Multiple voltages DC battery power supply system
First Claim
1. A multiple voltage battery power supply system for operating a plurality of vehicle electrical loads at selected voltage output levels, the system comprising:
- a first power block providing a first voltage output for operating vehicle electrical loads at a first voltage level;
a second power block connected in series with the first power block and substantially electrically similar to the first power block, the second power block providing a second voltage output independent from the first voltage output for operating vehicle electrical loads at a second voltage level;
wherein each power block independently maintains a substantially constant voltage at each corresponding voltage output and the series combination of each power block maintains a substantially constant third voltage output across both the first and second power blocks for operating vehicle loads at a third voltage level.

Abstract
A multiple voltage battery power supply system for operating a plurality of electrical vehicle loads at select voltage output levels is provided. The battery power supply system generally comprises at least two power blocks, each power block providing a voltage output for operating electrical vehicle loads. The at least two electrical power blocks are cascaded in series to provide a plurality of voltage output levels for powering vehicle loads at various rated voltages. Each power block independently maintains a substantially constant voltage, while the series combination of each power block also maintains a substantially constant voltage output across selected groups of blocks.
