Systems and methods for measuring voltage of a battery pack for an electrified vehicle, such as an electric or hybrid vehicle, include a battery having internal circuits that measure pack voltage and individual cell voltages, an electric machine powered by the battery to propel the vehicle via an external circuit that measures the pack voltage, and a processor programmed to publish the pack voltage to a vehicle network based on a first internal circuit voltage in response to a voltage differential among the internal circuits being less than a threshold and based on the individual cell voltages otherwise. The published pack voltage may be used by one or more battery or vehicle controllers to control various battery and vehicle functions including engine starting in a hybrid vehicle and battery charging and discharging, for example.
