Global ET Power Control Unit (SIMPCU) Module Graphic The SIM Power Control Unit (SIMPCU) is a solid-state smart switch that provides point-of-load and / or circuit level distributed monitoring, control, and protection of vehicle electrical loads. The SIMPCU is designed to support robust power management functions at the point-of-load.

The available features include power control (on, off, and Pulse Width Modulation (PWM)), local current & voltage fault detection, and operation with a system level Power Management Application (PMA). PWM operation is configurable to various levels and ramp-up slopes. The SIMPCU has built-in fault detection (thresholds and maturation timing are configurable). Extreme faults are handled locally at the SIMPCU. In an extreme fault, the SIMPCU will locally process and react to extreme and potentially damaging situations within milliseconds and the fault is immediately reported to the PMA. Subtle or matured faults are used to detect loads that are starting to exhibit operational degradation.  This diagnostic & prognostic information is processed to offer “condition based maintenance” - an optimized balance between unnecessary scheduled maintenance and maintenance due to failure.  The SIMPCU has built-in CAN communications, so it can be used within a managed and optimized power system.  If CAN communication is lost or damaged, the SIMPCU will revert to local, robust operation, which can be configured.  The SIMPCU consists of a Power Board capable controlling current in excess of 100 Amps and power in excess of 5 KW.

 

The PCU Enables System-Level:

  • Situational Awareness
  • Condition Based Maintenance
    • Diagnostics / Prognostics
    • Automated Maintenance Operations
    • Automated form 2404 Generation
  • Power Management
    • Mode-Based Load Control
    • Load Prioritization
    • Load Shedding
    • Load Reconstitution
    • Power Optimization
  • Power Integration
    • Controls Precise Power Contribution and Management from Power Generation and Energy Storage Devices
  • Subsystem Control
    • Such as Thermal Management Systems
  • Safety & Survivability
  • Configurability
  • Planning & Training
  • After Action Reporting

At the Point of Load, the PCU Provides:

  • Interconnectivity (CAN Communication)
  • Real-time Local Load Control
  • Load Protection
    • Locally validates extreme load conditions within milliseconds
    • Key settings are reconfigurable over CAN
    • Reverse Battery Protection
  • Elimination of In-rush Transients
    • with Soft Start and Soft Stop

The PCU is a control module that can be customized to work directly with energy storage and power generation devices.

The SIMPCU can be networked on the CAN bus to work in concert with many SIMRIOs and many other CAN devices to provide data collection and control for power management applications. The SIMPCU could relay data to a SIMPMC which in turn can translate to many other networks and protocols including wireless ethernet, USB, Zigbee, as well as industrial networks such as Modbus, LonWorks, BACnet, Ethernet/IP, Metasys, DH+, Profibus, ControlNet, SNMP, etc.
