Why Your Charging Speed May Differ

The Mercedes-Benz EQA supports up to 102 kW DC charging. EnergyVision chargers deliver up to 150 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 EnergyVision 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 EnergyVision Issues

Session won't start or authentication fails

You try to start a session through the EnergyVision app or charge card, but the charger does not respond or shows an error.

Symptoms

  • The app will not connect to the charger or keeps loading
  • Your RFID charge card is not recognized
  • You have no mobile data at the station location
  • The charger screen shows an error after authentication

How to Fix It

  1. 1

    Install and set up the EnergyVision app before you travel

    Create your account and add a payment method at home, on a reliable internet connection. Do not try to set up the app for the first time at a station with weak signal.

  2. 2

    Try a different authentication method

    If the app is not working, try your EnergyVision charge card (RFID) instead, or vice versa. Having both options available increases your chances of starting a session.

  3. 3

    Try switching between Wi-Fi and mobile data

    Some apps struggle with certain network configurations. Toggle your phone's Wi-Fi off (or on, if a nearby network is available) and try again. Sometimes a network switch forces the app to reconnect.

  4. 4

    Restart the app and your phone

    Close the app completely (not just minimize), reopen it, and try again. If that fails, restart your phone.

  5. 5

    Have a backup charging app ready

    Always carry a second charging app from a larger network. If EnergyVision is not working, you need to find an alternative charger from another operator.

Limited station coverage

EnergyVision has fewer stations than major networks. This means longer distances between chargers and fewer alternatives if a station is broken or occupied.

Symptoms

  • The app shows very few stations along your route
  • The nearest EnergyVision station is 50 km or more away
  • You arrived at the only EnergyVision station in the area and it is out of order
  • There is no second EnergyVision charger to fall back to

How to Fix It

  1. 1

    Never rely on EnergyVision as your only charging option

    Plan your route with at least one alternative network at each stop. EnergyVision stations are a bonus when they work, but their spacing means you cannot depend on them exclusively.

  2. 2

    Install apps for larger networks in the same region

    Identify which major networks operate near EnergyVision stations (Ionity, Shell Recharge, Fastned, or regional operators). Install their apps so you can switch quickly if needed.

  3. 3

    Use a multi-network route planner

    A Better Routeplanner (ABRP) or similar tools show chargers from all operators. Plan your stops based on all available chargers, not just one network. EnergyVision stations will appear where they exist.

  4. 4

    Charge a little extra at reliable stations before entering sparse areas

    If your next stop is an EnergyVision station in an area with few alternatives, charge to 90% at the station before it instead of the usual 80%. The extra buffer gives you range to reach a different charger if the EnergyVision station is down.

Different charger hardware at different locations

EnergyVision uses charger units from different manufacturers at different stations. This means the physical interface, cable handling, and screen layout vary from one station to the next.

Symptoms

  • The charger at this station looks completely different from the last EnergyVision station you used
  • The connector release mechanism works differently than expected
  • The charger screen layout does not match what you see in the app
  • Error codes or messages are in a different format than at other EnergyVision stations

How to Fix It

  1. 1

    Check the charger unit for basic instructions

    Most charger manufacturers print basic instructions on the unit itself: where to plug in, how to release the connector, and where the emergency stop button is. Take a moment to read these, as they vary between manufacturers.

  2. 2

    Start the session through the app, not the charger screen

    Regardless of the charger hardware, the EnergyVision app is the consistent interface. Start and stop sessions through the app. The charger screen is secondary.

  3. 3

    If the connector release is different, check for a button or lever

    Some charger manufacturers use a push-button release, others use a lever, and some release automatically when the session ends. Look at the connector handle and the charger unit for release instructions.

  4. 4

    Report hardware-specific problems in the app

    If a charger unit from a specific manufacturer is repeatedly problematic, report it through the EnergyVision app. Include details about what happened so the support team can pass it to the hardware vendor.

App not available in all app stores or regions

Smaller networks sometimes have app availability issues. The EnergyVision app may not appear in your app store if your account is set to a country where EnergyVision does not operate.

Symptoms

  • You search for 'EnergyVision' in your app store and no results appear
  • The app is listed but marked as 'not available in your country'
  • You found the app but it will not install on your phone model
  • A link to the app store listing leads to a 'not found' page

How to Fix It

  1. 1

    Check the EnergyVision website for the correct app name and link

    The app may be listed under a slightly different name in some app stores. Visit the EnergyVision website on your phone and look for a direct download link that opens the correct store listing.

  2. 2

    Check your app store country setting

    If your App Store or Google Play account is set to a country where EnergyVision does not operate, the app may be hidden. You can check this in your store account settings.

  3. 3

    Check if a roaming app supports EnergyVision stations

    Some roaming platforms include smaller networks. Search for the station location in a roaming app (like Chargemap or Octopus Electroverse) to see if you can start a session through a third-party app instead.

  4. 4

    Contact EnergyVision support for alternative access

    If you cannot install the app, contact EnergyVision through their website. They may have a web-based session starter or be able to suggest a roaming provider that includes their stations.

Slower support response times

As a smaller operator, EnergyVision may have fewer support staff than major networks. Response times for non-urgent issues can be longer, and phone support may have limited hours.

Symptoms

  • You reported an issue through the app and have not heard back
  • The support phone number goes to voicemail or has limited hours
  • You need help at a station but cannot reach anyone
  • Your email to support has not been answered after several days

How to Fix It

  1. 1

    Use the app's support feature for the fastest response

    In-app support requests typically get prioritized over emails sent to a general address. If the app has a help, chat, or report issue option, use that first.

  2. 2

    Include all relevant details in your first message

    To avoid back-and-forth that stretches across days, include: station location, charger ID (printed on the unit), time of the issue, what happened, and any error messages. Screenshots help.

  3. 3

    Do not wait at a broken charger for support to respond

    If a charger is not working and support is not answering, move on. Report the issue through the app and drive to the next available charger from any network. Waiting at a broken charger hoping for a callback is not practical.

  4. 4

    For billing disputes, document everything

    Screenshot your charging session details (from the app), note the charger ID and time, and save any error messages. If you were charged for a failed session, this documentation helps you get a refund when support responds.

EnergyVision App Tips

  • Set up the EnergyVision app at home before your first session. App-only networks require everything to work on your phone, so test the login and payment setup on a good connection.
  • Check charger availability in the app before driving to a station. With fewer stations in the network, an occupied or broken charger means a longer detour to an alternative.
  • Keep the app updated. Smaller networks sometimes push updates that fix critical bugs or add new stations. An outdated app may not show the latest locations or may have connection issues.
  • Save the EnergyVision support phone number in your contacts. If the app is not loading, you will not be able to find it in the app when you need it most.

Payment Tips

  • EnergyVision supports payment through their app and charge cards (RFID). Set up your preferred method before you need to charge.
  • Add your payment card to the app before you need to charge. Account setup at a station with weak signal is a recipe for frustration.
  • Check if a roaming platform includes EnergyVision stations. Having a second way to pay through a roaming app is good insurance for app-only networks.
  • EnergyVision pricing is per kWh. The rate is shown in the app before you start. Review it each time, as smaller networks occasionally adjust pricing.
