The Ultimate "Plugged-In Patch" Guide: Can I Update Tesla While Charging?
Let’s be honest, we live in the age of instant gratification. You get that notification on your 17-inch touchscreen that a fresh new software update is available, promising a fart-on-demand feature, or maybe just some legit safety improvements (booooring!). Your car is already charging in the garage—maybe you scheduled it to be done by 7 AM. The big question hits you: Can I just smash that 'Install Now' button without unplugging?
Spoiler alert: The answer is a solid, "Heck yeah, you can leave it plugged in, but it’s gonna take a little breaky-time." It's like trying to talk to your teenager while they’re on their phone—they're physically present, but the connection is paused.

| Can I Update Tesla While Charging |
Step 1: 🧐 Pre-Game Check - Don't Be a Rookie
Before you hit that update button like it owes you money, you gotta make sure your ride is ready to rumble. This isn't some quick phone app update; this is brain surgery for your car.
1.1 The Wi-Fi Vibe Check
Let’s get this straight: you need solid Wi-Fi. We're talking fiber-optic, full-bars, not that sketchy connection you get from your neighbor's unsecured network three houses down. Tesla updates are chunky, dude. Downloading 500+ megabytes over a cellular connection is like trying to fill a swimming pool with a garden hose—it’s gonna take forever and probably cost you an arm and a leg in data overages.
Pro Tip: If you see a yellow download icon, your car is basically throwing shade at your Wi-Fi setup. Get it connected to a strong network, or that update is gonna crawl slower than a sloth on a Sunday.
Tip: Focus on one point at a time.
1.2 Battery Level: Keep it Juiced, Bro
Even though you are physically plugged into the wall, a good rule of thumb is to have a decent charge—we're talking at least 20%, maybe more to be super safe. Why? Because the update is a heavy lift for the car's computer systems, and you don't want the battery to get nervous. When the car's brain is getting rebooted and re-flashed, it needs all the power stability it can get. Running out of juice mid-update is the digital equivalent of tripping the wire on the atomic bomb, so don't be that guy.
Step 2: 🔌 The Plugged-In Paradox - What Actually Happens?
So, you’re plugged in, the little charge port light is blinking green (or solid, depending on the current charge phase), and you’ve got the "Update Available" notification staring you down. Time to press the virtual big red button.
2.1 The Great Charging Pause
Here is the crucial piece of info: Your Tesla will automatically halt the charging process when the installation phase of the software update begins. It’s non-negotiable. Think of it like this: the car’s main computer is getting a total brain transplant. It needs to dedicate all its energy and focus (and some of its subsystems are going offline temporarily) to the operation. It simply can't multitask a massive software installation and manage the complex dance of pulling power from the grid at the same time.
The car is basically yelling, "Hold up, I'm busy becoming a better version of myself! Charging is now on a time-out!"
QuickTip: The more attention, the more retention.
2.2 A Digital Dirt Nap
During the install phase, your car goes into a state that is more "deep sleep" than "power nap." The screen will go dark, you might hear some weird electronic whirring or clicking noises (don’t panic, it’s just the digital ghosts working), and for a good 20 to 45 minutes (sometimes more for those monster releases), your car is a fancy, expensive paperweight. You cannot drive it. You cannot open the charge port. You can't even play the whoopee cushion sound. Don't even try to open a door or get in, unless you enjoy the sound of internal panic systems momentarily freaking out.
Step 3: ✅ Post-Update Resurrection - Charging's Back, Baby!
You’ve survived the digital overhaul! The screen lights up, the car does a little electric salsa dance on the display, and you see the new release notes. So what about that charging cable still chilling in the port?

3.1 Automatic Resume
This is the beautiful part. Once the software installation is 100% complete and the car has fully booted back up (usually within a minute or two of the screen coming back to life), it will automatically resume charging right where it left off.
No need to unplug. No need to replug. No weird, archaic ritual required.
If you were charging to 80%, it will get back to that 80%. If you were Supercharging (though most Supercharger locations don't love you updating there, it'll still pause), it will start pulling power again. The car’s brain is back in the game, it realizes it's plugged in, and it gets back to its job: getting you to the next donut shop.
QuickTip: Use the post as a quick reference later.
3.2 Check the Vitals
Go to your touchscreen, hit the 'Controls' icon, and tap on 'Software'. Just make sure the version number is the new one. Also, peek at the charging screen to ensure the current flow (kW) is back on track. If the charge port light is blinking green again, you’re golden, ponyboy. This whole process is surprisingly slick and stress-free, provided you follow Step 1 and have great Wi-Fi.
FAQ Questions and Answers
How long does a typical Tesla software update installation take?
The installation phase usually takes about 20 to 45 minutes, though some major, system-wide updates can take longer, occasionally pushing towards an hour. The download time is separate and depends entirely on your Wi-Fi speed.
Can I schedule the update to happen overnight while it is charging?
QuickTip: Pause after each section to reflect.
Absolutely, and you totally should! You can use the in-car display or the Tesla mobile app to schedule the installation for a late-night or early-morning hour (like 2:00 AM). The car will pause charging, update, and then automatically resume charging, making it a truly set-it-and-forget-it deal.
What happens if the power goes out during the update?
If the power goes out during the download phase, the car will simply pause the download and resume it when power and Wi-Fi are restored. If power cuts out during the critical installation phase, the car's internal high-voltage battery is designed to maintain enough power for the process to complete or at least get to a safe stopping point, preventing it from being bricked. It’s a robust system, but still, maybe avoid updating during a gnarly thunderstorm!
Does the update use power from the main high-voltage battery?
Yes, during the installation phase, the vehicle runs off its main high-voltage battery to ensure a stable power supply for all the electronic control units, which is why you need a decent charge level before starting.
Do I need to unlock the charge port before starting the update?
Nope. Leave it locked and plugged in. The car is smart enough to manage the connector lock on its own. It’s all part of the automatic process: pause charge, run update, resume charge, no fuss, no muss.
