An Advanced Undersea Lithium Ion Management System (U-LIMS)

Impact Technologies, in collaboration with Penn State Applied Research Laboratory, proposes to develop an advanced Battery Monitoring and Management System (BMMS) for lithium-ion battery packs that ensures adequate, safe, and reliable operation. This system will focus on real time diagnostics, prediction of catastrophic failure, and risk assessment for individual cells in high power applications. Intelligent cell monitoring will be developed to automate the cell interrogation based on risk and time to failure estimates. Phase I will strive to demonstrate the ability to detect failure modes, predict when they will reach condemning limits at the cell/module level in real time, and respond to such conditions by taking the appropriate module offline to prevent damage. The architecture for intelligent cell monitoring will also be designed based on the host platform and target battery. Phase II will then extend these developments for full size cells and multi-cell modules and develop a prototype system to regulate cells during charge and discharge cycles. In Phase III, we will conduct shipboard testing and suitability analysis of the modeled system. Commercialization and transition plans will be developed for full scale implementation along with user manuals, training guides, and support plans.
