Abstract

A system is provided that evaluates an energy state. The system comprises a sensor, bins, and a processor. The sensor is communicatively coupled to at least one cell that is powering an electric load. The sensor is operative to collect samples, each representing a measure of current discharged from the at least one cell during a discharge event. The bins are stored in a memory, and are accessible by the processor. The processor is programmed to sort the collected samples into bins based upon sample value. The processor is also programmed to create a use estimate based upon samples sorted into their corresponding bins. Yet further, the processor is programmed to determine a fractional depletion for each bin, each fractional depletion being a quotient that is computed by dividing an expected value for that bin by the use estimate for that bin.
