How often is the best time to change the battery of an electric car?

At present, under normal use, the lead-acid battery replacement cycle is generally 2 to 3 years, and replaced after 500-600 cycles of use. Lead-acid storage batteries can be divided into maintenance-free gel batteries and maintenance batteries. Maintenance-free means batteries that do not need to add battery water. Maintenance batteries are batteries that add battery water. Maintenance-free gel batteries are at (temperature 5-40). ℃, humidity 20%-90%, mileage is not shortened), it can be recycled 500 times, the normal use life is 2 years, and it takes more than 3 years to be completely scrapped. Under normal use, the service life of the maintenance battery is generally about 1 year. It is completely scrapped for about 1.5 years. In addition, the length of battery use should also take into account the temperature of the environment and the charging and discharging conditions. If it is parked for a month without charging, the battery will always be in a loss of power, and it is easy to be scrapped. In this case, it is abnormal. Case. Under normal use, the service life of the lithium iron phosphate battery is 3-5 years, the cycle time is 1000 times, the ternary lithium ion battery is about 3 years, and the cycle time is about 3 years. Mainstream lithium-ion batteries are divided into two categories: one is lithium iron phosphate. This battery has energy density and stable performance, but it is greatly affected by low temperature and has a long cycle life. It can be used for about 1,000 times and can be used for 3-5 years. Electric bicycles use 18650 lithium ion iron phosphate batteries. The other is the ternary lithium-ion battery, which has high energy density, but is relatively active in nature, has a short cycle life, about 600-800 times, and a service life of about 3 years. This type of battery is the mainstream research for electric vehicles in the future. direction. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
