A controller, during DC fast charge of a traction battery, commands a DC charge current to have a magnitude less than a predefined value and responsive to magnitudes of resulting voltage drop data for a fast charge contactor connected between a charge port and main contactor being less than a first threshold value, commands the DC charge current to have a magnitude at a target high value.
