Tesla Model 3 Charging at Ionity

Tesla Model 3 Charger Won't Start a Charging Session

You have plugged in your Model 3, the charge port light is doing something weird, and nothing is happening. This is one of the most common frustrations for EV drivers. The good news is that it is almost always fixable on the spot. The cause is usually authentication, the charge port latch, or the charger itself.

Symptoms

• Charge port LED flashes amber or red after plugging in the CCS2 connector
• Touchscreen shows an error message instead of the charging screen
• Charger display says 'Waiting for vehicle' or 'Authentication failed'
• Charge port will not open when pressing the button on the connector
• Supercharger session does not start automatically after plugging in

What to Do

1. 1

   Unplug and replug the connector firmly

   Pull the connector out completely. Wait 5 seconds. Push it back in firmly until you hear a click and the charge port LED turns green or starts pulsing. On CCS2, the lower DC pins need to seat fully.

2. 2

   Check the touchscreen for error messages

   Look at the charging screen on the touchscreen. It will tell you if there is an error, if scheduled charging is active, or if the car is waiting for something. If Scheduled Charging is delaying the session, tap 'Charge Now' to override it.

3. 3

   Authenticate with the charging network

   At non-Tesla chargers, open the network's app (Ionity, Shell Recharge, or whichever network). Start the session through the app, or tap your RFID card on the charger. At Tesla Superchargers, this step is automatic.

4. 4

   Try the manual charge port release if the port is stuck

   If the charge port will not open, try tapping your Tesla key card on the B-pillar and pressing the charge port door. You can also open it from the touchscreen under Controls. In freezing weather, pour lukewarm water around the port to melt ice. Never force it.

5. 5

   Restart the touchscreen

   Hold both scroll wheels on the steering wheel for about 10 seconds until the Tesla logo appears. This restarts the infotainment system and can clear communication errors between the car and the charger.

6. 6

   Try a different charger or stall

   If nothing works, the charger may be faulty. Move to a different stall or station. At Superchargers, the Tesla app shows stall availability in real time.

Tesla Model 3 Payment Failed at the Charging Station

You plugged in, everything looked fine, and then the charger says payment failed. Or the session will not start because authentication did not go through. Payment problems are different at Tesla Superchargers versus non-Tesla CCS2 chargers, so the fix depends on where you are.

Symptoms

• Charger display shows 'Payment failed' or 'Transaction declined' after tapping a card
• Tesla Supercharger session will not start and the Tesla app shows a billing error
• Non-Tesla CCS2 charger shows 'Authentication failed' after scanning RFID or using an app
• Contactless payment terminal on the charger does not respond to your bank card
• Charging starts but stops after a few seconds with a payment-related error on the charger screen

What to Do

1. 1

   Check if this is a Tesla Supercharger or a non-Tesla station

   At Tesla Superchargers, payment is automatic through your Tesla account. At non-Tesla CCS2 chargers, you need to authenticate separately. The fix is completely different for each.

2. 2

   For Superchargers: update your payment method in the Tesla app

   Open the Tesla app, go to Account, then Payment. Check that your card is current and not expired. Add a new card if needed. Then try the Supercharger again. The session should start automatically after plugging in.

3. 3

   For non-Tesla chargers: authenticate through the network app

   Open the charging network's app (Ionity, Shell Recharge, Virta, or whichever network runs the charger). Select the charger, start the session, then plug in. Make sure the app shows your payment method is valid.

4. 4

   Try a different payment method at the charger

   If the contactless terminal failed, try the network's app instead. If the app failed, try an RFID card. If you do not have the network's app, some chargers accept ad-hoc payments through a QR code on the charger.

5. 5

   Call your bank if repeated transactions are declined

   If your card keeps getting declined at chargers, your bank may be blocking charging transactions. Call the number on the back of your card and let them know you are making EV charging payments. They can whitelist these merchants.

6. 6

   Move to a different charger if the payment terminal is broken

   If the charger's payment terminal is physically unresponsive, try a different stall. Report the broken terminal through the network's app so they can fix it.

Tesla Model 3 Charging Slower Than Expected at Charger

You plugged in your Model 3 expecting 175 kW and the touchscreen shows 50 kW. Or your home wallbox is stuck at 3 kW instead of 11 kW. Slow charging on the Model 3 is almost never a defect. It is usually the battery temperature, a charger limitation, or a setting you can fix on the touchscreen in under a minute.

