Tesla Model 3 Charging at Allego

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.

Allego app not starting a session

You open the Allego app, select the charger, tap 'Start,' and nothing happens. The app may spin, show an error, or claim the charger is offline even though the screen in front of you says otherwise.

Symptoms

• Allego app shows a loading spinner that never finishes
• 'Charger unavailable' in the app but the physical charger looks operational
• App crashes when tapping 'Start Charging'
• Session appears to start in the app but the charger does not begin delivering power

How to Fix It

1. 1

   Make sure you selected the correct charger and connector

   Allego stations often have multiple charging points. Each one has its own ID, usually printed on a sticker near the connector. Match this ID to the one shown in the Allego app. Selecting the wrong point is the most common reason a session will not start.

2. 2

   Plug in the cable before starting the session in the app

   Most Allego chargers require the cable to be connected to your car first. The charger needs to detect a vehicle before it will accept a start command from the app.

3. 3

   Close and reopen the Allego app

   Force-close the app completely (swipe it away from your recent apps), wait a few seconds, and reopen it. Try starting the session again.

4. 4

   Scan the QR code on the charger instead

   Most Allego chargers have a QR code that opens a web-based payment page. This works independently of the Allego app and lets you pay with a credit card without needing an account.

5. 5

   Use an RFID card from a roaming provider

   If you have an RFID card from a provider like Shell Recharge, Plugsurfing, or Chargemap, hold it against the reader on the charger. This bypasses the Allego app entirely.

Charger not appearing in the Allego app

You are standing in front of a physical Allego charger, but it does not show up on the Allego app map. The charger is clearly operational and other drivers are using it.

Symptoms

• Charger location is missing from the the Allego app map entirely
• App shows the location but with zero available connectors
• Charger appears under a different brand name in other apps but not in the Allego app
• Newly installed charger not yet listed

How to Fix It

1. 1

   Check if the charger is operated under a different brand

   Allego operates under various local labels in different countries. The charger might be listed under the local brand name rather than 'Allego' in some apps. Look for a sticker or sign on the charger that shows the operator name and EVSE ID.

2. 2

   Search by charger ID instead of location

   In the Allego app, try the search function and enter the charger's EVSE ID (printed on the unit, usually starting with a country code like DE*, NL*, or FR*). This can find chargers that are not correctly placed on the map.

3. 3

   Use the QR code on the charger

   Scan the QR code on the charger with your phone camera. This will open a direct link to start a session, even if the charger is missing from the app map.

4. 4

   Try a different charging app

   Allego chargers are accessible through many roaming providers. Open an app like Chargemap, Shell Recharge, or Plugsurfing and search for the same location. You may be able to start the session there.

Third-party RFID card not accepted

You hold your RFID card from another provider against the reader and the charger beeps but rejects it, or nothing happens at all.

Symptoms

• Charger beeps once but displays 'Card not recognized'
• No reaction when holding the RFID card to the reader
• Card works at other networks but not at this Allego charger
• 'Authorization failed' message on the charger screen

How to Fix It

1. 1

   Check if your roaming provider covers Allego

   Not all RFID providers have roaming agreements with Allego. Check your provider's app or website to confirm Allego is listed in their coverage. Some providers cover only certain Allego locations.

2. 2

   Hold the card flat and steady for 3 seconds

   Do not wave or tap the card. Place it flat against the reader and hold it still. Allego readers can be slower to respond than some other networks.

3. 3

   Try a different position on the reader

   The RFID antenna inside the reader has a specific sweet spot. Move your card slowly across the reader surface until you get a response. On some Allego chargers, the reader is on the right side panel rather than the front.

4. 4

   Check your RFID card is activated

   Some providers require you to activate your RFID card in their app before first use. Open your provider's app and look for card activation or card management settings.

5. 5

   Fall back to QR code or Allego app

   If your RFID card will not work, scan the QR code on the charger for direct credit card payment, or download the Allego app and register to start the session digitally.

Long delay before charging actually starts

You have authenticated and the charger says it is starting, but 30 seconds, sometimes over a minute, passes before any power flows to your car.

Symptoms

• Charger screen says 'Starting' or 'Initializing' for over 30 seconds
• Car shows 'Waiting for charger' or 'Preparing'
• Power reading stays at 0 kW for a full minute after authentication
• You wonder if you should unplug and try again

How to Fix It

1. 1

   Wait at least 90 seconds before taking action

   Allego high-power chargers perform a communication handshake with your car before delivering power. This includes safety checks, voltage negotiation, and isolation testing. A 30-60 second delay is normal, especially on 350 kW units.

2. 2

   Do not unplug during the initialization phase

   Unplugging and re-plugging resets the entire handshake process. If the charger screen shows any progress (status messages, icons changing), let it complete.

3. 3

   Check if your car's charge port is locked

   The connector should be locked into your car's charge port during initialization. If you can wiggle the connector freely, it may not be fully inserted. Push it in firmly and listen for the lock click.

4. 4

   If nothing happens after 2 minutes, restart the session

   Unplug the connector, wait 10 seconds, plug it back in, and authenticate again. If the delay repeats, try a different connector or charger at the same station.

Charging power much lower than advertised

The charger is rated for 350 kW, but your car is only pulling 50 kW or less. The session is working, just far slower than expected.

Symptoms

• Car or charger display shows 40-80 kW on a 350 kW charger
• Estimated charge time is much longer than expected
• Power started high but dropped dramatically within minutes
• Other cars at the same station seem to charge faster

How to Fix It

1. 1

   Check your battery level

   DC charging slows significantly above 60-70% state of charge on most cars. If your battery is already at 65% or higher, the reduced speed is your car protecting its battery, not a charger problem.

2. 2

   Check your car's maximum DC charging rate

   A 350 kW charger can deliver up to 350 kW, but your car decides how much to accept. Many EVs top out at 100-150 kW. Check your car's specifications for its maximum DC charging speed.

3. 3

   Consider battery temperature

   Cold batteries charge slowly. If you have been parked for hours in cold weather without preconditioning, your car may limit charging to 30-60 kW until the battery warms up. Some cars let you precondition the battery by setting the charger as your navigation destination.

4. 4

   Check if the station is power-sharing

   Some Allego stations share power between multiple chargers. If three cars are charging simultaneously, each one may get less than the maximum. This is normal at shared-power sites.

5. 5

   Try a different connector at the same station

   Occasionally one connector delivers less power due to a hardware limitation. If you are getting unusually low power even at a low battery level, unplug and try the next unit.
