As we approach the year 2024, the performance and longevity of electric vehicle batteries have become critical topics of discussion. With the rapid growth of the new energy vehicle market, two major concerns regarding battery performance have emerged: degradation and safety.
Since 2016, China has implemented strict regulations concerning the lifespan of electric vehicle batteries, setting the requirement at a minimum of 8 years or 120,000 kilometers. As of now, the first generation of batteries that meets these standards is nearing the end of its lifecycle. This raises questions about the longevity and viability of the batteries used in new energy vehicles.
How long can we expect the power batteries of these vehicles to last? In 2016, the first batch of new energy vehicles was launched, and many consumers are now facing significant battery degradation. Furthermore, battery lifespan can vary greatly across different manufacturers and types, making it difficult to set a standard expectation. Generally, the lifespan of power batteries can extend to about 8 to 10 years under normal usage conditions, but actual usage may differ significantly due to variations in battery chemistry and production.
Experts suggest that the lifespan of batteries largely depends on the number of charge cycles they undergo. Different battery types exhibit different degradation patterns. For example, lithium iron phosphate batteries can reach about 3000 cycles, while ternary lithium batteries may last for approximately 2000 cycles. This indicates that even after reaching these cycle counts, batteries can still operate and maintain around 80% of their original capacity, allowing for continued use.
In practice, if a battery has completed 1 to 2 charge cycles per week, it can maintain performance for 8 to 10 years without significant issues. However, the critical point arises when considering battery replacement. After 8 years, can the battery still be used effectively? Industry insiders believe that the lifespan of a battery is not solely determined by its inherent quality but also by user habits and maintenance practices.
How should one manage battery replacement? Experts recommend regular checks on battery health, especially as the warranty period approaches. If a battery is nearing the end of its lifecycle, a professional assessment is advisable to determine whether it can still be safely used or if it needs replacement.
In the second-hand vehicle market, the condition of electric vehicle batteries can greatly influence resale prices. Currently, there is a noticeable trend of consumers being cautious about purchases of used electric vehicles, primarily due to concerns about battery health and performance. As the market matures, potential buyers are increasingly educated about battery longevity and performance expectations.
In conclusion, the future of new energy vehicles and their battery technology will likely hinge on improving battery lifespan, performance, and safety standards. With advancements in battery technology, it is expected that the next generation of electric vehicles will offer improved durability and efficiency, addressing current consumer concerns.
