Volvo EX90 Charging at Tesla Supercharger

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.

Non-Tesla vehicle cannot find the station in the Tesla app

You arrive at a Supercharger with your non-Tesla EV but the station does not appear in the Tesla app, or it shows as Tesla-only.

Symptoms

• Tesla app shows the station but does not list it as open to other brands
• Station appears on the map but the 'Start Charging' button is grayed out
• App says 'This location is not available for your vehicle'
• You can see other non-Tesla vehicles charging but the app will not let you start

How to Fix It

1. 1

   Confirm the station is open to non-Tesla vehicles

   Not all Supercharger locations are open to other brands. In the Tesla app, look for stations marked with a label indicating non-Tesla access. If there is no such label, the station is Tesla-only.

2. 2

   Update the Tesla app

   Tesla frequently adds new non-Tesla locations. If your app is outdated, recently opened stations may not appear as accessible. Update to the latest version.

3. 3

   Check your Tesla account setup

   You need a Tesla account with a valid payment method added, even if you do not own a Tesla. Open the app, go to your account settings, and confirm a credit or debit card is saved.

4. 4

   Try selecting the specific stall number

   After plugging in, open the Tesla app, select the station, and tap the stall number that matches the one you plugged into. The stall number is printed on the charger post.

5. 5

   Restart the Tesla app

   Force-close and reopen the app. Location and station data sometimes fails to load correctly on the first attempt.

Payment hold is larger than expected

Tesla places a pre-authorization hold on your payment method when you start a Supercharger session. This hold can be surprisingly large and may temporarily reduce your available balance.

Symptoms

• Bank notification shows a hold of 50 to 120 EUR before charging begins
• Available balance on your debit card drops significantly
• Multiple holds appear from previous sessions that have not been released yet
• Hold amount does not match the actual charging cost

How to Fix It

1. 1

   Understand that holds are temporary

   Tesla pre-authorizes a fixed amount to ensure payment. The actual charge replaces the hold once the session is complete. The hold typically releases within 1 to 5 business days depending on your bank.

2. 2

   Use a credit card instead of a debit card

   Credit cards handle pre-authorization holds without affecting your available cash balance. Debit cards temporarily lock the held amount from your account.

3. 3

   Check the Tesla app for final session cost

   After charging, the Tesla app shows the actual amount you will be billed. This is always less than or equal to the pre-authorization hold.

4. 4

   Contact your bank if holds persist beyond 7 days

   If a hold has not been released after a week, contact your bank and provide the transaction reference from the Tesla app. Banks can manually release stale holds.

Session ends early or stops unexpectedly

Charging stops before reaching your target battery level. The car disconnects or the Supercharger stops delivering power mid-session.

Symptoms

• Charging stops at 80% even though you set a higher limit
• Session ends after a few minutes with no error message
• Car shows 'Charging interrupted' or 'Check charge cable'
• Supercharger light turns from green to red or flashing

How to Fix It

1. 1

   Check your charge limit setting

   Tesla vehicles default to an 80% charge limit. Non-Tesla vehicles have their own limit settings in the infotainment system. Verify you have set the limit above where charging stopped.

2. 2

   Reseat the cable connector

   Unplug the cable, inspect the connector and your vehicle's charge port for debris, and plug it back in firmly. A loose connection can cause the session to drop.

3. 3

   Try a different stall

   Individual Supercharger stalls can have intermittent faults. Move to another stall, preferably one that is not paired with an active session (stalls sharing a power cabinet are usually labeled with paired numbers like 1A/1B).

4. 4

   Check for idle fees

   If you reached your charge limit and did not unplug promptly, Tesla may have ended the session and started idle fees. Check the Tesla app for notifications.

5. 5

   Restart your vehicle

   For non-Tesla vehicles, turn the car off completely, wait 30 seconds, and turn it back on. Then plug in again. Some vehicles need a restart to clear communication errors with the Supercharger.

Reduced charging speed due to power sharing

Your charging speed is significantly lower than the station's advertised maximum. This often happens because Supercharger stalls share power with a paired stall.

Symptoms

• Charging at 60 to 80 kW at a station rated for 250 kW
• Speed dropped when another vehicle plugged in at a nearby stall
• Speed is much lower than you got at the same station previously
• One stall charges fast while the paired stall is very slow

How to Fix It

1. 1

   Move to an unpaired stall

   Tesla Supercharger stalls are paired (for example, 1A and 1B share a power cabinet). If someone is using 1A, stall 1B will be slower. Choose a stall where neither paired unit is occupied.

2. 2

   Look at the stall labels

   Paired stalls usually share a number with A/B suffixes, or are directly adjacent. At V3 Superchargers (250 kW), power sharing is less of an issue than at older V2 stations (150 kW).

3. 3

   Check your battery temperature

   Tesla vehicles precondition the battery automatically when navigating to a Supercharger. If you did not use Tesla navigation (or you drive a non-Tesla), the battery may be cold and limiting charge speed on its own.

4. 4

   Arrive with a lower state of charge

   Charging speed decreases as the battery fills. For the fastest stop, arrive between 5 and 20% if you can do so safely. The difference in charge speed between arriving at 10% versus 40% is significant.

Non-Tesla vehicle CCS2 connector issues

At Supercharger stations open to non-Tesla vehicles, the CCS2 connector may not work correctly with your car. In Europe, open Supercharger stations have native CCS2 cables, so no adapter is needed.

Symptoms

• The CCS2 connector does not lock into your vehicle's charge port
• Session starts but drops after a few seconds
• Tesla app does not recognize your vehicle after plugging in
• The connector fits but no power is delivered

How to Fix It

1. 1

   Make sure you are using the CCS2 cable, not the Tesla connector

   Open Supercharger stations in Europe have separate CCS2 cables alongside Tesla connectors, or dedicated CCS2 posts. Use the CCS2 cable for non-Tesla vehicles.

2. 2

   Push the connector in firmly until it clicks

   CCS2 connectors need a firm push to fully seat and lock. If the connector is loose, the charger cannot communicate with your vehicle.

3. 3

   Start the session through the Tesla app

   Select the correct stall number in the Tesla app and start the session. The stall number is printed on the charger post. It must match exactly.

4. 4

   Try a different stall

   Individual stalls can have faulty connectors. Move to another stall, preferably one that is not paired with an active session.

5. 5

   Check vehicle compatibility

   Not all non-Tesla vehicles work perfectly at every Supercharger station. If your vehicle repeatedly fails to connect, check Tesla's website or app for your vehicle's compatibility status.
