Mercedes-Benz EQS Charging at Le Plein

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.

App and charger interface only in French

The Le Plein app and the charger screen interface are primarily in French. If you do not read French, navigating menus and understanding error messages takes extra effort.

Symptoms

• The app menus, buttons, and instructions are entirely in French
• The charger screen shows an error message you cannot read
• You cannot find the 'start session' button because the labels are in French
• Support articles and FAQ in the app are in French only

How to Fix It

1. 1

   Learn the key French charging terms

   A few words go a long way. 'Démarrer' means start, 'Arrêter' means stop, 'Brancher' means plug in, 'En charge' means charging, 'Disponible' means available, 'Hors service' means out of order. With these, you can navigate most screens.

2. 2

   Use your phone's translation feature on the charger screen

   Most smartphones can translate text from a photo. Point your camera at the charger screen and use Google Translate, Apple Translate, or a similar app to read the message. This works well for error messages you do not recognize.

3. 3

   Set up the session flow before you arrive

   Open the Le Plein app at home and familiarize yourself with the session flow: find station, select charger, start session. Once you know where the buttons are, the French labels matter less.

4. 4

   Use your phone's built-in app translation if available

   On Android, you can translate app interfaces using the system translation feature. On iOS, you can take a screenshot and translate it. This helps with menus and settings you need to navigate once.

RFID card ordering process through the app

Le Plein RFID cards can only be ordered through the app. There is no option to buy one at a station or from a retail location. The ordering and activation process has a few steps that can trip people up.

Symptoms

• You want an RFID card but cannot find where to order it
• You ordered a card but it has not arrived after the expected delivery time
• Your RFID card arrived but does not work at the charger
• The app says your card is active but the charger does not recognize it

How to Fix It

1. 1

   Order the card through the Le Plein app account section

   Open the Le Plein app, go to your account or profile settings, and look for an RFID card or badge option. Follow the ordering flow, which will ask for your delivery address. Delivery takes several business days within France.

2. 2

   Activate the card in the app after it arrives

   When the card arrives, you may need to activate it in the Le Plein app by entering the card number or scanning it. Check the instructions that came with the card. An unactivated card will not start a session.

3. 3

   Make sure your payment method is valid

   The RFID card charges sessions to the payment method saved in your Le Plein account. If your saved card has expired or been declined, the RFID card will not work even though it is activated. Update your payment details in the app.

4. 4

   Use the app to start sessions while waiting for the RFID card

   You do not need the physical RFID card to charge. The Le Plein app can start sessions directly. Use the app until your card arrives and is activated.

Station coverage concentrated in certain French regions

Le Plein's network does not cover all of France equally. Some regions have good coverage while others have very few or no stations. This can be a problem on longer trips.

Symptoms

• The app shows no Le Plein stations along a section of your route
• Stations are clustered around certain cities but absent in rural areas between them
• You planned a trip assuming Le Plein coverage and found a gap
• The nearest Le Plein station is far from your destination

How to Fix It

1. 1

   Check Le Plein coverage along your entire route before departing

   Open the Le Plein app and trace your route on the map. Look for gaps where there are no stations for long stretches. Identify these gaps before you leave, not when your battery is low.

2. 2

   Install backup charging apps for other French networks

   France has several other charging networks, including Ionity, TotalEnergies, Fastned, and local operators. Having apps for two or three networks ensures you always have a fallback when Le Plein coverage runs out.

3. 3

   Use a roaming RFID card for multi-network access

   A roaming card from Chargemap or another aggregator can access chargers from multiple French networks. This is especially useful in areas where Le Plein has no presence.

4. 4

   Plan with a multi-network route planner

   A Better Routeplanner (ABRP) or Chargemap show stations from all networks. Enter your vehicle and destination to get charging stops that work regardless of the operator.

Charger screen errors you cannot decipher

When something goes wrong at a Le Plein charger, the error message on the screen is in French. If you do not understand the message, you cannot tell whether to retry or move on.

Symptoms

• The screen shows an error code or message in French after you plug in
• The charger stopped mid-session and the screen displays a French message
• You see 'Hors service' or 'Erreur' but do not know the specific problem
• The screen shows instructions you cannot follow

How to Fix It

1. 1

   Photo-translate the error message

   Take a photo of the screen and use Google Translate's camera feature or Apple Translate to read it. This gives you the specific error, not just a guess.

2. 2

   Know the most common French charger errors

   'Hors service' means out of order, do not wait. 'Erreur de communication' means a communication error between charger and vehicle, try replugging. 'Session en cours' means a session is already active, possibly from a previous user who did not end it. 'Veuillez patienter' means please wait.

3. 3

   Try unplugging and reconnecting

   Many charger errors clear themselves when you unplug, wait 30 seconds, and plug in again. This resets the communication between your vehicle and the charger.

4. 4

   End any stuck session in the Le Plein app

   If the charger thinks a session is still active from a previous user, you may not be able to start a new one. Check the app to see if there is an active session on that charger. Sometimes you need to wait for it to time out.

5. 5

   Move to another charger if the error persists

   If the same error appears after two or three attempts, the charger likely has a hardware or software issue. Try another charger at the same station, or drive to the next Le Plein or alternative station.

Support phone line in French only

Le Plein's support phone line is staffed by French-speaking agents. If you need help at a station and do not speak French, communication can be difficult.

Symptoms

• You called support and the agent speaks only French
• The automated phone menu is in French with no language option
• You cannot explain your problem over the phone
• You need urgent help at a station but cannot communicate effectively

How to Fix It

1. 1

   Try the app's support or help section first

   Written support through the app (email, contact form, or chat) gives you time to use a translation tool. Type your question in English, translate it to French, and paste it. This is often more effective than a phone call.

2. 2

   Prepare a few key phrases in advance

   If you may need to call, have these ready: 'La borne ne fonctionne pas' (the charger is not working), 'Le câble est bloqué' (the cable is stuck), 'J'ai besoin d'aide' (I need help), and the station number or location name.

3. 3

   Use a real-time translation app during the call

   Google Translate's conversation mode can translate speech in both directions. It is not perfect, but it helps bridge the gap. Open it before you call.

4. 4

   Ask a nearby person for help if available

   If you are at a station and someone nearby speaks both French and your language, asking for a quick translation assist is perfectly reasonable. Most people are happy to help.
