evcc.io Information

evcc is an open source energy management system that optimizes electric vehicle charging using solar energy and dynamic electricity prices. Our community-driven software intelligently controls EV chargers, heat pumps, and smart plugs to maximize self-consumption of solar power, reducing costs and increasing energy independence. The system communicates with solar inverters, home batteries, vehicles, and chargers from all major manufacturers - no vendor lock-in, no cloud dependencies, your data stays private. Key features: - Automatic solar surplus charging - starts and adjusts charging based on available solar production - Heat pump control for optimal solar usage and grid pricing - Dynamic tariff optimization - operates devices when grid electricity is cheapest and greenest - Multi-vehicle and multi-charger support with load management - Home battery integration and control - Extensive device compatibility (250+ supported devices) - Smart home integrations (Home Assistant, openHAB, ioBroker) - Modern, responsive web interface evcc runs on minimal hardware like Raspberry Pi or Docker containers. Used by homeowners with solar installations, electricians, solar installers, and energy enthusiasts worldwide. Join our community contributing to the energy transition. The project is actively maintained by a dedicated team and supported by a global network of contributors.
