Power management assembly
First Claim
1. A power management assembly comprising:
- a first power source for supplying power at a first voltage and a second power source for providing power at a second, higher voltage;
a junction box for distributing power to a first set of electrical components and a second set of electrical components;
a busboard for electrically connecting the junction box to the first power source for providing power at the first voltage to the first set of electrical components and electrically connecting the junction box to the second power source for providing power at the second voltage to the second set of electrical components, the busboard comprising a plurality of busbars mounted on a single plate, the busbars having terminals through which the first and second power sources and the junction box are directly, electrically connected to the busboard; and
means for supporting the first power source, second power source and junction box on the busboard to provide a compact assembly.

Abstract
A power management system comprises a busboard for selectively managing the power from a forty-two volt source and a fourteen volt source in a vehicle dual voltage electrical system. The busboard has a lower plate with recesses for receiving variously configured busbars. The busbars have upright terminals for electrical connection with the voltage sources. The power from the voltage sources is directed along the busbars to other terminals extending at assorted locations from the busboard. An upper cover fits over the lower plate and covers the recesses. The upper cover has an area accommodating the forty-two volt source and housings for partially enclosing the other terminals. One of the housings forms a forty-two volt jump start post. Another of the housings forms a fourteen volt jump start post. The terminal in the fourteen volt jump start post is connected through a DC/DC converter to the forty-two volt source so power from a vehicle having a fourteen volt electrical system can be converted to forty-two volts and used to charge the dual voltage system. A relay mounted on the busboard is actuated to provide power to a vehicle starter when the batteries are charged. An additional housing provides a connection port for electrically connecting the busboard to a vehicle alternator. Two further terminals on the busboard enable connection of forty-two volt power and fourteen volt power to a junction box requiring each of the separate voltages for serving different sets of electrical components.
