With the global emphasis on environmental protection and sustainable development, new energy vehicles have gradually become the new favorite of the automobile market. More and more consumers have begun to pay attention to the performance and service life of new energy vehicles, especially the durability and attenuation of batteries. After all, cars are long-term means of transportation, and their reliability and economy are crucial. So, can new energy vehicles be driven for more than 10 years? To what extent will the battery decay after 10 years? Today, we will explore these issues in depth and reveal the truth about new energy vehicle batteries for you.
1. Service life of new energy vehicle batteries
(I) Mileage
General situation: At present, new energy vehicle batteries can generally travel 150,000 to 200,000 kilometers after 10 years of normal use. Taking ordinary pure electric vehicles as an example, their cruising range is between 400 and 600 kilometers. The average family travels about 15,000 kilometers per year, and the cumulative mileage in 10 years can reach 150,000 kilometers, which can meet daily travel needs.
Some models perform better: such as Tesla Model S and NIO ES8, the range can reach 600-700 kilometers, and the mileage can reach more than 200,000 kilometers in 10 years. In theory, there is basically no problem in driving new energy vehicles for 10 years.
Actual case: The actual usage data of many car owners also supports this view. For example, some early car owners who bought BYD Qin have driven their vehicles for more than 100,000 kilometers, and the battery performance is still stable, and the vehicle can drive normally.
(II) Battery technology progress
Battery material improvement: In recent years, the battery technology of new energy vehicles has been continuously improved. For example, lithium iron phosphate batteries (LFP) and ternary lithium batteries (NCA/NCM) are the two mainstream battery types. Lithium iron phosphate batteries have higher safety and longer cycle life, while ternary lithium batteries have more advantages in energy density. With the development of technology, the cycle life and performance of batteries have been significantly improved.
Battery Management System (BMS): Modern new energy vehicles are equipped with advanced battery management systems (BMS), which can monitor the temperature, voltage and current of the battery in real time, ensure that the battery operates within a safe range, and extend the battery life.
2. Battery degradation within 10 years
(I) Degradation range
Expert calculation: According to expert calculation, the capacity of new energy vehicle batteries will decay by about 15% – 20% after 10 years of use. For example, if the initial range of the vehicle is 500 kilometers, the actual range may be reduced to about 400 – 450 kilometers after 10 years. This degradation range is not particularly large.
Actual case: A car owner has used a Tesla Model S for 8 years, and its range performance is basically consistent with the predicted data of the battery manufacturer, meeting the official 15% degradation standard. This shows that as long as the vehicle is used and maintained properly, the battery degradation can be controlled within a reasonable range.
(II) Influencing factors
Use environment: The service life and decay rate of the battery are closely related to the use environment. Both high and low temperature environments will affect battery performance. For example, in a high temperature environment, the chemical reaction of the battery will accelerate, causing the battery to age faster; while in a low temperature environment, the discharge performance of the battery will decrease, affecting the vehicle’s range.
Charging habits: Frequent fast charging and overcharging will also accelerate the attenuation of the battery. It is recommended that car owners use slow charging as much as possible and avoid overcharging for a long time. For example, some car owners will try to avoid charging the battery to 100% during use, but keep it in the range of 80% – 90%, which can effectively extend the battery life.
III. The importance of choosing a reliable brand
(I) Brand advantages
Big brand batteries: If you are more concerned about battery attenuation, it is recommended to buy new energy models from big brands such as BYD, Tesla, Weilai, and Nissan. These brands use big brand batteries, and the quality and life are more guaranteed, and they are relatively more reliable. For example, BYD’s blade battery uses lithium iron phosphate material, which has higher safety and longer cycle life.
After-sales service: Big brands usually provide more complete after-sales service. For example, Tesla provides car owners with up to 8 years of battery warranty service, which greatly reduces the owner’s use cost and worries.
(II) Market feedback
User evaluation: After using new energy vehicles from big brands, many users have given high praise to their battery performance and overall vehicle quality. For example, users of NIO Automobile have reported that the battery management system of the vehicle is very intelligent and can effectively extend the battery life. At the same time, the after-sales service of the vehicle is also very timely and thoughtful.
Industry data: According to data from industry research institutions, the battery decay rate of new energy vehicles from big brands is significantly lower than that of some niche brands. This shows that choosing a big brand can not only get more reliable products, but also save more costs in long-term use.
IV. How to extend battery life
(I) Reasonable use
Avoid extreme temperatures: Try to avoid parking the vehicle for a long time in high or low temperature environments. For example, in summer when the temperature is high, the vehicle can be parked in a cool place; in winter when the temperature is low, the vehicle’s preheating function can be used to adjust the battery temperature to a suitable range in advance.
Control charging frequency: It is recommended that car owners arrange the charging frequency reasonably according to actual needs and avoid frequent charging. For example, if the vehicle’s range is sufficient to meet daily commuting needs, it can be charged every few days instead of every day.
(II) Regular maintenance
Battery inspection: Regularly check the battery status, including battery voltage, temperature and appearance. If the battery is found to be abnormal, such as bulging or leakage, contact after-sales service in time for processing.
Vehicle maintenance: In addition to battery maintenance, other parts of the vehicle also need regular maintenance. For example, regularly changing brake fluid, checking tire pressure, etc., all of which help improve the overall performance and safety of the vehicle.
