Volvo EX90 Charging at Mer

Volvo EX90 Plugged In but the Charger Will Not Start

You connected the cable to your Volvo EX90 and nothing happens. No charging indicator on the screen, no confirmation from the charger. The EX90 supports Plug & Charge and multiple authentication methods, but when none of them work, you need to troubleshoot step by step.

Symptoms

• Charger displays an error after plugging in the EX90
• Charge port LED does not light up or stays amber
• 14.5-inch center screen shows no active charging session
• Charger screen says 'waiting for vehicle' or shows a timeout
• CCS connector plugs in but does not lock into the charge port

What to Do

1. 1

   Authenticate with the charger

   Check the charger's screen for payment instructions. Tap your RFID card, open the charging network's app, or use contactless payment. Plug & Charge should activate automatically on supported networks, but if it does not, use manual authentication.

2. 2

   Check the charge port on the left rear

   Open the charge port door fully. Check for ice, snow, or debris. In winter, gently clear any obstructions. Make sure the port cover is not partially blocking the connector.

3. 3

   Seat the connector firmly

   Push the CCS2 connector straight into the port until it clicks and locks. If it will not lock, pull it out and try again. Check that the connector pins are clean and undamaged.

4. 4

   Turn off scheduled charging

   On the center screen, go to Settings, then Charging. If a charging schedule is active, disable it or switch to 'charge immediately.' This is a common reason charging will not start at public chargers.

5. 5

   Restart the charging process

   Unplug the connector, lock and unlock the car using the Volvo Cars app or key, wait 15 seconds, then plug in again. This resets the charging communication.

Volvo EX90 Charger Payment Failed or Card Declined

You are at a public charger with your Volvo EX90 and the payment will not go through. The card reader rejects your card, the app throws an error, or Plug & Charge just does not activate. Payment issues at public chargers are one of the most common frustrations, and they have nothing to do with your car's charging system.

Symptoms

• Charger screen shows 'payment failed' or 'card declined'
• Plug & Charge does not activate when you connect the cable
• Charging app shows a payment error or insufficient balance
• Contactless payment terminal does not respond
• You cannot find any way to pay at the charger

What to Do

1. 1

   Check Plug & Charge status in the Volvo Cars app

   Open the Volvo Cars app and verify that Plug & Charge is enabled with a valid payment method. If the network supports it, try unplugging and reconnecting. If not, proceed to manual payment.

2. 2

   Try a different payment method

   Use a different credit or debit card, your phone's mobile wallet, or the charging network's app. Having multiple options avoids being stuck when one fails.

3. 3

   Check for pre-authorization holds

   Open your banking app and look for pending charges from the charging network. Multiple failed attempts may have placed several holds, reducing your available balance. Contact your bank if needed.

4. 4

   Use the charging network's app instead

   Find the network name on the charger. Download their app, create an account, add a payment method, and start the session through the app. This bypasses the physical payment terminal entirely.

5. 5

   Tap your RFID charging card

   If you carry an RFID card from a charging provider or roaming service, tap it on the charger's card reader. RFID cards are often more reliable than apps or contactless terminals.

Volvo EX90 Charging Slower Than Expected at DC or AC

You plugged in your Volvo EX90 expecting 250 kW and the 14.5-inch screen shows 60 kW. Or your wallbox is only delivering 3 kW instead of 11 kW. The EX90 has one of the fastest charging speeds in its class, but reaching that peak depends on battery temperature, state of charge, and the charger itself.

Symptoms

• DC fast charging speed well below the 250 kW maximum
• AC home charging stuck at 3-4 kW instead of 11 kW
• Charging speed drops sharply after reaching 40-50%
• Center screen shows lower power than the charger's rated output
• Charging session starts strong but slows down within 10 minutes

What to Do

1. 1

   Set the charger as your navigation destination

   Use Google Maps on the 14.5-inch center screen to navigate to the charging station. The EX90 will start preconditioning the battery automatically during the drive, preparing it for peak charging speed.

2. 2

   Check the charger's rated power

   Before plugging in, check the charger's label or the app for its maximum output. If the charger is rated at 150 kW, your EX90 cannot charge faster than 150 kW regardless of its 250 kW capability.

3. 3

   Check your state of charge

   For the fastest charging, arrive between 10-20%. The EX90's peak speeds are available at lower states of charge. Above 80%, charging will slow significantly.

4. 4

   Verify the charger is not sharing power

   Many chargers split power between two connectors. If someone is using the adjacent stall, both cars get reduced speeds. Move to a charger with both stalls free.

5. 5

   Check AC charge current settings

   If charging slowly on AC, check the EX90's settings to ensure the charge current limiter is set to maximum. Also verify your wallbox is properly wired for 3-phase.

6. 6

   Try a higher-powered charger

   To take advantage of the EX90's 250 kW capability, look for chargers rated at 300 kW or higher. These are available from networks like Ionity, Fastned, and others.

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.
