Orion BMS Current Sensors (±200A · 500A · 750A · 1000A)

Dual-range Hall-effect sensors purpose-tuned for Orion BMS. Size for your peak current, keep accuracy at low current, and give the BMS the data it needs for safe, precise control.

  • Dual-range package
  • High accuracy at low current
  • Bidirectional (charge/discharge)
  • CAN-friendly telemetry via Orion

Why the current sensor matters

While technically optional, the current sensor unlocks most of Orion’s intelligence. Without it, Orion cannot compute SOC, SOH, internal resistance, CCL/DCL, or detect weak cells and over-current events. Accurate current data drives protection, range prediction, and charge control.

How to size the sensor

Pick the smallest sensor that safely covers peaks

  • Target: choose a rating above your highest expected transient, not just continuous.
  • Example: 275 A peak → pick 500 A (headroom for spikes).
  • Example: 190 A peak → pick 500 A (200 A is borderline for transients).

Smaller ranges improve low-current accuracy, but a little oversize is safer than clipping.

Dual-range = accuracy + redundancy

Each part includes two sensing ranges inside one package: a smaller internal range for finer low-current resolution and a larger range for peaks. Orion uses both to improve fidelity and robustness.

Available ranges

Nominal Range (bidirectional) Recommended Use Notes
±200 A Light EV, robotics, small ESS Best small-current resolution; ensure headroom for spikes.
±500 A General purpose traction / mid ESS Common choice when peaks sit 200–350 A.
±750 A High-demand traction / larger ESS For systems with frequent 400–600 A bursts.
±1000 A Heavy traction / industrial Use when peaks approach 800–900 A.

Wiring & installation notes

  • Orientation: follow the arrow/marking so positive current (discharge) matches Orion’s sign convention.
  • Conductor fit: route the main conductor centrally through the aperture; avoid edge contact.
  • EMI hygiene: keep HV busbars and high-dI/dt conductors away from sense leads; twist/route per Orion manual.
  • Thermal: sensor is non-contact; maintain clearance from hot components and provide strain relief for leads.

FAQs

What happens if I undersize the sensor?

Clipped peaks reduce accuracy and can compromise over-current protection and SOC/limit calculations. Always allow headroom.

Does Orion require a current sensor?

Orion can run without one, but most features (SOC, SOH, IR, CCL/DCL, weak-cell detection) depend on accurate current.

Are these sensors bidirectional?

Yes—specified ranges are ±, covering both charge and discharge current.
