FAQs

  • Integration Flexibility
  • Protocol Compatibility
  • Power & Data Management
  • Software Customization
  • Scalability & Support
Integration Flexibility
  • How does the MVNO feature benefit our Fleet Management operations?
    Our mechanical engineering team works directly from your CAD drawings to customize panel dimensions, bezel profile, mounting points, and cable exit orientation. This ensures a flush, professional fit that aligns with your industrial design and simplifies assembly.
  • Is this solution suitable for both indoor and outdoor charging stations?
    The embedded panel is engineered for commercial-grade reliability in sheltered outdoor and indoor environments. With appropriate enclosure design from your side, the panel delivers consistent touch performance and visibility across typical deployment conditions.
Protocol Compatibility
  • Can the panel communicate with our charger controller and backend system using standard EV protocols?
    Yes. Pretech firmware includes pre-integrated drivers for OCPP 1.6J/2.0.1, Modbus TCP/RTU, and CAN Bus. We also support custom protocol adaptation during the ODM phase to ensure seamless data exchange between HMI, controller, and CPO platform.
Power & Data Management
  • How does the dual-port USB-C design benefit EV charging station deployments?
    One USB-C port handles dedicated power input for stable operation, while the second functions as a versatile Host/Device port for peripherals (payment terminals, printers, sensors). This separation prevents power fluctuations from disrupting data communication—a critical advantage for 24/7 charging infrastructure.
Software Customization
  • What level of OS and application customization can Pretech provide?
    We offer full-stack software adaptation: slimmed-down Android/Linux OS, custom boot animation, auto-launch of your charging application, driver integration for peripheral hardware, and OTA update framework. Our team ensures the software layer aligns precisely with your user experience and maintenance requirements.
Scalability & Support
  • How does Pretech support volume production and long-term product lifecycle?
    As an ODM partner, we manage component sourcing, production planning, and quality control to ensure supply continuity. We also offer long-term firmware maintenance and hardware revision management to support multi-year charging infrastructure projects.
