Advanced Physical-Layer & Protocol Fault Injection

The SCS-100 features a deterministic, high-speed fault injection engine designed to evaluate the physical and digital safety limits of the Device Under Test (DUT) in real time. During active DC charging, the system can dynamically drift or spike the Control Pilot (CP) duty cycle beyond its mandatory 5% PWM threshold to evaluate protection reactions, and programmatically disconnect the CP or PP/CC lines at any stage to replicate cable malfunctions, pin degradation, or latch failures. Additionally, it allows engineers to inject out-of-boundary or attenuated HomePlug Green PHY PLC signals to validate the limits of high-level EVCC/SECC communication, while simultaneously generating corrupt CAN and LIN fault frames to ensure secondary vehicle networks execute safe-state transitions during digital interface failures.

SCS-100 Use case scenarios:

1. Signal Level protocol conformance testing

The SCS-100 connects directly to an EVCC or SECC ECU to validate software and logic conformance with global standards like ISO 15118, DIN 70121, and IEC 61851. By interfacing with the Control Pilot and Proximity Pilot lines, it simulates and measures ±12V PWM duty cycles, verifies PP resistance, and tests standard charging state transitions (States A to E) without requiring high-voltage hardware.

2. EVSE Simulator HIL

Simulating a real charger, the SCS-100 integrated with the ATE HIL system plugs into an EV to simulate charging protocol and deliver dynamic AC/DC power with sources. This validates the entire vehicle-side ecosystem—including the EVCC, BMS, OBC, and safety interlocks—simultaneously under real power conditions, grid constraints, and emergency shutdowns.

3. EV Simulator HIL

Simulating a real EV, the SCS-100 integrated with the ATE HIL cabinet plugs into a charger (EVSE) to simulate the EV charging protocol behaviors and sink dynamic AC/DC power using internal regenerative loads. This validates the charger's power electronics, safety systems, and control loops across diverse vehicle profiles (like 400V to 800V) while enabling the emulation of critical faults.

4. Man in the Middle

A non-intrusive Passive Man-in-the-Middle (MitM) Monitoring mode designed for real-time traffic analysis and physical-layer auditing between an active EV and EVSE link. Operating inline without disturbing standard handshake timings or line impedances, this feature captures, decodes, and logs all unencrypted high-level communication (such as HomePlug Green PHY EXI/XML messages across DIN SPEC 70121 or ISO 15118 without TLS) alongside CP PWM, PP analog states and power level parameters.
