How Many Years Can a Pure Electric Vehicle Last?
1 Answers
Electric vehicles can last for 8 years. According to relevant national laws and regulations, the battery packs of new energy vehicles sold in the market must meet a warranty period of at least 8 years or 120,000 kilometers. The batteries in electric vehicles undergo normal degradation. When the power battery reaches a certain lifespan, its performance will significantly decline, necessitating a battery replacement. Development of Electric Vehicle Batteries: The research and development of electric vehicle batteries have evolved from lead-acid batteries and nickel-metal hydride batteries to lithium-ion batteries, each with its own advantages and disadvantages. Lead-acid batteries, the earliest to appear, have the longest usage history and belong to the storage battery series. They offer the best safety performance, rarely experiencing explosions or fires, though their energy storage efficiency is not ideal. Lifespan: The mandatory requirement for battery cell lifespan in China is over 1,000 cycles. Generally, lithium iron phosphate batteries can achieve 2,000 cycles, while the average lifespan of ternary lithium batteries ranges from 500 to 1,000 cycles.
