Why Your Charging Speed May Differ

The Mercedes-Benz EQS supports up to 200 kW DC charging. EVBox chargers deliver up to 350 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 EVBox 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 EVBox Issues

EVBox app vs third-party operator confusion

You see an EVBox-branded charger and download the EVBox app, but the session will not start because the station is operated by a different company. Many EVBox chargers are hardware only, with a separate operator managing access and billing.

Symptoms

  • EVBox app does not show the station or cannot start a session
  • You created an EVBox account but the charger asks for a different app or RFID card
  • Charger has EVBox branding but the screen shows a different company name
  • QR code on the charger leads to a different operator's website or app

How to Fix It

  1. 1

    Check the operator name on the charger screen or signage

    Look at the charger display when it is idle. The operator name is usually shown on the welcome screen. Common operators using EVBox hardware include municipalities, parking companies, and energy providers.

  2. 2

    Scan the QR code on the charger

    The QR code leads to the operator's platform, not necessarily EVBox. Scan it to find out which app or website you need.

  3. 3

    Try a roaming RFID card

    If you have an RFID card from Shell Recharge, Chargemap, Plugsurfing, or another roaming provider, try tapping it. Many EVBox chargers accept roaming cards regardless of who operates them.

  4. 4

    Search for the station in a multi-network app

    Apps like Chargemap or Shell Recharge aggregate many operators. Search for the charger location and you should see which operator runs it and how to start a session.

  5. 5

    Download the correct operator's app

    Once you know who operates the station, download their app. The EVBox app only works for chargers that EVBox operates directly.

CHAdeMO connector availability varies

Some EVBox fast chargers have both CCS2 and CHAdeMO connectors, but the CHAdeMO connector may be out of service, removed, or restricted. CHAdeMO is being phased out in Europe and availability is declining.

Symptoms

  • CHAdeMO connector is physically present but does not work
  • Charger screen shows CHAdeMO as 'Unavailable' or 'Out of Order'
  • CHAdeMO connector has been removed and the port is capped
  • App shows CHAdeMO available but the physical connector is missing

How to Fix It

  1. 1

    Check the charger before relying on CHAdeMO

    If your vehicle uses CHAdeMO, visually confirm the connector is present and functional at the station before planning your stop. App data may not reflect recent hardware changes.

  2. 2

    Try the CHAdeMO connector even if the app status is unclear

    Plug in and attempt to start a session. Sometimes the app shows a stale status but the connector works fine.

  3. 3

    Have a CCS2 adapter as a long-term solution

    If your vehicle only has CHAdeMO (common in older Nissan Leafs and some Mitsubishi models), CHAdeMO infrastructure is shrinking across Europe. A CHAdeMO-to-CCS2 adapter may be worth investigating for your specific vehicle.

  4. 4

    Filter for CHAdeMO in your charging app

    When planning a route, filter specifically for stations with verified CHAdeMO connectors. User reviews and recent check-ins are more reliable than operator listings for CHAdeMO availability.

RFID card registration process unclear

To use an RFID card at EVBox-operated stations, you may need to register the card through the EVBox platform first. The registration process is not always obvious.

Symptoms

  • New RFID card does not work at the charger even after ordering it from EVBox
  • Card works at other networks but not at EVBox-operated stations
  • You received a card but there are no activation instructions
  • Online portal asks for a card number format you do not recognize

How to Fix It

  1. 1

    Check the activation email

    When you order an RFID card from EVBox, they send an activation email. Check your inbox and spam folder. The email contains a link to activate the card in your EVBox account.

  2. 2

    Add the card in the EVBox app or portal

    Log in to your EVBox account (app or web portal). Navigate to 'My cards' or 'Charge cards' and add the card using the number printed on it. The card does not work until it is linked to your account.

  3. 3

    Wait for activation to propagate

    After registering the card, it may take up to 24 hours for the activation to reach all chargers. If the card does not work immediately after registration, try again the next day.

  4. 4

    Use the app as a backup while the card activates

    You can start sessions through the EVBox app while waiting for your RFID card to activate. Tap 'Start charging' in the app and select the charger.

Charger offline due to firmware update

EVBox periodically pushes firmware updates to their chargers. During an update, the charger is temporarily unavailable. This can happen without warning and usually lasts 10 to 30 minutes.

Symptoms

  • Charger screen shows 'Updating' or 'Maintenance' message
  • Charger was working a few minutes ago but now shows as offline
  • App shows the charger as unavailable with no estimated return time
  • Multiple chargers at the same location are all offline simultaneously

How to Fix It

  1. 1

    Wait 10 to 15 minutes

    Firmware updates on EVBox chargers usually complete within 10 to 30 minutes. If the charger shows an update message, it will likely come back online shortly.

  2. 2

    Try another charger at the same location

    Firmware updates sometimes roll out one unit at a time. If there are multiple chargers, others may still be operational.

  3. 3

    Check the app for status updates

    The operator's app or the EVBox app may show whether the outage is a scheduled update or an unexpected fault. Scheduled updates usually have an estimated completion time.

  4. 4

    Move to an alternative station if you cannot wait

    If you need to charge immediately and the update is taking longer than expected, use a multi-network app to find the nearest available charger from any network.

Power sharing between connectors reduces speed

Some EVBox fast chargers share their power output between two connectors. When both are in use, each vehicle receives roughly half the charger's maximum power.

Symptoms

  • Charging speed drops by half when a second car plugs into the same unit
  • Dashboard shows 75 kW at a charger rated for 150 kW
  • Speed suddenly increases when the car on the other connector finishes
  • One side of the charger consistently delivers more power than the other

How to Fix It

  1. 1

    Check if both connectors are on the same unit

    EVBox dual-connector chargers share one power module. If both CCS2 cables come from the same physical cabinet, they share power. Two separate cabinets are two independent chargers.

  2. 2

    Choose an unoccupied charger unit if available

    If multiple charger units are available, pick one where the other connector is not in use. You will get the full rated power to yourself.

  3. 3

    Understand how power sharing works

    Power sharing is dynamic. The charger allocates power based on what each vehicle can accept. If the other vehicle is at 80% and barely drawing power, you may get most of the charger's output even while sharing.

  4. 4

    Wait for the other car to finish

    If your speed is reduced by sharing, it will increase when the other vehicle finishes. Check your dashboard periodically. The speed change happens automatically without any action from you.

  5. 5

    Check your vehicle's own limits first

    Before assuming power sharing is the issue, verify that your car is not limiting the speed due to battery temperature, state of charge above 80%, or its own maximum DC charging rate.

EVBox App Tips

  • The EVBox app only works for chargers operated by EVBox directly. Most EVBox-branded chargers are operated by other companies. Always check the operator name on the charger first.
  • If you see an EVBox charger, scan the QR code before downloading any app. It will tell you which operator's platform you actually need.
  • For EVBox-operated stations, the app shows real-time connector status, power output, and session cost. Use it to monitor your session remotely.
  • Register your RFID card in the EVBox app or web portal before trying to use it. Unregistered cards are not recognized by the chargers.

Payment Tips

  • RFID cards from major roaming networks work at most EVBox chargers regardless of operator. Shell Recharge, Chargemap, and Plugsurfing have good coverage.
  • If your RFID card fails, check which company operates the station. The EVBox app may not help if someone else runs the charger.
  • EVBox-operated stations show pricing on the charger screen before you start. Rates vary by location and time of day at some stations.
  • For EVBox-operated chargers, you can link a payment method in the EVBox app for seamless billing. Invoices are available in your account.
