Abstract
Methods and systems are provided that determine a voltage of a cell of a battery pack of a vehicle. A sensor is configured to measure a preliminary value of the voltage of the cell while the battery pack is being balanced. A processor is coupled to the sensor, and is configured to determine an offset from balancing of the battery pack, and calculate an adjusted value of the voltage of the cell using the preliminary value and the offset.
