Whats New

  • 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.
