Buying a used EV in the US: what to check

Used electric cars in the US have fallen a long way in price, which makes them excellent value — provided you check the things that decide a used EV's worth. Battery condition and warranty position matter far more than odometer reading.

Battery health

Ask for a state-of-health readout or an independent battery test. Hot-climate cars and cars that lived on DC fast charging tend to show more degradation than the average.

• Compare indicated full-charge range against the original EPA figure
• Ask how the car was routinely charged and to what state of charge
• Climate history matters: sustained heat is harder on packs than cold

Warranty transfer

Federal rules require an eight-year or 100,000-mile battery and electric powertrain warranty on new EVs, and some states require longer. These normally transfer to later owners, but capacity thresholds and exclusions vary.

• Confirm remaining battery and powertrain warranty in years and miles
• Check the capacity threshold that triggers a claim
• Check whether any state-extended warranty terms apply

Connectors and charging

Confirm whether the car is NACS or CCS, which adapters are included, and its maximum DC charging rate — older cars can be much slower on a fast charger than current models.

History, recalls and software

Run a history report, check open recalls including battery-related campaigns, and confirm which connected services and over-the-air features transfer to a new owner.

Before you commit, run the car through our used EV battery health and range checker: it estimates state of health from age and mileage, tells you whether the battery warranty is still live, and gives you a summer and winter range figure to sanity-check against the seller's claims.
