Renting an EV: Charge Return Rules, Fees and Tips

By RentRight Team · Published October 12, 2026 · 9 min read

TL;DR: Electric rentals have a charge rule instead of a fuel rule. Avis and Budget want at least 70% back and charge $35 below that (plus another $35 under 10%). Hertz bills by the kWh if you come back well below your pickup level. Photograph the dashboard battery percentage at pickup and return, and read the EV section of your agreement before you drive off.

More rental counters now hand out Teslas, Polestars and other electric cars, sometimes as an upgrade you did not ask for. Driving one is easy. The part that trips people up is the return. There is no gas gauge to top off, the rules are written in battery percentages, and each company handles a low battery a little differently.

This guide pulls together the published EV policies from the major U.S. rental companies, explains the fees you can run into, and gives you a simple routine so you never pay for electricity you did not use.

How EV Return Rules Differ From Gas

With a gas car, the rule is usually "return it full or pay a refueling charge." With an EV, companies set a target battery level instead of asking for 100%. There are good reasons for that: charging the last stretch to 100% is slow, and batteries last longer when they are kept between roughly 20% and 80%. Hertz says as much in its own EV guidance.

In practice, EV policies come in two flavors:

A fixed threshold: bring the car back at or above a set percentage (Avis and Budget use 70%), or pay a flat fee.
Match your pickup level: bring it back close to the percentage you started with, or pay for the missing energy plus a service fee (this is how Hertz describes its current approach).

Either way, a second, steeper penalty usually kicks in if the battery is nearly empty, because a deeply drained car takes longer to turn around and can strand the next renter. And if the car runs completely flat, you can also be on the hook for a tow.

Never assume an EV is "return at any level." Unless you bought a prepaid charging option at the counter, there is almost always a target percentage in your agreement.

Charge Return Rules by Company

This table summarizes what each company publishes for U.S. rentals as of October 2026. Where a company does not publish a number we could confirm, it says "check your agreement." Policies can vary by location and change without much notice, so treat the rental agreement you sign as the final word.

Company	Return target	Fee if below target	Very low battery	Tesla Supercharging
Avis	At least 70%	$35	Extra $35 under 10% ($70 total)	Billed at cost plus a 2.3% admin fee, may post after your final invoice
Budget	At least 70%	$35	Extra $35 under 10% ($70 total); towing billed to you if the car is depleted	Billed at cost plus a 2.3% admin fee
Hertz	Close to your pickup level (Hertz says you never need to return it above 75%)	EV Service Charge: energy billed per kWh plus a service fee; rates vary by location	Check your agreement	Billed back to your rental, idle fees included
Dollar / Thrifty	Posted terms: 70%, minimum 10%	$35 (waived if picked up under 75%)	$25 undercharge fee under 10%	Billed back to your rental, idle fees included
Enterprise / National / Alamo	Check your agreement	Check your agreement	Check your agreement	Check your agreement

What Each Company Says

Avis and Budget

Avis and Budget publish the clearest EV rules of any major brand, and the two match. Avis says it will hand over the car with at least 70% charge, and both brands require at least 70% back. Return it between 10% and 70% and you pay a $35 charging fee. Drop below 10% and a second $35 "low charge" fee is added, for $70 in total. You can charge at any public or private station, but you pay for that energy and for any sign-up those networks require.

Two more details are easy to miss. First, all EV equipment, including charging cables and key cards, has to come back with the car, and the replacement cost of anything missing is billed to you. Avis also notes its damage waiver does not cover that equipment. Second, Budget's terms say that if the battery is drained and the car cannot be driven, it will be towed to the renting location at your expense.

Hertz

Hertz runs one of the largest EV fleets and describes three ways to handle charging. You can recharge it yourself to roughly the level you received it, which costs only whatever you pay at the charger. You can buy the EV Purchase Option at pickup, which prices the energy in the battery near local charging rates plus a small fee and lets you return at any level (unused charge is not refunded). Or, if you skip both and come back more than about 5% below your pickup level, Hertz recharges it and bills an EV Service Charge: the same energy rate with a higher fee on top. Hertz says the prepaid option is always cheaper per kWh than the service charge, and that charging yourself is generally cheapest of all.

Hertz aims to hand out EVs at about 80% and says you never have to bring one back above 75%. It does not publish nationwide dollar amounts for either option, because prices vary by location, so check your agreement for the exact rate.

Dollar and Thrifty

Dollar and Thrifty are owned by Hertz, and Dollar's general policies page includes a set of Hertz electric vehicle rental terms with flat fees: a target of 80% at pickup, a required minimum of 10% at return, an optional $35 Charge Purchase Option that lets you return at any level above 10%, a $35 recharge fee if you return it below 70% (waived if you picked it up below 75%), and a $25 undercharge fee below 10%. The same terms ask you to cap Tesla charging at 90% and to return the Tesla charging kit and J1772 adapter. These flat-fee terms differ from the per-kWh approach on Hertz's own site, which is one more reason to read the EV section of the agreement you actually sign.

