    Abstract: A system and method for use with a vehicle battery pack having a number of individual battery cells, such as a lithium-ion battery commonly used in hybrid electric vehicles. In one embodiment, the method evaluates individual battery cells within a vehicle battery pack in order to obtain accurate estimates regarding their average transient voltage effect, open circuit voltage (OCVCell) and/or state of charge (SOCCell) so that a cell balancing process can be performed. These cell evaluations may be performed fairly soon after the vehicle is turned off and in a manner that utilizes a minimal amount of in-vehicle resources.

    Abstract: An embodiment contemplates a method for estimating a capacity of a battery. A state of charge is determined at a first instant of time and at a second instant of time. A difference in the state of charge is determined between the first instant of time and the second instant of time. A net coulomb flow is calculated between the first instant of time and the second instant of time. The battery capacity is determined as a function of the change in the state of charge and the net coulomb flow.

    Abstract: A rough road detection system includes an engine speed module, a feature space module, a normalization module, and a rough road module. The engine speed module generates an engine speed signal based on a crank signal. The feature space module generates a feature space signal based on the engine speed signal. The normalization module generates a normalized signal. The normalized signal is based on the feature space signal and a normalization value that varies in accordance with the engine speed signal. The rough road module determines whether a rough road condition exists based on the normalized signal.
