Why Your Charging Speed May Differ

The Mercedes-Benz EQB supports up to 102 kW DC charging. EVBox 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 EQB.
  • Cold weather reduces charging speed. The Mercedes-Benz EQB supports battery preconditioning, which helps.
  • If multiple cars share the same EVBox station, power may be split between stalls.

Mercedes-Benz EQB Charging Problems

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

You have connected your Mercedes-Benz EQB to a public charger, but the session will not start. MBUX shows nothing, the charger sits idle, and you are wondering what is wrong. This is one of the most common complaints at public chargers, and it is usually fixable on the spot.

Symptoms

  • The charger screen stays on 'waiting' or 'connect vehicle' after plugging in
  • MBUX does not show any charging activity
  • The EQB's charge port LED does not illuminate
  • The charger returns an error code after you connect
  • The CCS2 connector does not click into place

What to Do

  1. 1

    Unlock the EQB and open the charge port

    Ensure the car is unlocked. Press the charge port flap to open it. On some EQB models, you can also open it through the Mercedes me app.

  2. 2

    Insert the connector firmly

    Push the CCS2 or Type 2 connector straight into the port until it clicks. The charge port is on the right side of the EQB. A locked connector triggers the charging protocol.

  3. 3

    Authenticate at the charger

    Tap your RFID card on the charger reader, start the session in the network app, or tap your bank card on the contactless terminal. The charger needs authorization before sending power.

  4. 4

    Disable scheduled charging in MBUX

    In MBUX, navigate to EV settings, then charging. If a schedule is set, switch to immediate charging so the EQB does not wait for a timer.

  5. 5

    Disconnect and retry

    Unplug the cable, wait 15 seconds, and reconnect. This forces a fresh handshake between the EQB and the charger.

  6. 6

    Try another charger

    If the charger remains unresponsive, it is likely out of service. Move to a different stall or station and report the faulty unit through the network's app.

Mercedes-Benz EQB Charging Payment Failed: Fix Now

You have connected your Mercedes-Benz EQB to a charger, but the payment will not go through. RFID not recognized, app error, or bank card declined. This is a charger-side issue, not an EQB problem, but it still blocks your session. Here is how to get charging.

Symptoms

  • The charger displays 'authentication failed' or 'payment declined'
  • Your RFID card tap produces no response
  • The charging app returns an error when starting a session
  • Contactless bank card payment is declined
  • The charger asks for payment but no method works

What to Do

  1. 1

    Try an alternative payment method

    Switch from RFID to the charging app, or from the app to a contactless bank card. Having multiple options ensures one failure does not strand you.

  2. 2

    Check your account status

    Open the charging app and verify your payment method, balance, and subscription status. Fix any issues before retrying.

  3. 3

    Verify the charger supports your network

    Look for provider logos on the charger. If yours is not there, you need ad-hoc payment via QR code or a different provider.

  4. 4

    Scan the QR code for ad-hoc payment

    Most European chargers have a QR code that opens a browser-based payment page. Pay with any bank card, no app needed.

  5. 5

    Cancel and restart the session

    If payment seemed to go through but charging did not start, cancel in the app and try again with a fresh authorization.

  6. 6

    Contact the network's support

    The charger should display a phone number. The operator can sometimes authorize sessions remotely or troubleshoot payment issues.

Mercedes-Benz EQB 350+ Charging Slow: How to Fix It

Your Mercedes-Benz EQB 350+ supports up to 102kW DC fast charging, which is moderate for its class. If the MBUX display is showing far less than that, every charging stop takes longer than it should. Here is what affects the EQB's charging speed and how to improve it.

Symptoms

  • DC charging power shown on MBUX is well below 102kW
  • Charging the 70.5kWh battery takes significantly longer than expected
  • Speed drops noticeably above 70% state of charge
  • AC charging is stuck below 11kW at a faster station
  • MBUX displays a battery temperature warning or conditioning indicator

What to Do

  1. 1

    Check charging power in MBUX

    Open the charging status screen on MBUX. It displays current kW, battery temperature, and estimated completion time. This tells you whether the car or charger is limiting speed.

