MG ZS EV Charging at Mer

MG ZS EV Charger Won't Start? Quick Fix Guide

You have connected the charger to your MG ZS EV but nothing happens. No power flowing, the charger is showing an error, or the car just does not respond. Before you give up and drive to another station, run through these checks. Most charging failures have a simple fix.

Symptoms

• Charger display shows error after plugging in the CCS2 connector
• Charge port light on the ZS EV does not illuminate
• Car dashboard shows no indication of charging activity
• Charger screen stays on the welcome or authentication screen
• Type 2 AC connector locks in but charging does not begin

What to Do

1. 1

   Check the charger display for errors or instructions

   Look at the charger screen. It will tell you if authentication is needed, if there is a fault, or if it is waiting for the vehicle. This is the fastest way to identify the problem.

2. 2

   Remove and reinsert the connector

   Pull the CCS2 or Type 2 connector out completely, wait 10-15 seconds, and push it back in firmly. Make sure it locks into the ZS EV's front charge port.

3. 3

   Authenticate with the charger

   Tap your RFID card, start the session in the network app, or use contactless payment. Try authenticating both before and after plugging in, as different chargers have different sequences.

4. 4

   Check the charge port for obstructions

   Inspect the ZS EV's charge port for debris, ice, or visible damage to the pins. In winter, gently remove any ice with your hand or a soft cloth. Do not use metal tools.

5. 5

   Turn the car off and back on

   Switch the ZS EV off completely, wait 30 seconds, then turn it on again. This resets the onboard charging system and can resolve communication glitches.

6. 6

   Try another stall or station

   If the charger is faulty, move to another stall. If the entire station is down, find a nearby alternative using your charging app.

MG ZS EV Charging Payment Failed? Solve It Fast

Your MG ZS EV is plugged in and ready to charge, but the payment is not going through. Whether it is an RFID card, an app, or a bank card, payment failures are among the most common reasons charging sessions fail to start. Here is how to get it sorted and get on with your charge.

Symptoms

• RFID card tap produces no response from the charger
• Network app shows a payment declined error
• Contactless card is rejected at the charger terminal
• Charger asks for authentication but nothing you try works
• Charging starts then stops within seconds due to billing error

What to Do

1. 1

   Check what payment methods the charger accepts

   Look at the charger for payment logos, QR codes, or instructions. Identify whether it takes RFID, app payments, contactless cards, or a specific network's card only.

2. 2

   Try the charger network's own app

   Scan the QR code on the charger or search for the network's app. Register, add a payment method, and try starting the session through the app.

3. 3

   Try alternative payment methods

   Switch between RFID card, contactless bank card, and app-based payment. If you have a roaming provider like Plugsurfing or Shell Recharge, try their card or app.

4. 4

   Check your bank for declined transactions

   Open your banking app to look for blocked pre-authorizations or declined charges. If the hold was blocked, you may need to approve it or use a different card.

5. 5

   Try a different stall

   The card reader on one stall may be faulty while others work fine. Move to the next stall and try again.

6. 6

   Find a nearby compatible charger

   If nothing works at this station, use your charging app to find an alternative. Filter by networks where your payment methods are confirmed to work.

MG ZS EV Charging Slowly? Causes and Solutions

Your MG ZS EV is taking much longer to charge than you expected. With a 94kW maximum DC speed and no battery preconditioning, the ZS EV is particularly affected by cold weather and charging conditions. Understanding these limits helps you plan better and avoid frustration at the charger.

Symptoms

• DC fast charging power well below 94kW
• AC charging not reaching the full 11kW
• Very slow charging in cold or winter conditions
• Charging speed drops significantly above 50-60% SOC
• First fast charge of the day is much slower than subsequent ones

What to Do

1. 1

   Verify the charger's maximum output

   Check the charger label or app for its power rating. If it is a 50kW unit, the ZS EV cannot charge faster. Look for chargers rated at 100kW or above to access the full 94kW capability.

2. 2

   Drive longer before charging in cold weather

   Since the ZS EV has no preconditioning, the best way to warm the battery is to drive. A longer highway drive before the charger will raise the battery temperature naturally, improving DC charging speed.

3. 3

   Charge at a lower SOC

   Arrive at the charger between 10-20% SOC for the fastest charging speeds. The ZS EV delivers its best power in the 10-50% range.

4. 4

   Choose a stall without power sharing

   If the station shares power between stalls, pick one where the adjacent stall is empty. This gives you the full power allocation.

5. 5

   Check your AC cable and charger

   For AC charging, verify you are using a 3-phase Type 2 cable on an 11kW charger. A single-phase connection limits you to about 3.6kW.

6. 6

   Accept the winter speed reality

   In cold weather, the ZS EV's lack of preconditioning and heat pump means slow starts are unavoidable. Plan for longer charging stops in winter and consider parking in a heated garage when possible.

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.
