Where free charging still exists
Free charging is patchy, and offers change often. The usual places:
- Workplaces. Some employers offer free Level 2 charging in their parking lots as a perk.
- Retail and destinations. Some stores, malls, hotels, parks and attractions provide free Level 2 chargers for customers or guests.
- Municipal chargers. Some cities and towns offer free charging in public lots, sometimes with parking fees or time limits.
- Dealerships. Some dealers let customers, or anyone, use their chargers.
- Vehicle purchase offers. Some automakers have bundled a period or amount of free public charging with new cars. Terms vary widely, so read the fine print for your car.
Charging-network apps and in-car maps usually let you filter by price. The listing is only as good as its last update, so check before you rely on it.
What free charging is worth to you
The value depends on what you would have paid otherwise. If the alternative is home charging, you save your home rate. If the alternative is a public charger, you save more. The table shows yearly value for a 33.5 kWh/100 mi EV driven 13,500 miles, by share of energy that comes free.
| Share of charging free | vs home, Nevada | vs home, U.S. average | vs home, Hawaii | vs public at $0.45/kWh |
|---|---|---|---|---|
| 10% | $57.53 | $82.13 | $213.37 | $203.51 |
| 25% | $143.82 | $205.32 | $533.43 | $508.78 |
| 50% | $287.63 | $410.65 | $1,066.86 | $1,017.57 |
| 100% | $575.26 | $821.29 | $2,133.72 | $2,035.13 |
A free 10–80% session on a typical 294-mile EV delivers roughly 68.9 kWh, worth about $12.52 at home prices, $32.53 in Hawaii or about $31.02 at the example public price. The public figure is approximate, because public chargers bill for delivered energy rather than wall energy.
The catches
- Time. Most free chargers are Level 2. At 7.68 kW, adding 100 miles takes about 4 h 22 min. Free charging makes sense where you would park anyway, not as a trip.
- Driving to it. A detour costs energy and time. A few miles out of your way can eat much of the value of a short session.
- Parking fees and time limits. A "free" charger in a paid lot is not free, and many sites limit how long you can stay.
- Availability. Free chargers are popular and can be occupied or out of service. Do not plan a trip around one.
- Your car's onboard charger. On AC chargers, your car's onboard charger caps the speed. See onboard charger limits.
- Etiquette. Move the car when it is done so the next driver can use the spot. Many sites expect you to leave once charging finishes, even if the parking itself is unrestricted.
Free charging vs cheap home charging
In low-price states the value of free charging is modest. In Nevada, where home power averages 12.72¢/kWh, free charging for a quarter of your driving is worth about $143.82 a year. The same share in Hawaii is worth about $533.43. If a free charger costs you an extra half hour each visit, that difference decides whether the trade is worth it.
How to count it in your budget
Estimate how many kWh you get free each month, subtract that from your home estimate and price the rest at your own rate. The charging cost calculator gives the full home cost to start from, and the state pages show the average price where you live. If you are a renter without home charging, free workplace or destination charging can matter a lot more; see EV charging for apartment renters.
