Abstract: examples provide a method that includes providing electric power at a first voltage level for a first auxiliary low voltage bus. the method further includes providing electric power at a second voltage level for a second auxiliary low voltage bus, the first voltage level differing from the second voltage level. the method further includes sensing, by a controller, a first power consumption at the first auxiliary low voltage bus. the method further includes sensing, by the controller, a second power consumption at the second auxiliary low voltage bus. the method further includes calculating, by the controller, a difference between the first power consumption and the second power consumption. the method further includes managing a load in one of the first auxiliary low voltage bus or the second auxiliary low voltage bus based at least in part on the difference between the first power consumption and the second power consumption.

CPC Code(s): H02J3/14
Abstract: examples described herein provide a method that includes providing a first electric power pathway from a battery to a first auxiliary low voltage bus via a direct-current (dc)/dc converter and a first switch. the method further includes providing a second electric power pathway from the battery to a second auxiliary low voltage bus via the dc/dc converter and a second switch. the method further includes selectively controlling at least one of the first switch or the second switch to manage a load in one of the first auxiliary low voltage bus or the second auxiliary low voltage bus based at least in part on the battery or the load.

CPC Code(s): H02J3/322
Abstract: examples described herein provide a method that includes providing electric power at a first voltage level for a first auxiliary low voltage bus. the method further includes providing electric power at a second voltage level for a second auxiliary low voltage bus, the first voltage level differing from the second voltage level. the method further includes adjusting the second voltage level using a direct current (dc)/dc bypass converter. the dc/dc bypass converter converts electric power from the first auxiliary low voltage bus and delivers an adjusted electric power to the second auxiliary low voltage bus to regulate power drawn in the first auxiliary low voltage bus and the second auxiliary low voltage bus.
