Orion 02 BMS — Standard (up to 180S)

The most widely adopted digital battery management system for lithium-ion packs. Versatile, robust, Made in the USA. Trusted by OEMs, FSAE teams, and integrators for over a decade.

Up to 180 cells in series
EMI-resilient centralized design
Dual CAN 2.0B
OBD-II support

Proven protection, precise control

The Orion 02 BMS monitors every cell for voltage and temperature, computes SOC/SOH, enforces charge/discharge limits (CCL/DCL), and drives contactors for safe, efficient operation. Centralized architecture delivers high EMI/noise immunity while maintaining automotive-grade reliability.

Key features

Measures up to 180 cells in series (configured in 12-cell increments).
Centralized design with excellent EMI immunity.
Intelligent passive balancing for pack health and longevity.
Accurate State of Charge (SOC) and limits (CCL/DCL).
Cell voltage range: 0.5–5.0 V.

Dual CAN 2.0B interfaces (fully programmable) + OBD-II support.
Automotive-grade locking connectors.
Rich diagnostics, fault logging, and thermal monitoring.
Integrates with chargers, VCUs, and displays via CAN.
Backed by extensive documentation and tools.

CAN termination note: Controller sizes 84–144 ship with both CAN1 & CAN2 internally terminated. All other sizes have CAN1 internally terminated (CAN2 is unterminated).

Configurations & chassis guidance

Choose a controller in series counts that match your pack (available in 12-cell increments). Typical chassis families:

24–72S

Compact chassis for small to mid packs, student EVs and prototyping.

84–108S

Mid chassis for commercial EVs, ESS cabinets, and robotics.

120–180S

Large chassis for high-voltage traction and utility-scale ESS.

FAQs

How many cells can the standard Orion 02 manage?

Up to 180 series cells, configured in 12-cell increments to match your pack.

What’s the difference between Standard and Split?

Standard is a single, centralized controller; Split supervises multiple physically separated segments as one system.

Is CAN termination built-in?

Yes. Sizes 84–144: both CAN1 & CAN2 are internally terminated. All other sizes: CAN1 terminated.

Can I integrate with a charger and VCU?

Yes. Dual CAN 2.0B with configurable messaging; OBD-II support is available for diagnostics and service tools.
