Why Your Charging Speed May Differ

The Mercedes-Benz EQA supports up to 102 kW DC charging. REWE Charging chargers deliver up to 300 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 REWE Charging 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 REWE Charging Issues

Charger occupied by non-charging vehicles

You arrive at the REWE charger and a car is parked in the charging spot without being plugged in. This is common at supermarket locations where shoppers treat EV spots as regular parking.

Symptoms

  • Charging spot is occupied by a car with no cable connected
  • ICE vehicle parked in the EV charging bay
  • Car is plugged in but session has clearly ended and the driver is inside shopping
  • All charging spots taken despite the app showing the charger as available

How to Fix It

  1. 1

    Check if the other car is actively charging

    Look at the charger display or connector. If the session has ended and the car is just parked, REWE cannot remotely move it. The app status reflects the charger, not the parking spot.

  2. 2

    Ask at the REWE customer service desk

    REWE staff can sometimes make a store announcement asking the vehicle owner to move. This works more often than you would expect.

  3. 3

    Wait briefly or shop first

    At supermarket chargers, turnover is high. Most shoppers leave within 30 to 45 minutes. Do your shopping and check again.

  4. 4

    Check for additional REWE locations nearby

    Many German cities have multiple REWE stores with chargers within a short drive. Check the app for the next closest option.

Contactless card reader not responding

You tap your debit or credit card on the reader but nothing happens. The reader does not beep, does not show a light, or shows an error briefly before resetting.

Symptoms

  • Card reader shows no response when you tap
  • Reader beeps but the screen shows an error
  • Card works at the REWE checkout inside but not at the charger
  • Contactless symbol is visible on the reader but it seems inactive

How to Fix It

  1. 1

    Hold your card flat against the reader for 3 to 5 seconds

    Some REWE charger readers are slower than store payment terminals. Hold the card still and wait for the full processing time.

  2. 2

    Remove your phone and other cards from the area

    If you hold your wallet with multiple contactless cards near the reader, it may detect interference and reject the transaction.

  3. 3

    Try the charging app instead

    If contactless is not working, start the session through the REWE charging partner app. This bypasses the physical card reader entirely.

  4. 4

    Check if the reader is physically damaged

    Supermarket chargers are exposed to shopping carts, weather, and heavy foot traffic. If the reader looks cracked or the screen is damaged, report it to REWE staff inside and try another stall if available.

Session ends due to maximum stay time limit

Your charging session stops before the battery is full because REWE enforces a maximum parking time at the charging spot. This exists to keep spots available for other shoppers.

Symptoms

  • Charging stops after 60 to 90 minutes even though the battery is not full
  • App notification says session ended due to time limit
  • You return from shopping to find the charger disconnected
  • Charger screen shows session completed despite low battery level

How to Fix It

  1. 1

    Check the posted time limit before you start

    REWE typically allows 60 to 120 minutes depending on the location. Look for signage near the charger or check the app for time restrictions at that specific store.

  2. 2

    Plan your charge around your shopping time

    At up to 300 kW, most EVs can gain 150 to 250 km of range in 30 to 45 minutes. A normal grocery run is usually enough time for a meaningful charge.

  3. 3

    Move your car if you need more time

    If you need a longer session, move your car to a regular parking spot after the time limit and start a new session if the charger is free when you return.

  4. 4

    Use REWE chargers for top-ups, not full charges

    Supermarket chargers work best for adding range while you shop, not for charging from 10% to 100%. If you need a full charge, plan for a dedicated fast charging station.

Poor mobile signal in underground or garage parking

Some REWE stores have chargers in basement or covered parking areas where mobile signal is weak. This can prevent the app from starting a session or processing contactless payments.

Symptoms

  • App shows 'No connection' or spins without loading
  • Contactless payment times out during processing
  • You cannot scan the QR code on the charger because the page will not load
  • Session starts but the app loses connection and cannot show charging status

How to Fix It

  1. 1

    Connect to REWE store WiFi if available

    Many REWE stores offer free WiFi that may reach the parking area. Check for a REWE network in your phone's WiFi settings.

  2. 2

    Walk closer to the garage entrance to start the session

    If you need the app to start the session, walk toward the exit where signal is stronger, start the session remotely, then return to your car.

  3. 3

    Use contactless payment instead of the app

    Contactless card payments are processed through the charger's built-in connection, not your phone. If the card reader works, you do not need mobile signal.

  4. 4

    Pre-load the app before entering the garage

    Open the app and navigate to the station page while you still have signal. Some apps cache enough data to start a session even with intermittent connectivity.

Charger unavailable outside store hours

You arrive at a REWE charger outside store opening hours and the charger is inaccessible or powered down. Some locations gate their parking areas or shut down chargers when the store closes.

Symptoms

  • Parking area gate is locked and you cannot reach the charger
  • Charger screen is dark and does not respond
  • App shows the charger as available but the physical location is closed
  • Barrier arm blocks entry to the parking lot after closing time

How to Fix It

  1. 1

    Check store hours before planning a charge

    REWE stores in Germany typically close between 20:00 and 22:00 on weekdays and earlier on Saturdays. Most are closed on Sundays. If the charger is behind a gate, you cannot access it outside these hours.

  2. 2

    Verify 24/7 access in the app

    Some REWE charging locations offer 24/7 access even when the store is closed. Check the station details in the app. If it does not mention 24-hour access, assume it follows store hours.

  3. 3

    Leave the parking area before the store closes

    If you are charging and the store is about to close, make sure you can exit the parking area. Some locations lock the barrier after closing, which could trap your car overnight.

  4. 4

    Find an alternative nearby charger

    Use a multi-network app like Chargemap or the EVcourse charger finder to locate a 24/7 charger nearby. Dedicated charging stations along main roads usually operate around the clock.

REWE Charging App Tips

  • REWE chargers are often operated by a charging partner (such as Allego or EWE Go). Check which app you actually need by scanning the QR code on the charger or looking at the operator logo.
  • Pre-load the station page in the app before entering a parking garage. Underground signal issues are common at REWE locations.
  • Enable session end notifications so you can move your car promptly and avoid blocking the spot for other shoppers.
  • Check the app for time limits at each specific REWE location. They vary by store and are not always posted clearly on signage.
  • If the app is not working, look for a phone number on the charger itself. The charging operator (not REWE) handles technical support.

Payment Tips

  • Contactless debit and credit cards usually work at REWE chargers without needing an app or account. Look for the contactless symbol on the card reader.
  • Pre-authorization holds can be up to 100 EUR depending on the operator. The actual charge amount replaces the hold within a few business days.
  • Some REWE charging operators offer roaming through networks like Hubject or Gireve. Your existing charging card or app from another network may work here.
  • Keep your payment card handy, not buried in your shopping bags. If the session stops unexpectedly, you may need to re-authenticate quickly.
