Why Your Charging Speed May Differ

The Mercedes-Benz EQB supports up to 102 kW DC charging. EnBW mobility+ chargers deliver up to 300 kW. Your car's maximum intake is the limiting factor here, capping speed at 102 kW even on a faster charger.

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

Mercedes-Benz EQB Charging Problems

Mercedes-Benz EQB Charger Won't Start: Quick Fixes

You have connected your Mercedes-Benz EQB to a public charger, but the session will not start. MBUX shows nothing, the charger sits idle, and you are wondering what is wrong. This is one of the most common complaints at public chargers, and it is usually fixable on the spot.

Symptoms

  • The charger screen stays on 'waiting' or 'connect vehicle' after plugging in
  • MBUX does not show any charging activity
  • The EQB's charge port LED does not illuminate
  • The charger returns an error code after you connect
  • The CCS2 connector does not click into place

What to Do

  1. 1

    Unlock the EQB and open the charge port

    Ensure the car is unlocked. Press the charge port flap to open it. On some EQB models, you can also open it through the Mercedes me app.

  2. 2

    Insert the connector firmly

    Push the CCS2 or Type 2 connector straight into the port until it clicks. The charge port is on the right side of the EQB. A locked connector triggers the charging protocol.

  3. 3

    Authenticate at the charger

    Tap your RFID card on the charger reader, start the session in the network app, or tap your bank card on the contactless terminal. The charger needs authorization before sending power.

  4. 4

    Disable scheduled charging in MBUX

    In MBUX, navigate to EV settings, then charging. If a schedule is set, switch to immediate charging so the EQB does not wait for a timer.

  5. 5

    Disconnect and retry

    Unplug the cable, wait 15 seconds, and reconnect. This forces a fresh handshake between the EQB and the charger.

  6. 6

    Try another charger

    If the charger remains unresponsive, it is likely out of service. Move to a different stall or station and report the faulty unit through the network's app.

Mercedes-Benz EQB Charging Payment Failed: Fix Now

You have connected your Mercedes-Benz EQB to a charger, but the payment will not go through. RFID not recognized, app error, or bank card declined. This is a charger-side issue, not an EQB problem, but it still blocks your session. Here is how to get charging.

Symptoms

  • The charger displays 'authentication failed' or 'payment declined'
  • Your RFID card tap produces no response
  • The charging app returns an error when starting a session
  • Contactless bank card payment is declined
  • The charger asks for payment but no method works

What to Do

  1. 1

    Try an alternative payment method

    Switch from RFID to the charging app, or from the app to a contactless bank card. Having multiple options ensures one failure does not strand you.

  2. 2

    Check your account status

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

  3. 3

    Verify the charger supports your network

    Look for provider logos on the charger. If yours is not there, you need ad-hoc payment via QR code or a different provider.

  4. 4

    Scan the QR code for ad-hoc payment

    Most European chargers have a QR code that opens a browser-based payment page. Pay with any bank card, no app needed.

  5. 5

    Cancel and restart the session

    If payment seemed to go through but charging did not start, cancel in the app and try again with a fresh authorization.

  6. 6

    Contact the network's support

    The charger should display a phone number. The operator can sometimes authorize sessions remotely or troubleshoot payment issues.

Mercedes-Benz EQB 350+ Charging Slow: How to Fix It

Your Mercedes-Benz EQB 350+ supports up to 102kW DC fast charging, which is moderate for its class. If the MBUX display is showing far less than that, every charging stop takes longer than it should. Here is what affects the EQB's charging speed and how to improve it.

Symptoms

  • DC charging power shown on MBUX is well below 102kW
  • Charging the 70.5kWh battery takes significantly longer than expected
  • Speed drops noticeably above 70% state of charge
  • AC charging is stuck below 11kW at a faster station
  • MBUX displays a battery temperature warning or conditioning indicator

What to Do

  1. 1

    Check charging power in MBUX

    Open the charging status screen on MBUX. It displays current kW, battery temperature, and estimated completion time. This tells you whether the car or charger is limiting speed.

  2. 2

    Precondition the battery before arriving

    Enter the charging station as a destination in MBUX navigation. The EQB will precondition the battery to optimal temperature while you drive. This is the single most effective step in cold weather.

  3. 3

    Find a charger rated at 100kW or more

    Use the Mercedes me app or a charger map to locate high-power stations. Ionity, Fastned, and some Shell Recharge stations offer 100kW+ chargers.

