About Evcc

evcc is an extensible electric vehicle charge controller and home energy management system. Its stated goal is local energy management that does not rely on cloud services, and its tagline is solar charging, meaning it steers car charging toward surplus photovoltaic power.

It supports a very wide list of EV chargers from many brands, as well as the EEBus and OCPP protocols, do-it-yourself chargers, smart switches, and heat pumps and electric heaters. It also reads energy meters, including solar inverters and battery systems. Repository topics mention MQTT, Modbus, SunSpec and wallboxes, and the project provides a simple, clean user interface.

evcc is written in Go and licensed under MIT. It runs on your own hardware and was featured in PV Magazine and c't Magazin according to its README. The project suits homeowners with solar panels, a wallbox and an electric car who want automated charging decisions.
