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.
