Why Your Charging Speed May Differ

The MG MG4 supports up to 142 kW DC charging. GreenWay chargers deliver up to 150 kW. Your car's maximum intake is the limiting factor here, capping speed at 142 kW even on a faster charger.

  • Charging slows down above 80% state of charge on most EVs, including the MG MG4.
  • Cold weather reduces charging speed. The MG MG4 supports battery preconditioning, which helps.
  • If multiple cars share the same GreenWay station, power may be split between stalls.

MG MG4 Charging Problems

MG MG4 Charger Won't Start? How to Fix It Now

You have plugged in your MG MG4 but nothing is happening. The charger light is blinking, the car is not responding, or you are getting an error message. This is frustrating, but most failed charging sessions have a simple fix. Let's walk through the common causes.

Symptoms

  • Charger display shows an error code or red indicator
  • CCS2 connector clicks in but charging does not begin
  • Car dashboard shows no charging activity after plugging in
  • Charger screen asks for authentication but does not accept your card or app
  • Charging port light on the MG4 flashes or stays amber

What to Do

  1. 1

    Check the charger screen for error messages

    Read any error codes or messages on the charger display. Common messages include 'authentication required,' 'connector error,' or 'out of service.' This tells you whether the problem is the charger or the car.

  2. 2

    Unplug and replug the connector

    Remove the CCS2 or Type 2 connector completely, wait 10 seconds, and plug it back in firmly. Make sure you hear the click and the MG4's charge port light responds.

  3. 3

    Authenticate again

    Re-tap your RFID card, restart the session in the app, or try contactless payment. Some chargers require you to authenticate before plugging in, others after. Try both sequences.

  4. 4

    Disable scheduled charging

    On the MG4's infotainment screen, go to vehicle settings and check if scheduled charging is enabled. Turn it off temporarily to allow immediate charging.

  5. 5

    Lock and unlock the car

    Use the MG4's key fob or the MG iSMART app to lock and then unlock the car. This can reset the charge port communication and clear temporary errors.

  6. 6

    Try a different charger or stall

    If nothing works on this stall, try another one at the same station. If the entire station fails, the problem is likely the charger infrastructure, not your MG4.

MG MG4 Charging Payment Failed? Fix It Quickly

You are at a charger with your MG MG4 and the payment is not going through. Your card gets rejected, the app throws an error, or you cannot figure out how to pay at all. Payment issues are one of the most common reasons a charging session fails to start. Here is how to sort it out.

Symptoms

  • RFID card tap does not register on the charger
  • Charging app shows a payment error or insufficient funds
  • Contactless bank card is declined at the charger terminal
  • Charger asks for payment but you cannot find a method that works
  • Session starts but stops immediately due to payment authorization failure

What to Do

  1. 1

    Check which payment methods the charger accepts

    Look at the charger for logos showing accepted payment types: RFID, app, contactless card, QR code. Many chargers display the logos of compatible networks near the screen or card reader.

  2. 2

    Try the network's app

    Scan the QR code on the charger or search for the network's app in your phone's app store. Many networks let you start a session through their app even without an RFID card.

  3. 3

    Try a different payment method

    If your RFID card fails, try the app. If the app fails, try contactless. If you have a multi-network roaming card (like Plugsurfing or Shell Recharge), try that instead.

  4. 4

    Check your card balance and bank notifications

    Open your banking app to check for declined transactions or pre-authorization holds. Contact your bank if the charger is trying to authorize a large hold that exceeds your available balance.

  5. 5

    Use a roaming service

    If you do not have an account with this specific network, a roaming provider like Plugsurfing, Chargemap, or Shell Recharge may cover this charger. These services work across multiple networks with one card or app.

  6. 6

    Find an alternative charger nearby

    If payment truly will not work, search for another charger nearby. Filter your charging app by your available payment methods to find a compatible station.

MG MG4 Charging Slowly? Causes and Quick Fixes

You plugged in your MG MG4 expecting fast charging, but the kW reading is disappointingly low. This is one of the most common frustrations for MG4 drivers, and it usually has a straightforward explanation. Here is what to check and how to get closer to the 142kW DC maximum your car supports.

Symptoms

  • DC charging power showing well below 142kW on the charger display
  • AC home or destination charging stuck below 11kW
  • Estimated charging time much longer than expected
  • Battery percentage climbing very slowly after 60-70% SOC
  • Charging power drops significantly in cold weather

What to Do

  1. 1

    Check the charger's rated power

    Look at the charger label or app to confirm its maximum output. If it is a 50kW unit, your MG4 cannot charge faster regardless of its 142kW capability.

