MG MG5 Charging at Mer

MG MG5 Charger Won't Start? Step-by-Step Help

You have plugged in your MG MG5 and the charging session refuses to start. The charger might be blinking, showing an error, or doing nothing at all. This is a common problem across all EVs, and the MG5 is no exception. Most causes are easy to diagnose and fix on the spot.

Symptoms

• Charger display shows an error or stays on the start screen
• CCS2 connector plugs in but charging does not initiate
• MG5 charge port light does not turn on or stays amber
• App shows the charger as available but the session does not begin
• AC Type 2 cable locks in but no power flows

What to Do

1. 1

   Read the charger screen

   Check for error messages, authentication prompts, or status indicators. If it says 'waiting for vehicle' the problem is on the car side. If it says 'error' or 'out of service,' the charger is the issue.

2. 2

   Unplug, wait, and replug

   Remove the connector completely, wait 15 seconds, and reinsert it firmly. Listen for the locking click on the MG5's charge port. This resets the communication handshake.

3. 3

   Complete authentication

   Tap your RFID card, open the network app and start the session, or use contactless payment. Some chargers need you to authenticate before plugging in, others after.

4. 4

   Check for scheduled charging

   Go to the MG5's charging settings on the infotainment screen. If a charging schedule is active, disable it to allow immediate charging.

5. 5

   Restart the car's systems

   Turn the MG5 off using the start button, wait 30 seconds, then turn it back on. This can clear temporary software glitches that prevent the charge port from communicating.

6. 6

   Move to another stall or station

   If the charger is at fault, try another stall. If no stalls work, the station may have a site-wide issue. Find an alternative station using your charging app.

MG MG5 Charging Payment Failed? How to Fix It

You are standing at a charger with your MG MG5 and the payment will not work. Card declined, app throwing errors, or no idea how to pay at all. This is one of the most frustrating parts of public charging, and it happens to everyone. Here is how to get past it.

Symptoms

• RFID card not recognized when tapped on the charger
• Charging app shows payment error or transaction declined
• Contactless card payment rejected at the terminal
• Charger starts authentication but then returns an error
• Session begins but ends immediately due to payment failure

What to Do

1. 1

   Identify accepted payment methods

   Look at the charger for payment logos and instructions. Note whether it accepts RFID cards, specific apps, contactless cards, or QR code payments. Each charger may support different methods.

2. 2

   Try the network's own app

   Download the charger network's app, create an account, and add a payment method. Then start the session through the app. This bypasses RFID and contactless issues.

3. 3

   Switch to an alternative payment method

   If your primary RFID card fails, try contactless with your bank card. If that fails, try a roaming provider like Plugsurfing, Shell Recharge, or Chargemap.

4. 4

   Check your bank for blocked transactions

   Open your banking app and look for declined or pending transactions. If the pre-authorization was blocked, call your bank or temporarily increase your card limit.

5. 5

   Try a different stall

   If the card reader on one stall is broken, another stall at the same station may have a working reader. Try the next one before giving up on the location.

6. 6

   Find an alternative station

   Use your charging app to find a nearby station from a network where your payment methods are confirmed to work. Filter by your preferred payment method if the app supports it.

MG MG5 Charging Slowly? Why and How to Fix It

Your MG MG5 is charging slower than you expected. With a maximum DC speed of 87kW, the MG5 is not the fastest charger in its class, but it should still deliver reasonable speeds. If you are seeing numbers well below that, something else is going on. Here is what to check.

Symptoms

• DC charging power showing well below 87kW on the charger display
• AC charging stuck below 11kW on a capable wallbox
• Estimated charging time significantly longer than expected
• Charging speed drops sharply above 50-60% SOC
• Very slow charging in cold weather conditions

What to Do

1. 1

   Check the charger's maximum power output

   Verify the charger is rated above 87kW. If it is a 50kW charger, the MG5 is getting the maximum available. Look at the charger label or check in the network app.

