GB/T to CCS1 adapter

Product Description

This adapter is a DC fast charging converter developed by Electway, designed to solve the compatibility issue between GB/T charging stations in China and CCS1 standard electric vehicles (common in North America and South Korea). As more CCS1‑compliant EVs enter the Chinese market or travel internationally, the need for a reliable GB/T‑to‑CCS1 solution has grown significantly. Our adapter enables CCS1 vehicles to charge directly at GB/T DC fast‑charging stations across China, effectively bridging the gap between the two standards.

With a rated power of 120kW, a rated current of 250A DC (maximum 350A), and a voltage range up to 1000V DC, it delivers efficient and reliable fast charging while remaining compact and durable. The adapter features an IP55 protection rating (in coupled state) and operates from -20°C to +45°C, ensuring dependable performance in most weather conditions. It is plug‑and‑play, requires no vehicle modification, and is compatible with all major GB/T charging networks (State Grid, TELD, Star Charge, etc.) and all CCS1 vehicles that comply with DIN70121 / ISO15118 protocols. Built to Chinese national standards (GB/T 20234.3-2015 and GB/T 27930-2015) and backed by Electway‘s manufacturing expertise, the adapter delivers reliable protocol conversion, electrical safety, and long‑term durability.

Key Advantages

Solve Charging Incompatibility in China: Drive your CCS1 EV (SAE J1772 Combo 1) and charge at any GB/T DC fast‑charging station across Mainland China. No more “charger not matching” frustration.

Protect Your Battery and Vehicle: Rigorously tested design ensures pure protocol conversion without interfering with vehicle charging systems.

Precise Protocol Conversion: Seamlessly translates GB/T communication protocols (GB/T 27930) to CCS1 (DIN 70121 / ISO 15118), enabling smooth and stable charging sessions. Note: Does not support older GB/T 2011 versions (24V, 500V piles).

Safe and Reliable: IP55‑rated protection keeps out dust and withstands low‑pressure water jets, while rugged construction ensures safe operation in outdoor environments.

Maximum Infrastructure Utilization: Instantly makes China‘s vast GB/T charging network accessible to CCS1 electric vehicles without requiring any infrastructure upgrades – ideal for charging station operators and individual owners.

Main Applications

Foreign EV Owners in China: If you drive a CCS1‑compliant electric vehicle (e.g., Tesla Model 3/Y North American spec, Ford Mustang Mach‑E, Chevrolet Bolt, Hyundai Ioniq 5/6, Kia EV6, etc.) in Mainland China, this adapter lets you charge at tens of thousands of GB/T DC fast‑charging stations – perfect for daily driving and cross‑region travel.

Fleet & Commercial Operations: Logistics and ride‑hailing companies operating mixed‑standard fleets can use this adapter to charge CCS1 vehicles at existing GB/T charging facilities, avoiding costly infrastructure retrofits.

Charging Infrastructure Providers: Expand your charging station‘s service coverage to accommodate the growing number of imported CCS1 vehicles in China, increasing station utilization and revenue without hardware upgrades.
