GB/T EV DC Charging Cable — Specification (80A–375A)

1) Product Overview

The GB/T DC charging cable assembly is engineered for DC fast charging systems using the GB/T standard (commonly GB/T 20234.3 interface). It supports a wide current range 80A to 375A, suitable for public fast chargers, fleet depots, bus/truck charging, and mobile DC charging equipment. OEM/ODM customization is available for cable length, branding, and cooling configuration.

2) Electrical Specifications

• Connector Standard (Vehicle Side): GB/T DC (GB/T 20234.3)

• Charging Type: DC fast charging cable assembly

• Rated Current Range: 80A–375A (model selection)

• Common ratings: 80A / 100A / 125A / 150A / 200A / 250A / 300A / 350A / 375A

• Rated Voltage: Up to 1000 V DC (typical for DCFC; configurable by design)

• Insulation Resistance: ≥ 1000 MΩ (typical)

• Withstanding Voltage (Hi-Pot): 2500–3000 V AC (typical; per design)

• Signal/Control Cores: Integrated control and communication lines as required by GB/T charging system

3) Cable & Mechanical

• Standard Cable Length: 5 m (industry common)

• OEM Length Options: 3 m / 4 m / 6 m / 7 m / 10 m (custom available)

• Conductor Material: High-purity copper

• Outer Jacket Material: TPU (standard) / TPE (optional)

• Cable Color: Black (custom colors optional)

• Strain Relief: Reinforced anti-bending design for high-duty operation

• Typical Plug Insertion Cycles: ≥ 10,000 cycles (typical; depends on final connector spec)

4) Cooling Options (Select by Current Requirement)

A) Air-Cooled (Standard)

• Recommended for 80A–250A continuous applications

• Lower cost and simpler maintenance

B) Liquid-Cooled (Optional)

• Recommended for 300A–375A high-duty cycle or continuous high-current applications

• Improved thermal performance and cable handling at high current

(Final current rating depends on cable cross-section, cooling method, ambient temperature, and duty cycle.)

5) Environmental & Protection

• Operating Temperature: -30°C to +50°C (typical; configurable)

• Ingress Protection: Plug typically IP54/IP55 when mated (model-dependent)

• UV Resistance: Outdoor-grade jacket option available

• Flame Retardant: Available (market requirement dependent)

6) Compliance & Quality Control

• Standards Reference:

• GB/T 20234 (DC connector interface)

• GB/T 18487 / IEC 61851 (charging system requirements, application dependent)

• Factory Testing (Typical):

• Continuity test

• Insulation resistance test

• Hi-pot test

• Connector function and lock verification

7) OEM/ODM Customization

• Current rating selection (80A–375A)

• Cable length, jacket material (TPU/TPE), and print marking

• Connector housing color & logo branding

• Liquid-cooling interface configuration (if applicable)

• Packaging: branded carton / bulk shipment / retail box

8) Typical Applications

• Public DC fast chargers (CPO networks)

• Fleet depots and logistics centers

• Electric buses and heavy-duty EV charging

• Mobile DC chargers / battery-integrated fast chargers
