What to Check Before Buying an Electric Vehicle

An EV's spec sheet only tells part of the story. Here's what actually matters once you own one.

Real-world range vs. the official rating

The official range figure is measured under fixed test conditions, but real-world driving β€” temperature, speed, climate control use, cargo weight β€” often brings that number down. Test drives and real owner reviews give a more honest sense of what to expect day to day.

Check your home charging situation first

Confirm whether you can install a home charger where you park, and if you live in an apartment or condo, check the building management's installation process and whether there's enough spare electrical capacity β€” sorting this out before delivery avoids a frustrating gap between owning the car and being able to charge it conveniently.

Check incentive eligibility and remaining funds

Government or local EV incentives vary by country, region, and even by specific model, and funding pools can run out partway through the year. Confirming your model qualifies and that funds are still available through your local transportation authority before you commit avoids an unpleasant surprise at purchase time.

Check battery health (SOH) on a used EV

On a used EV, mileage alone doesn't tell the full story β€” ask for the State of Health (SOH), a percentage showing how much of the battery's original capacity remains. A lower SOH means less real-world range than a new version of the same car, so requesting a diagnostic report or inspection certificate is a smart precaution.

Compare charging costs and electricity plans

Home electricity rates and public charging network pricing can differ substantially, so your actual running cost depends heavily on where you'll usually charge. Comparing plans against your expected charging pattern before buying gives a more realistic cost picture.

Factor in depreciation and resale value

Because battery technology keeps improving and new models arrive frequently, some EVs depreciate faster on the used market than comparable gas cars. Whether you plan to keep the car long-term or trade it in a few years should factor into your choice between buying new, buying used, or leasing.

The spec sheet is a starting point, not the answer

Range, price, and features on paper matter, but they don't capture charging convenience, incentive timing, or how a specific used unit's battery has held up β€” all of which shape the actual ownership experience more than the brochure numbers do.

Do the homework before, not after, delivery

Most EV regrets trace back to skipping one of the checks above β€” a charger that turns out to be harder to install than expected, an incentive that ran out, or a used battery in worse shape than assumed. A little research before signing saves a lot of frustration afterward.

Frequently Asked Questions

Is public charging enough if I can't install a home charger?

It's workable, especially if reliable fast chargers are nearby, but expect higher costs and more planning around charging stops compared to charging overnight at home β€” factor that into your decision.

What SOH percentage should worry me on a used EV?

There's no single universal cutoff since it depends on the model and battery chemistry, but a noticeably lower SOH than similar-mileage listings, combined with no diagnostic history, is worth negotiating on or walking away from.
