Introduction to EVerest Core

EVerest is a Linux Foundation Energy backed open-source modular framework for setting up a full stack environment for EV charging. The modular software architecture fosters customizability and lets you configure your dedicated charging station based on interchangeable modules.

​
What is EVerest Core?

EVerest Core is the open operating system for e-mobility charging stations. It provides a complete, production-ready software stack that enables manufacturers and developers to build advanced EV charging solutions without starting from scratch. All communication between modules is performed by the lightweight and flexible MQTT message queueing service. EVerest helps speed the adoption to e-mobility by utilizing all the open-source advantages for the EV charging world. It also enables new features for local energy management, PV-integration, and many more.

​
