FAILURE SIMULATION UNIT (FSU)

Product catalog summary

Overview: The document describes the Failure Simulation Unit (FSU) used in conjunction with a Battery Cell Simulator (BCS) to simulate failures in battery management systems, specifically focusing on wiring failures.

Specifications:

Communication via CAN-Bus at 500 kBd or 1 MBd.
Operates under laboratory conditions.
Connectors support 115 V / 230 V.
Supports cascading of 12 emulated cells per stack, with up to 10 slaves per master connected via ethernet cable.

Procedures:

Simulates cable breaks in measurement lines due to mechanical stress.
Includes a ripple filter for voltage and sense lines.
Test cases involve setting cells to different modes (LOAD_ONLY, NORMAL) and opening/closing relays.

Components:

FSU master and slave units for controlling up to 120 cells.
Includes features like high precision battery cell emulation, shunt emulation, and insulation monitoring.
Safety mechanisms include emergency stop and insulation monitoring.

Recommendations:

Use the FSU for extended fault insertion in battery cell simulators.
Ensure compatibility with the Battery Management System (BMS) for effective testing.
