Official abstract text for this publication.
Methods and systems for adjusting the voltage limits of a battery. In some implementations, voltage data may be received from each of a plurality of battery sections of a vehicle battery. A voltage offset for the vehicle battery may be calculated using the voltage data. The voltage offset may be calculated by determining a difference between an average voltage taken from each of the plurality of battery sections and at least one of a minimum voltage of all of the battery cells and an average cell voltage from a battery section having the lowest average cell voltage. The voltage offset may be applied to dynamically adjust a voltage limit associated with the vehicle battery so as to prevent any of the battery cells in the vehicle battery from exceeding the voltage limit.
Opening claim text (preview).
The invention claimed is: 1. A method for dynamically adjusting voltage limits of a battery, the method comprising the steps of: receiving voltage data from at least a plurality of battery cells of a battery; calculating a voltage offset for the battery using the voltage data; applying the voltage offset to adjust a voltage limit associated with the battery to prevent any of the battery cells in the at least a plurality of battery cells from exceeding the voltage limit; rece…
