ABSTRACT:
A difference amplifier compares the sum of a signal corresponding to the voltage across the battery and a signal corresponding to the current through the battery to a reference signal. When the output of the difference amplifier indicates that the sum of the two signals is less than the reference signal, a limiter circuit responds to limit the current drawn from the battery by controlling a current regulator interconnected between the battery and its load. If desired, a temperature signal indicative of the battery of temperature can also be applied to the difference amplifier so that the point at which the regulation sets in varies as a function of temperature.
