How Long Does the Battery of a Hybrid Electric Vehicle Last?

[Kiara]

Hybrid electric vehicles use power batteries that are different from the lead-acid batteries used for starting, lighting, and in-car electricity. These can generally be categorized into three types: ternary lithium batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries. The first two types belong to lithium-ion batteries. Ternary lithium batteries have a cycle life of less than 1,000 cycles, while lithium iron phosphate batteries last around 2,000 cycles. When used in hybrid electric vehicles under normal conditions, they can typically last about 10 years or 200,000 kilometers. The lifespan of each battery type is as follows: 1. Lithium-ion batteries: Currently, ternary lithium batteries are designed to achieve around 20% capacity loss after 1,000 cycles. According to passenger vehicle standards, after 5 years of use, the remaining battery capacity can be expected to be between 60% and 80%. Lithium iron phosphate batteries have a cycle life of approximately 2,000 cycles, and when used in hybrid electric vehicles, they can generally last about 10 years or 200,000 kilometers without much difficulty. 2. Nickel-metal hydride batteries: Generally, nickel-metal hydride batteries have a cycle life of about 500 cycles.
