Emulating Control Pilot Signal to Validate Electric Vehicle Charging Controller
Application Notes
This application note explains how programmable waveform generators can emulate IEC 61851 Control Pilot (CP) signals to validate electric vehicle charging controllers. It covers CP signal communication, charging states, PWM duty cycle, signal interruption, amplitude degradation, and composite charging scenarios. By replacing a physical EVSE with repeatable, programmable waveforms, engineers can accelerate firmware development, improve fault handling, and perform consistent design verification in a controlled laboratory environment.
