How to Store an Electric Car for a Season or Longer

Updated Jul 2026 · 6 min read

Why an EV needs a different storage plan

An electric car sits in storage differently than a gas car. There's no fuel to stabilize and no engine oil going stale, so the checklist you'd use for a classic or a daily driver only half applies. The battery becomes the thing you're really protecting.

A lithium-ion pack slowly loses charge even when the car is switched off and locked. Leave it in the wrong state for a few months and you can come back to a car that won't wake up. If you're parking an EV at a storage facility for the winter, a long deployment, or an extended trip abroad, a handful of decisions before you walk away will save you a headache later.

Set the battery charge before you leave

The high-voltage battery doesn't like sitting completely full or nearly empty for long stretches. Most EV makers suggest leaving the car at a middle charge level rather than topped off or run down toward zero. The exact figure differs by model, so check your owner's manual for the range your manufacturer recommends for long-term parking, and follow that over any rule of thumb you read online.

If your car lets you set a charge limit, use it. Many EVs have a setting that caps how high the battery fills, which is handy if the car will be plugged in while you're gone.

Decide whether to keep it plugged in

What you do here depends on the facility. Some storage sites have power at the space; many don't.

If there's an outlet you can use, the simplest approach is often to leave the car connected with a charge limit set, so it tops itself up gently and keeps the systems alive without overfilling the pack. Ask the facility whether leaving a car on a charger unattended for weeks is allowed, since policies vary.

If there's no power, don't leave the car at a full charge and don't let it drop low before you park it. Set the middle charge your manual calls for, then let it rest. Plan to come back and check on it if you'll be away long enough that the charge could drift out of a safe range.

The 12-volt battery is the one that quietly dies

Here's the part that catches EV owners off guard. Alongside the big traction battery, almost every electric car still has an ordinary 12-volt battery running the door locks, the computer that boots the car, and the systems that let you "start" it. That small battery can drain while the car sits, and if it goes flat you may not even be able to open or power up the vehicle to charge the main pack.

A couple of ways to handle it:

• Keeping the car plugged in usually lets it maintain the 12-volt battery on its own, since the car tops it up from the main pack.
• If the car won't be connected to power, ask a dealer or check your manual about using a compatible battery maintainer on the 12-volt battery. Not every EV supports the same approach, so confirm the right method for your model before hooking anything up.

Don't assume the small battery takes care of itself. It's the most common reason a stored EV refuses to respond when the owner returns.

Protect the tires and the body

These concerns are shared with any stored car, EV or not. Tires lose air over time and can develop flat spots where they've been pressed against the floor for months. Inflate them to the pressure on your door-jamb sticker before you park, and if the car will sit a long while, ask the facility whether they can help reposition it occasionally or whether tire cradles are an option.

An indoor space shields the paint, glass, and rubber seals from sun and weather far better than an open lot. A climate-controlled unit adds protection against the swings in temperature and humidity that are hard on electronics and interiors. If you're choosing between options, our guide on indoor versus outdoor car storage walks through the trade-offs.

Give the car a wash and let it dry fully before storing it, and crack a window slightly only if the unit is secure and dry, to cut down on stale cabin air.

Choose a facility that fits an electric car

Not every storage site is set up for an EV, so ask a few pointed questions when you're comparing them:

• Is power available at the space? This single answer shapes your whole storage plan.
• Is the unit indoor or climate-controlled? Steadier conditions are kinder to the battery and the electronics.
• What are the access hours? You may want to look in on the car and check its charge, so easy access matters more with an EV than with a gas car you can leave for months.
• What's the security setup? Gated entry, cameras, and good lighting protect a car that's often worth more than what's parked around it.

Many facilities that already handle vehicle storage will happily accommodate an EV once they know what you need. It's worth saying up front that you're storing an electric car so they can point you to the right space.

Waking the car back up

When you return, don't just hop in and drive. Check the tire pressures and bring them back to spec, since they'll almost certainly have dropped. Confirm the 12-volt system powers everything up normally. Then give the main battery a proper charge before any real driving, and let the car run through its usual startup checks.

A short, gentle first drive lets you listen and feel for anything off before you head out on the highway. Treat the first trip as a shakedown rather than a road trip, and your EV should pick up right where it left off.

Storing an electric car isn't harder than storing a gas one. It's just different, and the difference lives almost entirely in the battery. Get the charge right, keep the 12-volt battery alive, and pick a space that suits the car, and you can walk away without worrying.
