Abstract

A battery life monitoring approach for a power transformation powered system. “Signature profiling” and “power metering” may deal with statistically significant edge cases. Relative to product resources, a battery management module (BMM) may use software services from a “phantom module”, “power broker” and other low level board support package (BSP) software, such as A2D, time bases and memory R/W in order to execute routines needed for successful deployment of the product. The memory resources should be volatile and non-volatile memory resources to fulfill the needs of a fully functional power transformation BMM system.
