The BPS Series are automotive-grade pressure sensors designed to detect and report thermal runaway events in lithium-ion battery packs. They use a combination of MEMS (Micro- Electromechanical System) and ASIC (Application-Specific Integrated Circuit) technologies to detect pressure changes in the battery packs of electric vehicles and energy storage systems (ESS). The detected value is transmitted to the battery management system (BMS) using CAN (Controller Area Network) communication. The BPS Series measures from 50 kPa to 300 kPa absolute pressure. It has settable warning thresholds for both absolute pressure and rate of change of pressure.
