How do I charge a newly purchased electric vehicle battery?

The popularity of electric vehicles has made electric vehicles a standard means of transportation for many citizens. But there are frequent problems with electric vehicle batteries. What is going on? In fact, most of the batteries on the market are of qualified quality. Therefore, the problem largely lies in the use and maintenance, especially when you don’t pay attention to charging. It will cause problems such as shortened battery life. When many friends first bought the electric vehicle battery, they thought that they must be maintained. Then how do you charge the newly purchased electric vehicle battery for the first time? Must be charged immediately? It must be consumed. Can it be recharged by light? The first charge must be fully charged for 24 hours? The author tells you! 　　 1. The battery must be used up but not exhausted. When the battery of an electric car is newly purchased, the battery will not be too full, but it will not be too low, unless It is an old battery or inferior battery. When you use it, you should estimate the approximate distance you can travel based on the estimation of the merchant, so as not to run out of electricity or run out of electricity. When the electric vehicle power display has reached the last grid, it is necessary to consider not to ride, and to prepare for charging.　　2. Try to avoid charging indoors, and try to do it outdoors. The battery of an electric bicycle will run out of flammable gas when charging, so you must not charge it in a narrow, sealed environment. Choose ventilation, waterproof, and the ambient temperature should not be too high. Community charging piles are the most suitable 3. When conditions permit, try to choose daytime Charging is easy to control the charging time. Everyone knows that the battery should be fully charged when charging for the first time, but full charge does not mean overcharging. Charging during the day is easy to control the charging time, so that the battery will not be overcharged and discharged for the first time, which is easier Let the first chemical reaction in the battery normal.　　 4, 5-6 hours are fine, avoid overcharging. 　　 Regarding the charging time for the first charge, because the battery car battery has not been charged or discharged when it is not in use at the factory, and the normal operation of the battery must be ensured. Under normal circumstances, the charging time is about 5-6 hours, and the battery can be fully charged, and the subsequent use can be charged a little longer. Charging during the day can better control the time. After the battery has been used for half a year, it is recommended to deeply discharge the battery once a month, and then charge the battery of the electric vehicle after the deep discharge. The time is controlled at 12 hours. This will have great benefits for the power recovery of the electric vehicle battery.5. How much power is left when recharging is more appropriate?-It depends on the situation. Under normal circumstances, electric vehicles (not often carrying people, not climbing all day) Slope), when the remaining battery power is between 30% and 50%, it is best to charge, which can avoid the early capacity loss of the battery, and also avoid over-discharge; if you often take people and climb slopes, it is recommended that the remaining power be at 50%. Recharging; if the battery is not used at ordinary times and 60%-70% of the battery power is not used in a week, it is recommended to charge it once; if you go out or leave it for a long time, the battery will self-discharge and cause 'running' and the battery will lose power seriously. Affect the battery life, it is recommended to charge once a month. 6. Is it better to charge as often as possible?-It is correct to charge the battery frequently, and charge it after riding every day, but the situation is like this, if your battery can run 30 kilometers, then you ran. Charge it for 5 kilometers or 10 kilometers, which is not good for the battery, because when the battery is fully charged, there will definitely be gas overflow, and this gas is produced by the decomposition of water in the electrolyte, so water loss This happens. Frequent charging like this will increase the number of times the battery loses water and the battery will soon enter the expiration period. So a good way is if you don’t ride an electric bike the next day, you’d better charge it fully, but after you’ve ridden 5 kilometers or 10 kilometers, there is still enough distance to run the next day, so it’s best to wait. Recharge the battery after riding the next day, so that the water loss of the battery will be reduced, and the battery life will be prolonged. 7. After the first time, continue to pay attention to the first charge. Although it is not the first charge, but the second time is also regarded as a new car charge. At this time, you can let the battery car's battery run out, and then perform a long-term charge This charge can last for 8-9 or even 10 hours, in order to allow the battery car chemical reaction to go through a complete cycle, this is what electric car dealers told me. 8. For safety issues, keep in mind that when the battery car is charged for the first time, the charger may heat up very quickly and very high. Therefore, especially when charging in summer, the charger should not be placed on objects that are easy to heat and burn. Don't put it on the seat of the battery car to prevent fire, because many people have spontaneous combustion of the battery car when charging, please be careful.　　 In short, the maintenance and maintenance of electric vehicle batteries is very important. The correctness of the charging method directly affects the service life of the battery, and even improper charging methods may cause safety hazards such as fire. I hope that the majority of car owners will pay more attention. Previous: How often does the battery of an electric car need to be replaced?
