🤠🔌 Can You Seriously Update Your Tesla While It's Chugging Juice? A Deep Dive for the Digital Driver
What is up, Tesla fam? Let's be real, owning one of these electric steeds is like being in a super exclusive, future-forward club. You’ve got the silent power, the ludicrous speed (if you sprung for it, you baller!), and those legendary Over-The-Air (OTA) software updates that make your ride better while you sleep. It's like getting a new car for free! But a question that pops up more often than a squirrel at a picnic is this: Can you run that sweet, sweet software update while your Tesla is plugged in and getting its electrons?
It's a fantastic question, and one that gets right to the heart of EV ownership convenience. We're talking maximum efficiency, folks! Imagine: you pull up to your home charger or a blazing-fast Supercharger, plug in, and hit that "Install Now" button. Two birds, one stone, right? Well, grab your metaphorical popcorn because the answer has a few twists and turns, like a winding mountain road on Autopilot. Let's break down this electrifying process and separate the facts from the fictional flim-flam.
Step 1: The 'Download' Phase - Chillin' Like a Villain
First off, it's essential to understand that a Tesla software update is a two-act play: the Download and the Install. They're not the same thing, and they have totally different rules about charging.

| Can You Do Tesla Update While Charging |
1.1. Grabbing the Goods: Wi-Fi is Your Bestie
When Tesla sends out a new, shiny software package (maybe it’s FSD improvements, maybe it’s a new fart sound—you never know!), your car needs to download it. This is basically the car equivalent of downloading a massive video game patch.
The Key Player: For the fastest and most reliable download, your Tesla needs to be connected to Wi-Fi. Seriously, treat your Wi-Fi connection like it's the golden ticket. Using the car's cellular connection can happen for smaller, essential updates, but for the big dogs, it's Wi-Fi all the way.
Charging Status: During this download phase, your car can absolutely be plugged in and actively charging. It’s multitasking like a champ! The car just uses the internet connection (mostly Wi-Fi, remember?) to suck down the data. The charging system doesn't really care what the infotainment system is doing with its data packets. So, if you're juicing up at home, you can start that download. No sweat.
1.2. On the Road: Supercharger Downloads
Tip: Take your time with each sentence.
"Wait, I'm at a Supercharger, can I download it there?" Great question, my dude. Many Supercharger stations now have a Wi-Fi hookup. If your car connects to it, the download can start. However, Superchargers are designed for speed and getting you back on the highway, not for hanging out and downloading gigabytes of data. The focus is charging. You might see the little green download arrow pop up if you're lucky and the Wi-Fi is strong, but don't count on it. The real action starts when you hit that "Install" button.
Step 2: The 'Installation' Phase - The Big Moment of Truth
This is where the rubber meets the road, or more accurately, where the new software takes over the car's brain. This phase is a whole different kettle of fish.
2.1. The Grand Shut Down
When you hit 'Install Now' or when your scheduled update time rolls around (and your car is safely parked), your Tesla becomes a temporary brick. That sounds dramatic, but it's true! The entire vehicle shuts down its main functions to allow the new firmware to be flashed onto the various Electronic Control Units (ECUs)—basically, all the mini-computers that run everything from the motor to the blinkers.
You Cannot Drive: For obvious, safety-first reasons, you absolutely, positively cannot drive during this process. The screen will go dark, the lights will flash, and your car will look like it's having a silent, high-tech existential crisis. It's usually about 25-30 minutes of downtime, so plan accordingly. Don't start an install when you're late for a date!
2.2. The Charging Interruption: The Official Stance
Okay, so here's the money shot, the final verdict, the TL;DR for the whole charging-while-installing dilemma:
QuickTip: Scroll back if you lose track.
"If plugged in, your vehicle will stop charging until the installation is complete."
That's the word from the big T itself. When the install starts, the car takes priority. It needs all the power and control to manage the delicate software upgrade. It essentially tells the charger, “Hold up, partner. I’ll call you back.”
The key takeaway is this: You can start the install while the charger is physically plugged in, but the car will immediately cease drawing power from the charging cable for the duration of the installation.
2.3. Why the Charging Hiatus is a Good Vibe
Why does Tesla do this? It's not because they're being extra. It's a fundamental safety and integrity check.

System Integrity: An update involves rebooting core systems. If the car were trying to manage a massive influx of DC power (like from a Supercharger) or even a steady flow of AC power at the same time, it could introduce unpredictable variables. By hitting pause on the charge, the car ensures a stable, controlled environment for a successful install. You don't want a "bricked" car because of a momentary power spike!
Battery Management: The car needs its full focus on the update. Plus, if the update includes new battery or charging logic (which they often do to improve efficiency—score!), you want that new logic in place before charging resumes. It’s like installing new glasses before reading the fine print.
Step 3: Post-Install Shenanigans - Getting Back to the Juice
Once the 30-ish minute digital surgery is complete, your Tesla will wake up, do a happy little reboot dance (sometimes literally, with the headlights), and show you the updated release notes. So, what happens to the charging cable?
Tip: Don’t overthink — just keep reading.
3.1. Automatic Resume: It's All Good
If you had the charger plugged in when the install started, your car will be a pro about it. Charging will automatically resume once the update is 100% finished and the car is back online. No need to go outside in your pajamas to unplug and replug the connector (unless you want to, for a cool photo op).
Supercharger Note: If you're at a Supercharger, the charge session will resume, but a critical note: watch out for idle fees! Superchargers are a high-traffic area. While the car is updating, the charging is paused, but the clock is still running on how long you've been sitting there. If your update takes 30 minutes and you hit your charge limit, you could start racking up those notorious idle fees if you don't unplug pronto after charging is complete.
3.2. Checking the New Features
The first thing you’ll want to do is cruise over to the Controls > Software screen to check out the new software version and the release notes. Maybe you got a new feature for your glovebox menu, or maybe your regenerative braking got a little tighter. Every update is like opening a surprise box!
FAQ Questions and Answers
How to Check if a Tesla Update is Available?
You can check for an available update by navigating to Controls > Software on your touchscreen. If an update is available for download or installation, you will usually see a notification icon (a green or yellow arrow, or a clock icon) at the top of the touchscreen, which also acts as a shortcut.
Tip: Absorb, don’t just glance.
What Happens if I Start Driving During the Download Phase?
You are totally fine! You can drive your Tesla while the new software is downloading. However, if you are downloading over Wi-Fi and you drive out of range of that network (like leaving your garage), the download will pause until you reconnect to a strong Wi-Fi signal.
How Long Does a Typical Tesla Software Update Take?
The actual installation time, where your car is offline, generally takes about 25 to 30 minutes. However, major updates can sometimes take longer. Always check the on-screen estimate and make sure you have enough time before you need to drive.
Can I Reschedule a Tesla Update?
Yes, absolutely. When a software update is ready to install, a clock icon will appear on your touchscreen. Tapping this will bring up a scheduling window where you can choose to "Install Now" or "Set For This Time" to pick a time that works better for you, such as 2:00 AM.
Do I Need to Unplug My Car Before Installing the Update?
No, you do not need to unplug. It is completely safe to leave your charging cable physically connected. The car’s system is designed to stop the flow of charging power during the installation process and then automatically resume it once the software update is finished.
