ABSTRACT:
A diagnostic device for monitoring charging and discharging currents of a storage battery employing a current sensing resistor (shunt) adapted to be connected in series with a battery, the voltage and its polarity across the resistor being proportional to charging and discharging current through the battery and the direction of its flow. Amplifiers are employed for selectively amplifying charging and discharging currents with voltage to frequency converters providing trains of pulses responsive thereto which are compared by a microprocessor with stored programs for interpretation.
