Polestar 2 Charging at Mer

Polestar 2 Charger Won't Start or Begin Charging

You have plugged in your Polestar 2, the connector clicked, but nothing happens. The center display stays silent or shows an error. This is frustrating, but it is almost always fixable on the spot without calling support.

Symptoms

• CCS2 or Type 2 connector plugged in but no charging indicator on the center display
• Charger screen shows 'Waiting for vehicle' or stays on the start screen
• Polestar 2 charge port LED blinks but charging never begins
• Authentication succeeds on the charger but the session fails to start
• Center display briefly shows charging screen, then returns to idle

What to Do

1. 1

   Unplug and reconnect firmly

   Remove the CCS2 or Type 2 connector, wait 10 seconds, then reinsert it with a firm push until you hear a clear click. Watch the charge port LED on the Polestar 2 for a steady light.

2. 2

   Check for a charging schedule

   On the center display, go to Settings, then Charging. If a charging schedule is active, disable it or set it to 'Direct' so the car charges immediately when plugged in.

3. 3

   Restart the charger session

   On the charger, end the current session if one is shown. Then start a new session by tapping your RFID card or restarting in the charger's app. Some chargers have a physical start/stop button.

4. 4

   Try Plug & Charge or a different payment method

   If your Polestar 2 has Plug & Charge enabled, check the charger supports it. Otherwise, switch to a different RFID card, contactless payment, or the charger operator's app.

5. 5

   Reboot the car's infotainment system

   Press and hold the home button on the center display for about 15 seconds until the screen goes dark and restarts. Once it is back, try plugging in again. This resets the charging communication module.

6. 6

   Try a different charger or cable

   If the station has multiple stalls, move to a different one. If you are using a tethered cable, try bringing your own Type 2 cable. A faulty charger cable is more common than a faulty car.

Polestar 2 Charging Payment Failed at the Station

You are at the charger, your Polestar 2 is ready, but the payment will not go through. The charger says 'Authorization failed' or just does nothing after you tap your card. Payment issues are one of the most common reasons a charging session never starts, and they are usually fixable in a couple of minutes.

Symptoms

• Charger screen shows 'Authorization failed' or 'Payment declined' after tapping your card or RFID
• Charger app shows an error when trying to start a remote session for your Polestar 2
• Contactless bank card is declined even though it works at shops
• Plug & Charge does not activate automatically after plugging in the CCS2 connector
• Charger accepts payment but the session immediately ends with a zero-kWh charge

What to Do

1. 1

   Check if Plug & Charge is enabled

   On the Polestar 2 center display, go to Settings, then Charging. Confirm Plug & Charge is turned on. If it is on but the charger did not start automatically, this station likely does not support it. Use a different payment method.

2. 2

   Try the charger operator's app

   Look for the operator name on the charger (Ionity, Shell Recharge, Allego, etc.). Download their app if you do not have it, add a payment method, and start the session through the app. Make sure you select the correct stall number shown on the charger.

3. 3

   Try a different RFID card or payment method

   If you carry multiple charging cards, try a different one. Some roaming cards work across many networks. If you only have one card, try contactless payment with your bank card or phone if the charger supports it.

4. 4

   Check your bank card's available balance

   Open your banking app and check that you have enough available balance for the pre-authorization hold, which can be up to 50 EUR even for a short charge. Pending holds from previous charging sessions can temporarily reduce your available balance.

5. 5

   Restart the charger and try again

   Some chargers have a stop/reset button. Press it, wait for the screen to return to the start screen, then begin a fresh session. If there is no button, unplug your Polestar 2, wait 30 seconds, and replug.

6. 6

   Move to a different charger

   If nothing works at this stall, try a different stall at the same station. Payment terminals can fail independently. If the entire station is down, find the nearest alternative using the charger map on your Polestar 2 center display or Google Maps.

Polestar 2 Charging Slower Than Expected

You plugged in your Polestar 2 expecting 149 kW and the screen shows 40 kW. Or your home charger is stuck at 3 kW instead of 11 kW. Slow charging on the Polestar 2 is almost never a defect. It is usually the battery temperature, the charger itself, or a setting you can fix in two minutes.

Symptoms

• DC fast charging speed well below the 149 kW maximum
• AC home charging stuck at 3-4 kW instead of 11 kW
• Charging speed drops significantly after reaching 50-60%
• Charging session starts normally but slows down quickly
• Dashboard shows lower power than the charger's rated output

What to Do

1. 1

   Check the battery temperature

   Look at the charging screen on the center display. If the battery is cold (common in winter), drive for 15-20 minutes before charging or use the preconditioning feature through the Polestar app before arriving at the charger.

2. 2

   Check your state of charge

   If you are above 80%, the slower speed is normal. For fastest charging, arrive at the charger between 10-20% and charge to 80%.

3. 3

   Verify the charger is not shared

   Look at the charger unit. If there are two cables and someone is using the other one, you may be sharing power. Move to an unoccupied charger if available.

4. 4

   Check the AC charge current setting

   In the Polestar 2, go to Settings, then Charging. Make sure the charge current limiter is set to maximum. If it shows a lower value, increase it.

5. 5

   Try a different charger

   If the speed is still low, the charger itself may be degraded or faulty. Try a different charger at the same location or a different charging station.

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.
