| 20110130986 | System and Method For Maximizing a Battery Pack Total Energy Metric - A system and method for maximizing a battery pack total energy metric indicative of a total energy of a battery pack is provided. The method includes receiving battery cell charge capacity estimates for all cells in the battery pack, composing battery pack configurations comprising subsets of the totality of battery cells, evaluating a battery pack energy metric for every battery pack configuration that is composed, selecting the battery pack configuration that has the maximum battery pack energy metric, and storing values indicative of the selected battery pack configuration in a memory. | 06-02-2011 |
| 20110130985 | System and Method for Recursively Estimating Battery Cell Total Capacity - A system and method for determining an estimated battery cell total capacity indicative of a total capacity of a battery cell is provided. The method includes receiving a first battery cell state-of-charge estimate at a first time and receiving a second battery cell state-of-charge estimate at a second time subsequent to the first time, measuring an integrated battery cell current value indicative of the integrated battery cell current between the first time and the second time, updating at least one recursive parameter based on the first battery cell state-of-charge estimate, the second battery cell state-of-charge estimate, and the integrated battery cell current value, determining the estimated battery cell total capacity based on at least one recursive parameter, and storing a value corresponding to the estimated battery cell total capacity in a memory. | 06-02-2011 |
| 20110127960 | System and Method For Equalizing a Battery Pack During a Battery Pack Charging Process - A system and method for equalizing a battery pack during a battery pack charging process in accordance with an exemplary embodiment is provided. The method includes receiving total capacity estimates for all battery cells in the battery pack, and receiving state-of-charge estimates for all battery cells in the battery pack. The method further includes computing an equalization metric for all battery cells in the battery pack. The method further includes determining an equalization action for all battery cells in the battery pack, and initiating that equalization action. The method further includes executing a battery pack charging step. | 06-02-2011 |
