### OLED Display
To show the status, the voltage and the SOC in PEV mode, there is an OLED display connected to the serial line of the USB-to-serial-converter.
The display is programmed to receive data via serial line and show three lines. The python script is using the function self.hardwareInterface.showOnDisplay(s, strAuxInfo1, strAuxInfo2)
to fill these three lines on the display.
The display is an ESP32-powered board named "WIFI_KIT-32", available e.g. from

The arduino sketch is available at https://github.com/uhi22/SerialToOLED
The connection is simple: The 5V from the USB-to-Serial-converter board are supplying the WIFI_KIT-32, and the TXD of the USB-to-Serial-converter goes via an 1k5 protection resistor to a digital input of the WIFI_KIT_32.

### USB
Both, DieterHV and DieterLV communicate with 5V serial line with 19200 Baud. To connect these to the Laptop or Raspberry, we use a cheap USB-to-Serial converter with CP2102, similar to https://www.ebay.de/itm/122447169355?hash=item1c826b874b:g:PKYAAOSwBoVjdS28&amdata=enc%3AAQAHAAAA4IQcw6se5g1eqWsesz2sVJybly8WfWQrHcT%2BKk2kbf3dRjRl5Iimf8p54m2HcnGpjpFaTQqdKE0wrxuPJYLQcmOtofOYlAbClGhlgeIn21NQPaCGzqCSAMAI6yXqfsfCpsBZtJe1%2BfAfIOq1kEPDJBbWD6UFAv6%2FhR%2B6WxeiQKeaVSwc%2BRs87aBn0XbtWmF2p0C9RTURpWQauDpaWLsAthbiVBqBjeNkPQxMSx1AMUa33bO0OZakXjXyHVrGhEXRO7952z1oHjKyl51E0YX7Jqb5hA7GhAs%2BUGvPnBAbjKnH%7Ctkp%3ABFBMipSf-Kdh

### Q3: Is it possible to use this software in a car without CCS, to make it ready for CCS charging?
That's is definitely a goal, at it looks reachable. Of course, two aspects need to be considered:
- This project is not a final product. Further development will be necessary to ensure compatibility with chargers, and make is flexible for practical use.
- This project is not a final product. Further development will be necessary to ensure compatibility with chargers, and make it flexible for practical use.
- Some parts are not covered by this project at all, e.g. communication with the BMS, connector lock, safety considerations.
