Why Your Charging Speed May Differ

The BMW i4 supports up to 207 kW DC charging. Helen chargers deliver up to 200 kW. The network's maximum power is lower than what the car can accept, so your effective speed tops out at 200 kW.

  • 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 Helen 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 Helen Issues

Charging section buried in the Helen app

The Helen app handles electricity contracts, energy consumption, and EV charging in one place. Finding the charging features can take a few taps if you are used to dedicated charging apps.

Symptoms

  • You opened the Helen app but cannot find how to start a charging session
  • The app shows your electricity bill but no charging options
  • You found a station list but cannot figure out how to initiate charging
  • The charging feature seems to disappear after app updates

How to Fix It

  1. 1

    Look for the EV charging or e-mobility section

    In the Helen app, EV charging is usually under a dedicated menu item like 'Charging' or 'E-mobility.' It is not on the main dashboard with your electricity contract. Tap the menu icon and scroll through the options.

  2. 2

    Make sure EV charging is activated on your Helen account

    If you are a Helen electricity customer, EV charging may need to be activated separately. Check your account settings or the Helen website. You may need to accept additional terms for the charging service.

  3. 3

    Update the app to the latest version

    Helen occasionally reorganizes the app layout. If the charging section has moved after an update, check the main menu, bottom navigation, or any new tabs that appeared. The latest version will have the current layout.

  4. 4

    Try the Helen Charging web portal as a backup

    If the app is giving you trouble, Helen also offers a web-based portal for starting sessions and viewing history. Search for 'Helen lataus' in your browser.

RFID card registration through your Helen energy account

To use an RFID card at Helen chargers, you need to register it through your Helen energy account. This is different from networks where you simply order a card and it works.

Symptoms

  • You received a Helen RFID card but it does not start the charger
  • Your third-party RFID card is not accepted at Helen stations
  • The charger shows 'Card not recognized' when you tap
  • You are not sure how to link your RFID card to your Helen account

How to Fix It

  1. 1

    Register your RFID card in the Helen app or on helen.fi

    Log in to your Helen account (app or website) and navigate to the charging or RFID section. Enter the card number printed on your RFID card. The registration may take a few minutes to activate.

  2. 2

    Wait 10 to 15 minutes after registration

    The card activation is not always instant. After registering, wait at least 10 minutes before trying the card at a charger. If it still does not work after 30 minutes, contact Helen support.

  3. 3

    Check if your RFID card is from a compatible roaming network

    Helen accepts some third-party RFID cards through roaming agreements, but not all. Cards from Virta-connected networks are more likely to work. If your card is from a network without a roaming agreement with Helen, it will be rejected.

  4. 4

    Use the Helen app to start the session as a workaround

    While you sort out the RFID issue, the Helen app can start a session directly. Select the charger on the map, tap start, and the session begins without needing a physical card.

Plugging into an AC charger when you expected DC fast charging

Helen operates both AC chargers (11 to 22 kW) and DC fast chargers (up to 200 kW) in the Helsinki area. Some locations have both types side by side, and it is easy to plug into the wrong one.

Symptoms

  • Charging speed is only 11 kW or 22 kW at a station you expected to be fast
  • The connector is Type 2 instead of CCS2
  • Your vehicle's dashboard shows AC charging, not DC
  • The charger unit looks smaller and simpler than a typical fast charger

How to Fix It

  1. 1

    Check the charger type before plugging in

    DC fast chargers are larger units with thick CCS2 cables. AC chargers are smaller, often wall-mounted or on a slim post, with a Type 2 connector. If the connector is Type 2 only, it is an AC charger.

  2. 2

    Use the Helen app to identify charger types at each location

    The app shows whether a station offers AC, DC, or both. Filter for DC fast chargers if you need a quick charge. Station listings should indicate the maximum power output.

  3. 3

    If you need speed, unplug and move to the DC unit

    If you accidentally plugged into an AC charger and need faster charging, stop the session, unplug, and move your vehicle to the DC fast charger at the same location (if available).

