Mercedes-Benz EQS Charging at GreenWay

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-only payment with no backup option

GreenWay stations require the GreenWay app to start a session. There are no contactless card readers or RFID pads. If the app fails or your phone dies, you cannot charge.

Symptoms

• No card reader or RFID pad visible on the charger
• Charger screen shows a QR code or 'Use app to start' message
• You arrived without the app installed and cannot begin a session
• Your phone battery is low and you are worried it will die during setup

How to Fix It

1. 1

   Download the GreenWay app before your trip

   This is non-negotiable for GreenWay stations. Install the app, create an account, and add a payment method while you have good internet and battery. Do this before you leave, not at the charger.

2. 2

   Charge your phone before arriving at the station

   Since you need your phone to start and monitor the session, make sure it has enough battery. Use your car's USB port or a power bank on the way.

3. 3

   Try a roaming app as a backup

   Some GreenWay stations are accessible through roaming providers like Plugsurfing, Shell Recharge, or Chargemap. Check your roaming app's map to see if the specific station is covered before counting on it.

4. 4

   Scan the QR code on the charger

   If you do not have the app, scan the QR code with your phone camera. It may direct you to the app store or, in some cases, to a web-based session start page.

App requires location services for charger activation

The GreenWay app needs location services turned on to activate a charger. Without it, the app cannot verify that you are at the station and will not let you start a session.

Symptoms

• App shows 'Enable location services' and will not proceed
• You can see the charger on the map but cannot start a session
• The 'Start charging' button is grayed out or unresponsive
• App shows your location incorrectly, placing you far from the station

How to Fix It

1. 1

   Enable location services for the GreenWay app

   Go to your phone settings, find the GreenWay app, and set location access to 'While Using' or 'Always.' On iPhone: Settings, Privacy, Location Services, GreenWay. On Android: Settings, Apps, GreenWay, Permissions, Location.

2. 2

   Make sure GPS is turned on, not just Wi-Fi location

   In some areas, Wi-Fi-based location is inaccurate. Turn on full GPS (high accuracy mode on Android) for a precise position fix at the station.

3. 3

   Step outside your vehicle briefly

   If GPS signal is weak (underground parking, dense urban area), step a few meters away from your car with your phone. This can help the GPS lock onto your position.

4. 4

   Try selecting the charger manually

   If the app cannot determine your location, try tapping on the station on the map manually or entering the charger's ID number (printed on the charger unit). Some app versions allow manual selection as a fallback.

Coverage gaps between cities

GreenWay's network is concentrated in and around cities. Between major cities, especially on secondary roads, there can be long stretches with no GreenWay stations.

Symptoms

• No GreenWay stations shown on the app map for 100+ km stretches
• The nearest GreenWay station requires a detour off your route
• You planned a trip assuming GreenWay coverage and ran into a gap
• Available stations between cities are AC-only (slow), not DC fast charging

How to Fix It

1. 1

   Plan your route and charging stops before leaving

   Use the GreenWay app or a route planner like ABRP (A Better Route Planner) to map out charging stops. Identify gaps in advance so you are not caught by surprise.

2. 2

   Have alternative charging networks ready

   Install apps for other networks that operate in the region. In Slovakia and Poland, look for Ionity, Shell Recharge, or Greencharge. In Czech Republic, check CEZ or PRE. Having multiple apps ensures you always have a fallback.

3. 3

   Charge to a higher level before entering a gap

   If you know there is a 150+ km stretch without fast chargers, charge to 90 or even 95% at the last available station. The slower charging speed above 80% is worth it if the alternative is running out of range.

4. 4

   Check for AC chargers as emergency backup

   Hotels, shopping centers, and some gas stations in Central Europe have AC chargers (Type 2, 11 to 22 kW). These are slow but can add enough range to reach the next fast charger. Many are accessible through Chargemap or Plugsurfing.

Charger screen errors in local language only

When a GreenWay charger displays an error, the message is often in Slovak, Polish, or Czech with no English translation. Understanding what went wrong is difficult.

Symptoms

• Error message appears in Slovak, Polish, or Czech
• You cannot tell if the error is temporary or requires support
• The charger stopped and you do not know why
• The error code is visible but the description is in a language you do not read

How to Fix It

1. 1

   Note the error code, not just the text

   Most error messages include a numeric or alphanumeric code (like E-101 or ERR_04). Write down or photograph the code. This is useful for support and often means the same thing regardless of language.

2. 2

   Use your phone camera to translate the screen

   Open Google Translate or Apple Translate, switch to camera mode, and point it at the charger screen. This gives a real-time translation of the error message.

3. 3

   Try unplugging and restarting the session

   Many error messages clear on a retry. Unplug, wait 15 seconds, plug back in, and start a new session through the app. Common errors like 'Communication timeout' resolve themselves.

4. 4

   Contact GreenWay support with the error code

   If the error persists, contact support through the GreenWay app. Provide the error code and the station ID (printed on the charger). GreenWay support can tell you whether the issue is temporary or requires a technician.

Power limited at older installations

Some older GreenWay stations deliver less than 150 kW. They may be rated at 50 kW or have degraded power output due to aging hardware.

Symptoms

• Charging speed maxes out at 50 kW on a station advertised as 150 kW
• The charger label says 150 kW but your vehicle never receives more than 50 kW
• Speed is significantly lower than what you get at newer GreenWay stations
• The app shows the station as 150 kW but the charger hardware looks older

How to Fix It

1. 1

   Check the charger label for the actual rated power

   The charger unit itself has a label showing its maximum output. Older GreenWay units may be rated at 50 kW despite the station listing showing 150 kW (which may refer to a newer unit at the same location).

2. 2

   Check if the station has multiple charger types

   Some GreenWay stations have both older 50 kW and newer 150 kW chargers. Make sure you are plugged into the newer, higher-power unit. It is usually the larger cabinet.

3. 3

   Verify your vehicle's battery level and temperature

   Your vehicle limits charging speed when the battery is above 60 to 80% or when the battery is cold. Check your dashboard to confirm the car is requesting more than what the charger delivers.

4. 4

   Use a different station if speed matters

   If you need faster charging and the station is limited, check the GreenWay app for a newer station nearby. Filter by power level to find 150 kW units specifically.
