The article discusses the development of an Electric Vehicle Simulator (EV Simulator) to research and reverse-engineer Level 2 Electric Vehicle Supply Equipment (EVSE). The simulator is designed to mimic the behavior of an electric vehicle, allowing researchers to test the EVSE in different states, such as charging and idle. The EV Simulator is based on the SAE J1772 standard, which defines the communication protocol between the EVSE and the electric vehicle. The simulator uses a rotary switch to simulate different resistance values, which are used to communicate with the EVSE. The device also includes a diode and a low-cost oscilloscope to monitor the PWM signal sent by the EVSE. The authors emphasize the importance of safety when working with high-voltage equipment and provide a list of components used to build the simulator. The device was tested on several Level 2 chargers from different manufacturers and successfully placed them into the charging state. The authors also mention pre-built alternatives that can be used for research, but note that they may not provide the same level of control and measurement as the custom-built simulator. The article concludes by highlighting the importance of continued research into EVSE security and the potential for future contests and events focused on this topic.
