BeagleBone V2H Charger

Bidirectional CHAdeMO · Reverse engineered

4

Bidirectional Vehicle-to-Home CHAdeMO charging system running on BeagleBone Green. Reverse-engineered from an Indra commercial V2H unit. Implements the full CHAdeMO handshake over dual CAN channels — one for EV control, one for inverter coordination. Written in async Rust with real-time control loops.

Toucan CAN Protocol Converter

STM32F407 · EV battery → ESS inverter

STM32F407-based firmware that translates EV battery CAN protocols into the formats expected by stationary energy storage inverters. Enables repurposing of EV battery packs — such as those from the Nissan LEAF — into domestic energy storage. Built with Embassy-rs async runtime and RTIC concurrency framework.