Symptoms

• DC fast charging power well below the 175 kW maximum shown on the touchscreen
• AC home charging stuck at 3-4 kW instead of the expected 11 kW
• Charging speed drops sharply after reaching 50-60% on the touchscreen
• Supercharger shows lower kW than the stall is rated for
• Touchscreen charging animation shows a slow trickle instead of rapid charging

What to Do

1. 1

   Check the battery temperature on the touchscreen

   Tap the charging icon on the touchscreen. If the battery is cold, you will see a snowflake icon or a message about reduced charging speed. To fix this, use the Tesla nav to route to a Supercharger. The car will automatically precondition the battery during the drive.

2. 2

   Check your state of charge

   If you are above 80%, the slower speed is expected. For the fastest DC charging, arrive between 10-20%. The Model 3 LFP hits peak power in the 10-50% range.

3. 3

   Move to an unpaired Supercharger stall

   Look at the stall numbers. If they are labeled in pairs (1A/1B, 2A/2B), pick a stall where the paired stall is empty. At V3 or V4 Superchargers, this is not an issue.

4. 4

   Check the AC charge current limit

   On the touchscreen, go to Controls, then Charging. Look for the charge current slider or setting. Make sure it is set to the maximum value. This only affects AC charging, not Supercharging.

5. 5

   Try a different charger or stall

   If speeds are still low, the charger may be degraded. Try a different stall at the same location. On non-Tesla CCS chargers, some stations deliver less power than advertised.

6. 6

   Check for a software update

   Go to Controls, then Software on the touchscreen. If an update is available, install it. Tesla occasionally adjusts charging curves through software updates.

Session won't start after contactless payment

You tap your card, the reader beeps, but the charger never begins delivering power. This is one of the most reported issues at Ionity stations.

Symptoms

• Contactless reader shows a green light but nothing happens
• Screen says 'Initializing' for more than 60 seconds
• Card is charged a pre-authorization hold but no energy is delivered
• Error message appears after the tap but disappears too quickly to read

How to Fix It

1. 1

   Unplug the cable and wait 10 seconds

   This resets the charger's session state. Plug the cable back in firmly until you hear the locking click.

2. 2

   Try a different payment method

   Open the Ionity app and start the session from there instead. If you have an Ionity subscription, use the app. App-initiated sessions bypass the contactless reader entirely.

3. 3

   Check your card's contactless limit

   Some banks block contactless transactions above a certain amount. Ionity may pre-authorize up to 100 EUR. If your bank flags this, the session fails silently.

4. 4

   Move to another stall at the same station

   Individual charger units can have faulty card readers while the rest of the station works fine. Try the next available stall.

5. 5

   Check for a pending hold on your bank statement

   If a hold was placed but no session started, it typically releases within 3 to 7 business days. You will not be charged for energy you did not receive.

Plug & Charge pairing fails

Your vehicle supports Plug & Charge (ISO 15118) but the Ionity station does not recognize it. The charger asks for payment instead of starting automatically.

Symptoms

• Charger prompts for app or card payment instead of starting automatically
• Screen shows 'Vehicle not recognized'
• Plug & Charge worked at this station before but stopped working
• Pairing completed in the Ionity app but the station still asks for payment

How to Fix It

1. 1

   Verify Plug & Charge is enabled in your vehicle settings

   Some vehicles (like Porsche Taycan, BMW iX, Mercedes EQS) have a toggle in the infotainment system. If it was turned off during a software update, the charger cannot identify your car.

2. 2

   Re-pair your vehicle in the Ionity app

   Go to the Ionity app, navigate to Plug & Charge settings, remove the existing pairing, and set it up again. This refreshes the digital certificate.

3. 3

   Check that your Ionity subscription is active

   Plug & Charge on Ionity requires an active subscription. If your subscription lapsed, the auto-start will fail even if the pairing is intact.

4. 4

   Try unplugging and re-plugging slowly

   The ISO 15118 handshake happens in the first few seconds. If you plug in too quickly or the connector is not fully seated, the handshake times out and the charger falls back to manual payment.

5. 5

   Start the session via the app as a fallback

   Plug & Charge issues are often caused by backend certificate mismatches. You can still charge at Ionity subscription rates by starting the session through the app while the issue is resolved.

Charger screen frozen or unresponsive

The charger display is stuck on a loading screen, shows garbled text, or does not respond to touch. The hardware may still work even if the screen does not.

