- Scenario #2: This is information from the US Department of Energy website: "The advanced batteries in electric vehicles are designed for extended life but will wear out eventually. Several manufacturers of electric vehicles are offering 8-year/100,000-mile battery warranties. Predictive modeling (PDF) by the National Renewable Energy Laboratory indicates that today’s batteries may last 12 to 15 years in moderate climates (8 to 12 years in extreme climates). In addition to climate, other factors impacting battery life include driving and charging patterns, battery cell chemistry and design, and the vehicle-battery-environment thermal system." This scenario is a bit more alarming for EV's in the used vehicle market as 45percent of vehicles on the road today are over 14 years old (25percent over 20 years old). So in this scenario, any buyer of a used car over 10 years old is probably going to want the seller to replace the battery. Or the re-sale prices of older EV's will drop exponentially as they approach/exceed 10 years of age to account for the $10K+ cost of battery replacement.
This article is from 2014, probably looking at 10 years ago, and the technology is better now.
Might as well link stuff if you're going to post information from them.
