Battery Thermal Runaway (TR) Sensor
High-Accuracy Battery TR Sensor by DEP
DEP offers a highly responsive Battery Thermal Runaway (TR) Sensor designed to provide early, reliable detection of internal instability within lithium-ion battery systems. Engineered for electric mobility applications, this sensor identifies ionized vent gases at the earliest stages of thermal runaway—far before traditional temperature, pressure, or voltage-based methods can react. With customizable sensor geometries, flexible mounting options, and seamless integration through a dedicated conditioning and amplification unit that supports multiple sensor connections, DEP’s TR Sensor delivers superior accuracy, rapid response, and reduced false alarms. This ensures enhanced battery safety, minimized operational risks, and consistent compliance with evolving global EV safety standards.

Key Distinguishers
Unique Performance of Our Thermal Runaway Sensor
DEP’s network of sensors stands out for its exceptional performance, ensuring rapid response and high reliability in detecting gas venting during thermal runaway events. By mitigating the drawbacks associated with other sensing technologies, this sensor provides a robust and accurate solution for early identification and prevention of thermal runaway incidents.
Early-Intervention Battery Safety Solution
Early-intervention battery safety is achieved by continuously identifying early signs of internal instability before they escalate into critical failures. Proactive, real-time risk assessment enables timely corrective actions, reducing the likelihood of battery pack damage and unplanned downtime. This approach also supports compliance with evolving global safety and certification requirements while lowering costs associated with failures, recalls, and warranty claims.
Critical Functions of TR Sensing Technology
Thermal runaway sensing technology provides real-time visibility into early-stage electrochemical disturbances within lithium-ion cells. It delivers:
Early-warning insights before temperature rise or voltage drop is detectable
Continuous monitoring to identify abnormal behavior with high accuracy
Rapid response, enabling preventive or mitigation actions
Regulatory alignment, supporting mandatory safety requirements for EV battery systems
