The most crucial part of a Tesla is the battery. One advantage Tesla has over the competition is their excellent battery regulation. Batteries in a Tesla last longer when compared to the competition due to Tesla’s excellent battery monitoring.
There are four major contributors that lead to lithium-ion battery degradation, which we would like to minimize. The first two we don’t have much control over, which are the age of the battery and the number of charge cycles (the number of times the battery has been charged and discharged).
However, the last two, we do have control over. Lithium-ion batteries don’t like to remain in a very high, or very low state of charge. That doesn’t mean we should never charge to 100% or use it down to 5%, but it’d be wise to minimize those occurrences. The last thing is the temperature of the battery. For the most part, Tesla handles this automatically. The batteries are heated and cooled to stay in a healthy temperature range without you ever knowing, even if the car is off. The car will also limit power when driving if necessary.
If you’re going on vacation and leaving your car at home or at the airport here are some things to consider.
If you can leave your car plugged in while at home or the airport
If you can leave your car charging, then absolutely do this, this will make things much easier and let the car control everything itself without you ever having to worry about it
Lithium-ion batteries are best stored at around 50% of charge, so set your charge level in the Tesla app or the car to 50%. The car will automatically use some energy when needed to cool or heat the battery, and it’ll get this power directly from the power source instead of Tesla’s batteries.
Keep the car in a garage or under a cover if possible, this will help keep your car away from extreme elements such as snow, ice and heat. In general, this is just good practice.
If you can not leave your car plugged in at home or the airport
If you can not leave your car plugged in while going on vacation there are several more things we need to account for to prevent any possible issues longer term.
If the weather is extreme, whether it’s extremely cold or hot and you can not park in an isolated area and are going away for more than two weeks, then you may want to consider a different mode of transportation. If the car battery is drained completely, it could lead to battery damage since the car can no longer keep the batteries at an ideal temperature and it’ll no longer be able to protect itself from harsh weather.
If you're going to be gone more than a few days, try to have your car charged to 90% as it will consume some energy as it's parked. If you're only leaving for a day or two, then a 70 - 80% charge should be more than fine.
Since your car will be unplugged and unable to charge, you can help preserve the battery by turning off Sentry Mode if it won’t be needed as this consumes quite a bit of energy.
You will also want to turn off Stand By Mode in the Autopilot menu. Standy By Mode keeps your car's computer on so that you have instant access to features such as Summon. However, it does use additional energy.
To further preserve the car's battery, you can turn off Cabin overheat protection, which is used to keep the cabin from overheating. The car attempts to keep the cabin below 105°F.
Keep the car away from harsh weather, if it's winter then keeping it in a parking garage and away from wind will help. If it's the dead of summer, then also try to keep it under a covered area in the shade if possible.
If you’d like to check in on your car, it will need to have a good cellular connection.
Before leaving, confirm that the car has a good connection so that you can check on the battery level if needed. However, do not open up the Tesla app often, as doing so will wake up the car and keep it awake for about 15 minutes, consuming more energy. Only check on the car if you absolutely need to.
Keep in mind the amount of charge you’ll need in your car when heading back home or reaching your first charging destination. If you’re leaving your car plugged in, then you can expect the car to remain at the same charge percentage if there are no power outages. However, if the car is not plugged in, it may have a significantly less charge when you return.
As you can tell, it will be much easier and safer if you’re able to leave your car plugged in while going on vacation, especially if it’s for an extended period of time.
If you plan to store your Tesla for longer periods of time, you should find a place to keep your Tesla plugged in and follow the “if you can leave your car plugged in” tips above.

Rendering of what Tesla's license plate feature could look like
Not a Tesla App
Tesla update 2024.38 has started rolling out to several regions and vehicles. Thanks to Tesla hacker Greentheonly, we have a behind-the-scenes look at some new features coming to Teslas.
License Plate Display
According to Greentheonly, it looks like Tesla may soon let you display your actual license plate in the vehicle’s visualization on the screen. In our article, The Most Request Tesla Features, several readers suggested displaying the vehicle’s license plate in the visualization instead of a blank, white plate.
It looks like Tesla will be doing just that, at least in China. Green found references that appear to conclude that you’ll be able to display your vehicle’s plate on screen. This will likely be user input, so you could have it say anything you’d like, and it doesn’t have to be your actual license plate.
For many owners, who may find it difficult to remember their license plate, this could serve a practical purpose in addition to adding to the visualization's realism.
While Green was only able to say it’ll be available in China, we expect this is due to China’s software development team working on it and that it’ll eventually be released worldwide.
While code for this feature was found in update 2024.38, we may not be turned on in China yet. We suspect this feature may be a strong candidate for Tesla’s upcoming holiday update.
FSD Hardware Version Display
As part of the 2024.38 update, Tesla has now made it easy to determine whether your vehicle includes Hardware 3 or Hardware 4. You can now simply navigate to Controls > Software and tap Additional Vehicle Information. In addition to other hardware information about your vehicle, your Autopilot hardware version will now be listed as well.
You can see whether your vehicle has HW2.5, HW3, or AI4. This in-car display is useful, but if you don’t have access to the vehicle, you can always use our guide on how to determine the hardware version of a Tesla.
New Battery Health Test & Service Mode Improvements
Green found some additional things as well. There’s a new and improved Battery Health Test. The new test will show you how your car scores compared to similar vehicles in the Tesla fleet.
In addition, maintenance records can now be permanently stored “in the car.” It doesn’t appear that this feature is activated yet, but it’s likely in active development with some parts leaking out in the 2024.38 update.
Tesla has included various Service Mode improvements and new visualizations in this update.
Mr Li on X came across some covered-up Project Juniper vehicles recently and he managed to get various shots of the vehicle.
Juniper Images
This front image reveals what looks like two rows of lights, possibly confirming the front light bar for the Model Y refresh — similar to the one on the Cybercab.
The rear side has a lot of lights on it!
Mr Li on X
The rear side shows a ton of brake lights, but it’s not clear why. While it looks like the Model Y refresh will also feature a rear light bar similar to the Cybertruck, there isn’t strong evidence of that in this photo.
Mr Li on X
There's an obvious set of lights at the bottom, so it looks like the Model Y refresh will be similar to the new Model 3 where the bottom lights can operate as brake lights when the one-piece tail lights and trunk are up.

In the last photo, we see that the overall form factor of the refreshed Model Y will remain unchanged, and Tesla is focusing the changes on the front and rear ends of the vehicle, much like the Model 3 refresh. However, in this one shot, we can also see what appears to be red light leaking out of the rear camera cover opening, possibly due to the rear light bar.
The Model Y is not only Tesla’s best-selling vehicle but also the world’s best-selling car in 2023. This year, it’s expected to be the best-selling vehicle in the United States and again in the world, so this refresh will be huge for Tesla.
@DominicBRNKMN made another fantastic set of concepts based on these new images. Given he had the most accurate Model 3 Highland concept before the official launch, we’re pretty sure his latest work be close here as well.

We’re super excited to see the eventual reveal of Project Juniper, which is expected in the first half of 2025. However, expect to see a few more leaks before production kicks off at Giga Shanghai.
