Why Your Charging Speed May Differ

The Mercedes-Benz EQA supports up to 102 kW DC charging. Fastned chargers deliver up to 400 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 Fastned 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 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.
