A vehicle includes a traction battery and a controller programmed to, in response to a duration of current flow through the traction battery exceeding a predetermined duration, output a state of charge based on a first resistance value that is greater than a second resistance value used when the duration is less than the predetermined duration to compensate for a change in voltage drop caused by diffusion processes within the traction battery.
