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.

Question & Answer:
Q :
What exactly is the difference between the standard and this split configuration of the BMS? I am building a 94-cell EV battery pack with a mid-pack battery-disconnect with integrated HV fuse. Is the wiring harness just different so that voltages of both sub-strings can still be measured when the battery disconnect is unplugged or the fuse is blown? Is the split variant the right product choice for me then?
A: Hello, the special split Orion 2 BMS is designed for battery packs that are physically divided into separate sections, let's say you have 48 cells in front and 48 cells in the back. Apart from Standard version, cable wire harness is made with 4x 24 cells, while on standard version the cable wire harness is made from 1x 24 cells and 2x 36 cells.
