BPS series

To the inquiry list

Battery pressure sensors

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 to 300 kPa absolute pressure. It has settable warning thresholds for both absolute pressure and rate of change of pressure. The BPS Series allows early detection of a thermal runaway event in a lithium-ion battery pack. This product delivers on performance and reliability.

The BPS Series is automotive qualified and incorporates integrated circuits that are AEC-Q100 qualified to meet higher quality and reliability requirements. The BPS series is RoHS compliant.

Features:

• High accuracy and low temperature drift
• CAN communication protocol
• Wake-up output and request input for high reliability system integration
• Settable warning thresholds for absolute pressure and rate of change of pressure allow use with different equipment types
