1. A method for estimating a vehicle battery parameter, comprising the steps of:

  • (a) determining an initial value for the vehicle battery parameter being estimated, the initial value is based on data gathered at a first sampling rate;

    (b) determining an adjustment factor for the vehicle battery parameter being estimated, the adjustment factor is based on data gathered at a second sampling rate that is faster than the first sampling rate; and

    (c) modifying the initial value with the adjustment factor to determine an overall value for the vehicle battery parameter being estimated, wherein the overall value takes into account changes to the vehicle battery parameter that are represented in the data gathered at the second sampling rate but are not represented in the data gathered at the first sampling rate.
