Have you ever been on a road trip in your GM EV, only to find yourself anxiously scanning for compatible charging stations? Or perhaps you've heard about the convenience of Tesla's vast Supercharger network and wished your vehicle could tap into it? Well, the good news is that your GM electric vehicle can now access the Tesla Supercharger network, significantly expanding your charging options and making EV ownership even more convenient! This comprehensive guide will walk you through everything you need to know, step-by-step. Let's get started!
Step 1: Understanding the North American Charging Standard (NACS) and Your GM EV
Before you hit the road, it's essential to understand the technology enabling this charging compatibility. Tesla developed the North American Charging Standard (NACS), which has become a widely adopted standard for EV charging in North America. Previously, GM EVs primarily used the Combined Charging System (CCS1) connector for DC fast charging.
The key to unlocking the Tesla Supercharger network for your current GM EV is a NACS DC adapter. This adapter acts as a bridge, allowing your GM's CCS1 port to connect seamlessly with the NACS cables at Tesla Superchargers. While newer GM models (starting with some 2026 models like the Cadillac OPTIQ) will likely come with native NACS ports, if you own a current GM EV, an adapter is your essential tool.

1.1: Why the Adapter is Crucial
The NACS DC adapter is specifically designed to handle the high power delivery of Tesla Superchargers while ensuring compatibility and safety with your GM EV's battery. GM strongly advises using a GM-approved NACS DC adapter to protect your vehicle's battery and maintain your warranty. While third-party adapters exist, using a non-approved adapter could potentially damage your EV's battery and void portions of your vehicle's limited warranty.
Step 2: Acquiring Your GM-Approved NACS DC Adapter ️
This is your first tangible step toward Supercharger access! You have a few convenient ways to purchase the necessary adapter.
2.1: Where to Buy Your Adapter
Through Your GM Mobile App: This is often the most straightforward method. Open your myChevrolet, myGMC, or myCadillac mobile app. Navigate to the "Public Charging" section, then look for the "Tesla Supercharger" option. You'll likely see a prompt to "Order Adapter." Follow the instructions, which will typically involve inputting your EV's VIN and selecting a delivery option (ship to your home or pick up at a local dealership).
GM Accessories Websites: You can also find the NACS DC adapter on the official Chevrolet Accessories, GMC Accessories, or Cadillac Accessories websites. Search for "NACS DC Adapter" or "Tesla Supercharger Adapter."
Your Local Dealership: If you prefer an in-person purchase or have questions, your local GM dealership can assist you in acquiring the approved adapter.
The adapter typically costs around $225 USD. If you're enrolled in My GM Rewards, you might even be able to apply points towards its purchase or earn points from it.

Step 3: Setting Up Your GM Mobile App for Supercharging
Your GM vehicle's mobile app is central to the Supercharging experience. It acts as your interface for finding chargers, initiating sessions, and managing payments.
3.1: Activating Tesla Supercharger Access
Open Your App: Launch your myChevrolet, myGMC, or myCadillac mobile app.
Navigate to Public Charging: From the app's home screen, go to the "Settings" section and select "Public Charging."
Activate Tesla Supercharger: In the Public Charging screen, look for the "Tesla Supercharger" option and select the blue "Activate" text next to it.
Enroll and Add Payment: Press "start" and follow the prompts to enter your credit card information. Press "Activate" again to enroll in GM Tesla Charging. This process allows you to seamlessly pay for future charging sessions with no monthly fee.
3.2: Finding Tesla Superchargers in Your App
Once activated, your app will be your guide to the Supercharger network.
Go to the Map Tab: Navigate to the "Map" tab within your GM mobile app.
Search for Tesla Superchargers: Use the map's search bar to look for "Tesla public charging station" or similar.
Filter for NACS (if applicable in Google Built-in): If your vehicle has Google built-in, you can also filter charging stations on your center display. From the map screen, select the "Charging Stations" icon. In the list, select the "Filter" icon, then "Compatible Plugs," and toggle "NACS" to "On." This will show NACS-compatible stations in your search results and EV trip plans.
Step 4: Charging Your GM EV at a Tesla Supercharger
Now for the main event – plugging in and powering up!
4.1: The Charging Process
Locate and Navigate: Use your GM mobile app to find an available Tesla Supercharger station and navigate to it.
Arrive and Select Charger: When you arrive, select your specific charger in the app.
Prepare Your Vehicle: Exit your vehicle and open your charging port door. If it's a DC fast charger, remember to pull out the small cap covering the lower portion of the port.
Connect the Adapter and Cable: First, connect the Tesla Supercharger cable to your NACS DC adapter. Ensure it clicks securely into place.
Plug into Your Vehicle: Now, plug the adapter (with the Tesla cable attached) into your GM EV's CCS1 charging port. You'll feel a click when it's secure.
Start Charging in the App: Tap the "Start Charging" button in your GM mobile app. Within a few seconds, charging should begin automatically.
Monitor Your Session: You can monitor your charging progress directly within the app.
4.2: Ending Your Charging Session
QuickTip: Treat each section as a mini-guide.
Stop Charging in the App: When you're ready to leave, or your charging session is complete, stop the session via your GM mobile app.
Remove Cable and Adapter: Remove the charging cable and the NACS DC adapter as one unit from your vehicle.
Separate Adapter: Click the latch on the adapter to remove it from the Tesla cable.
Close Port: Close your vehicle's charge port door. (Your vehicle might beep if you forget!)
Return Cable: Return the Tesla charging cable to its pedestal.
Step 5: Understanding Pricing and Best Practices
While access is convenient, it's good to be aware of pricing and charging etiquette.
5.1: Pricing for Non-Tesla EVs
Variable Rates: The cost of using a Tesla Supercharger for non-Tesla EVs can vary by location and demand. Prices are typically displayed in the Tesla app (which your GM app integrates with for payment).
Membership Option: Tesla offers a Supercharging membership which provides reduced rates per kWh. Non-members will generally pay a higher per-kWh rate.
Idle Fees: Be mindful of "idle fees." These are charged if your vehicle remains connected to a Supercharger stall after it's fully charged, especially when the station is 50% capacity or more. These fees can double if the station is 100% occupied. It's good practice to move your car once your charging session is complete to free up the stall for others.
5.2: Supercharging Etiquette
Charge to 80%: For DC fast charging, it's generally recommended to charge only to 80% capacity. Charging beyond 80% significantly slows down the charging rate, making it inefficient for both you and others waiting. If you need a full charge, consider moving to a Level 2 charger for the final top-up.
Don't Occupy Unnecessarily: Only park in a Supercharger spot when actively charging. Once you're done, move your vehicle.
Shared Power: Some Superchargers share power between stalls. If possible, try to choose a stall that isn't directly sharing power with an occupied adjacent stall to maximize your charging speed, though 175kW is still plenty for many EVs.
Never Unplug Someone Else's Car: This is a golden rule of public charging.
By following these steps and tips, you can confidently and conveniently use the Tesla Supercharger network to power your GM EV, making your electric adventures more seamless than ever!
