ADAPTIVE AVAILABLE POWER ESTIMATION FOR HIGH VOLTAGE LITHIUM ION BATTERY

摘要

The present invention provides for a method and computer program product for estimating battery available power from a battery system in relation to a cell voltage, comprising: determining the cell voltage, a power command of the battery system; and a cell voltage threshold. The processes used by the present invention, include a static and a dynamic portion in which cell voltages, cell voltage thresholds and power command are associated and processed using a feed forward estimator and a proportional-integral-derivation (PID) controller to determine the final power command estimation for the requisite battery system.
