ChargePi is an open-source, Linux based ⚡Charging Point🔌 "framework". It makes your EV charging station smart by abstracting and unifying the hardware components into a customizable, modular Charge Point with OCPP 1.6 and 2.0.1 support, an intuitive UI for easy management and an API for custom integrations. It is highly customizable, simple to make and supports both off-the-shelf and commercial hardware.
A charge point is a device, consisting of multiple EVSEs, that is capable of delivering energy to an electric vehicle. Each EVSE has a connector, an EV Charge Controller and a Power Meter. Optionally, the charge point can have an RFID/NFC reader as an authentication mechanism, a display as a user interface, a status indicator and a communication module for connecting to the backend.

- OCPP 1.6 - ChargePi supports OCPP 1.6, the most common protocol for EV charging stations. OCPP 2.0.1 support is planned.
- Easily configurable - ChargePi is easy to configure and customize. It comes with default settings that require minimal configuration.
- Easy replication - ChargePi is easy to replicate. It can be deployed on a Raspberry Pi or any other Linux-based device. Configurations can be easily exported from an existing device to other devices.
- Hardware-agnostic - ChargePi supports a variety of hardware components. You can mix and match the hardware components to create a charging station that suits your needs.
- API - ChargePi comes with an API that allows you to integrate it with other systems.
- OCPP 1.6 Extension - Security extension for OCPP 1.6, which adds additional security features to the protocol.
- OCPP 2.0.1 Support - Support for OCPP 2.0.1, the latest version of the OCPP protocol.
- Simulator - ChargePi offers a simulator mode, which allows you to simulate events such as charging, stopping charging, and RFID authentication. Mostly used for testing purposes.
- Demo mode - a functional charging station that can be used for demonstration purposes, runs with emulated hardware.
- Smart charging - Smart charging functionality, which allows you to optimize the charging process based on factors such as energy prices, grid load, and user preferences.
- Customizable UI - ChargePi comes with a customizable UI that allows you to easily manage your charging station.
All contributions for hardware support are welcome. If you want to add support for a new hardware component, please check out the hardware support guide. The more hardware is supported, the more customizable the ChargePi is.

Choose the desired functionality and hardware.
-
Wire your hardware according to the provided schematics (if the hardware is supported - otherwise, seek professional guidance or contribute to the project!).
[!CAUTION] The hardware part of the project requires fairly good electrical knowledge. Make at your own risk or seek professional guidance. The project is not responsible for any damage caused by the hardware and will not take responsibility for any software misconfiguration or misbehavior.
-
Configure the settings files according to the hardware and desired functionality:
-
Run the client. ChargePi-go can be deployed/run in multiple ways:
- standalone (host machine)
- Docker 🐳 and docker-compose
Details on how to run the client on are described in the client startup guide.
To configure the ChargePi, check out the configuration guide. Client comes with default settings which require minimal configuration.
