Building an electric vehicle simulator to research EVSEs

This blog describes building a safe, minimal EV simulator for Level 2 EVSE research using the SAE J1772 standard, enabling researchers to force chargers into disconnected, connected, and charging-request states to support testing (including Pwn2Own Automotive scenarios). It covers safety warnings, control pilot signaling and duty-cycle interpretation, the use of a rotary switch to set resistor states, onboard PWM monitoring, design considerations, and mentions limited pre-built alternatives.
