Why Your Charging Speed May Differ

The Mercedes-Benz EQA supports up to 102 kW DC charging. EVBox chargers deliver up to 350 kW. Your car's maximum intake is the limiting factor here, capping speed at 102 kW even on a faster charger.

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

Mercedes-Benz EQA Charging Problems

Mercedes-Benz EQA Charger Won't Start a Session

You connected the cable to your EQA's right rear charge port, but nothing happens. No charging animation on MBUX, no power flowing. This is one of the most frustrating situations at a public charger, but it is almost always fixable on the spot. The cause is usually authentication, cable locking, or the charger itself.

Symptoms

  • CCS2 connector plugged in but MBUX shows no charging activity
  • Charger screen shows an error or stays on the start screen after tapping
  • Plug & Charge does not authenticate automatically at a supported station
  • Charge port LED on the EQA does not turn on or blinks red
  • Mercedes me app shows the car as connected but not charging

What to Do

  1. 1

    Remove and reseat the CCS2 connector

    Pull the connector out of the right rear charge port. Inspect it for visible damage or debris. Push it back in firmly until you hear a click. The charge port LED should respond. If the cable feels loose or wobbly, the connector or port may be dirty.

  2. 2

    Authenticate manually if Plug & Charge failed

    Open the charging network's app on your phone and start the session from there. Or tap your RFID card on the charger's reader. Plug & Charge is convenient but not universal. Many networks still require app-based or card-based authentication.

  3. 3

    Check for scheduled charging in MBUX

    Open the charging settings in MBUX. If a departure time or scheduled charging window is active, disable it. At public chargers, you want charging to start immediately. Scheduled charging is designed for home use where off-peak electricity rates matter.

  4. 4

    Lock and unlock the EQA, then try again

    Use the key or Mercedes me app to lock the car, wait 10 seconds, then unlock it. This resets the charge port locking mechanism and the onboard charging controller. Reconnect the cable after unlocking.

  5. 5

    Try a different connector or charger

    If the station has multiple connectors, try another one. If the entire unit seems unresponsive, move to a different charger. Report the faulty charger through the network's app so other drivers know it is down.

Mercedes-Benz EQA Payment Failed at Charging Station

You are at a public charger with your EQA, but payment will not go through. The charger rejects your card, the app shows an error, or Plug & Charge just does not work. Payment problems are one of the most common reasons a charging session fails to start, and they are almost always fixable without leaving the station.

Symptoms

  • Plug & Charge does not authenticate at a supported station
  • Contactless bank card declined at the charger's payment terminal
  • Charging app shows a payment error or insufficient balance
  • RFID card not recognized by the charger's reader
  • Charger starts the session but stops immediately with a billing error

What to Do

  1. 1

    Try Plug & Charge first

    Simply plug the CCS2 connector into the EQA's right rear charge port. If Plug & Charge is activated in your Mercedes me account, the car and charger should authenticate automatically. Wait up to 30 seconds. If nothing happens, move to the next step.

  2. 2

    Use the charging network's app

    Open the app for the specific charging network (the name is usually on the charger). Select the charger by scanning the QR code or entering the station ID. Start the session through the app. Make sure your payment method in the app is current.

  3. 3

    Try contactless payment at the terminal

    Many newer chargers have a contactless payment terminal. Tap your bank card or phone (Apple Pay, Google Pay). If the terminal does not respond, it may be offline. Try a different card if you have one.

  4. 4

    Check your Mercedes me Charge account

    Open the Mercedes me app and go to your Charge settings. Verify that a valid payment method is linked and that Plug & Charge is enabled. If your payment method expired recently, update it. Changes may take a few minutes to sync to the car.

  5. 5

    Use a different RFID card or roaming provider

    If you have multiple charging cards, try another one. Roaming providers like Chargemap, Maingau, or Shell Recharge cover many networks across Europe. Having a second RFID card from a different provider is a reliable backup.

  6. 6

    Move to a different charger or network

    If nothing works at this station, use MBUX navigation or the Mercedes me app to find another charger nearby. A different network may accept your payment method. Filter by the networks you know your cards work with.

Mercedes-Benz EQA Charging Slower Than Expected

You plugged in your EQA at a fast charger expecting close to 100 kW, but the MBUX display shows 30 kW. Or your home wallbox is delivering 3.6 kW instead of 11 kW. Slow charging on the EQA is rarely a defect. It is usually the battery temperature, your state of charge, or a setting in the Mercedes me app you can adjust quickly.

Symptoms

  • DC fast charging speed well below the 100 kW maximum shown on MBUX
  • AC home or destination charging stuck at 3-4 kW instead of 11 kW
  • Charging speed drops sharply after reaching 60-70% state of charge
  • Charging session starts at reasonable speed then slows within minutes
  • MBUX display shows significantly lower power than the charger's rated output

What to Do

  1. 1

    Route to the charger using MBUX navigation

    Enter the charging station as your destination in MBUX. This activates automatic battery preconditioning, which heats the 70.5 kWh battery pack to the ideal temperature range before you arrive. You will see a notification on the display confirming preconditioning is active. The EQA's heat pump makes this efficient even in cold weather.

  2. 2

    Check your state of charge before plugging in

    For the fastest DC charging on the EQA, arrive between 10-20% state of charge. The 100 kW peak is available in this lower range. If you are already above 70%, the slower speed is expected and normal. Plan your stops accordingly on longer trips.

  3. 3

    Verify the charger is not sharing power

    Look at the charging unit. If it has two CCS2 cables and someone is using the other one, you may be splitting the total capacity. Move to an unoccupied charger if available. Single-connector chargers avoid this problem entirely.

  4. 4

    Check charging settings in MBUX or the Mercedes me app

    Open the charging settings in MBUX or the Mercedes me app. Make sure no departure time charging is active (this delays charging to finish just before departure). Confirm the charge current is set to maximum, not reduced. A reduced setting is the most common fix for slow home AC charging.

  5. 5

    Check if Plug & Charge is working correctly

    The EQA supports Plug & Charge at compatible stations. If authentication failed and the charger defaulted to a lower power tier, unplug, wait 30 seconds, and reconnect at the charge port on the right rear side. Check MBUX for any error messages about authentication.

  6. 6

    Try a different charger or restart the session

    If the speed is still low, unplug, lock and unlock the car, then plug in again. If that does not help, try a different charger entirely. Some chargers cannot deliver their rated power due to grid limitations or hardware degradation.

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.
