Mercedes-Benz EQS Charging at Shell Recharge

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.

RFID card not recognized at the charger

You tap your Shell Recharge RFID card on the charger's reader but it does not respond, beeps an error, or shows 'Card not recognized.'

Symptoms

• Charger beeps but displays 'Unknown card' or 'Authorization failed'
• No response at all when tapping the card
• Card works at some stations but not others
• Card worked yesterday at the same charger but does not work today

How to Fix It

1. 1

   Hold the card still on the reader for 3 to 5 seconds

   RFID readers at some chargers are slow. Do not tap and remove quickly. Hold the card flat against the reader and wait for a confirmation beep or screen change.

2. 2

   Check that your RFID card is activated

   New Shell Recharge RFID cards must be activated in the Shell Recharge app before first use. Go to the app, find the RFID section, and make sure the card status shows active.

3. 3

   Try starting the session through the app instead

   Open the Shell Recharge app, find the station, select the charger, and start the session digitally. This bypasses the RFID reader entirely and uses the roaming connection.

4. 4

   Check if the CPO supports Shell Recharge roaming

   Not every charger that appears in the Shell Recharge app accepts the Shell Recharge RFID card. Some chargers only accept app-based roaming. The station details in the app usually indicate which payment methods are supported.

5. 5

   Clean the card and try again

   Dirt, scratches, or a phone case between the card and reader can block the RFID signal. Remove the card from any holder, wipe it, and try again on the reader's sweet spot (often marked with a contactless symbol).

Roaming vs direct pricing confusion

The price you pay through Shell Recharge is different from the price shown on the charger's screen. This is because Shell Recharge adds a roaming markup on top of the CPO's base rate.

Symptoms

• Charger screen shows 0.39 EUR/kWh but Shell Recharge bills 0.55 EUR/kWh
• Invoice includes fees not displayed at the charger (session fee, per-minute fee)
• Same station is cheaper when using the CPO's own app
• Pricing in the Shell Recharge app does not match the final invoice

How to Fix It

1. 1

   Check the Shell Recharge app for the roaming price before starting

   Before you tap your card or start a session, open the Shell Recharge app and select the station. The app shows the Shell Recharge price, which includes any roaming fee. This is the price you will actually pay.

2. 2

   Understand the pricing structure

   Shell Recharge typically charges a per-kWh rate plus sometimes a session start fee or per-minute fee. The charger screen shows the CPO's direct price, not the roaming price. These are two different rates for two different billing relationships.

3. 3

   Consider using the CPO's own app for lower rates

   If you charge at the same network regularly (for example, Allego, Fastned, or EnBW), their own app usually offers a lower price than roaming through Shell Recharge. The trade-off is managing multiple apps.

4. 4

   Download your invoice from the Shell Recharge app

   Go to your charging history in the Shell Recharge app. Each session has a detailed breakdown showing energy delivered, per-kWh rate, session fees, and total cost. Compare this with what you expected.

Session not starting via QR code

You scan the QR code on the charger to start a session through the Shell Recharge app, but nothing happens or you get an error.

Symptoms

• QR code opens the Shell Recharge app but shows 'Station not found'
• QR code opens a web page instead of the app
• App shows 'Unable to start session' after scanning
• QR code is faded, damaged, or partially covered by a sticker

How to Fix It

1. 1

   Search for the station manually in the app

   If the QR code does not work, open the Shell Recharge app, search for the station by name or location, and start the session from the station page. You may need to select the specific connector or charger ID.

2. 2

   Check the charger ID number

   Every charger has an ID printed somewhere on the unit (usually near the QR code or on a label). Enter this ID manually in the Shell Recharge app if the QR scan fails.

3. 3

   Make sure the QR code belongs to Shell Recharge

   Many chargers have multiple QR codes from different roaming providers and the CPO itself. Make sure you are scanning the Shell Recharge QR code, not the CPO's own code. Scanning the wrong code opens the wrong app or website.

4. 4

   Try the RFID card or contactless payment instead

   QR code start is just one method. Tap your Shell Recharge RFID card or use contactless payment if the charger supports it.

5. 5

   Check your internet connection

   Starting a session via QR code requires the app to communicate with Shell Recharge's servers and the CPO's backend. If you have weak mobile signal (common at highway rest stops), the request may time out. Try switching between Wi-Fi and mobile data.

App showing wrong charger status

The Shell Recharge app shows a charger as available, occupied, or offline, but the actual status is different when you arrive.

Symptoms

• App shows 'Available' but the charger is out of order or has an error screen
• App shows 'Occupied' but no vehicle is connected
• Status has not updated for hours and seems stale
• App shows fewer chargers at a station than physically exist

How to Fix It

1. 1

   Understand that status data is delayed

   Shell Recharge gets charger status from the CPO's systems through the roaming connection. This data can lag by 5 to 15 minutes. A charger that just became available may still show as occupied in the app.

2. 2

   Try plugging in regardless of app status

   If you are already at the station and a charger looks physically available (no vehicle connected, no error on screen), try plugging in and starting a session. The real-time status at the charger overrides whatever the app shows.

3. 3

   Check the CPO's own app for more accurate status

   The CPO (the company that actually operates the charger) usually has more accurate real-time status than roaming aggregators like Shell Recharge. If accuracy matters, cross-check with the CPO's app or website.

4. 4

   Report the incorrect status

   Use the Shell Recharge app to report the charger issue. This helps improve status accuracy over time.

Billing discrepancy between Shell Recharge and the CPO

The amount billed by Shell Recharge does not match what you expected based on the energy delivered or the session duration. This can happen because of how roaming billing works.

Symptoms

• Billed for more kWh than your vehicle's dashboard shows
• Charged a session fee you did not expect
• Per-minute idle fee added even though you unplugged on time
• Double charge: both Shell Recharge and the CPO billed you

How to Fix It

1. 1

   Compare the Shell Recharge invoice with your vehicle's data

   Your vehicle's dashboard shows how much energy the battery received. The charger meters how much energy it delivered, which includes conversion losses. A 5 to 10% difference is normal.

2. 2

   Check for per-minute fees

   Some CPOs charge a per-minute fee (for time spent connected) on top of the per-kWh fee. This can be especially costly during slow AC charging sessions. Check the pricing breakdown in the Shell Recharge app.

3. 3

   Look for session or start fees

   Some stations add a fixed fee per session (for example, 0.35 EUR to 1.00 EUR). This appears in the Shell Recharge invoice as a separate line item.

4. 4

   Dispute the charge through the Shell Recharge app

   If the amount is clearly wrong (double billed, charged for a session that never started, or obviously excessive), contact Shell Recharge support through the app. Go to your charging history, select the session, and use the dispute or help option.

5. 5

   Keep your vehicle's charge data as evidence

   Take a photo of your vehicle's charging screen or dashboard showing the kWh received and the session duration. This is useful if you need to dispute a charge.
