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 left for a month without charging, the battery will always be in a loss of power and will easily be scrapped. In this case, it is abnormal. Case. 2.jpg 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 battery is about 3 years, and the cycle time is about 3 years. Mainstream lithium batteries are divided into two categories: one is lithium iron phosphate, which has stable energy density and stable performance, but is greatly affected by low temperature, has a long cycle life, about 1,000 times, and can be used for 3-5 years. Both use 18650 lithium iron phosphate batteries. The other is the ternary lithium 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 direction for electric vehicles in the future. . Disclaimer: Some pictures and content of articles published on this site are from the Internet.
