Tesla Model S Charging at Allego

Tesla Model S Charger Will Not Start a Session

You plugged in your Model S and nothing is happening. No green light on the charge port, no animation on the 17-inch touchscreen, just silence. Whether you are at a Supercharger, a third-party CCS2 station, or a home wallbox, there are a handful of common reasons the session will not begin.

Symptoms

• Charge port LED stays white or flashes red after plugging in the connector
• 17-inch touchscreen shows no charging animation or displays an error message
• Supercharger stall makes a click but does not begin delivering power
• CCS2 connector at a third-party station locks in but charging never starts
• Tesla app shows 'Not Charging' even though the cable is connected

What to Do

1. 1

   Check the charge port LED color

   Walk to the left rear of the car and look at the charge port light. White means ready but not connected. Blue means communicating. Green means charging. Red or amber means there is a fault. If it is white with the cable plugged in, remove and reseat the connector firmly.

2. 2

   Unplug and replug the connector

   Remove the connector completely, wait five seconds, then reinsert it until you hear the latch click. On CCS2 connectors, make sure both the top (AC pins) and bottom (DC pins) sections are seated properly.

3. 3

   Check for scheduled charging on the touchscreen

   On the 17-inch touchscreen, go to Controls, then Charging. If scheduled charging is active, you will see the planned start time. Tap to disable it or select 'Charge Now' to override the schedule.

4. 4

   Authorize the session at non-Tesla chargers

   At third-party CCS2 stations, check whether the charger requires you to start the session through an app, RFID card, or contactless payment. Plug & Charge works at supported stations, but many still require manual authorization.

5. 5

   Try a different stall or charger

   If you are at a Supercharger, move to a different stall. If you are at a third-party station, try the other connector. A faulted charger looks identical to a working one from the outside.

6. 6

   Restart the touchscreen

   Hold both scroll wheels on the steering wheel for about 10 seconds until the 17-inch touchscreen goes black and reboots. This resets the charging controller and fixes some communication glitches. The car stays on during the reboot.

Tesla Model S Payment Failed at Charging Station

You are plugged in and the charger is waiting for payment, or the Supercharger session will not start because of a billing issue. Payment problems are one of the most common reasons drivers get stuck at chargers, and the Model S has multiple ways to pay depending on where you are charging.

Symptoms

• Supercharger session will not start and the Tesla app shows a payment error
• Third-party CCS2 charger displays 'Authorization failed' after tapping your card
• RFID card is not recognized by the charger's reader
• Plug & Charge does not activate at a supported station
• Contactless bank card is rejected by the charger's payment terminal

What to Do

1. 1

   Check your Tesla account payment method

   Open the Tesla app on your phone. Go to Account, then Payment. Verify your credit card is current and has not expired. If the card was replaced, update the details. Supercharger sessions will not start without a valid payment method on file.

2. 2

   Try a different payment method at the charger

   If your RFID card failed, try contactless with your bank card or phone. If contactless failed, try the charger operator's app. Having at least two payment methods gives you a backup when one does not work.

3. 3

   Scan the charger QR code for browser payment

   Most public chargers have a QR code on the unit. Scanning it with your phone opens the operator's payment page in your browser. You can usually pay with a credit card directly without downloading their app.

4. 4

   Check your banking app for blocked transactions

   Open your banking app and look for flagged or declined transactions. Some banks require you to approve the charge manually. Approve it and retry the payment at the charger.

5. 5

   Try Plug & Charge by replugging

   If the charger supports Plug & Charge, unplug the CCS2 connector from your Model S, wait a few seconds, and replug. Payment should authorize automatically through the cable. This only works if your Tesla account has Plug & Charge enabled and the charger supports ISO 15118.

6. 6

   Move to a Supercharger or a different station

   If you cannot resolve the payment issue, find a Tesla Supercharger using the nav on the 17-inch touchscreen. Supercharger billing is handled entirely through your Tesla account, bypassing third-party payment systems.

Tesla Model S Charging Slower Than Expected at Charger

You pulled into a Supercharger expecting 250 kW and the 17-inch touchscreen shows 80 kW. Or your home wallbox is crawling at 3 kW instead of 11 kW. The Model S has one of the fastest charging curves on the road, but reaching peak speed depends on battery temperature, state of charge, and a few settings you can check in under a minute.

Symptoms

• DC fast charging power well below 250 kW on the touchscreen despite a rated charger
• AC home charging stuck at 3-4 kW instead of the expected 11 kW on 3-phase
• Charging speed drops sharply after 40-50% on the touchscreen during DC fast charging
• Supercharger shows significantly lower kW than neighboring stalls
• Non-Tesla CCS2 charger delivers far less power than its rated maximum

What to Do

1. 1

   Check if the battery was preconditioned

   On the 17-inch touchscreen, tap the charging icon. If you see a snowflake icon or a message about conditioning, the battery was not warm enough when you arrived. Next time, navigate to the charger using Tesla nav at least 20-30 minutes before arrival so preconditioning kicks in automatically.

2. 2

   Check your current state of charge

   If you are above 50%, the slower speed is expected on the 95 kWh NCA pack. Peak power happens roughly between 5-30%. For the fastest charging stops on a road trip, arrive between 10-20%.

3. 3

   Move to an unpaired Supercharger stall

   Look at the stall numbers. If they are labeled in A/B pairs (3A/3B, 4A/4B), pick a stall where the paired stall is empty. At V3 or V4 Superchargers with the Magic Dock or the new V4 cable, this is not a concern.

4. 4

   Check the AC charge current limit on the touchscreen

   Go to Controls, then Charging on the touchscreen. Look for the charge current setting. Make sure it is set to the maximum amperage. This only affects AC charging at home or destination chargers, not Supercharging.

5. 5

   Try a different charger or stall

   If speeds remain low, the charger hardware may be degraded. Try another stall at the same location. On non-Tesla CCS2 stations, check the charger display for error codes or reduced power notices.

6. 6

   Check for a Tesla software update

   Go to Controls, then Software on the touchscreen. If an update is pending, install it. Tesla has adjusted charging curves through over-the-air updates in the past, sometimes improving peak speeds.

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.
