Charging piles are cross-platform compatible

With the rapid adoption of electric vehicles (EVs), the charging station industry is experiencing significant growth. However, the diversity of communication protocols used by different manufacturers and platforms has created challenges in ensuring interoperability between charging devices and management systems. OCPP (Open Charge Point Protocol), as an open and standardized protocol, has emerged as a critical solution for enabling seamless communication. By utilizing Shenzhen Huizhi Technology’s OCPP 4G gateway, non-OCPP protocols such as YunKuaiChong can be converted into OCPP, achieving cross-platform compatibility and unified management.

▶ Background and Significance

The Current Landscape of Multi-Protocol Systems

The EV charging industry is characterized by a variety of communication protocols, including YunKuaiChong, Teld, Weijingyun, proprietary manufacturer-specific protocols, and the internationally recognized OCPP. This lack of standardization has led to difficulties in integrating devices from different brands onto a single platform. For example, charging stations using YunKuaiChong protocols are often limited to specific platforms, complicating operations for providers managing diverse equipment portfolios.

The Role of OCPP 4G Gateway

The OCPP 4G gateway serves as a critical tool to address protocol incompatibility. It translates data and commands from non-OCPP protocols into OCPP-compliant formats, enabling seamless integration with OCPP-supported platforms. This enhances device interoperability while providing operators with greater flexibility and scalability.

▶ Technical Implementation

Overview of the OCPP 4G Gateway

The OCPP 4G gateway functions as middleware that bridges different communication protocols. It parses messages from non-OCPP systems (e.g., YunKuaiChong) and maps them to OCPP-compliant data structures. The gateway communicates with central management systems (CSMS) via WebSocket or SOAP protocols.

Supported OCPP Versions

OCPP 2.0.1: Offers advanced features like PKI encryption for enhanced security, smart charging capabilities, and support for ISO 15118.

OCPP 1.6-J: Known for its stability and widespread adoption.

Key Technical Features

  • Real-Time Responsiveness: Optimized for high-speed data processing with built-in fault tolerance to ensure stability.
  • Data Parsing and Mapping: Converts data formats from non-OCPP protocols into OCPP messages (e.g., translating a start charging command to an StartTransaction message).
  • Communication Protocols: Supports WebSocket and SOAP for seamless interaction with CSMS.
  • Security Measures: Implements TLS encryption and authentication mechanisms to ensure secure data transmission.

    ▶ Applications and Advantages

    Multi-Platform Compatibility

    The OCPP 4G gateway enables charging stations using proprietary or localized protocols (e.g., YunKuaiChong) to integrate into OCPP-compliant platforms. This facilitates unified management across different brands and systems.

    Enhanced Operational Efficiency

    • Centralized Management: Operators can manage all devices through a single platform after converting them to OCPP standards.
    • Data Standardization: Uniform data formats enable large-scale analytics for optimizing station deployment and improving utilization rates.
    • Remote Monitoring: Operators can perform diagnostics, control charging sessions, and resolve issues remotely via CSMS.

    ▶ Market Expansion

    Adopting the OCPP standard allows operators to expand into international markets where compliance with OCPP is often mandatory. This also attracts more users by providing compatibility with diverse EV brands.

    ▶ Prolonged Equipment Lifespan

    Older devices not originally designed for OCPP can be upgraded via the gateway, extending their usability while protecting prior investments.

    ▶ Conclusion

    The use of an OCPP 4G gateway is a transformative solution for overcoming protocol fragmentation in the EV charging industry. By converting non-OCPP protocols like YunKuaiChong into the widely accepted OCPP standard, operators can achieve cross-platform compatibility, streamline operations, and unlock new market opportunities. As the EV ecosystem evolves, continued advancements in gateway technology will further enhance smart charging capabilities and promote global interoperability in EV infrastructure.