Symptoms

• Screen shows a logo or loading animation that never progresses
• Touch inputs on the screen do nothing
• Screen is completely black but the charger lights are on
• Screen shows an error code that does not clear

How to Fix It

1. 1

   Try plugging in and starting via the app

   The screen and the charging hardware are separate systems. Many Ionity chargers will still deliver power even with a frozen display if you initiate the session through the Ionity app.

2. 2

   Unplug completely and wait 30 seconds

   Sometimes unplugging triggers a soft reset of the charger unit. Wait, then try again.

3. 3

   Try a different stall

   Ionity stations typically have multiple charger units. A frozen screen on one unit does not affect the others.

4. 4

   Report the charger in the Ionity app

   Open the Ionity app, find the station, and report the specific charger as out of order. This helps Ionity dispatch maintenance faster.

App shows station available but charger is faulted

The Ionity app shows green (available) status for a station, but when you arrive, the chargers display errors or are physically out of service.

Symptoms

• App shows 'Available' but charger displays 'Out of Order'
• All stalls at the station are faulted despite the app showing availability
• Charger has a maintenance sticker or barrier but the app has not been updated
• You drove to a station specifically because the app said it was free

How to Fix It

1. 1

   Refresh the station status in the app

   Pull down to refresh the station view. Status updates can lag by several minutes, especially after a charger was recently reported or rebooted.

2. 2

   Check individual charger status, not just the station

   Tap into the station details in the Ionity app. Even if some stalls show faulted, others at the same station may still work.

3. 3

   Try plugging in anyway

   Occasionally a charger shows a stale error on its screen from a previous session but works fine for the next user. Plug in and attempt to start via the app.

4. 4

   Plan a backup station

   Before driving to an Ionity station, check if there is an alternative station within 10 to 15 minutes. Ionity stations along highways sometimes have another Ionity or competitor station at the next exit.

5. 5

   Report the discrepancy

   Use the 'Report a problem' option in the Ionity app. Accurate reports help Ionity fix status sync issues and prioritize maintenance.

Unexpectedly high ad-hoc price

You charged without an Ionity subscription subscription and the per-kWh price is significantly higher than you expected. Ionity's ad-hoc rate is one of the most expensive in Europe.

Symptoms

• Invoice shows 0.75 EUR/kWh or higher
• Total cost for a short session is much higher than expected
• Price displayed on the charger screen was not noticed before starting
• You assumed the price would be similar to home charging or other networks

How to Fix It

1. 1

   Check if Ionity subscription would save you money

   Ionity offers subscription plans that reduce the per-kWh price significantly. Check the Ionity app for current plans and rates. If you charge at Ionity more than once or twice a month, a subscription usually pays for itself.

2. 2

   Check your vehicle manufacturer's charging plan

   Many EV manufacturers (Hyundai, Kia, BMW, Mercedes, Volkswagen Group, Ford) offer bundled Ionity pricing through their own apps. You may already have access to a discounted rate through your car brand.

3. 3

   Look at the charger screen before starting next time

   Ionity displays the per-kWh price on the charger screen before the session starts. The ad-hoc price is always shown.

4. 4

   Consider roaming providers for occasional use

   If you do not want a subscription, some roaming apps (like Shell Recharge, Chargemap, or Maingau) offer lower Ionity rates than the ad-hoc price.

Charging speed much lower than 350 kW

The station advertises 350 kW but your vehicle is charging at a fraction of that speed. This can be normal or it can indicate a problem.

Symptoms

• Dashboard shows 50 to 100 kW at a 350 kW charger
• Charging started fast but dropped sharply after a few minutes
• Other vehicles at the same station seem to charge faster
• Speed is lower than what you normally get at Ionity

How to Fix It

1. 1

   Check your battery level

   Charging speed drops significantly above 60 to 80% state of charge on most vehicles. This is normal battery behavior, not an Ionity issue. For the fastest stop, charge from 10 to 80% and move on.

2. 2

   Check the battery temperature

   Cold batteries charge slowly. If your vehicle supports battery preconditioning, set the Ionity station as your navigation destination. The car will warm the battery on the way there.

3. 3

   Verify your vehicle's max DC charging speed

   Not all EVs can accept 350 kW. Many popular models top out at 100 to 150 kW. The charger delivers only what the vehicle requests.

4. 4

   Try a different stall

   Individual charger units can occasionally have hardware limitations or faults that reduce output. Moving to another stall at the same station can sometimes restore full speed.

5. 5

   Check for power sharing

   Some Ionity stations share power between adjacent stalls. If the neighboring stall is also in use, both vehicles may receive reduced power. Try a stall that is not next to another active session.
