ABSTRACT:
A control circuit employed within an automotive electrical system for controlling the voltage transition rate between battery float and discharge levels in the presence of a switchable coupling between the battery and standard alternator. The control circuit includes means for regulating the alternator output voltage to said battery float level when the battery is coupled to receive charge current from said alternator, and for transforming said alternator output voltage to said discharge level at a predetermined rate prior to the battery coupling being switched to supply current to the load circuit, and further means for transforming said alternator output voltage to said float level at said predetermined rate after said battery coupling being switched to again receive charge current, whereby said predetermined rate provides a gradual change in the energization of said load circuit in the presence of the recited switchable coupling.
