Sensors Solutions for Electric Vehicles

Honeywell’s Sensors for electric vehicles offer the best combination of performance and reliability

This new suite of sensor offerings enables improved electric vehicle performance and safety. They can also be used in battery energy storage systems.

Honeywell’s current sensors provide high-accuracy readings with low-temperature drift in several electric vehicle applications including Battery Management Systems (BMS), Power Distribution System (PDU), Battery Disconnect Unit (BDU) .

Honeywell’s battery safety sensors integrated into EV battery packs enable electric vehicle manufacturers comply with the battery fire safety requirements in international standards UN GTR No. 20 Electric Vehicle Safety, and the associated Federal Motor Vehicle Safety Standards. The battery safety sensors enable the early detection of thermal runaway to mitigate the loss of life and property. The battery safety sensors have programmable warning thresholds to fit specific battery configuration.
