How to Use a CCS2 to GBT Adapter: A Complete Guide for EV Owners & Businesses

Introduction

If you have imported a high-tech electric vehicle from China—whether it’s a BYD, Li Auto, Zeekr, or NIO—you know the struggle. You have a fantastic car, but you are driving in a region dominated by CCS2 charging infrastructure (such as Europe, Southeast Asia, Australia, or parts of South America).

The "Port Mismatch" is the biggest hurdle for parallel import EV owners. Your car speaks GB/T (the Chinese standard), but the local fast chargers speak CCS2.

The good news? You don't need to swap your car’s charging port or buy a dedicated GB/T charger. You simply need a high-quality CCS2 to GB/T Adapter, which connects to the standard CCS2 charging connector. This instantly grants you access to all standard CCS2 stations in your area. Better yet, with its built-in anti-theft lock, you can charge freely and securely without worrying about your adapter going missing. In this guide, we will explains how these devices work, how to use them safely, and how to troubleshoot common issues to ensure you’re never left stranded.

Understanding the Tech: Why It’s Not Just "A Simple Plug"

Before we get to the "how-to," it is important to understand what this adapter actually does. It is not just a piece of plastic that changes the shape of the connector; it is a sophisticated computer.

• The Language Barrier: European/Global CCS2 chargers use PLC (Power Line Communication). Chinese GB/T cars use CAN bus communication. They speak completely different languages.

• The Solution: An active CCS2 to GB/T adapter contains a microprocessor. It acts as a real-time translator, converting the CCS2 protocols into GB/T signals so your car’s Battery Management System (BMS) can "shake hands" with the charger.

Note: This is why reliable adapters are heavier and more expensive than simple AC plugs—they are packed with electronics.

How to Use a CCS2 to GB/T Adapter (Step-by-Step)

Getting your adapter hooked up is easy, but you really have to mind the order. Since the adapter needs a quick start (it has to power up its internal chip to translate the charging signals), doing the steps in the right sequence is key to avoiding those frustrating connection errors.

1. Initial Setup: Installing the 18650 Battery

Before using your Xteck adapter for the first time, you must install the power source that drives the smart protocol conversion chip.

①　Finding the battery spot：First, find the battery access hatch located on the main body of the adapter.

②　Open Carefully: Grab that tiny screwdriver we included in the box. Take out the screws and gently lift the lid off.

• Crucial Note: There is a thin wire connecting the lid to the internal board. Don’t go ripping it off or pulling too hard, otherwise you’ll snap that connection and ruin the unit.

③　Insert the 18650 Battery: Pop a standard 18650 lithium battery into the slot.

• ！WARNING: Make sure the plus (+) side is pointing UP. If you put the battery in backwards, you’re going to cause a short circuit and likely fry the adapter’s electronics for good.

④　Seal and Test: Screw the cover back on firmly. Press and hold the Power Button on the handle for 2 seconds. A flashing red light confirms the adapter is powered on and ready.

2. How to Use: The Correct Charging Sequence

To ensure a successful "handshake" between the CCS2 station and your GB/T vehicle, please follow this specific order:

• Step 1: Connect to the Vehicle (GB/T) Plug the Xteck adapter directly into your car’s GB/T DC charging port. Ensure it is seated firmly.

• Step 2: Connect the Power Source (CCS2) Take the CCS2 charging gun from the station and plug it into the female port of the adapter.

• Step 3: Initiate the Handshake Press the Power Button on the adapter handle until the red light starts flashing. The adapter is now translating the CCS2 (PLC) signal to the GB/T (CAN) signal. You can now start the charging session on the station’s screen or app.

• Step 4: Monitoring The flashing light indicates active communication. Your vehicle's dashboard should now show the charging status and real-time power intake.
  

  
  

  
  

3.Ending the Session the Right Way

Whatever you do, don't just yank the adapter out while it’s still live. "Hot-unplugging" can seriously glitch your car's battery management system (BMS) or cause electrical arcing. To keep your electronics safe, just stick to this order:

①　Kill the power first: Keep your finger on the adapter's Power Button until that red light goes completely dark. This tells the internal chip to stop the data translation.

②　Unplug the charging gun: Once the power is off, you can pull the heavy CCS2 cable out of the back of the adapter.

③　Disconnect from the car: Now it’s safe to remove the adapter from your vehicle's GB/T socket.

