Critical sensing for cleaner energy solutions

Thermal runaway detection uses multiple sensing modalities working together.

• Battery pressure sensors measure absolute pressure (50-300 kPa) and rate of pressure change using MEMS-ASIC technology

• Battery aerosol sensors employ light scattering to detect smoke, liquid and debris particles released during thermal events

• Battery electrolyte detectors use proprietary gas sensing technology to identify electrolyte vapor, hydrogen and carbon monoxide gases

These sensors provide near real-time alerts via CAN communication to battery management systems. 

Current sensors support critical battery management functions including state-of-charge monitoring, charging control and fault detection.

• Consider current measurement range requirements for your battery pack voltage and capacity

• Evaluate accuracy specifications needed for precise state-of-charge calculations

• Review response time characteristics for motor control and fast-charging applications

• Verify CAN communication compatibility with your battery management system architecture

• Consider operating temperature range requirements (-40°C to 125°C typical for automotive applications)

• Assess mechanical packaging constraints and mounting configurations

Multiple Honeywell current sensor series (CSNV500, CSHV, CSSV1500) are designed for electrified vehicle applications including EV, HEV, PHEV and BEV platforms. These sensors provide current leakage detection and fault isolation capabilities for battery charging systems and can help improve overall battery system performance.