  4. 4

    Avoid power-sharing stalls

    Choose a charger pair where the adjacent stall is empty. This gives the EQB the full output of the charger.

  5. 5

    Charge between 10% and 80%

    Plan stops to arrive between 10% and 15% and leave at 80%. This keeps you in the EQB's fastest charging window.

  6. 6

    Check for software updates

    Mercedes releases over-the-air updates that can improve charging behavior. Check MBUX under Settings for available updates.

Common EnBW mobility+ Issues

Roaming pricing unclear or higher than expected

You started a session through EnBW mobility+ and the per-kWh price was significantly higher than you expected. The same charger costs different amounts at different times, and the pricing logic feels opaque.

Symptoms

  • Per-kWh rate on the receipt is higher than the rate shown on the EnBW website
  • Same charger location costs more through EnBW mobility+ than through the CPO's own app
  • Price differs between two chargers at the same station
  • Unexpected 'roaming fee' or 'session fee' on your invoice

How to Fix It

  1. 1

    Check the price before you start the session

    In the EnBW mobility+ app, tap on the charger and look for the pricing details before starting. The app shows the per-kWh rate for that specific charger. Prices vary because each CPO sets different roaming rates.

  2. 2

    Understand the pricing tiers

    EnBW mobility+ groups chargers into pricing tiers. 'EnBW own' chargers are cheapest, 'roaming standard' is mid-range, and 'roaming plus' (typically high-power chargers from premium CPOs like Ionity) costs more. The tier is usually shown in the charger details.

  3. 3

    Compare with the CPO's own app

    If a charger is operated by Ionity, for example, check the Ionity app or website for their direct pricing. Sometimes the CPO's own app or RFID card is cheaper because there is no roaming middleman. If you use that CPO frequently, their own account may save you money.

  4. 4

    Consider the EnBW mobility+ tariff you are on

    EnBW offers different tariffs (with and without a monthly fee). The tariff with a monthly fee usually gives lower per-kWh rates. In the app, go to your profile to check which tariff you are on and whether switching would save you money based on your usage.

  5. 5

    Watch for idle fees and blocking fees

    Some chargers accessed through EnBW mobility+ charge a per-minute fee after your car finishes charging but the cable is still plugged in. Move your car promptly once charging is complete to avoid these fees.

App not loading charger details

You tap on a charger pin on the map and the detail screen is blank, shows a loading spinner forever, or displays outdated information. You cannot see pricing, availability, or the start button.

Symptoms

  • Charger detail page shows a permanent loading spinner
  • Availability status not updating (shows 'Available' for hours at a busy station)
  • Price information missing from the detail screen
  • App shows 'No connection' error when loading charger details

How to Fix It

  1. 1

    Check your phone's internet connection

    Charging stations are often in areas with poor cellular coverage, like parking garages, highway rest stops behind concrete walls, or rural areas. Switch between mobile data and Wi-Fi, or walk to a spot with better signal and load the charger details there.

  2. 2

    Force-close the app and reopen it

    Swipe the EnBW mobility+ app away from your recent apps list, wait a few seconds, and reopen it. Navigate to the charger again. This clears any stuck network requests.

  3. 3

    Search for the charger by ID

    Instead of tapping the map pin, use the search bar in the app and enter the charger's ID or EVSE number (printed on the physical unit). This sometimes loads details that the map view fails to fetch.

  4. 4

    Use the QR code on the charger as a backup

    Many chargers have a QR code that opens a direct session start page. Scan it with your phone camera. This page is served by the CPO, not EnBW, and often loads faster.

  5. 5

    Clear the app cache

    On Android: Settings, Apps, EnBW mobility+, Storage, Clear Cache. On iOS: delete and reinstall the app (iOS does not offer cache clearing). This resolves issues caused by corrupted local data.

QR code scan not working

You scan the QR code on the charger with the EnBW mobility+ app and it either does not recognize the code, opens a wrong page, or shows an error.

Symptoms

  • App says 'QR code not recognized' after scanning
  • QR code opens a web page for the CPO's own app instead of EnBW mobility+
  • Camera does not focus on the QR code (too dark, code damaged)
  • Scan succeeds but the session start page shows an error

How to Fix It

  1. 1

    Use the EnBW app's built-in scanner, not your phone camera

    Open the EnBW mobility+ app and use its QR scanner (usually in the top menu or via a scan button on the map screen). Scanning with your phone camera might open the CPO's own page instead of routing through EnBW.

