    Abstract: Methods and systems are provided that determine a voltage of a cell of a battery pack of a vehicle. A sensor is configured to measure a preliminary value of the voltage of the cell while the battery pack is being balanced. A processor is coupled to the sensor, and is configured to determine an offset from balancing of the battery pack, and calculate an adjusted value of the voltage of the cell using the preliminary value and the offset.

    Abstract: A system and method is provided for estimating the capacity of a battery element in a vehicle, such as a hybrid electric vehicle. In one embodiment, the method determines if one or more threshold conditions have been met (e.g., conditions pertaining to battery temperature or battery state-of-charge (SOC)) and calculates the internal resistance of the battery element. When the threshold conditions have been met, the method uses the calculated internal resistance to estimate the capacity of the battery element. A corresponding battery system is also provided that includes a battery element, one or more battery sensors, and a control module configured to perform the method described above.

    Abstract: System and methods for balancing a vehicle battery system are presented. In certain embodiments, a method for balancing a vehicle battery system including a plurality of sections may include calculating a plurality of quanta of energy required for each of the plurality of sections to reaching a balancing point. Based at least in part on the calculated plural of quanta of energy, it may be determined that the plurality of sections of the battery system are unbalanced. To balance the battery system, a balancing system may be selectively actuated to change the amounts of energy stored in one or more of the plurality of cells such that the plurality of quanta of energy are within a particular range.

    Abstract: A method for estimating the voltage of a battery element of a vehicle battery system is provided. The method comprises providing a balancing/sensing circuit having a series combination of a balancing switch and a balancing resistive element electrically connected in parallel with the battery element, and measuring the voltage across the combination of the balancing switch and balancing resistive element when the balancing switch is presumed to be in a “closed” state. The method further comprises deriving a compensated value for the measured voltage using empirically-derived data, wherein the compensated value compensates for a voltage drop occurring in the balancing/sensing circuit when the balancing switch is in the “closed” state and represents an estimate of the voltage of the battery element. A battery system is also provided that includes a battery element, a balancing/sensing circuit, a sensor, and a control module configured to perform the method described above.
