Abstract
A vehicle battery system includes a traction battery having positive and negative terminals, and resistive circuitry including a first resistor electrically connected between one of the terminals and a common ground, a switch, and a second resistor that can be selectively electrically connected between the one of the terminals and the first resistor via the switch. The vehicle battery system also includes a controller that opens and closes the switch, and inhibits charge of the traction battery according to changes in voltage across the second resistor due to opening and closing of the switch.
