Yardney Technical Products in conjunction with Johns Hopkins University Applied Physics Laboratory is proposing to progress development of an advanced monitoring system for batteries, provide a modular battery unit, and develop a system approach to monitor and control multiple power sources and loads. Battery monitoring will be advanced via a technique to determine the internal temperature of each cell in a battery, thereby providing an opportunity to detect if a cell is approaching initiation of thermal runaway. The system will balance various parallel power sources to maintain thermal control of each by providing an opportunity to take one that is detected to be in jeopardy offline. The modular battery design will provide a unit consisting of cells and a battery management system, having advanced monitoring and control capabilities, as a standalone unit, or readily capable of arranging in a parallel and/or series configuration to meet requirements. This proposal addresses an advanced system monitoring and control approach, and a battery whose benefit is not to address how to fail safely, but rather how to prevent failure by detecting the anomalous behavior of a cell well before it fails.
