The lifespan of ternary lithium-ion batteries in new energy vehicles is generally measured by the number of battery cycles. National laws and regulations stipulate that when the capacity of a power lithium-ion battery decays to below 80%, it must be forcibly recycled and reused in a tiered manner.
Meanwhile, regarding the cycle life of power lithium-ion battery cells, the national mandatory requirement is that they must be more than 1,000 cycles. As for the entire power lithium-ion battery pack, lithium iron phosphate can generally achieve 2,000 cycles, while ternary lithium-ion batteries have an average level of 500-1,000 cycles, and well-made ones can reach more than 1,000 cycles.
Regarding battery life, the lifespan of lithium-ion batteries in general electronic products is approximately 5 to 20 years, with an average of 8 years. However, with current technology, the lifespan of lithium-ion batteries in electric vehicles is only about 3-5 years. The reason for the shorter battery life in electric vehicles is mainly due to the influence of the operating environment and large-scale charging and discharging. If the capacity of the lithium-ion battery pack in an electric vehicle decays to below 80% of its initial capacity, the driving range of the electric vehicle will be significantly reduced. When the battery capacity decays to below 70%, the battery must be replaced.
