Why Your Charging Speed May Differ

The BMW i5 supports up to 205 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 i5.
  • Cold weather reduces charging speed. The BMW i5 supports battery preconditioning, which helps.
  • If multiple cars share the same Helen station, power may be split between stalls.

BMW i5 Charging Problems

BMW i5 eDrive40 Charger Won't Start: Fix Guide Now

You have connected your BMW i5 to a charger, but the session will not start. The charger sits idle, iDrive shows nothing, or you get an error message. This is one of the most reported problems at public chargers, and the fix is usually simple.

Symptoms

  • The charger screen stays on 'connect vehicle' after plugging in the CCS2 cable
  • iDrive does not show any charging activity
  • The charge port LED on the i5 does not illuminate
  • An error code appears on the charger display
  • The connector does not lock into the charge port

What to Do

  1. 1

    Make sure the i5 is unlocked

    The charge port only opens and accepts a connector when the car is unlocked. Use the key fob or My BMW app to unlock if needed.

  2. 2

    Seat the connector firmly

    Push the CCS2 or Type 2 plug straight into the port until it clicks and locks. The charging port is on the rear right of the i5. Do not twist or angle the connector.

  3. 3

    Complete authentication at the charger

    Tap your RFID card, start the session in the charging app, or pay via contactless. The charger needs authorization before it sends power to your i5.

  4. 4

    Check iDrive for scheduling conflicts

    Open iDrive and navigate to Charging, then Charging Settings. If a departure time or scheduled window is active, switch to 'Charge Immediately' to override it.

  5. 5

    Unplug and reconnect

    Remove the connector, wait 15 seconds, then plug in again. This forces a new handshake between the i5 and the charger, which resolves many communication issues.

  6. 6

    Move to another charger

    If nothing works, the charger is likely faulty. Try another stall or station. Report the broken charger through the network app so others are warned.

BMW i5 Charging Payment Failed: Solutions That Work

Your BMW i5 is plugged in and ready, but the charger will not accept your payment. Whether it is an RFID card that gets no response, an app that throws an error, or a declined bank card, this stops you from charging. Here is how to get past it quickly.

Symptoms

  • Charger shows 'authentication failed' or 'payment error'
  • RFID card tap produces no response on the charger
  • Charging app fails to start the session with a payment error
  • Contactless bank card is declined at the charger terminal
  • Session starts but immediately cancels with a billing error

What to Do

  1. 1

    Switch to a different payment method

    Try another RFID card, a different charging app, or contactless bank card. Having at least two options means one failure does not strand you.

  2. 2

    Verify your account status

    Open the charging app and check your payment method, balance, and subscription status. Fix any issues before retrying.

  3. 3

    Check which networks this charger accepts

    Look for network logos on the charger unit. If your provider is not listed, you need ad-hoc payment or a different provider.

  4. 4

    Scan the QR code for ad-hoc payment

    Most modern European chargers have a QR code. Scan it with your phone to open a web-based payment page. You can pay with any credit or debit card, no app needed.

  5. 5

    Cancel and restart the session

    If the payment seemed to process but charging did not start, cancel the session in the app and try again. A fresh authorization attempt often works.

  6. 6

    Call the network's support number

    The charger should display a support phone number. The operator can sometimes authorize sessions remotely or troubleshoot billing issues in real time.

BMW i5 eDrive40 Charging Too Slow: Causes and Fixes

Your BMW i5 eDrive40 can charge at up to 205kW on a DC fast charger, which is impressive for a 400V car. But if you are seeing far lower numbers on the iDrive display, something is limiting the power. Most causes are easy to identify and fix.

Symptoms

  • DC charging power shown in iDrive is well below 205kW
  • Charging takes much longer than expected for the 81.2kWh battery
  • Speed drops drastically above 50% state of charge
  • AC charging is stuck at 11kW even at a 22kW station
  • iDrive displays a battery temperature warning or conditioning message

What to Do

  1. 1

    Check current power in iDrive

    Open the charging screen on iDrive to see the live kW figure, battery temperature, and estimated completion time. This tells you immediately whether the car or the charger is the limiting factor.

  2. 2

    Precondition the battery before arriving

    Enter the charging station as a destination in iDrive navigation. The i5 will automatically warm (or cool) the battery to optimal charging temperature while you drive. This can double your initial charging speed in winter.

  3. 3

    Choose a high-power charger

    Use the BMW app or a charger map to find stations rated at 200kW or above. Ionity, Fastned, and some Shell Recharge stations offer 300kW+ chargers that let the i5 reach its peak.

  4. 4

    Avoid power-sharing stalls

    At charger parks with paired stalls (A1/A2, B1/B2), choose a pair where the other stall is empty. This gives your i5 the full charger output.

  5. 5

    Charge in the optimal range

    Plan your stops to arrive between 5% and 15% and leave at 80%. This keeps you in the fastest part of the i5's charging curve and minimizes time per kWh added.

  6. 6

    Install software updates

    BMW pushes OTA updates that can improve charging performance. Check iDrive under Settings, then Software Update, and install any pending updates.

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.
