Interface Simulation Logic
Simulation vs Energy Dissipation:
This system simulates EV side interface states, CP / PP behavior, and fault conditions for AC charger validation. It does not include built in power dissipation hardware. Real power aging tests or thermal endurance verification require an external AC load bank.
Pass Through Test Logic:
Introduction of external load equipment is supported for real current testing up to 21 kW class three phase environments, where the tester functions as a monitoring node within the charging path.
Vehicle State Emulation
Supports charger state machine validation through CP voltage levels and S2 switch behavior. Engineers can simulate charging ready (State C) and ventilation scenarios (State D) to verify relay response and connection transitions.
Duty Cycle & PWM Analysis
Measures and displays CP PWM duty cycle in real time. This allows verification of charger current advertisement logic, such as confirming 32A class signaling (53.3%) or 16A class signaling (26.6%) behavior.
Safety Logic & Fault Injection
Integrated fault simulation includes:
- Grounding loss and CP to ground fault scenarios
- CP open circuit and abnormal signal conditions
- Validation of EVSE safety shutdown and leakage protection response
- Fault response timing evaluation for R&D labs
Independent Logic Operation
System power architecture:
- Independent 12V control side power supply
- Continued diagnostic visibility during charger shutdown events
- Maintains signal monitoring independently of EVSE main power path
- Diagnostic data integrity preservation during fault events
