A collection of my EVBox research, documentation, software, downloads, and related projects. Most of this material concerns EVBox G2 and G3 HomeLine and BusinessLine chargers.

Autostart module

What is the autostart module?

A small replacement for the original EVBox modem that makes G2 and G3 chargers operate completely stand-alone. No backend, cellular connection or subscription is required. The module provides automatic charging when a vehicle is connected.

Autostart module installation manual

Step-by-step installation instructions for replacing the original EVBox modem with the autostart module.

Designing the autostart module

The story behind designing and building the autostart module, including the hardware, firmware, testing and the decisions that went into making it a simple drop-in replacement. It includes hardware designs, firmware, production files and other resources for building your own module.

Reversing the EVBox ChargeStation Tool

An exploration of the proprietary EVBox ChargeStation Tool used to configure EVBox chargers. This project reverse-engineers the software and its USB interface, and documents how to use open hardware instead of the original EVBox adapter.

ChargeStation Tool downloads

Copies of the EVBox software and the open-source physical and virtual adapter projects developed during the reverse-engineering work.

Turning a managed EV charger into stand-alone

The original reverse-engineering project. It documents how an EVBox charger communicates internally and how the original management functionality was replaced with software running on a Raspberry Pi. This project sparked all the others.

EVBox protocol "Max" documentation

Detailed documentation of the EVBox Max protocol used for communication between modules in G2 and G3 HomeLine, BusinessLine, and PublicLine chargers. Covers all network layers, as well as packet and frame formats and captures.

EVBox hardware documentation

A reference to the EVBox hardware documented during the reverse-engineering work, including charger boards, communication modules, and information on decoding serial and model numbers.

EVBox documentation archive

A collection of original EVBox documentation, including installation and commissioning manuals, local cluster documentation, pinouts, and the EVBox Max protocol specification.

Software implementation of charger and modem

Software developed during the project for simulating, communicating with, and controlling the EVBox charger.
