Pazzk EVSE is an open-source project designed to provide a reliable and scalable electric vehicle charging solution. It complies with various EV charging standards while maintaining a hardware-independent architecture to enable seamless integration across different environments.

This project is available under both the GPLv3 open-source license and a commercial license. The open-source version is free to use, while the commercial license includes additional features and support services.

In addition to our own reference board, we actively support migration to existing commercial products and custom hardware.

Warning

Pazzk EVSE firmware directly controls electrical and electronic components.
Incorrect configuration or installation may cause safety hazards. Ensure compliance with electrical safety regulations and certifications before deployment.

Key Features

• Supports various charging methods:
  • Backend authentication (OCPP-based)
  • Vehicle automatic authentication (ISO 15118-based)
  • Unauthenticated charging
• Enhanced safety features:
  • GFCI and relay stuck detection
  • Input and output power monitoring
• Modular architecture:
  • Components can be added or removed based on requirements
    • Example: Audio, LCD display, RFID reader, etc.
• Network capabilities:
  • Supports Ethernet, Wi-Fi, and BLE (Bluetooth Low Energy)
  • Automatic connection recovery and management
• Flexible platform support:
  • Compatible with various MCUs and host platforms
  • Can be used as a host simulator
• Reference hardware:
  • Open-source hardware available (separate repository)