  2. 2

    Check your battery temperature and SOC

    On the MG4's instrument cluster, check your current state of charge. If you are above 70%, the taper is normal. In cold weather, use the preconditioning feature by setting the charger as your navigation destination.

  3. 3

    Activate preconditioning via navigation

    Set the fast charger as your destination in the MG4's built-in navigation. This triggers battery preconditioning, warming the pack to an optimal temperature before you arrive.

  4. 4

    Try a different CCS2 stall

    If the charger has multiple stalls, power may be shared between them. Try an adjacent stall or wait for other cars to finish. Some charging sites have dedicated high-power stalls.

  5. 5

    Check your AC charging cable

    For AC charging, make sure you are using a cable rated for at least 11kW (3-phase, 16A). A single-phase cable limits you to about 3.6kW regardless of what the charger or car supports.

  6. 6

    Verify no charging limit is set in the car

    In the MG4's settings, check if a charging current limit or maximum SOC limit has been set. A reduced AC charging current setting will cap your speed even on a capable charger.

Common GreenWay Issues

App-only payment with no backup option

GreenWay stations require the GreenWay app to start a session. There are no contactless card readers or RFID pads. If the app fails or your phone dies, you cannot charge.

Symptoms

  • No card reader or RFID pad visible on the charger
  • Charger screen shows a QR code or 'Use app to start' message
  • You arrived without the app installed and cannot begin a session
  • Your phone battery is low and you are worried it will die during setup

How to Fix It

  1. 1

    Download the GreenWay app before your trip

    This is non-negotiable for GreenWay stations. Install the app, create an account, and add a payment method while you have good internet and battery. Do this before you leave, not at the charger.

  2. 2

    Charge your phone before arriving at the station

    Since you need your phone to start and monitor the session, make sure it has enough battery. Use your car's USB port or a power bank on the way.

  3. 3

    Try a roaming app as a backup

    Some GreenWay stations are accessible through roaming providers like Plugsurfing, Shell Recharge, or Chargemap. Check your roaming app's map to see if the specific station is covered before counting on it.

  4. 4

    Scan the QR code on the charger

    If you do not have the app, scan the QR code with your phone camera. It may direct you to the app store or, in some cases, to a web-based session start page.

App requires location services for charger activation

The GreenWay app needs location services turned on to activate a charger. Without it, the app cannot verify that you are at the station and will not let you start a session.

Symptoms

  • App shows 'Enable location services' and will not proceed
  • You can see the charger on the map but cannot start a session
  • The 'Start charging' button is grayed out or unresponsive
  • App shows your location incorrectly, placing you far from the station

How to Fix It

  1. 1

    Enable location services for the GreenWay app

    Go to your phone settings, find the GreenWay app, and set location access to 'While Using' or 'Always.' On iPhone: Settings, Privacy, Location Services, GreenWay. On Android: Settings, Apps, GreenWay, Permissions, Location.

  2. 2

    Make sure GPS is turned on, not just Wi-Fi location

    In some areas, Wi-Fi-based location is inaccurate. Turn on full GPS (high accuracy mode on Android) for a precise position fix at the station.

  3. 3

    Step outside your vehicle briefly

    If GPS signal is weak (underground parking, dense urban area), step a few meters away from your car with your phone. This can help the GPS lock onto your position.

  4. 4

    Try selecting the charger manually

    If the app cannot determine your location, try tapping on the station on the map manually or entering the charger's ID number (printed on the charger unit). Some app versions allow manual selection as a fallback.

Coverage gaps between cities

GreenWay's network is concentrated in and around cities. Between major cities, especially on secondary roads, there can be long stretches with no GreenWay stations.

Symptoms

  • No GreenWay stations shown on the app map for 100+ km stretches
  • The nearest GreenWay station requires a detour off your route
  • You planned a trip assuming GreenWay coverage and ran into a gap
  • Available stations between cities are AC-only (slow), not DC fast charging

How to Fix It

  1. 1

    Plan your route and charging stops before leaving

    Use the GreenWay app or a route planner like ABRP (A Better Route Planner) to map out charging stops. Identify gaps in advance so you are not caught by surprise.

