Mercedes-Benz EQC Charging at Fastned

Mercedes-Benz EQC Charger Won't Start: Quick Fixes

You have plugged your Mercedes-Benz EQC into a public charger, but nothing is happening. No charging animation on MBUX, no power flowing, just a dead charger screen. This is one of the most common frustrations at public stations, and the fix is usually simple.

Symptoms

• The charger display shows 'connect vehicle' even though the cable is connected
• MBUX does not indicate any charging activity
• The EQC's charge port LED stays off or blinks without starting
• The charger shows an error code after plugging in
• The CCS2 plug does not click securely into the port

What to Do

1. 1

   Unlock the EQC

   Make sure the car is unlocked. The charge port only opens and accepts a connector when the EQC is unlocked.

2. 2

   Insert the connector firmly

   Push the CCS2 or Type 2 connector straight into the port until it clicks. The EQC's charge port is on the right rear side. A locked connector initiates the communication protocol.

3. 3

   Start the session at the charger

   Tap your RFID card, open the network app, or use contactless payment. The charger needs this step before it will send power to the EQC.

4. 4

   Check MBUX for scheduling conflicts

   In MBUX, navigate to EV settings and check for charging schedules. If one is active, switch to immediate charging.

5. 5

   Unplug and reconnect

   Remove the cable, wait 15 seconds, and plug it back in. This resets the handshake between the EQC and the charger.

6. 6

   Move to a different charger

   If nothing works, the charger is likely faulty. Try a different stall or station and report the broken charger through the network app.

Mercedes-Benz EQC Charging Payment Rejected: Fixes

Your Mercedes-Benz EQC is plugged in and ready, but the charger will not accept your payment. RFID card ignored, app throwing errors, or bank card declined. This is not an EQC issue, but it still stops you from charging. Here is what to do.

Symptoms

• The charger displays 'authentication failed' or 'payment error'
• RFID card tap gets no response from the charger
• The charging app fails with a payment error when starting a session
• Contactless bank card is declined at the terminal
• The charger asks for payment but you have no compatible method

What to Do

1. 1

   Try a different payment method

   Switch from RFID to the app, or from the app to a contactless bank card. Most chargers support multiple payment options.

2. 2

   Verify your account status

   Open the charging app and check your payment method, balance, and subscription. Fix any expired cards or low balances.

3. 3

   Check which networks are accepted

   Look at the charger for logos of supported providers. If your provider is not there, look for a QR code for ad-hoc payment.

4. 4

   Use the QR code for direct payment

   Scan the QR code on the charger with your phone. It opens a web-based payment page where you can use any bank card without an app.

5. 5

   Cancel and retry

   If payment appeared to process but charging did not start, cancel the session in the app and authorize a new one.

6. 6

   Call the network support number

   Most chargers display a support phone number. The operator can sometimes start sessions remotely or identify payment issues.

Mercedes-Benz EQC Charging Slow: No Preconditioning

Your Mercedes-Benz EQC 400 4MATIC supports up to 112kW DC fast charging, but you are seeing much lower numbers on the MBUX display. Unlike newer Mercedes EVs, the EQC does not have battery preconditioning, which makes cold weather charging particularly slow. Here is what is happening and what you can do about it.

Symptoms

• DC charging power shown on MBUX is well below 112kW
• The 80kWh battery takes much longer to charge than expected
• Charging speed drops significantly above 70% state of charge
• AC charging is stuck at or below 11kW
• Cold weather charging is noticeably slower than in summer

What to Do

1. 1

   Check charging power in MBUX

   Open the charging status screen on MBUX. It shows current kW, battery temperature, and estimated time. This helps identify whether the car or charger is limiting speed.

2. 2

   Warm the battery through driving

   Since the EQC lacks automatic preconditioning, the best approach is to drive at motorway speeds for at least 20 to 30 minutes before arriving at a fast charger. This passively warms the battery and improves charging speed.

3. 3

   Choose chargers rated at 120kW or more

   Use the Mercedes me app or a charger map to find high-power stations. To reach the EQC's 112kW peak, the charger needs to be rated at 120kW or higher.

4. 4

   Avoid shared stalls

   At stations with paired CCS2 connectors, pick a pair where the other stall is empty. This gives the EQC the full charger output.

5. 5

   Charge between 10% and 80%

   Plan stops to arrive between 10% and 15% and leave at 80%. The EQC charges fastest in this range.

6. 6

   Avoid charging from a cold start in winter

   If possible, do not stop for a fast charge immediately after the car has been parked overnight in freezing temperatures. Drive for a while first to let the battery warm up naturally.

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.
