Mercedes-Benz EQS Charging at EnBW mobility+

Mercedes-Benz EQS Charger Won't Start a Session

You connected the CCS2 cable to your EQS's right rear charge port, but the Hyperscreen shows no charging activity. No power flowing, no progress. This is frustrating, especially in a flagship sedan where everything should just work. The cause is usually authentication, cable seating, or the charger itself, not the EQS.

Symptoms

• CCS2 connector plugged in but the Hyperscreen shows no charging activity
• Charger screen displays an error or stays idle after authentication attempt
• Plug & Charge does not authenticate automatically at a supported station
• Charge port LED does not illuminate or blinks an error pattern
• Mercedes me app shows the EQS as connected but not charging

What to Do

1. 1

   Remove and firmly reseat the CCS2 connector

   Pull the connector out of the right rear charge port. Check for debris or moisture. Push it back in straight and firm until you hear a click and see the charge port LED respond. The CCS2 connector is heavy, so support it with both hands to ensure proper alignment.

2. 2

   Authenticate manually if Plug & Charge failed

   Open the charging network's app and start the session by scanning the QR code or selecting the charger. If you have an RFID card for this network, tap it on the reader. Do not wait for Plug & Charge if it did not work within 30 seconds.

3. 3

   Disable scheduled charging in MBUX

   On the Hyperscreen, open Settings, then Charging. Turn off any departure time or scheduled charging window. At a public charger, you want charging to start immediately. Re-enable scheduled charging when you are back at your home wallbox.

4. 4

   Lock and unlock the EQS to reset the charge controller

   Use the key or Mercedes me app to lock the car. Wait 15 seconds, then unlock. This resets the charge port locking mechanism and the onboard charging communication module. Reconnect the cable after unlocking.

5. 5

   Try a different connector or charger at the station

   If the station has multiple CCS2 connectors, try a different one. If the entire station seems unresponsive, use MBUX navigation to find another nearby charger. Report the faulty charger through the network's app.

Mercedes-Benz EQS Payment Failed at Charging Station

You are standing next to your EQS at a public charger and payment will not go through. Plug & Charge did not activate, the app shows an error, or your card was declined. Payment failures are one of the most common reasons charging sessions do not start. With the EQS, you have multiple authentication options to try before giving up.

Symptoms

• Plug & Charge does not authenticate when the CCS2 cable is connected
• Contactless card declined at the charger's payment terminal
• Mercedes me Charge or the network's app shows a payment error
• RFID card not recognized by the charger reader
• Session starts but stops immediately with a billing-related error

What to Do

1. 1

   Try Plug & Charge by connecting the cable

   Plug the CCS2 connector into the EQS's right rear charge port. Wait up to 30 seconds for Plug & Charge to authenticate. Check the Hyperscreen for a charging confirmation. If nothing happens after 30 seconds, Plug & Charge is not working at this station.

2. 2

   Use the charging network's app to start the session

   Open the app for the charging network shown on the charger. Scan the QR code or enter the charger ID. Start the session through the app. Verify your payment method in the app is valid and not expired.

3. 3

   Try contactless payment at the charger terminal

   If the charger has a contactless payment terminal, tap your bank card, Apple Pay, or Google Pay. If the first card is declined, try a different one. Some terminals accept only certain card brands.

4. 4

   Verify your Mercedes me Charge account

   Open the Mercedes me app. Go to Charge settings and check that Plug & Charge is enabled and your payment method is current. If you recently changed your payment method, it may need time to sync. Try restarting the Mercedes me app.

5. 5

   Try a different RFID card or roaming provider

   If you carry multiple RFID cards, try another network. Roaming providers with broad European coverage (Chargemap, Maingau, Shell Recharge) can fill gaps where Mercedes me Charge does not reach.

6. 6

   Find an alternative charger nearby

   If payment fails on this charger entirely, use the Hyperscreen to find another station nearby. A different charging network may accept your payment method. Filter by the networks you know work with your cards.

Mercedes-Benz EQS Charging Slower Than Expected

You plugged in your EQS at a 300 kW charger expecting close to 200 kW, but the Hyperscreen shows 50 kW. Or your home wallbox is stuck at 3.6 kW instead of 11 kW (or 22 kW if you have the optional upgrade). The EQS has a huge 118 kWh battery that can take a while to warm up. Slow charging is almost always temperature, state of charge, or the charger, not a defect.

Symptoms

• DC fast charging speed well below the 200 kW maximum shown on the Hyperscreen
• AC charging stuck at 3-4 kW instead of 11 kW or 22 kW
• Charging speed drops sharply after reaching 50-60% state of charge
• Charging session starts at reasonable speed but slows within minutes
• The 118 kWh battery takes significantly longer to charge than expected

What to Do

1. 1

   Route to the charger using MBUX navigation

   Enter the charging station as your destination on the Hyperscreen or MBUX. This activates automatic battery preconditioning for the 118 kWh pack. The EQS will display a preconditioning notification. Given the large battery, start routing at least 20-30 minutes before arrival for maximum benefit in cold weather.

2. 2

   Check your state of charge before expecting peak speed

   The EQS reaches 200 kW only at lower state of charge levels. For the fastest DC charging, arrive between 10-20%. If you are above 60%, the speed reduction is normal. With 580 km of range, you often do not need to charge above 80% on road trips.

3. 3

   Verify the charger can deliver the speed you expect

   Check the charger's rated output on the unit itself or in the charging app. A 50 kW charger will never give your EQS more than 50 kW. Look for chargers rated 150 kW or higher to take advantage of the EQS's capabilities. Avoid stalls paired with another vehicle.

4. 4

   Check AC charging settings and wallbox compatibility

   Open the charging settings in MBUX. Confirm the charge current is set to maximum. If you have the optional 22 kW onboard charger, verify your wallbox is 3-phase 32A. For the standard 11 kW charger, you need at least 3-phase 16A.

5. 5

   Check if Plug & Charge negotiated the correct power

   The EQS supports Plug & Charge. Occasionally, authentication issues cause the charger to default to a lower power tier. Unplug from the right rear charge port, wait 30 seconds, and reconnect. Check MBUX for any authentication errors.

6. 6

   Try a different charger

   If the speed is still low after checking all settings, try a different charger. Some chargers degrade over time. Use MBUX navigation or the Mercedes me app to find a high-power charger (150 kW+) nearby.

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.