2. 2

   Use preconditioning in cold weather

   Set the fast charger as your destination in the MG5's navigation system. This activates battery preconditioning, which warms the battery before you arrive and improves initial charging speed.

3. 3

   Check your state of charge

   If you are above 60% SOC, the MG5's charging taper is expected. For the fastest session, arrive at the charger between 10-20% SOC and charge to 70-80%.

4. 4

   Try a different stall to avoid power sharing

   If the station shares power between stalls, wait for other cars to finish or move to a stall that is not paired with another active charger. Some stations label which stalls share power.

5. 5

   For AC, verify your cable and charger

   Make sure you are using a 3-phase Type 2 cable on an 11kW or higher AC charger. A single-phase connection limits you to about 3.6kW, which adds many hours to a full charge.

6. 6

   Check car settings for charging limits

   In the MG5's settings, look for any AC current limit or maximum charge level that might be capping your speed.

Station occupancy not updating in the app

The Mer app shows a station as available, but when you arrive, all connectors are occupied or out of service. The real-time status in the app can lag behind by several minutes.

Symptoms

• App shows "Available" but all connectors are in use when you arrive
• App shows a station as occupied but the chargers are visibly free
• Connector status flickers between available and occupied in the app
• Recently freed connectors still show as "In use" in the app for several minutes

How to Fix It

1. 1

   Pull to refresh the station detail in the Mer app

   On the station page, pull down to force a status refresh. The app does not always update automatically, and a manual refresh often shows the correct status.

2. 2

   Close and reopen the app

   Force-close the Mer app and reopen it. This clears any cached station data and pulls a fresh status from the server.

3. 3

   Check a third-party app for a second opinion

   Apps like Plugsurfing, A Better Route Planner, or Google Maps sometimes pull fresher data from Mer's backend. Use one of these to verify availability if the Mer app seems wrong.

4. 4

   Drive to the station if it is nearby

   If the station is less than five minutes away, it is often faster to just go and check. Occupancy can change in the time it takes to troubleshoot the app.

Third-party RFID card rejected

You are trying to authenticate with an RFID card from a roaming provider like Plugsurfing, NewMotion, or Virta, but the Mer charger rejects it. Not all third-party RFID cards are accepted at every Mer station.

Symptoms

• Charger screen shows "Card not recognized" after tapping
• The charger beeps once but nothing happens
• Your RFID card works at other networks but fails at Mer
• The charger prompts you to try again but repeated taps do not help

How to Fix It

1. 1

   Hold the card flat against the reader for three full seconds

   Do not tap and remove quickly. Some Mer readers need a longer hold to register the card. Keep it pressed flat against the RFID symbol.

2. 2

   Check if your roaming provider covers Mer stations

   Open your roaming provider's app and search for this specific Mer station. Some providers have roaming agreements with Mer but not for every station type or region.

3. 3

   Use the Mer app instead

   Download the Mer app if you do not have it. Create an account and add a payment method. You can start the session through the app even if your RFID card does not work.

4. 4

   Try contactless bank card payment

   Newer Mer stations have a contactless payment terminal. Look for a card reader with the contactless payment symbol. Tap your bank card or phone to start.

5. 5

   Try a Mer-issued RFID card for future visits

   You can order an RFID card directly from Mer through their app or website. Mer's own cards are accepted at all Mer stations without roaming issues.

Charger screen showing error but no error code

The charger screen displays a generic error message like "Error" or "Fault" without any specific code or explanation. This makes it hard to know if the problem is temporary or if the unit is broken.

Symptoms

• Charger screen shows "Error" or a red warning icon with no further detail
• The error appears before you even try to authenticate
• The error appears after plugging in but before power delivery starts
• Screen alternates between the normal start screen and the error message

How to Fix It

1. 1

   Unplug the connector and wait 30 seconds

   Some Mer chargers show transient errors after a previous session ended abnormally. Unplugging and waiting gives the charger time to reset its internal state.

