⚡ChargePi is an open-source Raspberry Pi 4 based ⚡Charging Point🔌 project, which supports multiple EVSEs and simple connectors🔌. You can also add an RFID/NFC reader and a display to the Charging Point. It is configurable, simple to make and uses off-the-shelf hardware.
A connector🔌 consists of an indicator (🚥 RGB LED strip), a relay and a ⚡ power meter. The client is written in Go and requires installation of a few C libraries.
ChargePi-go client can be deployed/run in multiple ways:
- standalone
- Docker 🐳 by building the image and running the container
- Docker-compose with SteVe Central System and Watchtower (recommended for testing only)
- Docker-compose (client only)
