How Many Years Can a New Energy Vehicle Last?
1 Answers
New energy vehicles can last 8 to 10 years. The following is an introduction to the service life and factors affecting it: Service life of pure electric vehicles: The service life of the power battery in a pure electric vehicle is generally 8 to 10 years, and manufacturers also provide an 8-year warranty period. During the warranty period, there is no need to worry about battery issues. The cost of the power battery in a pure electric vehicle is very high, accounting for 40% to 50% of the total vehicle cost. The expensive battery cost is currently the biggest drawback of pure electric vehicles. After about 8 years of use, the battery will need to be replaced. The high replacement cost makes it more economical to replace the vehicle rather than the battery. Factors affecting the lifespan of electric vehicles: It depends on the motor. Different drive motors have vastly different costs. If a DC brushed motor is used, the vehicle's power source can directly supply the motor, and a thyristor-based controller is used for chopper speed control. Among the commonly used batteries, nickel-cadmium batteries have a wet shelf life of 2 to 3 years, lead-acid batteries 3 to 5 years, lithium-ion batteries 5 to 8 years, and zinc-silver batteries the shortest, only about 1 year. Additionally, battery performance includes: low-temperature performance, overcharge tolerance, safety performance, etc.
