Summary of Major Improvements
  • Significantly smaller enclosure size for 24-72 cell configurations.
  • Roughly 40% lower weight on all models due to the new enclosure design and streamlined (removable) heatsink. Minimum heat dissipation requirements apply.
  • Considerable boosts in measurement accuracy and processor speed allow for more advanced calculations and logic.
  • Direct hardware support for several popular charging protocols including hardware support for SAE J1772 (directly interfacing with the pilot / proximity lines) and CHAdeMO for DC fast charging.
  • Wider input power voltage range (now 12v-24vDC compatible) for better support on heavy vehicles and equipment. The Orion 2 BMS remains fully compatible with 12v applications.
  • Ability to directly drive certain contactors on select inputs (bypassing the need for intermediate signal relays in some situations)–see supporting documentation for details.
  • Completely redesigned multi-unit series configuration (now using Remote Cell Tap Expansion Modules). This greatly simplifies connecting multiple units together in series and improves the overall reliability.
  • New Status LED on the unit to indicate power status and the presence of faults.
  • Addition of 2x new Multi-Purpose Output pins with programmable functions.
  • Significant algorithm and software enhancements to improve overall system accuracy for parameters such as State of Charge and pack health.

  • Configurations available in increments of 12 cells in series.
  • Centralized design provides high EMI and noise immunity.
  • Performs intelligent cell balancing (passive).
  • Calculates state of charge (SOC).
  • Uses professional automotive-grade locking connectors.
  • Calculates discharge current limit (DCL) and charge current limit (CCL).
  • Can measure cell voltages between 0.5v and 5.0v.
  • Dual (x2) CANBUS 2.0B interfaces which (fully programmable).
  • OBD2 diagnostic protocol support.
