Does Tesla Stop Charging During Software Update? | Fix It

Charging often pauses while the car installs an update, then it resumes on its own once the install and reboot finish.

You plug in, an update starts, and the app flips from “Charging” to “Stopped.” That can feel wrong, since you didn’t touch a thing. In most cases, it’s normal: the car pauses the charge session during the install window, then picks up again when it’s done.

Below you’ll learn what’s normal, what’s not, and what to try when charging doesn’t come back.

Why Charging Pauses During An Update

A Tesla update has two phases that matter for charging: download and install. During download, the car can charge. During install, the car takes some systems offline for a controlled reboot, and charging is one of them.

Installing firmware can touch modules that talk to the charge port, onboard charger, and battery controls. While those parts restart, the car won’t keep a live power handshake open. Tesla states this behavior in its owner manuals: if the car is charging when the software update begins, charging stops and then resumes automatically once the update completes.

Tesla Charging During A Software Update: What Changes

Charging behavior depends on timing. If you start charging first and the car begins installing later, you’ll see the session pause at the moment the install begins. If you install first and plug in later, charging works after the install ends.

What You’ll See In The App And On The Screen

On the car’s display you may see an install timer, then a progress bar, then a restart. In the phone app, charging may show “Stopped” during install and return to “Charging” after the reboot.

If you use Scheduled Charging, the reboot can land outside your charge window. Then charging won’t restart until the next scheduled window. It looks like a failure, but it’s just your schedule doing its job.

How Long The Pause Can Last

Many installs finish within minutes, but installs vary by model and what’s included. A long pause does not always mean trouble. The real check is whether the update is still running.

When A Pause Should Make You Pay Attention

• The update finished and charging never restarts.
• You get repeated “Charging Stopped” alerts after the update, not just once.
• The charger shows a fault light or your breaker trips.
• A public station ends the session and won’t restart without re-auth.

How To Set Up A Smooth Update Night

You can avoid most stress with a small routine. The goal is to keep the install from landing right in the middle of the charge window you rely on.

Pick A Time That Matches Your Charging Plan

If you charge overnight to meet a morning departure, start charging earlier on update nights. That gives the car time to catch up if the install pauses the session.

If you use Scheduled Charging and your window is narrow, widen it for that night, then set it back later.

Stay Plugged In, But Don’t Start The Install At A Public Charger

At home, a pause and auto-resume is the common pattern. At some third-party stations, the session can end when the car stops drawing power, and it may not auto-restart. If a station needs a tap, app start, or per-session approval, finish the charge session first, then install later.

Know Where Tesla States This

The Model Y manual’s “Software Updates” page says charging stops when an update begins and resumes after completion. Model Y manual: “Software Updates”.

What Happens Step By Step During Updates And Charging

Use the table below to match what you see with what the car is doing. It helps you decide whether to wait, adjust a setting, or start troubleshooting.

Update Stage	What You Might Notice	What Happens To Charging
Update available	App shows a new version ready	Charging works normally
Downloading	Progress indicator, car still usable	Charging keeps going
Install scheduled	Timer counting down	Charging continues until install starts
Install begins	Car disables driving	Charging stops at the start of install
Installing	Progress bar on screen or app	Charging remains paused
Reboot	Screen resets, lights cycle	Charging stays paused
Update complete	Release notes appear	Charging auto-resumes if the session is still valid
Schedule check	Charging stays off until the next window	Charging waits for Scheduled Charging rules

If Charging Does Not Resume After The Update

When charging doesn’t come back, start with the lowest-effort checks. Most fixes are settings, session state, or equipment.

Step 1: Confirm The Update Is Finished

Open the car screen or the app and confirm the install is complete. If the car is still installing, a paused charge session fits the normal behavior. Wait until the car is fully back, then check charging again.

Step 2: Check Scheduled Charging And Charge Limit

Two settings can make a normal resume look like a failure:

• Scheduled Charging. If the current time is outside your window, charging won’t restart yet.
• Charge limit. If the limit is already reached, the car will sit idle while it’s plugged in.

Step 3: Unplug, Wait, Replug

Unplug the connector from the car, wait a few seconds, then plug it back in. Watch the charge port light and the app status. If you’re at a station that requires a fresh start, begin a new session in the station’s app or on its screen.

Step 4: Swap The Charging Source

If you can, try a different outlet, a different cable, or a different station. If the problem only happens on one charger, the car is often fine.

Step 5: Reset Home Charger Power When A Fault Latches

On home equipment, a simple power reset can clear a fault state. Tesla’s manual troubleshooting steps include turning off the circuit breaker that feeds the Wall Connector, waiting, then turning it back on before trying again. Model 3 manual: “Troubleshooting Alerts”.

Step 6: Check Whether A Recall Update Is In Play

If you want to see recall campaigns tied to your vehicle, you can check your VIN on the U.S. regulator’s recall lookup tool. NHTSA recall lookup.

Common Scenarios That Trip People Up

Scheduled Charging Blocks The Restart

If the reboot happens after your schedule window closes, the car may wait until the next start time. The fix is simple: widen the schedule window that night or turn scheduling off until you reach your target level.

A Third-Party Station Ends The Session

Some stations treat a pause as the end of the session. You may need to re-auth, re-plug, or start a new session after the update. If you can’t stay nearby, install updates at home when you can.

The App Status Looks Stale After The Reboot

After an update the car may take a bit to settle. Wake the car, refresh the app, and check the live charge rate. If charging is running, the numbers will update.

Charging Stops Repeatedly After The Update

Repeated stops often point to heat, wiring, a loose plug, or a charger fault. Treat it as an equipment check, not an update problem. The update timing can be a coincidence.

Fast Troubleshooting Map

The table below keeps the decision tree tight. Start at the symptom that matches what you see, then try the paired action.

Symptom	Likely Cause	What To Try Next
Charging paused while install is running	Normal install behavior	Wait for the update to finish
Update finished, charging still off, schedule window closed	Scheduled Charging rule	Widen window or toggle scheduling off
Update finished, station shows session ended	Public station session ended	Start a new session and replug
Charge port light red or charger fault light on	Equipment fault	Unplug, replug, then try another charger
Charging stops every few minutes	Heat or wiring issue	Lower charge current and check plug seating
Breaker trips	Circuit problem	Stop charging and get the circuit checked by a licensed electrician
No charging on multiple sources	Vehicle-side issue	Book a service appointment in the Tesla app

Why The Car Pauses Charging During Install

An install is more like a controlled restart of multiple controllers than a phone update. If the module that manages charge control is restarting, the car won’t keep a live power handshake open.

The U.S. regulator has published background material on over-the-air firmware updates and safe update practices. It’s not Tesla-specific, but it explains the general model: staged installs, checks, and validation. NHTSA: “Cybersecurity of Firmware Updates” (PDF).

Checklist For The Next Update While Plugged In

• Start charging earlier if you need a full battery by morning.
• Widen Scheduled Charging for that night, or toggle it off until you hit your target.
• Install at home when you can, not at a station that needs per-session approval.
• If charging doesn’t resume, confirm the update finished, then unplug and replug.
• If the session keeps failing, try another charger and reset home charger power.
• If the car won’t charge on any source, book service through the app.
