Abstract
A control system for a vehicle includes a controller. The controller is configured to open traction battery contactors based on a potential between high-voltage cables and a chassis continuously exceeding an amplitude threshold for at least a predefined duration of time. The controller is further configured to selectively open the contactors based on data derived from the potential for periods that are each defined by the potential exceeding and then falling below the amplitude threshold without exceeding the predefined duration of time.
