Ocpp-809 - Driver

Assuming you have a Linux-based gateway (Debian/Ubuntu) and an 809 board connected via /dev/ttyUSB0:

Step 1: Install the Driver Dependencies

sudo apt-get update
sudo apt-get install python3-pip libmodbus-dev
pip install ocpp modbus-tk pyserial

Step 2: Download the Vendor-Specific 809 Driver Most OEMs provide a custom script. You must configure config.json:

  "ocpp": 
    "csms_url": "wss://my.charging.cloud/ocpp/CP001",
    "charge_point_id": "809-Station-42"
  ,
  "modbus": 
    "port": "/dev/ttyUSB0",
    "baudrate": 9600,
    "slave_id": 1,
    "register_map": 
      "voltage": "30001",
      "current": "30002",
      "relay_status": "00001"

Step 3: Map OCPP Commands to Modbus Actions You must define the "Bridge Logic." For example: ocpp-809 driver

Step 4: Run the Service

sudo systemctl enable ocpp-809-driver.service
sudo systemctl start ocpp-809-driver

The Open Charge Point Protocol (OCPP) is a global communication standard used between Electric Vehicle (EV) chargers and central management systems.

Here’s a feature list for such a driver in a CSMS (Charge Point Management System) or embedded charger controller: Assuming you have a Linux-based gateway (Debian/Ubuntu) and

Issue 1: The charger goes "Offline" after 5 minutes.

Issue 2: Meter values are "0" in the cloud.

Issue 3: The driver crashes during RemoteStopTransaction. Step 2: Download the Vendor-Specific 809 Driver Most

The EV industry is shifting to OCPP 2.0.1 (which introduces ISO 15118 Plug & Charge and Device Model). Legacy 809 drivers built for 1.6 will soon be obsolete.

Look for next-gen drivers that support:
