Why Your Charging Speed May Differ

The Mercedes-Benz EQS supports up to 200 kW DC charging. Fastned chargers deliver up to 400 kW. Your car's maximum intake is the limiting factor here, capping speed at 200 kW even on a faster charger.

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

Mercedes-Benz EQS Charging Problems

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.

Common Fastned Issues

Autocharge not recognizing your vehicle

You have Autocharge set up in the Fastned app, but when you plug in, the charger asks for payment instead of starting automatically.

Symptoms

  • Charger screen prompts for app or card payment after plugging in
  • Screen shows 'Vehicle not recognized' or goes straight to the payment screen
  • Autocharge worked at other Fastned stations but not this one
  • You recently changed your vehicle or payment method in the Fastned app

How to Fix It

  1. 1

    Check Autocharge status in the Fastned app

    Open the Fastned app, go to your account or Autocharge settings, and verify that Autocharge is toggled on and linked to your current vehicle. If you switched vehicles recently, you may need to re-register the new one.

  2. 2

    Unplug, wait 15 seconds, and plug in again

    The Autocharge handshake happens in the first few seconds. If the timing was off or the connector was not fully seated, the charger defaults to manual payment. Try again with a firm, steady plug-in.

  3. 3

    Make sure your payment method is valid

    Autocharge bills your saved payment method automatically. If the card on file has expired or been blocked, Autocharge will fail even though your vehicle is recognized. Update your payment details in the Fastned app.

  4. 4

    Verify your vehicle supports Autocharge

    Autocharge requires the vehicle to transmit a unique identifier through the charging cable (MAC address). Most newer EVs support this, but some older models or specific firmware versions do not. Check Fastned's website for a compatibility list.

  5. 5

    Start the session via the app as a workaround

    If Autocharge is not cooperating, open the Fastned app, select the station and charger, and start the session manually. You will still get your Gold Member or regular pricing.

Contactless card reader not responding

You tap your debit or credit card on the contactless reader, but nothing happens. No beep, no screen change, no error.

Symptoms

  • No response from the reader when tapping a card
  • Reader beeps but the screen shows 'Transaction failed'
  • Card works at shops and other chargers but not at this Fastned station
  • Apple Pay or Google Pay does not trigger the reader

How to Fix It

  1. 1

    Locate the correct reader

    Fastned chargers have the contactless reader built into the charger unit. It is usually a small pad with the contactless symbol near the screen. Make sure you are tapping on the reader, not on the screen itself.

  2. 2

    Hold your card still for 3 to 5 seconds

    Do not tap and remove quickly. Hold the card flat against the reader and wait. Some readers are slower than retail terminals.

  3. 3

    Remove your card from its wallet or phone case

    Other cards, RFID badges, or phone cases with magnets can interfere with the contactless signal. Try the card on its own, directly on the reader.

  4. 4

    Try a different card

    Some card issuers block pre-authorization transactions above a certain threshold. Fastned may pre-authorize 100 EUR or more. If your card's contactless limit is lower, the transaction fails.

  5. 5

    Use the Fastned app instead

    If the contactless reader is faulty, start the session through the Fastned app. You can also use a roaming RFID card from providers like Shell Recharge or Chargemap.

Charger cable too short for your vehicle

The charging cable attached to the Fastned station does not reach your vehicle's charge port. This depends on your vehicle's port position and how you park.

Symptoms

  • Cable reaches the port but is stretched tight with no slack
  • Cable does not reach at all when parked normally
  • You need to reverse in or park at an awkward angle
  • Cable reaches but the connector presses against the car body at a sharp angle

How to Fix It

  1. 1

    Reposition your vehicle

    Try parking closer to the charger or at a different angle. If your charge port is on the front left, back in so the port is closest to the cable. Many Fastned stations are designed for pull-through parking.

  2. 2

    Try the other cable

    Fastned chargers typically have two cables (CCS2 and CHAdeMO, or two CCS2 cables from different sides). The cable on the other side of the charger may reach more easily.

  3. 3

    Try a different charger at the same station

    If the station has multiple charger units, another one may give you a better angle. Charger positions vary slightly across units.

  4. 4

    Do not force a stretched cable

    A cable under tension can damage the connector, your charge port, or the cable itself. If it does not reach comfortably, reposition the car. A damaged connector can shut down the charger for everyone.

