A 900-volt pack does not sit idle. It manages its own temperature, draws on its own reserves, and cares a great deal about the state of charge you left it at.
Storing an electric car is not storing a petrol car with the fuel section deleted. A parked Lucid Air is still awake: the thermal management system is protecting the high-voltage pack, the telematics are reporting, and both are drawing power. In a valley that reaches 115°F, that system has to work hard, and everything it does costs range and cycle life. REVCity Auto Storage, 7185 Bermuda Rd, Las Vegas NV 89119. Call 725-272-1803.
Lithium-ion cells degrade fastest at the extremes of their charge window, and the damage compounds with temperature. Stored at a high state of charge in heat, the cathode sits under sustained electrochemical stress and calendar ageing accelerates. Stored near empty, you risk the pack dropping to a level where the management system will not permit a normal charge at all.
Roughly half. Set the charge limit to 50 to 60 percent before the car goes in, and store it somewhere the ambient temperature is not fighting you. The general protocol is in storing an EV battery long term.
The Air’s advantage is also what makes ambient temperature matter more than owners expect: a 500-mile-class pack is a large thermal mass, and keeping a large thermal mass within its window in 115°F ambient means the cooling system runs. At 50 to 70°F it essentially does not have to.
This surprises people. The high-voltage pack can be in perfect health and the car still completely dead, because the low-voltage system is what wakes everything up — contactors, computers, door handles. On many EVs the 12-volt battery is topped up from the main pack only when the car decides to do it, and a car left untouched for months can flatten the small battery while the big one sits at 55 percent.
A flat 12-volt on a modern EV is not a jump-start-and-go situation. Door handles may not present, the charge port may not open, and access to the 12-volt terminals is often awkward by design. Every bay at REVCity runs a maintainer on the low-voltage system, which is the single most useful thing you can do for a stored EV and the thing most storage arrangements ignore entirely.
The distinction between a maintainer and an old trickle charger matters here as much as on a combustion car — constant current cooks plates, float charging does not. The chemistry differences are covered in AGM versus lithium.
The Air’s Glass Canopy roof is one of the largest single pieces of glass fitted to a production car, and it sits directly over the occupants. It is coated and it is effective, but glass area is glass area: parked in open Las Vegas sun under a UV index of 10 to 12, the cabin behind it heats faster and further than a metal-roofed car’s, and it heats the interior materials from above rather than through the windscreen alone.
None of the interior damage is insurable. Gradual heat and UV deterioration is excluded from essentially every policy as wear, so preventing it is the only available strategy.
If the Air is a second car you use a few weeks a year, the pattern is covered in second-home car storage. For multi-month stays, long-term storage in Las Vegas sets out the rest.
Battery degradation gets discussed as if it were one thing. It is two, and only one of them applies to a car that is not moving.
Calendar ageing is the one nobody can avoid entirely, but its two controllable inputs are exactly the two that storage decides: the temperature the car sits at, and the state of charge you left it at. Get both right and a long sit costs the pack very little. Get both wrong — 100 percent charge in an uncooled Las Vegas garage through July — and you are paying for the storage decision in range for the rest of the car’s life.
The Air runs a higher-voltage architecture than most of the field and a physically large pack to reach its range figures. A larger thermal mass takes longer to bring back into its window once it has soaked, which makes stable ambient temperature worth more here than on a smaller-battery car.
If the car is stored seasonally rather than long-term, the arrive-and-drive pattern is covered in the snowbird guide.

Between 50 and 60 percent. Lithium-ion cells degrade fastest at the extremes of their charge window and the effect compounds with heat, so storing at 90–100 percent in a hot building accelerates calendar ageing. Below 20 percent risks vampire drain walking the pack toward a deep-discharge state.
It can, and that is what actually strands you. The high-voltage pack can be perfectly healthy while the low-voltage system is flat, leaving door handles and the charge port unresponsive. Every REVCity bay runs a maintainer on the 12-volt system, which most storage arrangements do not provide.
Sustained high ambient temperature is the main driver of calendar ageing in a lithium-ion pack, and at 115°F the thermal management system runs to keep the pack in its window — consuming energy and cycling components. Holding the car at 50–70°F means that system has nothing to fight.
In a temperature-controlled building it matters far less than it does outdoors, because the pack is not fighting ambient heat. We will set it up either way. What matters more is not leaving it at a high state of charge and keeping the 12-volt system maintained.
It increases the thermal and UV load on the cabin compared with a metal roof, and it loads the upper dash and shoulder surfaces directly rather than only through the windscreen. In an enclosed building with no ultraviolet reaching the car the question disappears entirely. Call 725-272-1803.
