It is normal for a Tesla to lose some charge while parked. This is known as “vampire drain” or “parasitic battery drain.” Vampire drain is caused by a number of factors, including:
- Systems that remain active while the car is parked: This includes things like the computer, alarm system, and climate control system.
- Extreme temperatures: If your Tesla is parked in very hot or cold weather, the battery will need to work harder to maintain its temperature, which can lead to increased battery drain.
- Enabled features: Some features, such as Sentry Mode and Cabin Overheat Protection, can also cause increased battery drain while the car is parked.
Tesla has implemented a number of measures to reduce vampire drain, but it is still possible for a Tesla to lose up to 1% of its charge per day while parked.
Here are some tips for reducing Tesla battery drain while parked:
- Turn off Sentry Mode and Cabin Overheat Protection when you don’t need them.
- Park in a cool, shaded area to reduce the need for the battery to maintain its temperature.
- Disable features that you don’t use, such as the alarm system and climate control system.
- Keep your Tesla software up to date. Tesla regularly releases software updates that include improvements to battery management and vampire drain reduction.
If you are concerned about Tesla battery drain while parked, you can use the Tesla app to monitor your battery level and see how much charge you are losing over time.
By following these tips, you can help to reduce Tesla battery drain while parked and maximize your range.