  2. 2

    Have alternative charging networks ready

    Install apps for other networks that operate in the region. In Slovakia and Poland, look for Ionity, Shell Recharge, or Greencharge. In Czech Republic, check CEZ or PRE. Having multiple apps ensures you always have a fallback.

  3. 3

    Charge to a higher level before entering a gap

    If you know there is a 150+ km stretch without fast chargers, charge to 90 or even 95% at the last available station. The slower charging speed above 80% is worth it if the alternative is running out of range.

  4. 4

    Check for AC chargers as emergency backup

    Hotels, shopping centers, and some gas stations in Central Europe have AC chargers (Type 2, 11 to 22 kW). These are slow but can add enough range to reach the next fast charger. Many are accessible through Chargemap or Plugsurfing.

Charger screen errors in local language only

When a GreenWay charger displays an error, the message is often in Slovak, Polish, or Czech with no English translation. Understanding what went wrong is difficult.

Symptoms

  • Error message appears in Slovak, Polish, or Czech
  • You cannot tell if the error is temporary or requires support
  • The charger stopped and you do not know why
  • The error code is visible but the description is in a language you do not read

How to Fix It

  1. 1

    Note the error code, not just the text

    Most error messages include a numeric or alphanumeric code (like E-101 or ERR_04). Write down or photograph the code. This is useful for support and often means the same thing regardless of language.

  2. 2

    Use your phone camera to translate the screen

    Open Google Translate or Apple Translate, switch to camera mode, and point it at the charger screen. This gives a real-time translation of the error message.

  3. 3

    Try unplugging and restarting the session

    Many error messages clear on a retry. Unplug, wait 15 seconds, plug back in, and start a new session through the app. Common errors like 'Communication timeout' resolve themselves.

  4. 4

    Contact GreenWay support with the error code

    If the error persists, contact support through the GreenWay app. Provide the error code and the station ID (printed on the charger). GreenWay support can tell you whether the issue is temporary or requires a technician.

Power limited at older installations

Some older GreenWay stations deliver less than 150 kW. They may be rated at 50 kW or have degraded power output due to aging hardware.

Symptoms

  • Charging speed maxes out at 50 kW on a station advertised as 150 kW
  • The charger label says 150 kW but your vehicle never receives more than 50 kW
  • Speed is significantly lower than what you get at newer GreenWay stations
  • The app shows the station as 150 kW but the charger hardware looks older

How to Fix It

  1. 1

    Check the charger label for the actual rated power

    The charger unit itself has a label showing its maximum output. Older GreenWay units may be rated at 50 kW despite the station listing showing 150 kW (which may refer to a newer unit at the same location).

  2. 2

    Check if the station has multiple charger types

    Some GreenWay stations have both older 50 kW and newer 150 kW chargers. Make sure you are plugged into the newer, higher-power unit. It is usually the larger cabinet.

  3. 3

    Verify your vehicle's battery level and temperature

    Your vehicle limits charging speed when the battery is above 60 to 80% or when the battery is cold. Check your dashboard to confirm the car is requesting more than what the charger delivers.

  4. 4

    Use a different station if speed matters

    If you need faster charging and the station is limited, check the GreenWay app for a newer station nearby. Filter by power level to find 150 kW units specifically.

GreenWay App Tips

  • The GreenWay app is mandatory. Download it, create an account, and add a payment method before you travel to Central or Eastern Europe. There is no backup payment option at the charger.
  • Enable location services for the GreenWay app before arriving at a station. The app will not let you start a session without verifying your location.
  • Plan your route using the GreenWay app map or ABRP (A Better Route Planner). Coverage between cities can be sparse, especially on secondary roads.
  • Keep the GreenWay app updated. Newer versions include better station information, bug fixes, and improved reliability for session starts.
  • If you travel across multiple Central European countries, install apps for other networks too (Ionity, Shell Recharge, CEZ). Relying on a single network in this region is risky.

Payment Tips

  • GreenWay is app-payment only. No contactless card readers, no RFID. The app with a registered payment method is the only way to charge.
  • Add your payment card to the GreenWay app before your trip. Setting up payment at the station on a weak connection is frustrating and unreliable.
  • Check per-kWh pricing in the GreenWay app before starting. Prices vary between AC and DC chargers and between countries.
  • If the GreenWay app is not working, try roaming through Plugsurfing or Shell Recharge. Not all GreenWay stations are covered, but many are.
