The Orion BMS 2 can protect anywhere from 24 to 180 cells, for 1-16 cells, see the Orion Jr BMS. The Orion implements an extensive list of features designed to protect the battery pack. These features include:

  • State of charge calculations
  • Cell over-voltage and under-voltage protection
  • Intelligent battery balancing (passive)
  • Battery charger control
  • Pack temperature monitoring
  • Monitors health of battery pack

Cells are protected from over-voltage, under-voltage, over-current, over-temperature, and under-temperature based on the programmed minimum and maximum values in the battery profile.

Intelligent, efficient cell-by-cell balancing is provided to maximize the usable range of the battery. The BMS also monitors the health of both individual cells and the total pack and will trigger error trouble codes if either the pack or individual cells are in poor health.

The Orion BMS 2 is the second generation of an already popular and successful product, and boasts quite a few significant improvements, including a much lighter, smaller design, improved accuracy, additional inputs and hardware support for SAE J1772 charging protocol.
