EV Charger protocol conversion

With the rapid adoption of new energy vehicles, charging infrastructure has become a critical industry pillar. However, historical factors and diverse technical standards have led to severe “protocol fragmentation” among charging piles from different manufacturers. Shenzhen Huizhi Technology’s charging pile protocol conversion gateway addresses communication compatibility challenges between heterogeneous charging systems through these key solutions:

EV Charger protocol conversion

▶ Purpose and Importance of Charging Pile Protocol Conversion

  1. Interoperability: Enables seamless communication between charging piles, vehicles, and management platforms across brands/models.
  2. Cost Efficiency: Achieves hardware compatibility without replacing existing equipment.
  3. Function Expansion: Supports advanced features like smart charging and dynamic load management.

▶ Common Charging Protocols

  • OCPP 2.0.1: Open standard for real-time data transmission and remote control.
  • GB/T 27930: China’s national standard ensuring domestic charging infrastructure uniformity.
  • ISO/IEC 15118: International protocol enabling vehicle-to-grid (V2G) interaction.
  • Others: CHAdeMO (Japan), CCS (Europe/North America) for fast-charging scenarios.

▶ Technical Solutions for Protocol Conversion

Protocol Conversion Gateway

  • Converts charging pile data to target platform formats.
  • Supports 4G, Ethernet, RS232/RS485 communication.
  • Enables remote monitoring and fault diagnosis.

Communication Protocol Converter

  • Translates GB/T 27930 to ISO/IEC 15118 and vice versa.
  • Facilitates vehicle-to-pile communication for global market compliance.

Typical Conversion Scenarios

  • GB/T → OCPP: National standard to open protocol.
  • IEC ↔ GB/T: Bidirectional international/domestic standard conversion.
  • Proprietary → Standard: Vendor-specific protocols to industry standards.

▶ Future Development Trends

Global Compatibility: Enhanced support for emerging standards and cross-protocol optimization.

Intelligent Features: Integration of V2G capabilities and AI-driven load balancing.

Modular Design: Scalable solutions adapting to evolving charging technologies.

This framework ensures seamless connectivity across fragmented charging ecosystems while paving the way for next-generation smart grid integration.
