On August 13, according to foreign media reports, electric vehicle manufacturer Tesla claimed in its latest report that its two electric vehicles, model s and model x, lost only about 10% of the power battery when driving 200000 miles < p > the electric energy capacity of the power battery will decline with the increase of the driving mileage of the electric vehicle. The attenuation speed of the battery electric energy is one of the most worried problems for consumers when buying electric vehicles, and it is also one of the important indicators they consider when choosing electric vehicle brands < p > the longer the power battery runs, the longer the scrap recovery cycle and the longer the whole vehicle runs, which will undoubtedly promote the healthy and sustainable development of the electric vehicle industry < p > in the past few years, Tesla has also released data reports on the performance of electric energy attenuation when power batteries are used < p > this year, the company updated the battery operation performance data of model s and model x, claiming that after driving 200000 miles, the power battery capacity of these two electric vehicles remains about 90%, that is, only 10% is consumed < p > this data also confirms some actual use reports, that is, the battery power attenuation rate is faster in the first 100000 miles, but the power attenuation rate slows down and stabilizes in the next 100000 miles < p > Tesla believes that on average, the vehicle will be scrapped when it travels 200000 miles. The company said, "the design life of Tesla power battery is longer than that of the vehicle. We estimate that a car will be scrapped after driving about 200000 miles in the United States and 150000 miles in Europe. " < p > the above data only apply to model s and model x models, but Tesla claims that the power battery range of model 3 will reach 500000 miles. Moreover, the electric vehicle manufacturer aims to achieve a range of 1 million miles for its next-generation power battery < p > in the past few years, Tesla's two electric vehicles model s and model X have used different power batteries, and the attenuation performance of the electric energy capacity of these batteries is not very satisfactory < p > some media reported last year that Tesla's 90 kwh battery decays much faster than 85 kwh battery < p > < p > each point on the chart represents a model s or model x used by Tesla users at the end of 2017. The graph is based on real research data, so it can truly reflect the power attenuation performance of Tesla battery < p > in the figure, Y axis represents the current available battery capacity (KWH) of the vehicle, and X axis represents the total battery consumption (KWH) of the vehicle since it was on the road < p > it can be seen from the chart that in the first few years, the power attenuation rate of 90 kwh battery is almost twice that of the old 85 kwh battery < p > however, & nbsp; The attenuation rate of 90kwh battery power will gradually decrease with the passage of time and the increase of mileage（ Tianmen Mountain)