Enterprise, National and Alamo

Enterprise Holdings does not publish a single U.S. EV fee schedule that we could verify. Reporting on National's rental terms describes a charge when the car comes back with less battery than it had at pickup, without a published amount. Ask the counter agent two questions before you leave: what level do you need to return it at, and what is the fee if you miss it? Then check that the answer matches the EV section of your agreement.

Sixt

Sixt's help center explains that each charging network sets its own pricing and that rates can depend on session length, time of day and energy used. The Sixt app's charging tab shows current rates, which may differ from the price on the station itself because of Sixt's agreements with network owners. Sixt does not publish a U.S. return threshold or recharge fee we could confirm, so check your agreement.

Tesla Superchargers, Idle Fees and Adapters

If you rent a Tesla, the Supercharger network is usually the easiest way to charge. You do not pay at the stall. The session is billed to the rental company, which passes it on to you. Avis and Budget add a 2.3% administrative fee and warn that these charges may land on your card after your final receipt, so do not be surprised by a late, small charge.

Idle fees are the trap. Tesla charges congestion fees when a busy site has cars sitting at 80% or more, and after a session ends. Tesla waives the first five minutes, then bills until the car is moved. Rental companies pass these fees through, so set a phone alarm and move the car as soon as it has enough charge.

Non-Tesla rentals can use many Superchargers too. Tesla says cars with a NACS port need no adapter, while other EVs need an NACS DC adapter from Tesla or the car's maker; third-party adapters are not allowed. You pay through the Tesla app with your own payment method, so keep those receipts. Ask whether your rental includes an adapter before you count on Superchargers.

Teslas at non-Tesla chargers: Most public Level 2 stations use the J1772 plug. Hertz's terms list a J1772 adapter as part of the equipment that comes with its Teslas. Check the trunk or frunk for it at pickup, and make sure it goes back with the car, since missing equipment is billed at replacement cost.

Finding Chargers and Planning Range

Plan the last charge first. Find a fast charger within 10 to 15 minutes of the return location before you need it. Airport-area chargers can be busy on Sunday evenings and holiday weekends.
Use a station map. The U.S. Department of Energy's Alternative Fuels Station Locator, PlugShare and the car's built-in navigation all show chargers. Tesla navigation will route you through Superchargers automatically and precondition the battery so it charges faster.
Budget for real-world range. Highway speeds, cold weather, heat and hills all cut range compared with the sticker number. Leave a buffer of at least 20% on longer drives.
Fast charging slows near the top. DC fast charging is quickest at low and middle battery levels. Charging from 20% to 70% is usually much faster than going from 70% to 100%, which works in your favor with a 70% return target.
Check your lodging. A hotel with Level 2 chargers can refill the car overnight while you sleep, often at little or no cost.
Download the apps early. Many networks need an account and a payment method. Setting them up at home beats doing it in a parking lot with a weak signal.

Document the Charge Level at Pickup and Return

Recharge disputes almost always come down to one number: the battery percentage. Make that number easy to prove.

At pickup, photograph the dashboard showing the battery percentage, estimated range and odometer. On a Tesla, switch the display from miles to percent first.
Compare it to the paperwork. If the agreement or app shows a different starting level than the screen, ask the agent to correct it before you leave.
Photograph the charging cable and adapters in the car, so you can show they came with it.
At return, repeat the dashboard photo in the return lane with the car in park, so the time and location are clear.
Keep charging receipts from the last station, which show the time and energy added.

ReturnItRight walks you through a return checklist so you leave with proof of the car's condition, mileage and charge level.

If You Get Hit With a Recharge Fee

Check your final receipt for charging fees, "low charge" fees, Supercharger pass-throughs and idle fees. If something does not match your photos, ask the location or customer service to reverse it and send the dashboard photo from your return. Most mistakes, such as a car checked in after it sat and drained, or a starting level recorded wrong, get fixed quickly when you have a timestamped photo.

If the company will not budge, put your dispute in writing and keep a copy. Our Receipt Checker can help you spot unexpected line items, and DisputeItRight can help you draft a clear dispute letter. A credit card dispute is the backstop if the company does not respond.

Frequently Asked Questions

Do I have to return an electric rental car fully charged?

Usually not. Avis and Budget require at least 70%, and Hertz says you never need to return one above 75%. Other companies may ask you to match your pickup level, so check your agreement.

What happens if I return an EV rental below the required charge?

At Avis and Budget you pay a $35 charging fee below 70% and another $35 below 10%. Hertz bills the missing energy per kWh plus a service fee. Other companies set their own fees, so check your agreement before you leave the lot.

Who pays for Supercharging in a rental Tesla?

You do. Supercharger sessions are billed to the rental company and passed on to you. Avis and Budget add a 2.3% administrative fee, and idle fees for leaving the car plugged in are passed through too.

Can I use a Tesla Supercharger with a non-Tesla rental?

Often yes. Tesla says NACS-equipped cars need no adapter and other supported EVs need an NACS DC adapter from Tesla or the automaker. You pay through the Tesla app with your own card.
