Implementation of Multifaceted Safety Indicators-Based Battery Protection System for Battery Faults and Failures

In the realm of energy storage systems (ESS), the widespread use of lithium-ion batteries introduces significant safety challenges. In this paper, we propose a battery protection system (BPS) based on multifaceted safety indicators (MSI) to address these safety challenges. The MSI-based BPS enhances stable ESS operations by harnessing fundamental, domain-specific, and AI-based MSI modules for lithium-ion battery safety. The MSI-based BPS enables real-time monitoring and tracking on the edge cloud infrastructure without modification of functionalities in existing battery management systems (BMS). As a result of the demonstration conducted on the ESS testbed, we have validated the MSI-based BPS's effectiveness in preemptively identifying and mitigating potential battery faults and failures.
