Life span of new energy vehicles and fuel vehicles

How long the service life of a car depends on subjective factors. The car has "steel bars and iron bones", the surface is maintained, the varnish layer is waxed and protected, and the rust prevention treatment is carried out after scraping. As long as the surface does not damage the inner panel, there is no chance of rust. With the continuous improvement of living standards, the change cycle is getting shorter and shorter, and most car owners update it every 5 to 10 years. Not many people drive 300,000 kilometers.

Judging from the current situation, the durability of most fuel vehicles is very good, and the mileage of many car owners' family cars can exceed 300 thousand kilometers. There is no need to replace the three big cars, just simple maintenance. Different vehicles and brands will have different service lives. The tanker can be maintained between 10- 12. In the relatively immature environment of automobile culture, there is no classic automobile culture. In the process of transforming conventional energy into modern electric energy, the elimination speed of tanker may be accelerated appropriately, and these factors will make the actual service life unpredictable.

The life of new energy vehicles is directly related to their batteries. As we all know, battery is the main energy source of new energy vehicles. Once there is a problem with the battery, whether to replace it will easily affect the service life of the vehicle. The batteries of new energy vehicles are generally ternary lithium batteries. The advantage of this kind of battery lies in its larger capacity, which can hold more electricity under the same volume, and the technology of this kind of battery is also relatively perfect, so the consistency of the battery is better. Theoretically, the service life of this battery can reach 1500 cycles, more than 800 cycles when fully charged, and more than 1200 cycles when the battery is controlled between 25% and 75% in daily use.

In addition, the batteries of new energy vehicles may be lithium iron phosphate batteries. The advantages of this battery are that it can be recycled for more than 2000 times, with high charge-discharge rate and larger charge-discharge current. The shortcomings are also obvious. Compared with ternary lithium battery, it has poor consistency and low endurance. Under the same power, it will increase the weight and cost of the vehicle. Therefore, considering comprehensively, if the service life of new energy vehicles is maintained well, if the influence of vehicle endurance is not considered, the vehicle itself will be basically fine for 20 years.
