FAILURE SIMULATION UNIT (FSU) FOR SIMULATION OF WIRING FAILURES. To complete the failure simulation of the Battery Cell Simulator, an additional FSU is used to simulate the breaking of measurement wires between BMS and the cells. FSU slave (Failure Simulation Unit slave) FSU slave (Failure Simulation Unit slave) (Battery Management System) FSU slave (Failure Simulation Unit slave) Technical data Communication: Temperature range: Connector: Cascading of 12 emulated cells to a stack (per slave) Up to 10 slaves per master (via ethernet cable) Cable break of measurement line Different settings for...
