Why Your Charging Speed May Differ

The MG MG4 supports up to 142 kW DC charging. Gridserve chargers deliver up to 350 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. If your MG MG4 supports battery preconditioning, use the built-in navigation to warm the battery before arriving.
  • If multiple cars share the same Gridserve 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.
