Do Electric Cars Lose Battery While Parked? (Checked)

Electric cars rely on batteries to store charge, and every owner looking to buy them is often worried about running out of charge.

Unlike an internal combustion engine, you can’t have someone bring a can of gas to keep you moving on the road when you run out of gas. You need to find a space to hook up your vehicle to power, which could mean towing it.

When you charge your electric car to 100% and let it sit for a few days, does it stay at 100%?

Let’s check!

Do electric cars lose battery while parked:

Electric cars lose charge when parked. However, the charge lost is significantly low. The level of charge lost varies and it’s capped at 2% to 4% a month. That means the amount of lost charge cannot affect a driver’s ability to reach their destination.

Do electric car batteries drain when not in use?

Batteries in electric cars store energy. However, they lose a small portion of the charge even when not in use. As a result, you may find yourself at a loss if you leave your vehicle sitting for too long.

Electric vehicles lose charge when idle because they have smaller 12V batteries designed to power other systems onboard.

When parked, these batteries drain energy from the main battery, resulting in loss over time. Changes in temperatures can also affect the depletion of batteries.

The battery monitoring system helps prevent you from overcharging or over-discharging your battery.

It also monitors the condition and life of the battery to maximize its longevity. This system will continuously draw power even when not in use.

Generally, unless you’re parking for several weeks or months, losing charge shouldn’t affect how far you drive and how much range the vehicle has.

How long can electric cars sit without losing power?

An electric car can generally sit for up to two hours without issues. However, other factors play a significant role, such as the battery size, weather, motor efficiency, and how much battery power is left.

In addition, if the vehicle is idling in a stop-and-go traffic jam, the battery will likelyy drain more quickly. This is due to the use of other car systems, like AC that drains power.

If you’re parking the vehicle, it’s best to turn off such systems to save battery power. A more efficient AC system will use less energy and allow the car to idle for an extended period.

Larger batteries can store more energy than smaller ones, meaning they can keep the vehicle running for a more extended period.

Do electric cars lose power when parked in WARM weather?

If the weather is hot, lithium-ion batteries–the primary source of power responsible for powering the wheels–lose charge quickly and significantly affect battery performance.

The vehicle will have to work much harder to cool the car back down when you want to drive again, which means more power loss.

Manufacturers recommend keeping the battery below 110 degrees Fahrenheit to prevent damage.

If you park the car in the sun, the combination of the blacktop and the unrelenting sun can easily heat the stagnant air under your vehicle to higher degrees.

Take caution and find shade to keep your vehicle cooler which will minimize the amount of charge lost.

Do electric cars lose power when parked in COLD weather?

In cold temperatures, your vehicle will have to continually work harder to maintain warmth to prevent it from getting too cold. As such, you will likely drain your battery charge faster than you would at a milder temperature.

If you live in a colder region, consider parking the vehicle in a warmer garage than the temperature outside to save as much charge as possible.

Extremely cold temperatures have a significant effect on the chemical reactions inside the battery, which has a direct impact on the driving range.

What happens if you park the car in an airport for weeks?

Mechanically, electric vehicles are much simpler than combustion-powered ones. They can stay parked longer without issues as they have robust motors. Experts say they last for several months without charging.

If you’re parking the vehicle in an airport for an extended period, it pays to prepare it for the long park to ensure the battery stays in good condition.

Make sure it’s properly charged to an appropriate percentage of around 50%. Charging it up to 100% and not driving the vehicle can cause massive damage to the battery cells.

This is also true if you keep the battery charged at a low percentage for a long time. It is recommended not to leave your car parked with a battery percentage lower than 20%.

You also want to consider the weather your vehicle is exposed to if it has to be parked in an airport for a while.

Depending on how long you intend to park the car, have someone move it from one spot to another to avoid tire damage.

Electric vehicles are quite heavy, and constant pressure can result in flat tires. You can also inflate them to your manufacturer’s recommendation to prevent any damage in case they get deflated.

Do Teslas lose power when parked for a day or two?

Teslas consumes around 1% of battery charge per day when parked. The consumption can be higher sometimes depending on how you use the vehicle, how long you park, and the weather in your area.

Tesla recommends deactivating various features such as the Sentry Mode, preconditioning, Keep Climate On, and other aftermarket equipment when the vehicle is not in use.

Tesla notes that its batteries can be extremely affected by cold and hot temperatures. However, the impact is more noticeable in cold weather. High voltage batteries are regulated to maintain battery temperature within optimal boundaries.

Final Thoughts

Electric vehicles have powerful batteries that can last quite long if well maintained. That means how they lose charge depends on your actions.

Having proper charging habits, parking in the shade, and leaving them parked in the right battery percentage are some of the best ways to keep the vehicle in great shape for a long time.

If you’re planning to park the car and not use it for some time, don’t just leave it unattended. Have someone monitor the charge, check the tires and review the vehicle’s overall condition if you’re away to prevent damage.