Speed throttling when multiple vehicles are charging

Your charging speed drops when other vehicles start charging at the same Fastned station. This is power sharing in action.

Symptoms

  • Charging started at 150 kW and dropped to 80 kW when another car plugged in
  • Speed is lower at a busy station than at the same station when it was empty
  • Dashboard shows the charger is limiting power, not the battery
  • Speed fluctuates as other vehicles arrive and leave

How to Fix It

  1. 1

    Understand how Fastned power sharing works

    Most Fastned stations have a total power budget shared across all active chargers. When more vehicles charge simultaneously, each one gets a smaller share. This is a station design limitation, not a fault.

  2. 2

    Charge during off-peak hours if possible

    Fastned stations along highways are busiest during weekend travel peaks and holiday periods. Early morning or late evening sessions often mean you have the station to yourself and get full speed.

  3. 3

    Choose a station with more capacity

    Newer Fastned stations and recently upgraded locations tend to have larger power budgets. The Fastned app shows the maximum kW per station. Stations rated at 400 kW per charger usually have more headroom than 150 kW stations.

  4. 4

    Do not wait for full speed. Charge what you need and go.

    Even at reduced speed, DC fast charging is much faster than AC. If you are getting 80 kW instead of 150 kW, it takes a few extra minutes, not hours. Charge to 80% and continue your trip.

Busy station with no queue management

You arrive at a Fastned station and all chargers are occupied. There is no official way to join a queue or reserve a spot.

Symptoms

  • All chargers are in use and multiple cars are waiting
  • No clear queue order. Confusion about who arrived first.
  • App does not show how many vehicles are waiting
  • You are not sure if you should wait or drive to another station

How to Fix It

  1. 1

    Check the Fastned app for nearby alternatives

    Before committing to a wait, check if there is another Fastned station or competitor fast charger within 10 to 15 minutes. Waiting 20 minutes for a spot is often slower than driving to a nearby empty station.

  2. 2

    Communicate with other waiting drivers

    Fastned does not have a formal queue system. If you decide to wait, make yourself visible by parking near the charger area and, if comfortable, let other waiting drivers know you are in line. Brief eye contact and a nod go a long way.

  3. 3

    Watch for vehicles at high state of charge

    If a vehicle on the charger is already above 80%, it will likely leave soon. Drivers charging from 80 to 100% at a DC fast charger are rare. Most will unplug and leave within minutes.

  4. 4

    Plan stops to avoid peak times

    Holiday weekends, Friday afternoons, and Sunday evenings are the busiest. If your schedule is flexible, adjusting departure time by an hour or two can make a significant difference in charger availability.

  5. 5

    Send feedback to Fastned

    Fastned expands stations based on utilization data. If a station is consistently full, reporting it through the app helps Fastned prioritize adding more chargers at that location.

Fastned App Tips

  • Set up Autocharge in the Fastned app before your first visit. When it works, you just plug in and walk away. No tapping, no scanning.
  • The Fastned app shows real-time availability per station. Green dots mean available, red means occupied. Check before you drive there.
  • If you are a Fastned Gold Member, make sure you are logged in when starting a session through the app. Otherwise you will be charged the standard rate.
  • Fastned stations show live pricing in the app. Gold Member pricing and standard pricing are displayed separately so you know exactly what you will pay.
  • Use the Fastned app to track your charging history. Every session shows energy delivered, peak speed, session duration, and total cost.
  • The app lets you report charger issues directly. If a cable is damaged or a charger is not working, reporting it helps Fastned send maintenance faster.

Payment Tips

  • Fastned offers a Gold Member subscription that gives you a lower per-kWh rate at every Fastned station. Check the Fastned app for current pricing in your country. If you charge at Fastned more than two or three times a month, it usually pays for itself.
  • Contactless payment is available at all Fastned stations. Pre-authorization holds are typically around 100 EUR and release within a few business days.
  • You can also charge at Fastned using a roaming RFID card (Shell Recharge, Chargemap, NewMotion, and others). But roaming rates are usually higher than Fastned's direct pricing.
  • Fastned Gold Member pricing applies to Autocharge and app-initiated sessions. If you pay with a contactless card at the charger, you get the standard (non-member) rate.
  • Fastned may charge idle or overstay fees at some locations. Check the Fastned app or tariff page for current policies. Unplugging promptly when your session is complete is both courteous and avoids potential extra charges.
