How Many Years Can a Tesla Battery Last?

[AugustAnn]

Tesla's official data on battery lifespan is 450,000 to 600,000 kilometers, roughly equivalent to about 20 years of use. In reality, electric vehicle batteries are not nearly as fragile as some might think. According to domestic regulations, electric vehicles must provide a warranty for the battery of 8 years or 150,000 kilometers. More relevant information is as follows: 1. Battery Unit: A Tesla battery unit consists of over a dozen small packs, and each small pack is made up of more than seventy individual batteries. Moreover, the higher the electric vehicle's range and the larger the battery capacity, the more expensive the battery becomes. 2. Battery Pack: Tesla's battery pack is composed of over 7,000 18650 batteries, and the lifespan of an 18650 battery is measured by charge-discharge cycles, approximately 1,000 cycles. If charging occurs every 2 days, this translates to about 2,000 days of use, meaning the battery would need replacement roughly every 5 years.
