Why Your Charging Speed May Differ

The Mercedes-Benz EQA supports up to 102 kW DC charging. Allego 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 Allego 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 Allego Issues

Allego app not starting a session

You open the Allego app, select the charger, tap 'Start,' and nothing happens. The app may spin, show an error, or claim the charger is offline even though the screen in front of you says otherwise.

Symptoms

  • Allego app shows a loading spinner that never finishes
  • 'Charger unavailable' in the app but the physical charger looks operational
  • App crashes when tapping 'Start Charging'
  • Session appears to start in the app but the charger does not begin delivering power

How to Fix It

  1. 1

    Make sure you selected the correct charger and connector

    Allego stations often have multiple charging points. Each one has its own ID, usually printed on a sticker near the connector. Match this ID to the one shown in the Allego app. Selecting the wrong point is the most common reason a session will not start.

  2. 2

    Plug in the cable before starting the session in the app

    Most Allego chargers require the cable to be connected to your car first. The charger needs to detect a vehicle before it will accept a start command from the app.

  3. 3

    Close and reopen the Allego app

    Force-close the app completely (swipe it away from your recent apps), wait a few seconds, and reopen it. Try starting the session again.

  4. 4

    Scan the QR code on the charger instead

    Most Allego chargers have a QR code that opens a web-based payment page. This works independently of the Allego app and lets you pay with a credit card without needing an account.

  5. 5

    Use an RFID card from a roaming provider

    If you have an RFID card from a provider like Shell Recharge, Plugsurfing, or Chargemap, hold it against the reader on the charger. This bypasses the Allego app entirely.

Charger not appearing in the Allego app

You are standing in front of a physical Allego charger, but it does not show up on the Allego app map. The charger is clearly operational and other drivers are using it.

Symptoms

  • Charger location is missing from the the Allego app map entirely
  • App shows the location but with zero available connectors
  • Charger appears under a different brand name in other apps but not in the Allego app
  • Newly installed charger not yet listed

How to Fix It

  1. 1

    Check if the charger is operated under a different brand

    Allego operates under various local labels in different countries. The charger might be listed under the local brand name rather than 'Allego' in some apps. Look for a sticker or sign on the charger that shows the operator name and EVSE ID.

  2. 2

    Search by charger ID instead of location

    In the Allego app, try the search function and enter the charger's EVSE ID (printed on the unit, usually starting with a country code like DE*, NL*, or FR*). This can find chargers that are not correctly placed on the map.

  3. 3

    Use the QR code on the charger

    Scan the QR code on the charger with your phone camera. This will open a direct link to start a session, even if the charger is missing from the app map.

  4. 4

    Try a different charging app

    Allego chargers are accessible through many roaming providers. Open an app like Chargemap, Shell Recharge, or Plugsurfing and search for the same location. You may be able to start the session there.

Third-party RFID card not accepted

You hold your RFID card from another provider against the reader and the charger beeps but rejects it, or nothing happens at all.

Symptoms

  • Charger beeps once but displays 'Card not recognized'
  • No reaction when holding the RFID card to the reader
  • Card works at other networks but not at this Allego charger
  • 'Authorization failed' message on the charger screen

How to Fix It

  1. 1

    Check if your roaming provider covers Allego

    Not all RFID providers have roaming agreements with Allego. Check your provider's app or website to confirm Allego is listed in their coverage. Some providers cover only certain Allego locations.

  2. 2

    Hold the card flat and steady for 3 seconds

    Do not wave or tap the card. Place it flat against the reader and hold it still. Allego readers can be slower to respond than some other networks.

  3. 3

    Try a different position on the reader

    The RFID antenna inside the reader has a specific sweet spot. Move your card slowly across the reader surface until you get a response. On some Allego chargers, the reader is on the right side panel rather than the front.

  4. 4

    Check your RFID card is activated

    Some providers require you to activate your RFID card in their app before first use. Open your provider's app and look for card activation or card management settings.

  5. 5

    Fall back to QR code or Allego app

    If your RFID card will not work, scan the QR code on the charger for direct credit card payment, or download the Allego app and register to start the session digitally.

