BMW i7 Charging at Tesla Supercharger

BMW i7 Charger Won't Start: Step-by-Step Fix Guide

You have connected your BMW i7 to a public charger, but the session refuses to start. No charging indicator, no power, just frustration. This is a common issue that usually comes down to authentication, cable seating, or charger status. Here is what to check.

Symptoms

• Charger display shows 'waiting for vehicle' despite the cable being connected
• iDrive does not indicate any charging activity
• The i7's charge port LED stays off or flashes red
• The CCS2 connector does not lock into the port
• An error message appears on the charger screen after plugging in

What to Do

1. 1

   Unlock the car and open the charge port

   Ensure the i7 is unlocked. Press the charge port flap on the rear right side to open it. Some i7 models also let you open it through the My BMW app.

2. 2

   Insert the connector until it clicks

   Push the CCS2 or Type 2 connector straight into the port firmly. You should hear a click when it locks. The i7's port LED should illuminate once the connection is established.

3. 3

   Authenticate at the charger

   Tap your RFID card on the reader, start the session in your charging app, or use contactless payment at the terminal. Wait for the charger to confirm before expecting power flow.

4. 4

   Disable scheduled charging

   In iDrive, navigate to Charging Settings. If departure time or a schedule is set, switch to Charge Immediately. This ensures the i7 starts as soon as the charger is ready.

5. 5

   Disconnect and retry

   Remove the cable, wait 15 seconds, and reconnect. This resets the communication protocol between the i7 and the charger.

6. 6

   Try another charger

   If nothing resolves the issue, the charger is likely faulty. Move to a different stall or station and report the broken unit through the network's app.

BMW i7 Charging Payment Failed: How to Resolve Fast

Your BMW i7 is plugged in at a public charger, but the payment will not go through. RFID card not recognized, app error, or bank card declined. This is not a car issue, but it blocks your charging session all the same. Here is how to work through it.

Symptoms

• The charger shows 'authentication failed' after tapping your RFID card
• Your charging app displays a payment error when starting a session
• Contactless bank card is declined at the charger terminal
• The charger prompts for payment but none of your methods work
• A session starts then immediately cancels due to a billing issue

What to Do

1. 1

   Try an alternative payment method

   Switch from RFID to the charging app, or from the app to contactless bank card. Most chargers accept at least two payment methods.

2. 2

   Check your account and card details

   Open your charging app and verify the linked payment method is current. For prepaid accounts, ensure your balance covers the session.

3. 3

   Verify the charger accepts your provider

   Look at the charger for logos of accepted networks. If yours is not listed, you need ad-hoc payment or a different card.

4. 4

   Use the QR code for ad-hoc payment

   Scan the QR code on the charger with your phone camera. This opens a browser-based payment page where you can pay with any credit or debit card, no app required.

5. 5

   Restart the authorization

   Cancel any pending session in the app and start fresh. Sometimes the first authorization attempt fails but a second one succeeds.

6. 6

   Contact the network's support line

   Most chargers display a phone number for the operator. They can sometimes authorize a session on their end or identify the specific payment issue.

BMW i7 xDrive60 Charging Slow: Causes and Solutions

Your BMW i7 xDrive60 has a large 101.7kWh battery and supports up to 195kW DC fast charging. But if the numbers on iDrive are disappointing, you are not alone. Several factors can limit the i7's charging speed, and knowing what to look for helps you get the most out of every stop.

Symptoms

• DC fast charging power shown in iDrive is well below 195kW
• The large 101.7kWh battery takes much longer than expected to charge
• Charging curve drops off steeply after 40-50%
• AC charging speed is limited to 11kW despite using a faster station
• A temperature or battery conditioning message appears in iDrive

What to Do

1. 1

   View charging details in iDrive

   The iDrive display shows current kW, battery temperature, and time remaining. Check whether the car or the charger is the bottleneck by comparing the current kW to the charger's rated output.

2. 2

   Precondition before every fast charge

   Enter the charging station as a destination in iDrive. The i7's thermal management will bring the battery to the ideal temperature range while driving. This is the single biggest factor in cold weather charging speed.

3. 3

   Find chargers rated 200kW or above

   Use the My BMW app or a charger map to locate high-power stations. Ionity and Fastned locations typically offer 300kW+ chargers that let the i7 reach its peak.

4. 4

   Choose an unoccupied charger pair

   If the station has paired stalls, pick one where the adjacent stall is empty. This avoids power sharing and gives your i7 full access to the charger's output.

5. 5

   Charge between 10% and 80%

   Plan stops to arrive between 10% and 15% and leave around 80%. The i7's large battery means even 80% gives you substantial range, and you avoid the slow tail end of the charging curve.

6. 6

   Check for OTA software updates

   BMW releases over-the-air updates that can improve charging behavior. Go to Settings, then Software Update in iDrive to check for and install any available updates.

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.
