The BMW i4's Charging Port
Your BMW i4 is equipped with a CCS (Combined Charging System) port for DC fast charging and a Type 2 (J1772 in North America) connector for AC (Level 1 and Level 2) charging. This is the standard for most non-Tesla EVs in North America and Europe.
The Tesla Charger Landscape
Tesla primarily uses its proprietary NACS (North American Charging Standard) connector. However, there are two main scenarios for Tesla charging:
Tesla Wall Connectors (Home/Destination Chargers): These are AC chargers, similar to Level 2 chargers you'd install at home.
Tesla Superchargers (DC Fast Chargers): These are Tesla's rapid DC charging stations.
Recently, Tesla has begun opening up its Supercharger network to other EVs, and many automakers, including BMW, are adopting the NACS standard for future vehicles. However, for your current BMW i4, you'll need a workaround.
The Adapter Solution: NACS to CCS1
To bridge the gap between your BMW i4's CCS port and a Tesla NACS charger, you'll need a NACS to CCS1 adapter. It's crucial to get the right type of adapter. A NACS to J1772 adapter will work for AC charging at Tesla Wall Connectors, but for Supercharging, you need a NACS to CCS1 adapter.
Important Note: While some third-party adapters are available, it's always wise to check if your vehicle manufacturer (BMW) recommends or will eventually provide an official adapter. There have been anecdotes about issues with aftermarket adapters, so proceed with caution and ensure you choose a reputable brand.
Step 2: Acquiring the Right Adapter – Your Gateway to Tesla Charging
This is a critical step, as the wrong adapter won't work or could potentially cause issues.
Identifying Compatible Adapters
QuickTip: Pause when something feels important.
For Level 1 and Level 2 AC charging (e.g., at a Tesla Wall Connector at a friend's house or a hotel), you'll need a NACS to J1772 adapter. Brands like Lectron and A2Z offer these. The A2Z adapter is often preferred for its higher amperage rating (up to 80A vs. Lectron's 48A), which can reduce the risk of overheating during longer AC charging sessions.
For DC Fast Charging at Tesla Superchargers, you'll need a NACS to CCS1 adapter. These adapters are designed to handle the higher power output of Superchargers. Some popular options include the Lectron Vortex Plug and the A2Z EV Typhoon Plug.
Where to Purchase
You can typically find these adapters online from EV accessory retailers, directly from the adapter manufacturers, or potentially from major online marketplaces. Always ensure you are purchasing from a trusted seller and verify the adapter's compatibility with your BMW i4 and the type of Tesla charger you intend to use (AC or DC).
Step 3: Charging at a Tesla Wall Connector (AC Charging)
If you're looking to charge your BMW i4 at a Tesla Wall Connector (Level 2 AC charger), here's the step-by-step process:
Sub-heading: Preparing for the Charge
Ensure the Tesla Wall Connector is Accessible: Confirm that the Tesla Wall Connector you intend to use is set to "Open to All" in its settings (this is often controlled by the owner/property manager). If it's restricted to Teslas only, your adapter won't work.
Retrieve Your NACS to J1772 Adapter: Have your adapter handy.
Park Your BMW i4: Position your vehicle so the charging port (located on the right rear side of your i4) is easily accessible by the Tesla charging cable.
Sub-heading: The Connection Process
Connect the Adapter to the Tesla Cable: Take the NACS end of your adapter and firmly plug it into the Tesla Wall Connector's cable. It should click securely into place.
Connect the Adapter to Your BMW i4: Now, take the J1772 end of the adapter (which is now attached to the Tesla cable) and plug it into your BMW i4's charging port. Again, ensure a firm and secure connection.
Monitor the Charging Indicator: Your BMW i4's dashboard or charging indicator lights should illuminate, indicating that charging has begun. You may also be able to monitor the charging status through the BMW app.
Adjust Charging Settings (Optional): If desired, you can adjust charging settings within your BMW i4's infotainment system, such as setting a charge limit.
Sub-heading: Ending the Charging Session
Stop Charging: You can typically stop the charging session from your BMW i4's infotainment system, or in some cases, by simply unplugging the connector from the car (though it's best practice to stop it from the car first).
Disconnect from Your BMW i4: Press the release button on the J1772 side of the adapter and carefully pull it out of your i4's charging port.
Disconnect the Adapter from the Tesla Cable: Carefully disconnect the adapter from the Tesla cable.
Return the Tesla Cable: Neatly return the Tesla charging cable to its holder.
Step 4: Charging at a Tesla Supercharger (DC Fast Charging) ⚡
Charging your BMW i4 at a Tesla Supercharger requires a NACS to CCS1 adapter and often the use of the Tesla app. Not all Superchargers are open to non-Tesla EVs yet, and some have "Magic Docks" (built-in adapters).

Always invest in a high-quality, reputable NACS to CCS1 adapter. Cheap or uncertified adapters can be unreliable, lead to slow charging, overheating, or even damage to your vehicle or the charging station. Look for adapters with good reviews and safety features.
Overheating
During DC fast charging, both the adapter and the car's charging system generate heat. If you experience charging faults due to excessive heat, allow the charger and adapter to cool down for about 30 minutes before attempting to charge again. This is a built-in safety feature.
Warranty Concerns
Some BMW dealerships have expressed reservations about using third-party adapters, citing potential warranty issues if damage occurs due to their use. While the car generally can't detect what you're plugging into it, any damage directly attributable to an aftermarket adapter might not be covered. It's advisable to check with your BMW dealer regarding their stance on third-party adapters.
Tesla Supercharger Access Control
Some Tesla Wall Connectors (especially at private residences or apartment complexes) may have "Access Control" enabled, restricting charging to Tesla vehicles only. If you encounter an issue, it's worth checking with the property management if they can adjust these settings to "Open to All."
