Systems and methods for measuring voltage of a battery pack for an electrified vehicle, such as an electric or hybrid vehicle, include measuring individual cell voltages and using the individual measurements to periodically update an adjustment or offset applied to the battery pack measurement to improve accuracy of the battery pack measurement. Individual cell voltage measurements may be periodically sampled and combined with the result compared to the pack voltage under predetermined operating conditions, such as when voltage changes or variation are small. A sliding window of voltage differences that satisfy one or more specified conditions, such as being within a range of a previously determined value, may be used to generate the adjustment or offset.