Long delay before charging actually starts

You have authenticated and the charger says it is starting, but 30 seconds, sometimes over a minute, passes before any power flows to your car.

Symptoms

  • Charger screen says 'Starting' or 'Initializing' for over 30 seconds
  • Car shows 'Waiting for charger' or 'Preparing'
  • Power reading stays at 0 kW for a full minute after authentication
  • You wonder if you should unplug and try again

How to Fix It

  1. 1

    Wait at least 90 seconds before taking action

    Allego high-power chargers perform a communication handshake with your car before delivering power. This includes safety checks, voltage negotiation, and isolation testing. A 30-60 second delay is normal, especially on 350 kW units.

  2. 2

    Do not unplug during the initialization phase

    Unplugging and re-plugging resets the entire handshake process. If the charger screen shows any progress (status messages, icons changing), let it complete.

  3. 3

    Check if your car's charge port is locked

    The connector should be locked into your car's charge port during initialization. If you can wiggle the connector freely, it may not be fully inserted. Push it in firmly and listen for the lock click.

  4. 4

    If nothing happens after 2 minutes, restart the session

    Unplug the connector, wait 10 seconds, plug it back in, and authenticate again. If the delay repeats, try a different connector or charger at the same station.

Charging power much lower than advertised

The charger is rated for 350 kW, but your car is only pulling 50 kW or less. The session is working, just far slower than expected.

Symptoms

  • Car or charger display shows 40-80 kW on a 350 kW charger
  • Estimated charge time is much longer than expected
  • Power started high but dropped dramatically within minutes
  • Other cars at the same station seem to charge faster

How to Fix It

  1. 1

    Check your battery level

    DC charging slows significantly above 60-70% state of charge on most cars. If your battery is already at 65% or higher, the reduced speed is your car protecting its battery, not a charger problem.

  2. 2

    Check your car's maximum DC charging rate

    A 350 kW charger can deliver up to 350 kW, but your car decides how much to accept. Many EVs top out at 100-150 kW. Check your car's specifications for its maximum DC charging speed.

  3. 3

    Consider battery temperature

    Cold batteries charge slowly. If you have been parked for hours in cold weather without preconditioning, your car may limit charging to 30-60 kW until the battery warms up. Some cars let you precondition the battery by setting the charger as your navigation destination.

  4. 4

    Check if the station is power-sharing

    Some Allego stations share power between multiple chargers. If three cars are charging simultaneously, each one may get less than the maximum. This is normal at shared-power sites.

  5. 5

    Try a different connector at the same station

    Occasionally one connector delivers less power due to a hardware limitation. If you are getting unusually low power even at a low battery level, unplug and try the next unit.

Allego App Tips

  • The Allego app shows real-time availability and power output for each connector. Check it before driving to a station to avoid arriving at a fully occupied site.
  • You can save favorite stations in the Allego app for quick access. Useful if you have a regular route and know which Allego stations work well.
  • the Allego app shows pricing before you start. Review the per-kWh rate and any session fees before tapping 'Start,' especially at roaming locations where prices vary.
  • If the Allego app is acting up, the QR code on the charger is your fastest backup. It opens a web page that works in any browser, no app required.
  • Allego chargers in different countries may appear under local brand names. If you cannot find a charger in the Allego app, search by the EVSE ID printed on the unit.

Payment Tips

  • Paying directly via QR code or the Allego app often gives you a better rate than paying through a roaming provider. Roaming adds a markup.
  • Allego accepts Visa, Mastercard, and most European debit cards through the QR code payment flow. No account needed.
  • If you use a roaming RFID card, your roaming provider sets the price, not Allego. The same charger can cost different amounts depending on which card you use.
  • Check whether your roaming provider charges a flat session fee on top of the per-kWh rate. Some add 1-2 EUR per session at Allego stations.
  • Check the Allego app for current pricing options and any available subscription plans. Sessions can be paid through the Allego app, QR code, or your roaming provider.
