Open source firmware stack for standards-compliant, interoperable, and secure EV charging.
EVerest is the open source firmware stack for EV charging stations. By digitally abstracting the complexity of multiple standards and use cases, EVerest runs on any device, from unmanaged AC home chargers to complex multi-EVSE satellite public DC charging stations with battery and solar support. EVerest supports all the standards and protocols needed for standards-compliant, interoperable and secure charging. In other words, EVerest does the hard work of translating standards into working code to ensure that every car works with every charger with every charging app and network.

EVerest in the charging system context
EVerest is able to manage communication between different players:
- Car
- Local energy generation & batteries Adjacent chargers (WIP)
- Grid (including specific grid constraints)
- Cloud backend / payment User (interface)
The EVerest project speeds up the emerging change to e-mobility by utilizing all the open source advantages for the EV charging world. It will enable new features for local energy management, PV integration, grid friendliness, and many more. By leveraging EVerest, you free up developers to focus on adding higher value to your product.
