From the project

An open-source, EV-side charging simulator. It emulates an electric vehicle so you can test AC charging stations (EVSE) and CSMS backends on the bench, without a real car.

An open-source, EV-side charging simulator. It emulates an electric vehicle so you can test AC charging stations (EVSE) and CSMS backends on the bench, without a real car.

Built around a Seeed XIAO ESP32-S3 on a small carrier PCB, it drives the SAE J1772 / IEC 61851-1 Control Pilot line through states A, B, and C, reads the charger's offered current from the CP PWM, and reports proximity. A charger sees a full session lifecycle: vehicle detect, transaction start, Charging status, offered current, transaction stop.
