  • Publication number: 20140361743
    Abstract: A vehicle having a battery pack with cells arranged in at least groups of two cells in series is disclosed. A controller balances the cells based on a change in voltage across the cells being different than an expected change in voltage. The expected value is based on a current and a time associated with charging or discharging the cells. A controller is disclosed that commands charging and discharging of the battery cells based on a difference between a voltage across the group and the expected value for the group. A method for charging and discharging a battery pack is disclosed. The voltage across a group of cells is measured and compared to an expected value. An imbalance in a cell attribute is estimated according to a difference between the measured voltage and the expected voltage. The voltage across each battery cell is not required.

  • Publication number: 20140277866
    Abstract: A vehicle having a battery pack with cells grouped into subsets and at least one controller programmed to charge and discharge the battery pack is disclosed. A control output is generated based on a pack state of charge derived from each cell's initial state of charge at vehicle activation and an electric charge accumulated or spent by less than all of the cells of each of the subsets since vehicle activation. A method of estimating battery pack state of charge is disclosed in which a pack state of charge is calculated by identifying subsets of cells having similar properties and calculating an electric charge accumulated or spent for fewer than all of the cells of each subset. A cell state of charge is calculated for all cells based on an average electric charge accumulated or spent. The pack state of charge is based on all the cell states of charge.