  4. 4

    AC charging is fine if you have time

    If you are parked for several hours (shopping, at work, overnight), an AC charger at 11 to 22 kW will add meaningful range. AC charging is also gentler on your battery than frequent DC fast charging.

Parking time limits at urban charging locations

Some Helen chargers in Helsinki are installed in areas with parking time restrictions. You may get a parking fine if you exceed the posted limit, even while charging.

Symptoms

  • You see a parking time limit sign near the charger (e.g. 2 or 4 hours)
  • You received a parking fine despite being plugged in and charging
  • Your charging session takes longer than the posted parking limit
  • You are not sure if the parking limit applies while charging

How to Fix It

  1. 1

    Read the parking signs before plugging in

    Check the parking signs near the charging spot. In Helsinki, many on-street and parking garage spots have time limits (often 2 or 4 hours). These limits typically apply regardless of whether you are charging.

  2. 2

    Set a timer on your phone

    If there is a time limit, set a phone alarm so you can move your vehicle before the limit expires. Even if charging is not complete, a parking fine is not worth the extra kWh.

  3. 3

    Use a parking disc if required

    In Finland, many time-limited parking areas require a parking disc (pysäköintikiekko) displayed on your dashboard. Set the arrival time and place it visibly.

  4. 4

    Choose locations without time restrictions for longer sessions

    If your vehicle charges slowly on AC and you need several hours, use the Helen app to find chargers in locations without strict parking time limits, such as certain parking garages or less restricted areas.

Limited coverage outside Helsinki metropolitan area

Helen's charging network is concentrated in Helsinki, Espoo, and Vantaa. If you are traveling outside the capital region, Helen chargers become scarce or unavailable.

Symptoms

  • The Helen app shows no stations along your route outside Helsinki
  • You assumed Helen would have chargers at your destination but there are none
  • The nearest Helen charger is 50 km or more away
  • You planned a road trip relying on Helen and now need alternatives

How to Fix It

  1. 1

    Check coverage before you travel

    Open the Helen app or website and zoom out on the map. Helen's stations are clustered in the Helsinki metropolitan area. If your destination is outside this zone, you will need another network.

  2. 2

    Install backup charging apps for other networks

    For travel outside Helsinki, install apps for networks with broader Finnish coverage like K-Lataus, ABC-lataus, Virta, or Recharge. Having multiple apps ready means you always have options.

  3. 3

    Use a roaming RFID card for multi-network access

    A roaming RFID card from Virta or PlugSurfing lets you access chargers from multiple networks without installing each network's app. Roaming rates may be slightly higher, but the convenience is worth it for occasional use.

  4. 4

    Plan charging stops using a multi-network route planner

    Apps like A Better Routeplanner (ABRP) show chargers from all networks. Enter your vehicle model and destination, and the app will suggest optimal charging stops regardless of which network operates them.

Helen App Tips

  • The Helen app combines energy services and EV charging in one place. Look for the dedicated charging or e-mobility section, not the electricity dashboard.
  • Use the app map to check whether a station is AC or DC before driving there. AC and DC chargers look different on the map listing, with power output shown for each.
  • The app shows real-time availability for most Helen chargers. A quick check before you leave saves a wasted trip to a fully occupied station.
  • If you are a Helen electricity customer, your charging costs may appear on the same invoice as your home electricity. Check your billing settings in the app.

Payment Tips

  • Register your RFID card through your Helen account before visiting a station. Unregistered cards will not be recognized by the charger.
  • The Helen app is the most reliable payment method at Helen stations. If your RFID card is not working, the app can start a session directly.
  • Third-party RFID cards work at some Helen stations through roaming agreements, but coverage is not guaranteed. Check with your card provider for Helen compatibility.
  • Helen's pricing is per kWh. The app shows the current rate before you start a session. AC and DC charging may have different per-kWh prices.