④　Pack it away: Toss the adapter back in its protective case. Try to keep it in a cool, dry spot in your trunk so it’s ready for your next stop.

Compatibility Considerations

Not all cars and stations are created equal. Here is what you need to know about compatibility.

Vehicle Compatibility (GB/T DC Port)

These adapters are designed for domestic Chinese EVs (parallel imports/grey market) that retain the GB/T charging port. Common compatible brands include:

• BYD (Han, Tang, Yuan, Seal - Chinese Specs)

• Li Auto (Lixiang) (L7, L8, L9, Mega)

• Zeekr (001, 009, X)

• NIO, XPeng, Avatar, HiPhi

• Tesla (Chinese Grid versions exported privately)

  
  

Station Compatibility

• Supported: All standard DC Fast Chargers (CCS2). This includes networks like Ionity, Shell Recharge, and BP Pulse, xteckpower.

• Tesla Superchargers: Yes, you can use these, provided the station has CCS2 cables and is open to non-Tesla cars.

(Just so you know: If you happen to drive a Tesla as well, we’ve got you covered. Xteck makes a separate line of adapters designed specifically for Tesla ports.)

• NOT Supported: AC Chargers. This adapter is for DC Fast Charging only. Do not try to use it with a Type 2 home wallbox.

Safety Tips When Using a CCS2 to GB/T Adapter

High-power charging involves high voltage and high current. Safety is non-negotiable.

• Manage the Weight: CCS2 cables are notoriously heavy and stiff. When you plug the assembly into your car, the weight can stress your car’s plastic charging socket. Tip: Hold the cable weight with your hand until the lock engages, or use a knee/stand to support it if the cable is very short.

• Avoid the "Hot Unplug": Never force the adapter out while the car is charging. Always stop the session digitally first. Breaking the circuit physically can cause dangerous electrical arcing.

• Temperature Watch: High-speed protocol translation generates heat. Ensure the adapter is not covered by rags or exposed to direct scorching sunlight for hours if possible.

• Moisture Control: While Xteck adapters are rated IP55 or higher, avoid using them if the connection points are submerged in water or during torrential storms where water could enter the interface.

Common Problems & How to Solve Them

Problem: "Communication Error" or Charger Won't Start

• Cause: The "Handshake" timed out.

• Solution: Unplug everything. Wait 60 seconds for the adapter's internal chip to reset. Re-connect following the strict sequence: Gun first, then Car.

Problem: Charging Speed is Slow

• Cause: This could be a station limitation, or your battery is cold/full.

• Solution: Check the station's rating. Also, remember that the adapter acts as a pass-through; it cannot force a 60kW station to give you 120kW.

Problem: Adapter is Stuck in the Car

• Cause: The locking pin hasn't retracted.

• Solution: Do not force it. Press the "Unlock" button on your car key or inside the dashboard. If that fails, look for the emergency manual release cable in your trunk (refer to your car manual).|

How to Choose a Good Adapter (Buyer’s Guide)

Since this device manages the power flow to your expensive EV battery, quality is critical. Here is what to look for:

1. Amperage Rating: Look for adapters rated for 150A, 200A, 250A, or 300A. A higher rating means faster charging and better heat management. (Xteck adapters are engineered to support up to 300A, ensuring you can access the maximum possible speed from high-power charging stations.)

2. Firmware Upgradability: EV manufacturers (like BYD or Zeekr) frequently update their car software (OTA). A good adapter (like Xteck’s) usually has a USB port to update its firmware so it remains compatible with new car software.

3. Safety Certifications: Ensure the product uses flame-retardant materials and has CE/RoHS compliance.

4. Metal Pin Quality: Look for silver-plated copper alloy pins for maximum conductivity and minimal resistance.

FAQ

Q: Does using this adapter void my vehicle warranty?
A: Generally, no, provided you use a certified, high-quality adapter. However, always check with your specific importer or dealer.

Q: Can I use this in the rain?
A: Quality adapters are designed for outdoor use and typically carry an IP rating for protection against splashing water (e.g., IP54). Light rain is generally acceptable. However, for maximum safety and to prevent potential short circuits or charging interruptions, we strongly advise against using the adapter during heavy downpours or thunderstorms. Always ensure the connection surfaces are as dry as possible before plugging in.

Q: Why does the charging stop at 95%?
A: This is usually a setting in your vehicle's BMS to protect the battery health, not a fault of the adapter.
