Hyundai IONIQ 5 Charging at Ionity

Hyundai IONIQ 5 Charger Will Not Start a Charging Session

You have plugged the cable into your IONIQ 5's charge port on the right rear fender, but nothing is happening. No power flowing, no charging animation on the cluster. This is frustrating, but it is rarely the car. Most failed charging starts come from the charger, the app, or a setting on the vehicle. Here is how to work through it.

Symptoms

• Charge port light does not turn on or blinks red after plugging in
• Charger screen shows an error or returns to the start screen immediately
• Charging app shows session failed or authentication error
• Cable is plugged in but the IONIQ 5 does not recognize the connection
• Charge port door will not open, especially in cold weather

What to Do

1. 1

   Open the charge port door

   Press the button on the charge port door on the right rear fender. If it will not open in cold weather, try pressing and holding the unlock button on your key fob, or gently warm the edges with your hands or lukewarm water. Do not force it open or use sharp tools.

2. 2

   Check for scheduled charging

   On the center touchscreen, go to EV settings and check if a charging schedule is active. You can also check in the Bluelink app under the charging section. Disable the schedule temporarily to charge immediately.

3. 3

   Unplug and reconnect the cable firmly

   Remove the cable completely, wait 10 seconds, and plug it back in. Push the CCS2 connector in until it clicks into the charge port. Make sure both the upper (AC) and lower (DC) sections are fully seated.

4. 4

   Re-authenticate at the charger

   Tap your RFID card again, restart the charging app, or try a different payment method. If the charger supports Plug and Charge and your IONIQ 5 has it enabled, try unplugging and replugging to re-trigger automatic authentication.

5. 5

   Try a different charger or stall

   If the session still will not start, the charger may be faulty. Move to a different stall at the same station. If all stalls fail, try a different charging station entirely.

6. 6

   Restart the car if needed

   In rare cases, the IONIQ 5's charging system needs a reset. Unplug the cable, sit in the car, press the start button to turn the car on, wait 30 seconds, turn it off, and try plugging in again.

Hyundai IONIQ 5 Charger Payment or Authentication Failed

You are at the charger, cable in hand, and the screen says payment failed or authentication error. Your IONIQ 5 is ready to charge, but the charger will not let you start. This is almost always a charger-side or app-side issue, not a car problem. Here is how to get charging.

Symptoms

• Charger screen shows payment declined or authentication error
• RFID card is not recognized when tapped on the reader
• Charging app shows session failed to start or payment error
• Contactless bank card is declined at the charger terminal
• Plug and Charge does not auto-authenticate after plugging in

What to Do

1. 1

   Check your charging app account

   Open your charging app and verify that your payment method is valid, your balance is sufficient (for prepaid accounts), and there is no stuck session from a previous charge. Update your payment method if the card on file has expired.

2. 2

   Try a different authentication method

   If your RFID card failed, try the app's QR code or start-via-app feature. If the app failed, try tapping your RFID card. If you have a contactless bank card, try that. Having at least two methods available saves time.

3. 3

   Check if Plug and Charge is enabled

   On the center touchscreen, go to EV settings and look for the Plug and Charge option. Make sure it is turned on. Then check if the charging network supports Plug and Charge. If both are set up, unplug the CCS2 cable and plug it back in to re-trigger authentication.

4. 4

   Restart the charger if possible

   Some chargers have a reset option on the screen or a physical button. If the charger seems stuck from a previous session, restarting it can clear the error. Check the charger screen for a reset or cancel option.

5. 5

   Move to a different charger

   If authentication keeps failing on one charger, try a different stall at the same station. Charger hardware varies even within the same location, and another unit may process your payment without issues.

6. 6

   Contact the charging network's support

   Most chargers display a phone number or support contact on the screen or on a sticker. Call or message the network's support to report the issue. They can sometimes remotely start a session or clear a stuck charger from their side.

Hyundai IONIQ 5 Charging Slower Than Expected at DC or AC

Your IONIQ 5 has one of the fastest charging architectures on the market. 800V, up to 233 kW, 10-80% in roughly 18 minutes. So when the screen shows 50 kW at a fast charger, something feels wrong. In most cases, slow charging on the IONIQ 5 is not a defect. It is usually the battery temperature, the charger's actual output, or a setting worth checking.

Symptoms

• DC fast charging speed well below the 233 kW maximum
• AC home or destination charging stuck at 3-4 kW instead of 11 kW
• Charging speed drops sharply after reaching 60-70%
• Charging session starts at low power and never ramps up
• Instrument cluster shows much lower power than the charger's rated output

What to Do

1. 1

   Check the battery temperature on the cluster

   Look at the charging information on your 12.3-inch instrument cluster or center touchscreen. If the battery temperature is low, consider driving for 15-20 minutes before your next charging stop, or use the built-in navigation to trigger battery preconditioning automatically.

2. 2

   Confirm the charger supports 800V

   Check the charger's specifications on its screen or the charging network's app. If it is a 400V charger, the IONIQ 5's multi-charging system will still work, but speeds will be lower than on an 800V unit. No adapter needed.

3. 3

   Check your state of charge

   If you are above 80%, the slowdown is expected. For the fastest road trip charging, plan stops so you arrive between 10-20% and unplug at 80%.

4. 4

   Check scheduled charging and charge limits

   Open the EV settings on the center touchscreen or in the Bluelink app. Make sure scheduled charging is not active (it can delay charging start) and the charge current limit is set to maximum.

5. 5

   Verify the charger is not sharing power

   Look at the charger unit. If two cables come from the same cabinet and someone is using the other one, you may be splitting power. Move to an unoccupied charger if available.

6. 6

   Try a different charger or station

   If the speed is still low after checking everything, the charger itself may be degraded or throttled. Try another stall at the same location, or head to a different station entirely.

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.
