Why Your Charging Speed May Differ

The BMW i4 supports up to 207 kW DC charging. Ionity chargers deliver up to 350 kW. Your car's maximum intake is the limiting factor here, capping speed at 207 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the BMW i4.
  • Cold weather reduces charging speed. The BMW i4 supports battery preconditioning, which helps.
  • If multiple cars share the same Ionity station, power may be split between stalls.

BMW i4 Charging Problems

BMW i4 Charger Won't Start? Step-by-Step Solutions

You've plugged in the CCS2 cable to your BMW i4's right rear charge port, but nothing happens. This is one of the most common frustrations at public chargers. The good news is that most causes are fixable on the spot.

Symptoms

  • CCS2 connector is plugged into the right rear port but the charger screen shows no vehicle detected
  • Charger displays an error code and refuses to start the session
  • My BMW app shows the car is plugged in but not charging
  • The charge port LED on the i4 flashes or stays amber instead of turning blue
  • Authentication via app or RFID card goes through but charging never begins

What to Do

  1. 1

    Unplug the CCS2 cable and reseat it firmly

    Pull the connector out completely. Check the pins for debris or damage. Line it up straight with the charge port on the right rear and push until you hear a clear click. The charge port LED should respond.

  2. 2

    Check the charge port LED color on the car

    Blue pulsing means the car is ready to charge. Amber or yellow means something is wrong on the car side. No light at all may mean the port isn't detecting the cable. Open the My BMW app for more detail.

  3. 3

    Disable any charging schedule in iDrive

    On the iDrive curved display, go to the charging settings and check for active schedules or departure times. Disable scheduled charging temporarily if you want to charge immediately at a public station.

  4. 4

    Try authenticating again or use a different method

    If Plug & Charge didn't start the session, open the charging network's app and start manually. If the app fails, try an RFID card. If you're using BMW Charging, check that your payment method is current in the My BMW app.

  5. 5

    Restart the charger if possible

    Some chargers have a stop/reset button on the screen. Unplug, wait 30 seconds, and try again. If the charger has two cables, try the other connector. Check the charger's screen for error messages or an out-of-service notice.

  6. 6

    Move to a different charger if the problem persists

    If nothing works after two attempts, the charger is likely faulty. Use the My BMW app or a charging map to find the next nearest station. Report the broken charger through the network's app to help other drivers.

BMW i4 Charging Payment Failed? How to Fix It Now

You're at the charger, the CCS2 cable is plugged into your BMW i4, but payment won't go through. Maybe Plug & Charge didn't kick in, the app is throwing errors, or your card was declined. Here's how to sort it out and start charging.

Symptoms

  • Plug & Charge doesn't activate when you connect the CCS2 cable
  • BMW Charging shows a payment error in the My BMW app
  • The charger screen says authentication failed or payment declined
  • Your RFID card is not recognized at this charging station
  • Contactless card payment at the charger terminal is rejected

What to Do

  1. 1

    Check if Plug & Charge is set up in the My BMW app

    Open the My BMW app, go to your charging settings, and verify that Plug & Charge is enabled and linked to an active payment method. If you see a setup prompt, complete it before trying again.

  2. 2

    Update your payment method in BMW Charging

    In the My BMW app, navigate to your BMW Charging account and check your stored payment card. Update it if it's expired or recently replaced. The change should take effect within a few minutes.

  3. 3

    Try the charging network's own app

    Identify which company operates the charger (the logo is usually on the unit). Download their app, create an account, add a payment method, and start the session through their app instead of BMW Charging.

  4. 4

    Use a different RFID card or contactless payment

    If you have another RFID card from a different network, try that. Some chargers also accept contactless debit or credit cards. Look for a payment terminal on the charger, usually near the screen.

  5. 5

    Try a different charger at the same station or a nearby station

    Sometimes a single charger's payment terminal malfunctions while others work fine. Try the next unit over. If the whole station is problematic, use iDrive navigation to find an alternative station nearby.

BMW i4 Charging Slower Than Expected? Fixes Here

Your BMW i4 eDrive40 supports up to 205 kW DC fast charging, but real-world speeds often fall short. Several factors specific to the i4's 80.7 kWh battery and 400V architecture can limit charging power. Here's how to diagnose and fix slow charging on your i4.

Symptoms

  • DC charging speed stays well below 205 kW even at a high-power charger
  • Charging curve drops sharply before reaching 60% state of charge
  • AC charging at home or destination chargers maxes out at 3.6 kW instead of 11 kW
  • iDrive curved display shows a lower charging rate than the charger's rated output
  • Estimated charging time on the iDrive screen is much longer than expected

What to Do

  1. 1

    Use iDrive navigation to route to your charging stop

    Enter the charging station as a waypoint or destination in iDrive. The i4 will automatically precondition the battery while you drive, warming it to the ideal temperature for fast charging. This alone can double your charging speed in cold weather.

  2. 2

    Arrive at the charger with a lower state of charge

    The i4 charges fastest between 10% and 50%. If possible, plan your stop so you arrive closer to 10-20%. The difference between arriving at 15% versus 50% can save significant time.

  3. 3

    Choose a charger stall that isn't sharing power

    Look at the charger setup. If two CCS2 cables come from one cabinet, pick a stall where the neighboring connector is free. Some stations label paired stalls with A/B designations.

  4. 4

    Check your AC charging setup at home

    Open the My BMW app and look at the charging details during an AC session. If you're only getting 3.6 kW, your installation likely provides single-phase power. Ask your electrician about a three-phase connection to unlock the full 11 kW.

  5. 5

    Check the charging status on the iDrive curved display

    While charging, the iDrive screen shows current power, estimated time remaining, and battery temperature. If power is low and battery temperature is also low, the car is still warming the pack. Give it a few minutes to ramp up.

  6. 6

    Unplug at 80% and drive to the next charger if needed

    Charging from 80% to 100% on DC can take as long as 10% to 80%. On road trips, it's almost always faster to charge to 80%, drive, and stop again rather than waiting for a full charge.

Common Ionity Issues

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.

Ionity App Tips

  • Download the Ionity app before your trip. You need an account to start sessions at stations where contactless payment is not available or not working.
  • Enable push notifications in the Ionity app. You will get alerts when your session ends or if charging stops unexpectedly.
  • Use the Ionity app's filter to show only stations along your route. The app integrates with Apple Maps and Google Maps for navigation.
  • Check real-time stall availability in the app before driving to a station. Tap the station pin to see which individual chargers are free, occupied, or faulted.
  • If you have an Ionity subscription, always start sessions through the app to make sure you get the subscription rate. Contactless payment defaults to the ad-hoc price.

Payment Tips

  • Ionity offers subscription plans that significantly reduce the per-kWh price compared to the ad-hoc rate. Check the Ionity app for current plans and pricing. Worth it if you use Ionity twice a month or more.
  • Contactless payment pre-authorizes up to 100 EUR on your card. The actual charge appears later and the hold is released within a few days.
  • Check if your car brand offers an Ionity deal. Hyundai, Kia, BMW, Mercedes, VW Group brands, and Ford all have discounted Ionity access through their own charging apps.
  • Ad-hoc (pay-as-you-go) rates at Ionity are among the highest in Europe. If you do not want a subscription, roaming through Shell Recharge or Chargemap is usually cheaper than paying ad-hoc.
  • Ionity invoices are available in the app under your account. You can download PDF receipts for expense reports.
