Patent number: 9465077Abstract: A method and system for monitoring the health of a battery is provided. A precision frequency can be determined for the battery by applying one of an AC current or voltage perturbation across a frequency sweep with impedance spectroscopy equipment to obtain an impedance response; collecting data related to the impedance response at a plurality of various states of charge within a recommended voltage window of the battery; plotting the collected data on one or more impedance curves; and analyzing the one or more impedance curves at the various states of charge to determine the precision frequency.