2. 2

   Try the other connector on the same unit

   If the station has a second CCS2 connector, try that one. A hardware fault on one connector does not always affect the other.

3. 3

   Check if other cars are successfully charging at the station

   If nobody at the station is charging, the entire station may be down. If others are charging fine, the issue is limited to your connector.

4. 4

   Report the faulty unit in the Mer app

   Open the Mer app, find the station, and report the issue. Include which connector number has the error. This helps Mer send a technician and warns other drivers.

5. 5

   Move to a different station

   A charger with a persistent generic error is unlikely to start working on its own. Use the Mer app to find the nearest alternative station.

Cable locked and will not release in cold weather

You finished charging but the CCS2 cable will not unlock from your car. In Nordic winters, ice can form around the connector locking mechanism, making it physically difficult to release.

Symptoms

• Pressing the connector release button does not unlock the cable
• The connector feels frozen in place
• Your car shows "Charging complete" but the cable is stuck
• The locking pin on the connector is visibly iced over

How to Fix It

1. 1

   Make sure the charging session has fully ended

   The cable stays locked while a session is active. Stop the session in the Mer app or on the charger screen, then try releasing the connector again. Wait 10 seconds after the session ends.

2. 2

   Try unlocking from your car

   Most EVs have a cable release option in the infotainment system or a button near the charge port. Use your car's unlock function rather than the connector button.

3. 3

   Warm the connector gently

   If ice is the problem, pour lukewarm water (not boiling) over the connector and charge port area. You can also cup your hands around the connector to warm it with body heat. Do not use force or tools to pry it free.

4. 4

   Run the car's cabin heater for a few minutes

   Turning on the car's climate system can gradually warm the charge port area from the inside. This works slowly but can free a mildly frozen connector after 5-10 minutes.

5. 5

   Call Mer support if the cable is truly stuck

   If nothing works after 15 minutes, call the support number on the charger. Mer can remotely release the cable lock on their end. Do not pull with excessive force as this can damage both the connector and your car's charge port.

App requires location services for remote start

The Mer app asks you to enable location services before you can start a charging session, even when you are standing right next to the charger and selected it manually from the map.

Symptoms

• App shows "Enable location services to start charging" popup
• Start button is grayed out until location permission is granted
• The app worked fine before but now demands location after an update
• You can browse the map but cannot start a session without GPS enabled

How to Fix It

1. 1

   Enable location services temporarily

   Go to your phone's settings, find the Mer app, and set location access to "While Using the App." You can change it back after your session.

2. 2

   Make sure GPS has a fix

   In underground parking garages or areas with poor GPS reception, the app may not be able to confirm your location. Step outside or move closer to an open area until the app detects your position.

3. 3

   Use RFID or contactless payment instead

   If you do not want to share your location, use your RFID card or a contactless bank card to start the session. These methods do not require the app at all.

4. 4

   Scan the QR code on the charger

   Some Mer chargers have a QR code that opens the start process in a browser, bypassing the app's location requirement.

Former Grønn Kontakt station not found in Mer app

Mer acquired Grønn Kontakt in Norway, but some older stations may not appear correctly in the Mer app, especially during the transition period.

Symptoms

• Station visible on the street but not on the Mer app map
• Searching by the old Grønn Kontakt name returns no results
• QR code on the charger links to a Grønn Kontakt page that no longer works
• RFID card from Grønn Kontakt account rejected

How to Fix It

1. 1

   Update the Mer app to the latest version

   Older versions of the app may not include recently migrated Grønn Kontakt stations. Update from the App Store or Google Play.

2. 2

   Search by the station's physical address

   Instead of searching by station name, try the street address or zoom into the location on the app map. The station may appear under a new Mer name.

3. 3

   Enter the charger ID manually

   Look for a station or connector ID printed on the charger hardware. Enter this ID in the Mer app's manual start option.

4. 4

   Use contactless payment to bypass the app

   If the station has a payment terminal, tap your bank card to start. This works independently of whether the app has the station listed.
