Electric vehicles (EVs) boast batteries located beneath the vehicle, typically in a flat section. Unlike moving parts in traditional engines, these batteries remain static, providing an extended shelf life. Manufacturers often guarantee these batteries for about eight years, or 70,000 miles.
Battery Lifespan and Degradation Rates
Over time, battery capacity might diminish, impacting the vehicle’s range. Studies suggest an average annual degradation rate of about two percent for EV batteries. However, most batteries outlast the vehicle’s usable life, ensuring longevity.
Comparing EV Battery Costs
Replacing an EV battery could cost around $10,000, similar to rebuilding an internal combustion engine. Fortunately, warranties sometimes cover failed battery packs below the guaranteed threshold. Second-hand batteries or aftermarket replacements exist, but labor costs for replacement remain the primary expense.
Testing and evaluating used EVs
Before purchasing a used EV, testing the battery’s health is crucial. Factors like extreme weather or improper usage might affect battery longevity. Similar to inspecting a traditional vehicle’s engine or transmission, evaluating an EV’s battery ensures a reliable purchase and prevents buying a problematic vehicle.
Making informed decisions
Understanding an EV’s battery life and assessing its condition before purchase is essential. While most batteries outlast the vehicle’s lifespan, ensuring a healthy battery reduces the risk of buying a vehicle with impending repair needs, akin to assessing an internal combustion engine vehicle’s critical components.
