Abstract
An integrated circuit device includes a controller, an optional current source coupled to the controller, a voltage sampler coupled to the controller, a current detector coupled to the controller, and memory coupled to the controller, where memory includes code segments executable by the controller to: (a) apply a current pulse to a cell; (b) measure a voltage of the cell during the current pulse; (c) calculate an impedance of the cell from the measured voltage; and (d) determine an operational state of the cell from the impedance.
