Abstract

An apparatus for sensing current of a vehicle battery employs an extended counting analog-to-digital conversion process () to a chopped and amplified voltage appearing across a low ohmic shunt resistor () placed between the negative pole of the vehicle's battery and the chassis ground of the vehicle. Gain adjustment control of a programmable gain amplifier () by matching the gain to the dynamic range of the ADC () permits a high dynamic signal sensing.
