I. Differences Between Chinese GB/T and Overseas Charging Standards
Core Features of Chinese GB/T (GB/T 20234)
Interface Design:
AC charging guns feature a “7-pin” structure (L1/L2/L3 live wires, N neutral wire, PE ground wire, CC/CP control signals).
DC charging guns have a “9-pin” design (including high-current DC+/DC- terminals and communication lines).
Safety Features:
Compared to European standards, GB/T includes additional protective designs such as mechanical locks and micro switches.
Supports single-phase 220V (7kW) and three-phase 380V (40kW) AC charging, with DC fast charging power reaching up to 250kW (1000V/250A).
Compatibility Limitations:
The GB/T interface is incompatible with European (Type 2), American (SAE J1772), and Japanese (CHAdeMO) standards. Directly plugging into overseas charging stations will result in physical interface mismatches and communication protocol errors.
Analysis of Main Charging Standards in Overseas Markets
Central Asia and Russia:
AC Charging: Central Asia and Russia primarily adopt the European IEC 62196 Type 2 standard (Mennekes interface), a 7-pin AC interface supporting single-phase (230V) and three-phase (400V) charging, with a maximum current of 32A or 63A and a power range of 7kW to 43kW.
DC Charging: DC fast charging mainly uses CCS2 (Combined Charging System 2), which adds two high-current DC terminals (DC+/DC-) to the Type 2 interface, supporting up to 350kW charging power.
Grid Characteristics: The grid voltage in Central Asia and Russia aligns with European standards, with single-phase voltage at 220-230V and three-phase voltage at 380-400V, largely compatible with China’s GB/T voltage range (220V single-phase/380V three-phase), but with differences in interface design and communication protocols.
Middle East and North Africa:
AC Charging: The Middle East (e.g., UAE, Saudi Arabia) primarily uses the European Type 2 interface, while some regions (e.g., Egypt) are compatible with the American SAE J1772 interface. North African countries (e.g., Morocco, Tunisia) mainly use Type 2, with some areas using the British BS 1363 plug.
DC Charging: DC fast charging in the Middle East and North Africa is predominantly CCS2, with some regions (e.g., Egypt, Morocco) compatible with the CHAdeMO standard.
Grid Characteristics: The grid voltage in the Middle East and North Africa is similar to Europe, with single-phase voltage at 220-230V and three-phase voltage at 380-400V. However, voltage fluctuations may occur in some areas (e.g., Saudi Arabia), requiring attention to the voltage adaptability of charging equipment.
II. Essential Conversion Solutions for GB/T to Overseas Charging Interfaces
Physical Interface Adapters
European (Type 2) to GB/T Adapter:
Interface Design: The European Type 2 interface has a 7-pin design (L1/L2/L3/N/PE/CC/CP), similar in physical form to the GB/T 20234 7-pin interface but differing in pin positions, locking mechanisms, and signal definitions.
The adapter must include a signal conversion module to translate Type 2 CC/CP control signals into GB/T CC/CP signals, ensuring compatibility between the vehicle and charging station communication protocols.
Technical Parameters: Supports single-phase (230V/32A) and three-phase (400V/32A or 63A) charging, with a maximum power of 43kW (AC).
The adapter must feature overcurrent protection, over-temperature protection, and short-circuit protection to ensure charging safety.
Applicable Regions: Suitable for countries using Type 2 interfaces, such as Russia, Kazakhstan, and Turkey, covering most AC charging scenarios.
American (SAE J1772) to GB/T Adapter:
Interface Design: The American SAE J1772 interface has a 5-pin design (L1/N/PE/CC/CP), incompatible with GB/T in both physical form and signal definitions.
The adapter must include an impedance matching circuit to address voltage differences between American (110-120V) and GB/T (220V) standards, while converting CC/CP signals.
Technical Parameters: Supports single-phase charging (120V/16A or 240V/32A), with a maximum power of 7.2kW (120V) or 19.2kW (240V).
The adapter should be equipped with a step-up transformer to support low-voltage (110-120V) regions.
Applicable Regions: Suitable for SAE J1772 charging stations in parts of the Middle East (e.g., UAE, Egypt) and North Africa (e.g., Morocco).
DC Fast Charging Adapter (CCS2 to GB/T):
Interface Design: The CCS2 interface adds two high-current DC terminals (DC+/DC-) to the Type 2 base, incompatible with the GB/T DC interface (9-pin design) in both physical form and signal definitions.
The adapter must include a CAN bus communication module to translate between ISO 15118 (European) and GB/T 27930 (Chinese) protocols.
Technical Parameters: Supports a maximum DC output of 1000V/500A, with a peak power of 350kW.
The adapter requires a liquid cooling system to manage heat during high-power charging.
Applicable Regions: Suitable for CCS2 DC fast charging stations in Russia, Central Asia, the Middle East, and North Africa, covering most DC charging scenarios.
CHAdeMO to GB/T Adapter:
Interface Design: The CHAdeMO interface has a circular design, incompatible with the GB/T DC interface in both physical form and signal definitions.
The adapter must include a dedicated communication module to translate between CHAdeMO 2.0 and GB/T 27930 protocols.
Technical Parameters: Supports a maximum DC output of 500V/125A, with a peak power of 62.5kW.
The adapter must feature high-temperature protection and overcurrent protection.
Applicable Regions: Suitable for CHAdeMO charging stations in parts of North Africa (e.g., Egypt, Morocco).
DC Fast Charging Compatibility Enhancements
CCS2 to GB/T DC: For regions using CCS2 DC stations (e.g., Europe and the Middle East), custom converters with CAN bus communication protocols are required to support ISO 15118 and GB/T 27930 protocol translation.
CHAdeMO to GB/T: For regions covered by Japanese standards (e.g., parts of North Africa), dedicated converters must be configured to match CHAdeMO 2.0’s 500V/125A DC output parameters.
Key Technologies and Certification Requirements
Safety Certifications: Converters must obtain local certifications such as CE (Europe), GOST-R (Russia), and SASO (Saudi Arabia), ensuring insulation ratings (IP67) and fire-resistant materials (PC+ABS) comply with target market regulations.
Power Matching: Select converter specifications (e.g., 32A/63A AC or 200A DC) based on vehicle battery capacity to avoid overheating due to overloading.
