EVCC - Solar EV Charge Controller
Open source EV charge controller with a focus on solar power and smart home integration. Optimize your electric vehicle charging based on solar surplus, grid tariffs, and vehicle needs. Supports multiple EV models and wallboxes.
Project Introduction
Summary
This project is an advanced open-source charge controller designed for electric vehicles. It focuses on utilizing solar energy surplus, optimizing charging based on energy tariffs, and integrating seamlessly with existing smart home and energy management systems to provide cost-effective and sustainable EV charging.
Problem Solved
Traditional EV charging ignores local solar production or variable grid costs, leading to higher electricity bills and lower renewable energy self-sufficiency. This project solves this by intelligently managing charging to align with solar production and favorable grid conditions.
Core Features
Solar-optimized Charging
Intelligently manages EV charging to maximize self-consumption of solar energy.
Wide Compatibility
Connects to various wallboxes and EVs via supported APIs.
Smart Home & Energy System Integration
Integrates with smart home systems (e.g., Home Assistant, ioBroker) and energy meters.
Tech Stack
使用场景
This project is applicable in various scenarios where intelligent and cost-effective EV charging is desired, especially when solar power or variable tariffs are involved.
Maximizing Solar Self-Consumption
Details
Charge your EV automatically when your rooftop solar system is producing surplus energy that would otherwise be fed into the grid.
User Value
Lower electricity bills and greater utilization of your solar investment.
Charging During Off-Peak/Low Tariff Hours
Details
In areas with variable grid electricity prices, schedule charging during off-peak hours or when prices are lowest.
User Value
Minimize the cost of grid electricity used for charging.
