## What it is
evcc is an open-source EV charge controller and home energy management system written in Go, designed to run locally without cloud dependencies. It manages EV chargers, heat pumps, home batteries, and solar PV surplus charging with a web UI and companion mobile apps.

## Use cases
- charge my EV using solar surplus automatically
- control my wallbox from any manufacturer locally
- optimize charging with dynamic electricity tariffs like Tibber or aWATTar
- coordinate home battery and EV charging priorities
- manage load across multiple charge points
- charge my heat pump with cheap or green electricity
- schedule charging to finish by departure time

## When to choose
- you have a PV system and want to charge your EV with solar surplus
- you want local, privacy-friendly energy management without cloud reliance
- you need broad charger/meter/inverter compatibility including OCPP and EEBus
- you want dynamic tariff or CO2-optimized charging plans

## When to avoid
- you need a fully managed cloud service with remote access out of the box
- your hardware is not among the supported chargers, meters, or vehicles
- you only need simple time-based charging without energy management
