Introduction
evcc controls Electric Vehicle (EV) charging as required to optimise for the current energy situation. A Photovoltaic (PV) system can be connected in order to charge the EV with as much self-produced energy as possible, and/or grid providers can be connected to allow for exploitation of dynamic electricity prices.
Normally, the wallbox must be compatible with the existing PV installation, often requiring equipment from the same manufacturer. However, evcc works across manufacturers and with a wide variety of wallboxes, electricity measuring devices, and PV inverters, without requiring specific manufacturer compatibility between them.
evcc is installed onto a system in the local network, so that it can communicate properly with all the necessary devices. It does this completely locally, and without any reliance on cloud connectivity (though connected components may have their own requirements). The software itself is very lean, and something like a NAS (network attached storage) or a Raspberry Pi (or similar) is completely sufficient to achieve full functionality.
Functionality
- Simple and clear User Interface
- Support for
- Plugins support a wide variety of wallboxes, meters, & vehicles over Modbus, HTTP, MQTT, JavaScript, Websockets, and Shell Scripts
- Status Notifications via Telegram, PushOver and many more
- Data Export via InfluxDB and Grafana
- Stepless regulation of charging flows with supported wall boxes (e.g the smartWB's OLC functionality)
- Rest & MQTT APIs for integration into other home automation systems (such as Home Assistant)
Requirements
evcc requires at least the following:
- a supported Wallbox or Switchable Socket
- a supported Energy Meter at the house connection, or alternatively a supported PV inverter / other metering device that can measure current energy production
- a supported system to run evcc on!
Optionally:
- one or more supported Vehicles to collect charge status / level information
- additional supported Wallboxes or Switchable Sockets
- supported PV inverter(s)
- supported Battery Storage System(s)
- a supported Energy Management System (such as SMA Sunny Home Manager)
- information on a dynamic electricity tariff
evcc comes without any kind of guarantee, and you use the software at your own risk. It is your responsibility to use evcc responsibly - it's your house fire!
