Wearable power management system

摘要

The present disclosure sets forth a power management system including a plurality of power management devices configured to transfer power among a plurality of external devices. The power management system includes a first power management device and a second power management device. The first power management device includes a first, second and third communication ports along with first, second and third power ports. The second power management device includes fourth, fifth and sixth communications port along with fourth, fifth and sixth power ports. The first power port of the first power management device is coupled to the fourth power port of the second power management device such that first and second power and the first communications port of the first power management device is coupled to the fourth communications port of the second power management device.

主权项

1. A wearable power management apparatus comprising:
an elongated wearable portion comprising a generally flat flexible strap-shaped geometry configured to be worn by a human user, the elongated wearable portion including a mechanically flexible outer material; a first power and communications port disposed directly on the wearable portion at a first discrete location; a second power and communications port disposed directly on the wearable portion at a second discrete location, the second discrete location being spaced along the strap-shaped geometry of the elongated wearable portion apart from the first power and communications port by an intervening portion of the mechanically flexible outer material; a first electrical lead embedded in the wearable portion for routing electrical current at a first electrical lead electric potential level, to and from the first power port; a first electrical parameter sensor embedded in the wearable portion and configured to measure a first electrical lead electrical parameter to and from the first power port; a second electrical lead embedded in the wearable portion for routing electrical current at a second electrical lead electric potential level; a second electrical parameter sensor embedded in the wearable portion and configured to measure the second power electrical parameter; a buck boost converter electrically coupled to both the first electrical lead and the second electrical lead, the buck boost converter being configured to convert electrical current between the first electrical lead electric potential level and the second electrical lead electric potential level at a controlled potential conversion level; a controller being configured to receive operating current from either one of the first electrical lead and the second electrical lead, the controller configured to monitor the first electrical parameter sensor and the second electrical parameter sensor and being configured to output control signals to the buck boost converter, said control signals being determined based on the first electrical lead electrical parameter and the second electrical lead electrical parameter.
