MG MG5 Charging at Tesla Supercharger

MG MG5 Charger Won't Start? Step-by-Step Help

You have plugged in your MG MG5 and the charging session refuses to start. The charger might be blinking, showing an error, or doing nothing at all. This is a common problem across all EVs, and the MG5 is no exception. Most causes are easy to diagnose and fix on the spot.

Symptoms

• Charger display shows an error or stays on the start screen
• CCS2 connector plugs in but charging does not initiate
• MG5 charge port light does not turn on or stays amber
• App shows the charger as available but the session does not begin
• AC Type 2 cable locks in but no power flows

What to Do

1. 1

   Read the charger screen

   Check for error messages, authentication prompts, or status indicators. If it says 'waiting for vehicle' the problem is on the car side. If it says 'error' or 'out of service,' the charger is the issue.

2. 2

   Unplug, wait, and replug

   Remove the connector completely, wait 15 seconds, and reinsert it firmly. Listen for the locking click on the MG5's charge port. This resets the communication handshake.

3. 3

   Complete authentication

   Tap your RFID card, open the network app and start the session, or use contactless payment. Some chargers need you to authenticate before plugging in, others after.

4. 4

   Check for scheduled charging

   Go to the MG5's charging settings on the infotainment screen. If a charging schedule is active, disable it to allow immediate charging.

5. 5

   Restart the car's systems

   Turn the MG5 off using the start button, wait 30 seconds, then turn it back on. This can clear temporary software glitches that prevent the charge port from communicating.

6. 6

   Move to another stall or station

   If the charger is at fault, try another stall. If no stalls work, the station may have a site-wide issue. Find an alternative station using your charging app.

MG MG5 Charging Payment Failed? How to Fix It

You are standing at a charger with your MG MG5 and the payment will not work. Card declined, app throwing errors, or no idea how to pay at all. This is one of the most frustrating parts of public charging, and it happens to everyone. Here is how to get past it.

Symptoms

• RFID card not recognized when tapped on the charger
• Charging app shows payment error or transaction declined
• Contactless card payment rejected at the terminal
• Charger starts authentication but then returns an error
• Session begins but ends immediately due to payment failure

What to Do

1. 1

   Identify accepted payment methods

   Look at the charger for payment logos and instructions. Note whether it accepts RFID cards, specific apps, contactless cards, or QR code payments. Each charger may support different methods.

2. 2

   Try the network's own app

   Download the charger network's app, create an account, and add a payment method. Then start the session through the app. This bypasses RFID and contactless issues.

3. 3

   Switch to an alternative payment method

   If your primary RFID card fails, try contactless with your bank card. If that fails, try a roaming provider like Plugsurfing, Shell Recharge, or Chargemap.

4. 4

   Check your bank for blocked transactions

   Open your banking app and look for declined or pending transactions. If the pre-authorization was blocked, call your bank or temporarily increase your card limit.

5. 5

   Try a different stall

   If the card reader on one stall is broken, another stall at the same station may have a working reader. Try the next one before giving up on the location.

6. 6

   Find an alternative station

   Use your charging app to find a nearby station from a network where your payment methods are confirmed to work. Filter by your preferred payment method if the app supports it.

MG MG5 Charging Slowly? Why and How to Fix It

Your MG MG5 is charging slower than you expected. With a maximum DC speed of 87kW, the MG5 is not the fastest charger in its class, but it should still deliver reasonable speeds. If you are seeing numbers well below that, something else is going on. Here is what to check.

Symptoms

• DC charging power showing well below 87kW on the charger display
• AC charging stuck below 11kW on a capable wallbox
• Estimated charging time significantly longer than expected
• Charging speed drops sharply above 50-60% SOC
• Very slow charging in cold weather conditions

What to Do

1. 1

   Check the charger's maximum power output

   Verify the charger is rated above 87kW. If it is a 50kW charger, the MG5 is getting the maximum available. Look at the charger label or check in the network app.

2. 2

   Use preconditioning in cold weather

   Set the fast charger as your destination in the MG5's navigation system. This activates battery preconditioning, which warms the battery before you arrive and improves initial charging speed.

3. 3

   Check your state of charge

   If you are above 60% SOC, the MG5's charging taper is expected. For the fastest session, arrive at the charger between 10-20% SOC and charge to 70-80%.

4. 4

   Try a different stall to avoid power sharing

   If the station shares power between stalls, wait for other cars to finish or move to a stall that is not paired with another active charger. Some stations label which stalls share power.

5. 5

   For AC, verify your cable and charger

   Make sure you are using a 3-phase Type 2 cable on an 11kW or higher AC charger. A single-phase connection limits you to about 3.6kW, which adds many hours to a full charge.

6. 6

   Check car settings for charging limits

   In the MG5's settings, look for any AC current limit or maximum charge level that might be capping your speed.

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.
