Sensata Releases OmniNode for High-Voltage Commercial EV Distribution
The integrated unit handles up to 1,000 V DC and 500 A continuous current without requiring active cooling.
Sensata Technologies has introduced the OmniNode, a patent-pending, off-the-shelf high-voltage power distribution unit designed for battery-electric commercial vehicles. The system consolidates DC charging, switching, circuit protection, sensing, diagnostics, and communications into a single integrated component.
What Happened
The OmniNode is built from Sensata’s own components, including contactors, fuses, and current sensors. According to the product specifications, the unit operates at voltages up to 1,000 V DC with a continuous current rating of 500 A. It features a boost rating allowing 700 A for 15 minutes at 60° C, though current derates at higher ambient temperatures. The company states the unit requires no active cooling, even in low-airflow environments, and operates within an ambient temperature range of −40° C to 85° C at altitudes up to 4,000 meters. Protection features include overcurrent coverage up to 1,250 A at 850 V and bidirectional short-circuit protection spanning 1.25 kA to 40 kA. The controller supports 12 V and 24 V nominal low-voltage systems, communicates via CAN 2.0B, J1939, and CAN FD, and includes standard AUTOSAR software.
Why It Matters
Sensata positions the OmniNode as a solution to reduce reliance on custom-engineered power distribution solutions for OEMs. By standardizing the unit, the company claims it cuts integration and validation work while simplifying sourcing. The design is intended for reuse across different vehicle programs and configurations, which could accelerate development timelines for Class 5 and above trucks and buses. Brian Wilkie, Sensata’s Executive Vice President and President of Aerospace, Defense and Commercial Equipment, stated the approach helps engineers simplify architecture and bring greater consistency to vehicle platform design.
The Bottom Line
Sensata’s OmniNode offers a consolidated, off-the-shelf alternative to custom high-voltage distribution units for commercial EVs, aiming to streamline OEM integration and validation processes for heavy-duty electric trucks and buses.
