 60V20 charger, and the battery is scrapped the next day, hot and swollen. Therefore, buy after optimistic about the parameters. The battery is afraid of high current. It can be charged with 48V12A, but it is very slow. Swelling battery 5. If it is not used for a long time, it should be overcharged before placing the battery. During long-term storage, the battery will self-discharge. Over time, the battery will lose power, which will affect the battery, and if you want to use it again, you may not be able to charge it. Everyone should pay attention to this situation. Many car owners have encountered such problems. It will be added every few months, you can see for yourself. 6. The temperature is too high in summer, so let it cool down before charging.
