Open Source Smart EV Charging with Solar PV integration. Optimize your electric vehicle charging to maximize solar energy usage and minimize grid costs.
This project is an advanced open-source solution for smart charging of electric vehicles. It focuses on integrating with residential solar PV systems to ensure EVs are charged cleanly and cost-effectively, prioritizing the use of locally generated renewable energy.
Electric vehicle charging can be expensive and may draw heavily from the grid, potentially at peak times. This project solves the problem of inefficient charging by enabling users to charge their EVs using excess solar energy or during off-peak grid tariff periods, reducing electricity bills and maximizing solar self-consumption.
Dynamically adjusts charging power based on real-time solar PV production and grid load/prices.
Supports integration with a wide range of EV chargers, cars, and energy meters via various protocols (Modbus, MQTT, API, etc.).
Provides a user-friendly web interface and API for monitoring and controlling charging sessions.
evcc can be applied in various scenarios where intelligent and cost-aware EV charging is desired:
Configure evcc to only charge the EV when surplus solar energy is available, effectively using 100% solar power for mobility.
Achieve zero-cost, emission-free charging using your own solar power, reducing grid dependence.
Integrate grid tariff data to charge the EV primarily during off-peak hours, minimizing electricity costs.
Significantly lower electricity bills by leveraging favorable grid tariff structures.
Prioritize grid power during emergencies or when solar is insufficient, ensuring the car is ready when needed, while still optimizing for cost or carbon footprint.
Balancing renewable energy use with practical charging needs and availability.
