As more used electric vehicles become available, consumers may be wondering about the process of purchasing one. Should a mechanic check the vehicle first? What kind of parts must the buyer inspect? What about the miles? Are they an important metric as in gas cars? Is the battery’s life significant or just the number of usages?
To learn more, AAA turned to Matt Lamontagne, who specializes in electric and hybrid vehicles as the owner of Leo & Sons Auto Repair in Lawrence, Massachusetts. What should those shopping for used EVs keep top of mind?
“The most important aspect of any used EV is the state of health of its high voltage battery,” Lamontagne said. “The HV battery is the lifeblood of the vehicle. Its capacity and health dictate the car’s usability. The most important thing when buying a used EV is to have it pre-inspected by a qualified professional.”
Lamontagne offers more advice to guide buyers in the process of shopping for used EVs.
Where is the best place to buy used EVs? At a brand-name dealer, at an independent used car dealer, or from a private seller?
The best place to buy a used EV would be from the original owner. The owner would hopefully be able to provide some history of how the high voltage battery has been treated. Frequent direct current fast charging is hard on the high voltage battery and causes degradation. If the original owner said they had a long commute and DC fast charged daily, it’s likely the HV battery has a lower state of health.
What should buyers look for in a used electric vehicle? What is the difference from buying a used gasoline car?
The odometer reading is no longer the most important metric when shopping for a used EV. The high voltage battery’s state of health, and ultimately, the rang capability are the most important things to check. The buyer should also check the normal things like tires, brakes and accident history.
What’s the right “age” for a used EV? How many miles should buyers look for?
Five years old and newer. EV technology has made large advancements in the past five years. Older EVs can still be a good used vehicle but need to be checked closely prior to purchase. The mileage still carries some weight, but a low mileage car can have a low SOH (state of health) battery.
What are the advantages and disadvantages of buying a used EV?
The advantages of buying a used EV are the tax incentives and promotional programs that are available. EVs are also fast, fun and full of cool tech. The disadvantages are the lifestyle change that comes with EV charging. Many people adapt quickly to the differences when they are able to charge their EV at home. EV repair is typically more expensive because of the expensive high voltage parts that break. That being said, EVs typically break down less often.
What about hybrids, is it the same process?
Hybrids are similar in that they have an HV battery that needs to be checked prior to purchase. Hybrids are different in that they have an internal combustion engine and several emissions control systems that need to be checked.
AAA’s Recommendation: Whether you own an electric vehicle or a gas-powered car is up to you – and you should consider lots of factors in making that choice. No matter what type of vehicle you’re choosing, we recommend visiting a dealership, test driving one, and asking as many questions as possible to make an informed decision.
