A capacitive circuit with a supercapacitor is connected in series with a traction battery to provide a current sensor to produce a sensed signal that is linear across the operating range of the traction battery. The linear response of the capacitive circuit is an improvement over merely measuring the voltage across the battery, which is not linear over some ranges, e.g., 20% to 80% state of charge.
