The service life of a pure electric vehicle is primarily determined by battery performance. Typically, the vehicle lifespan reaches 10-15 years, while the battery lifespan is approximately 8-10 years. The following is a detailed analysis:
1. Core Battery Factors
● The Impact of Battery Type
The theoretical cycle life of a lithium iron phosphate battery is approximately 2,000 cycles (corresponding to 8-10 years of daily use), while the lifespan of a ternary lithium battery is slightly lower. In actual use, battery capacity should be replaced when it decreases to 60%-70% of its initial capacity.
● Warranty Policy Support
Currently, most manufacturers offer an 8-year or 120,000-kilometer warranty on their battery packs (some models have upgraded to a lifetime warranty). Users do not need to worry about battery issues during the warranty period.
2. Usage and Maintenance
● Charging Practices: Frequent fast charging or overcharging accelerates battery aging. It is recommended to maintain a charge level between 20% and 80%, with slow charging being preferred.
● Driving Style: Rapid acceleration/deceleration and driving in extreme temperatures will shorten battery life. A 10%-30% decrease in range in winter is normal, and it is recommended to enable the battery preheating function.
● Long-term parking: The battery level should be maintained at 50%-70% to avoid deep power loss and battery damage.
