Frequently Asked Questions About Electrification Sensors

Current sensors provide the near real-time data needed to optimize charging cycles, predict maintenance needs and extend battery life. Honeywell delivers high-accuracy measurements that enable battery management systems to make informed decisions about charge/discharge rates and cell balancing. Safety sensors detect thermal events before they impact performance, enabling preventive action. Combined performance and safety monitoring helps support efficient battery operation while reducing the risk of unexpected failures.

Yes. Our sensors use CAN 2.0B communication, the standard protocol in automotive and industrial battery systems. They feature configurable wake-up and request inputs for simple integration with existing power management schemes. Programmable warning thresholds allow customization to specific battery chemistry and pack design without BMS software changes. The sensors work with all common lithium-ion chemistries and support both new installations and retrofit applications.

Our sensors integrate with IoT platforms through CAN 2.0B interfaces for near real-time data streaming to cloud analytics. The sensors continuously monitor current, voltage, pressure, temperature and gas concentrations that feed predictive maintenance algorithms. This approach enables early identification of degradation patterns and potential failure modes before they impact performance. The architecture supports both edge processing for local decisions and centralized analytics for fleet-wide electrification management.
