What to do with your Tesla when going on vacation or storing it for longer periods of time

We’ve covered how much to charge your Tesla for everyday use, but when going on vacation or planning to store an electric car we have just a little extra planning to do.

Always keep your Tesla plugged in when going on vacation

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.

Tesla Vehicles Spotted With LiDAR: What Do They Use It For?

Not a Tesla App

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

Not a Tesla App

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