  2. 2

    Clean the QR code

    Wipe dirt, rain, or ice off the QR code with your sleeve. Damaged or faded QR codes are common on outdoor chargers. If the code is badly worn, look for a second QR code on a different part of the charger.

  3. 3

    Turn on your phone's flashlight

    In dark or shaded areas, the camera cannot read the code. Most QR scanners (including EnBW's) have a flashlight toggle. Enable it for better readability.

  4. 4

    Enter the charger ID manually

    If the QR code will not scan, look for the charger's numeric or alphanumeric ID printed nearby. Enter it manually in the EnBW app's search function to find and start the session.

Cannot stop the session from the app

You tap 'Stop Charging' in the EnBW mobility+ app and nothing happens. The session keeps running, your car keeps charging (or has already finished but the session stays active), and you want to unplug and leave.

Symptoms

  • 'Stop' button in the app does not respond or shows an error
  • Session shows as active in the app even after unplugging
  • Charger screen says 'Session active' but your car is full
  • You are worried about accumulating idle fees

How to Fix It

  1. 1

    Physically unplug the connector from your car

    On most chargers, unplugging the cable ends the session automatically, regardless of what the app says. Unlock your car's charge port (from the car's screen, key fob, or charge port button) and remove the connector.

  2. 2

    Wait 2 minutes and check the app again

    There is often a delay between physically ending the session and the app updating. The app depends on the CPO's system sending a 'session ended' signal back through the roaming chain. Give it a moment.

  3. 3

    Force-close and reopen the app

    Sometimes the app's session view gets stuck. Force-close it, reopen, and check your session history. The session may already be ended on the backend even if the active session screen was not updating.

  4. 4

    Press the stop button on the charger itself

    Many chargers have a physical stop button on the screen or housing. Press it. This sends the stop command directly to the charger hardware without going through the roaming network.

  5. 5

    Contact support if you are being billed for a stuck session

    If the session stays 'active' in the app for more than 10 minutes after you have unplugged and driven away, contact EnBW mobility+ support. They can close the session on their end and correct any overcharges.

App is in German and hard to navigate

The EnBW mobility+ app defaults to German. If you do not speak German, navigating menus, understanding pricing details, and finding settings can be frustrating.

Symptoms

  • All menus and buttons are in German after installation
  • Language setting not obvious in the app
  • Error messages appear in German, making troubleshooting difficult
  • Pricing terms and tariff explanations are only in German

How to Fix It

  1. 1

    Change your phone's system language temporarily

    The EnBW mobility+ app follows your phone's system language. If English is available in the app, switching your phone to English (Settings, General, Language) will switch the app too. You can switch back after you finish.

  2. 2

    Check for an English option in the app settings

    Open the app, tap the profile or menu icon (usually three lines or a person icon in the corner), and look for 'Sprache' (Language) or 'Einstellungen' (Settings). Some versions offer English as an option directly.

  3. 3

    Use your phone's translate feature on screenshots

    On iOS, take a screenshot and use Live Text to translate. On Android, use Google Lens. This is useful for understanding pricing details or error messages in German.

  4. 4

    Consider an alternative roaming app with better language support

    If the language barrier is a persistent problem, apps like Shell Recharge, Plugsurfing, or Chargemap offer similar roaming coverage across Europe and have full English interfaces. They access many of the same chargers.

EnBW mobility+ App Tips

  • Always check the per-kWh price in the charger details before starting a session. Roaming prices vary dramatically depending on which CPO operates the charger.
  • Save chargers you use regularly as favorites. This lets you quickly check availability and pricing on your usual routes without scrolling the map.
  • Download the app and set up your payment method at home, not at the charger. The registration process takes a few minutes and requires email verification.
  • If the app is slow or unresponsive at a charger, it is likely a cellular signal issue. Try loading the charger details while you still have good signal, before you arrive at the station.
  • The app shows which CPO operates each charger. Knowing this helps you understand pricing tiers and lets you contact the right support line if the hardware has a problem.

Payment Tips

  • EnBW mobility+ bills everything to the payment method in your account. You will not need a card at the charger itself. Make sure your payment method is up to date before a trip.
  • Compare EnBW tariffs before committing. The free tariff has higher per-kWh rates. The monthly-fee tariff pays off if you charge frequently, especially at EnBW's own stations.
  • Invoices are available in the app under your account or profile section. Download them monthly for expense tracking, especially if you charge a company car.
  • Roaming sessions may take 1-3 business days to appear on your invoice. Do not panic if a session is missing immediately after charging.
