![]() There are anecdotal stories of Tesla batteries lasting well over 300,000 miles and Prius owners pushing their hybrids to well over 500,000 miles, but the data at this time is limited. There's no hard-and-fast rule for how long a traction battery can last. How a device is charged and how quickly that energy is depleted also determines how long a battery will last. This is not unique to EVs - anything with rechargeable batteries (smartphones, Bluetooth speakers, etc.) will suffer the same fate after multiple charging cycles. How long do traction batteries last?Īll batteries, regardless of design, will eventually experience diminished capacity and require replacement. Lithium-ion batteries are the most common type of battery module found in these battery packs. Traction batteries are typically assembled in a series of battery modules that are connected to make a battery pack. Most EVs and hybrid vehicles also have auxiliary, 12-volt batteries (like those used in gas-powered cars) to power low-voltage systems throughout the vehicle, but don’t confuse these small batteries with the traction batteries that make these cars go. Instead, they use huge traction batteries to power the multiple electric motors in each vehicle. Electric vehicles don’t have any internal combustion engines.Plug-in hybrid vehicles take this concept a bit further by providing a slightly larger EV battery that can provide 15 to 42 miles of total range before the internal combustion engine kicks in to charge the traction batteries and provide forward motion.Hybrid vehicles have traction batteries that work in conjunction with a small internal combustion engine to propel the vehicle forward and recharge the battery.EV battery repair is a growing industry that may help you avoid the high cost of a replacement, but it’s not commonly available yet.īoth hybrid vehicles and EVs use high-voltage batteries known as “traction” batteries, but they use them in different ways:.Sourcing a replacement EV battery from anyone but your car’s manufacturer is nearly impossible, which is the main reason replacement costs are so high.It’s hard to pinpoint how long EV batteries will last, but most have a life span between eight and 15 years.All EV batteries will eventually fail to hold a charge and require replacement.Keep reading to find out what an EV battery is, how long it lasts, how to know if yours is going bad, what it might cost you to repair or replace yours and whether a warranty can help. ![]() to see how much an EV battery replacement costs for different vehicles, and the average results ranged from $4,489 all the way to a staggering $17,658. We reached out to five mechanics and technicians from different parts of the U.S. Although the powertrains in hybrid and electric vehicles (EVs) require less maintenance than internal combustion engines, the high-voltage batteries that power their electric motors can fail eventually.
