What is the lifespan of automotive lithium batteries?
2 Answers
The lifespan of lithium-ion batteries in ordinary electronic products is approximately 5 to 20 years, with an average of 8 years. However, with current technological capabilities, the service life of lithium-ion batteries in electric vehicles is only about 3-5 years. Battery capacity: When an electric vehicle's battery capacity degrades to below 80% of its initial capacity, the vehicle's driving range will significantly decrease. When the capacity drops below 70%, the battery must be replaced. For many current pure electric vehicles, battery costs account for about 40% of the total vehicle cost, meaning replacing the battery is equivalent to replacing nearly half of the car.
The average lifespan of automotive lithium batteries is around 8 to 12 years, or a driving range of approximately 100,000 to 150,000 miles, but this depends on various factors. When using the vehicle, I pay attention to the battery's cycle count, which can generally withstand 1,000 to 2,000 full charge cycles. If deep discharging or fully charging frequently occurs, the lifespan will shorten. Temperature is key: high summer temperatures can accelerate battery degradation, so I try to avoid parking in direct sunlight for extended periods and use a garage or car cover instead. Charging habits are also important—using slow charging mode as much as possible and minimizing fast charging helps, with maintaining the charge level between 20% and 80% being optimal. Battery health monitoring is convenient too, as many car models have apps that display remaining capacity; a drop of more than 10% warrants a check. Regular battery maintenance, avoiding frequent hard acceleration or towing heavy loads, can effectively extend usage time.
