Energy storage state of charge tracking in high frequency cycling application

Abstract

A power management system may include a power converter to provide output power to one or more loads from at least one of a primary power source or a backup power source, where the power converter is operable in at least a power smoothing mode, and where the power converter in the power smoothing mode shields the primary power source from periodic load swings by periodically charging and discharging the backup power source to compensate for the periodic load swings. The system may further include a controller including one or more processors configured to execute program instructions causing the one or more processors to generate state of charge measurements of the backup power source in the power smoothing mode based on a weighted combination of two or more state of charge measurement techniques.