  2. 2

    Precondition the battery before arriving

    Enter the charging station as a destination in MBUX navigation. The EQB will precondition the battery to optimal temperature while you drive. This is the single most effective step in cold weather.

  3. 3

    Find a charger rated at 100kW or more

    Use the Mercedes me app or a charger map to locate high-power stations. Ionity, Fastned, and some Shell Recharge stations offer 100kW+ chargers.

  4. 4

    Avoid power-sharing stalls

    Choose a charger pair where the adjacent stall is empty. This gives the EQB the full output of the charger.

  5. 5

    Charge between 10% and 80%

    Plan stops to arrive between 10% and 15% and leave at 80%. This keeps you in the EQB's fastest charging window.

  6. 6

    Check for software updates

    Mercedes releases over-the-air updates that can improve charging behavior. Check MBUX under Settings for available updates.

Common EVBox Issues

EVBox app vs third-party operator confusion

You see an EVBox-branded charger and download the EVBox app, but the session will not start because the station is operated by a different company. Many EVBox chargers are hardware only, with a separate operator managing access and billing.

Symptoms

  • EVBox app does not show the station or cannot start a session
  • You created an EVBox account but the charger asks for a different app or RFID card
  • Charger has EVBox branding but the screen shows a different company name
  • QR code on the charger leads to a different operator's website or app

How to Fix It

  1. 1

    Check the operator name on the charger screen or signage

    Look at the charger display when it is idle. The operator name is usually shown on the welcome screen. Common operators using EVBox hardware include municipalities, parking companies, and energy providers.

  2. 2

    Scan the QR code on the charger

    The QR code leads to the operator's platform, not necessarily EVBox. Scan it to find out which app or website you need.

  3. 3

    Try a roaming RFID card

    If you have an RFID card from Shell Recharge, Chargemap, Plugsurfing, or another roaming provider, try tapping it. Many EVBox chargers accept roaming cards regardless of who operates them.

  4. 4

    Search for the station in a multi-network app

    Apps like Chargemap or Shell Recharge aggregate many operators. Search for the charger location and you should see which operator runs it and how to start a session.

  5. 5

    Download the correct operator's app

    Once you know who operates the station, download their app. The EVBox app only works for chargers that EVBox operates directly.

CHAdeMO connector availability varies

Some EVBox fast chargers have both CCS2 and CHAdeMO connectors, but the CHAdeMO connector may be out of service, removed, or restricted. CHAdeMO is being phased out in Europe and availability is declining.

Symptoms

  • CHAdeMO connector is physically present but does not work
  • Charger screen shows CHAdeMO as 'Unavailable' or 'Out of Order'
  • CHAdeMO connector has been removed and the port is capped
  • App shows CHAdeMO available but the physical connector is missing

How to Fix It

  1. 1

    Check the charger before relying on CHAdeMO

    If your vehicle uses CHAdeMO, visually confirm the connector is present and functional at the station before planning your stop. App data may not reflect recent hardware changes.

  2. 2

    Try the CHAdeMO connector even if the app status is unclear

    Plug in and attempt to start a session. Sometimes the app shows a stale status but the connector works fine.

  3. 3

    Have a CCS2 adapter as a long-term solution

    If your vehicle only has CHAdeMO (common in older Nissan Leafs and some Mitsubishi models), CHAdeMO infrastructure is shrinking across Europe. A CHAdeMO-to-CCS2 adapter may be worth investigating for your specific vehicle.

  4. 4

    Filter for CHAdeMO in your charging app

    When planning a route, filter specifically for stations with verified CHAdeMO connectors. User reviews and recent check-ins are more reliable than operator listings for CHAdeMO availability.

RFID card registration process unclear

To use an RFID card at EVBox-operated stations, you may need to register the card through the EVBox platform first. The registration process is not always obvious.

Symptoms

  • New RFID card does not work at the charger even after ordering it from EVBox
  • Card works at other networks but not at EVBox-operated stations
  • You received a card but there are no activation instructions
  • Online portal asks for a card number format you do not recognize

How to Fix It

  1. 1

    Check the activation email

    When you order an RFID card from EVBox, they send an activation email. Check your inbox and spam folder. The email contains a link to activate the card in your EVBox account.

