Volvo EX40 Charging at Tesla Supercharger

Volvo EX40 Plugged In but the Charger Will Not Start

You plugged the cable into your Volvo EX40 and nothing happens. No charging animation on the center screen, no LED on the charger, or the charger shows an error. This is one of the most common frustrations at public chargers and is usually caused by authentication, the charge port, or the charger itself.

Symptoms

• Charger displays an error code or flashing red light after plugging in
• Charge port LED on the EX40 does not turn on or stays amber
• Google Built-In display shows no active charging session
• Charger screen says 'waiting for vehicle' or 'authentication failed'
• Cable is plugged in but the connector does not lock into the charge port

What to Do

1. 1

   Check if authentication is required

   Look at the charger's screen. Most public chargers need you to tap an RFID card, scan a QR code, or start the session through an app before charging begins. Plug & Charge works on some networks but not all.

2. 2

   Open the charge port fully

   Make sure the charge port door on the left rear of your EX40 is fully open. Press the edge of the door to release it if it is stuck. Clear any ice or debris in cold weather.

3. 3

   Push the connector in firmly

   Insert the CCS connector straight into the port and push until you hear a click. The connector should lock in place. If it will not lock, do not force it. Check for debris in the port.

4. 4

   Disable scheduled charging

   On the center display, go to Settings, then Charging. Check if a charging schedule is active. Turn it off or set it to 'charge immediately' to start charging at a public charger.

5. 5

   Unplug and try again

   Disconnect the cable, wait 10 seconds, and plug in again. Sometimes the communication handshake between car and charger fails on the first attempt and a retry resolves it.

6. 6

   Try a different charger or connector

   If the charger still will not start, move to a different stall or station. The charger may have an internal fault even if no error is displayed.

Volvo EX40 Charger Payment Failed or Card Declined

You are standing at a charger with your Volvo EX40, ready to charge, and the payment does not go through. Your card is declined, the app shows an error, or you cannot figure out how to pay at all. Payment problems at public chargers are one of the most common frustrations and usually have nothing to do with your car.

Symptoms

• Charger screen shows 'payment failed' or 'card declined'
• Charging app shows an error when trying to start a session
• No visible way to pay at the charger
• Contactless payment terminal does not respond to your card or phone
• Plug & Charge does not activate and the charger waits for payment

What to Do

1. 1

   Check if Plug & Charge is active

   Open the Volvo Cars app and check if Plug & Charge is enabled and linked to a payment method. If it is active, try unplugging and replugging the connector. Plug & Charge works only on supported networks.

2. 2

   Try a different payment method

   If your card was declined, try a different card, your phone's mobile wallet, or the charger network's app. Many chargers accept multiple payment options.

3. 3

   Check your card for pre-authorization holds

   Open your banking app and check for pending charges. If there are multiple holds from earlier charging attempts, your available balance may be too low. Call your bank to release them if needed.

4. 4

   Download the charger network's app

   Look at the charger for the network name or logo. Download their app, create an account, add a payment method, and start the session through the app instead of the charger's payment terminal.

5. 5

   Use an RFID charging card

   If you have an RFID card from a charging provider, tap it on the charger's reader. RFID cards work even when apps and contactless terminals fail. They are a reliable backup.

Volvo EX40 Charging Slower Than Expected at DC or AC

You plugged in your Volvo EX40 expecting 150 kW and the center screen shows 30 kW. Or your home wallbox is stuck at 3 kW instead of 11 kW. Slow charging on the EX40 is almost never a defect. It is usually the battery temperature, the charger itself, or a setting in the Volvo Cars app you can fix quickly.

Symptoms

• DC fast charging speed well below the 150 kW maximum
• AC home charging stuck at 3-4 kW instead of 11 kW
• Charging speed drops sharply after reaching 50-60%
• Google Built-In display shows lower power than the charger's rating
• Charging session starts at a reasonable speed but slows within minutes

What to Do

1. 1

   Check the battery temperature on the display

   Look at the charging screen on the EX40's center display (Google Built-In). If the battery is cold, drive for 15-20 minutes before charging or use the Volvo Cars app to start preconditioning before you arrive.

2. 2

   Use navigation to precondition the battery

   Set the charger as your destination in Google Maps on the center screen. The EX40 will automatically precondition the battery during the drive so it reaches optimal temperature for fast charging.

3. 3

   Check your state of charge

   If you are above 80%, the slower speed is normal. For fastest DC charging, arrive between 10-20% and charge to 80%. The last 20% takes as long as the first 80%.

4. 4

   Verify the charger is not sharing power

   Look at the charging unit. If there are two cables and someone is using the other one, you are likely sharing power. Move to a charger where both stalls are free.

5. 5

   Check the AC charge current setting

   In the EX40's settings menu, check that the charge current limiter is set to maximum. A reduced setting limits AC charging speed and is sometimes changed accidentally.

6. 6

   Try a different charger

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

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.
