Abstract
A vehicle includes a traction battery and a controller. The controller is programmed to detect a voltage measurement error associated with a battery cell. The controller is also programmed to, in response to detecting a voltage measurement error for a battery cell, initialize a state of charge of the battery cell according to an average change in stored capacity between power cycles.