  2. 2

    Add the card in the EVBox app or portal

    Log in to your EVBox account (app or web portal). Navigate to 'My cards' or 'Charge cards' and add the card using the number printed on it. The card does not work until it is linked to your account.

  3. 3

    Wait for activation to propagate

    After registering the card, it may take up to 24 hours for the activation to reach all chargers. If the card does not work immediately after registration, try again the next day.

  4. 4

    Use the app as a backup while the card activates

    You can start sessions through the EVBox app while waiting for your RFID card to activate. Tap 'Start charging' in the app and select the charger.

Charger offline due to firmware update

EVBox periodically pushes firmware updates to their chargers. During an update, the charger is temporarily unavailable. This can happen without warning and usually lasts 10 to 30 minutes.

Symptoms

  • Charger screen shows 'Updating' or 'Maintenance' message
  • Charger was working a few minutes ago but now shows as offline
  • App shows the charger as unavailable with no estimated return time
  • Multiple chargers at the same location are all offline simultaneously

How to Fix It

  1. 1

    Wait 10 to 15 minutes

    Firmware updates on EVBox chargers usually complete within 10 to 30 minutes. If the charger shows an update message, it will likely come back online shortly.

  2. 2

    Try another charger at the same location

    Firmware updates sometimes roll out one unit at a time. If there are multiple chargers, others may still be operational.

  3. 3

    Check the app for status updates

    The operator's app or the EVBox app may show whether the outage is a scheduled update or an unexpected fault. Scheduled updates usually have an estimated completion time.

  4. 4

    Move to an alternative station if you cannot wait

    If you need to charge immediately and the update is taking longer than expected, use a multi-network app to find the nearest available charger from any network.

Power sharing between connectors reduces speed

Some EVBox fast chargers share their power output between two connectors. When both are in use, each vehicle receives roughly half the charger's maximum power.

Symptoms

  • Charging speed drops by half when a second car plugs into the same unit
  • Dashboard shows 75 kW at a charger rated for 150 kW
  • Speed suddenly increases when the car on the other connector finishes
  • One side of the charger consistently delivers more power than the other

How to Fix It

  1. 1

    Check if both connectors are on the same unit

    EVBox dual-connector chargers share one power module. If both CCS2 cables come from the same physical cabinet, they share power. Two separate cabinets are two independent chargers.

  2. 2

    Choose an unoccupied charger unit if available

    If multiple charger units are available, pick one where the other connector is not in use. You will get the full rated power to yourself.

  3. 3

    Understand how power sharing works

    Power sharing is dynamic. The charger allocates power based on what each vehicle can accept. If the other vehicle is at 80% and barely drawing power, you may get most of the charger's output even while sharing.

  4. 4

    Wait for the other car to finish

    If your speed is reduced by sharing, it will increase when the other vehicle finishes. Check your dashboard periodically. The speed change happens automatically without any action from you.

  5. 5

    Check your vehicle's own limits first

    Before assuming power sharing is the issue, verify that your car is not limiting the speed due to battery temperature, state of charge above 80%, or its own maximum DC charging rate.

EVBox App Tips

  • The EVBox app only works for chargers operated by EVBox directly. Most EVBox-branded chargers are operated by other companies. Always check the operator name on the charger first.
  • If you see an EVBox charger, scan the QR code before downloading any app. It will tell you which operator's platform you actually need.
  • For EVBox-operated stations, the app shows real-time connector status, power output, and session cost. Use it to monitor your session remotely.
  • Register your RFID card in the EVBox app or web portal before trying to use it. Unregistered cards are not recognized by the chargers.

Payment Tips

  • RFID cards from major roaming networks work at most EVBox chargers regardless of operator. Shell Recharge, Chargemap, and Plugsurfing have good coverage.
  • If your RFID card fails, check which company operates the station. The EVBox app may not help if someone else runs the charger.
  • EVBox-operated stations show pricing on the charger screen before you start. Rates vary by location and time of day at some stations.
  • For EVBox-operated chargers, you can link a payment method in the EVBox app for seamless billing. Invoices are available in your account.
