Abstract
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.
