Abstract

There is disclosed an electrical system that converts a first DC voltage from an energy source, such as a battery, into a second lower DC voltage so that electrical components that cannot tolerate the first DC voltage can be powered from the lower voltage tapped from the energy source. The electrical system includes: a battery having a first voltage; a controller; a load; and an energy storage device. The battery has a plurality of battery portions, each of which has a voltage less than the first voltage. Each of the battery portions is electrically connected to the controller. The load and the energy storage device (preferably a capacitor) are electrically connected in parallel with the controller. The controller includes a logic circuit such that the controller operates to sequentially connect and disconnect each battery portion to the load and the energy storage device. In this arrangement, the lower voltages from each of the battery portions are applied to the load rather than the higher first voltage of the battery thatcould burn out the electrical components or components that comprise the load. In one version of the invention, the electrical system is incorporated into a vehicle electrical system so that vehicle electrical components that cannot tolerate higher voltages, such as 36 volts from a vehicle battery, can receive lower voltages, such as 12 volts, for operation.
