Checking Battery Life on Used EVs: What You Need to Know
When it comes to buying a used electric vehicle (EV), one of the biggest concerns for potential buyers is the battery life. Unlike checking the battery life on your phone, checking the battery life on an EV can be a bit more complicated and less straightforward. This complexity can make buyers hesitant about purchasing a used EV.
It’s important to note that EV battery longevity has significantly improved in recent years. On average, EV batteries lose about 1.6% to 2.0% of their capacity each year, regardless of whether they use nickel-manganese-cobalt or lithium-iron-phosphate chemistry.
While you can use OBD-port readers to assess an EV’s battery health, these readings may not always be entirely accurate. Factors like battery temperature, previous cycling, and the device’s accuracy can affect the results. For a more reliable assessment, consider buying from a reputable dealer who can provide a detailed report on the car’s battery health.
One way to gauge a used EV’s battery health and potential range is to look at the range readout on the car’s dashboard. However, keep in mind that this figure can be influenced by previous driving habits, and some models may overestimate range when fully charged. Calculating range based on long-term efficiency can provide a more realistic estimate of real-world range.
For insights into a used EV’s realistic range, consider reaching out to owners’ clubs for feedback. While lower-mileage EVs that have not been rapid-charged frequently may seem like a safer bet, high-mileage cars can also surprise you with their battery health and range potential. In fact, some well-used EVs, like a nine-year-old Tesla Model S with 260,000 miles on the clock, can still retain a significant portion of their original battery capacity.
Ultimately, when buying a used EV, it’s essential to take battery health into consideration. By doing your research, consulting reputable dealers, and getting feedback from owners’ clubs, you can make a more informed decision and potentially find a high-quality used EV with plenty of life left in its battery.
