evcc is open-source software for intelligent energy management that serves to synchronize the charging process of electric vehicles (EV) and the demand of other controllable consumers with the user's own energy generation system (e.g., PV system). It optimizes the charging process by utilizing surpluses from the photovoltaic system and electricity from dynamic tariffs to reduce costs and increase self-consumption. Special features include cross-manufacturer compatibility, local execution without cloud dependency, and a modular, customizable architecture that enables intelligent control of wallboxes, heat generators, PV systems, electricity meters, and battery storage systems.
