Abstract
An apparatus and method for providing supplementary power to an electrical system of a vehicle or other machinery is provided. The apparatus and methods specifically provide a rapid-delivery of high amounts of power. The significant power levels are sufficient, for example, to turn the starter of a heavy-duty commercial transport vehicle stranded by a disabled battery. The power is supplied by a power source having the combination of high-density capacitor and battery. The power delivery is controlled to avoid such standard problems as reverse or same polarity connections and overvoltage. Control is effected by a combination voltage sensing circuit and isolation circuit to prevent current between the power source and the electrical system unless prescribed conditions are satisfied. The energy level of the power source is sustained by the capacitor-battery combination along with the capabilities to receive return charging from the electrical system as well as from alternating current and direct current sources.
