Tesla Model S Charging at Ionity

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.

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.
