Honeywell: Focused on Enabling Safety for Electrification

EV, Battery Storage, Battery Sensing, and Battery Safety

A suite of sensor offerings for enhanced safety in EV batteries and energy storage systems bring the best combination of performance and reliability. Honeywell’s current sensors provide high-accuracy readings with low-temperature drift to the Battery Management System for electrical management protection and state of charge monitoring. Honeywell’s battery safety sensors integrated into EV battery packs enable EV 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 detect early thermal runaway events and communicates to the vehicle system using CAN communication. The battery safety sensors have programmable warning thresholds to fit specific battery configuration.
