Various aspects of invention provide portable power manager operating methods. One aspect of the invention provides a method for operating a power manager having a plurality of device ports for connecting with external power devices and a power bus for connecting with each device port. The method includes: disconnecting each device port from the power bus when no external power device is connected to the device port; accessing information from newly connected external power devices; determining if the newly connected external power devices can be connected to the power bus without power conversion; if not, determining if the newly connected external power devices can be connected to the power bus over an available power converter; and if so, configuring the available power converter for suitable power conversion.

Power managers and methods for operating power managers

An improved power manager includes a power bus () and multiple device ports (-), with at least one device port configured as a universal port (and) to be selectively connected to the power bus over an input power channel that includes an input power converter () or over a output or universal power channel () that includes an output power converter (). The universal power channel () allows the input port () to be selected as an output power channel instead of an input power channel (i.e. operated as a universal port) for outputting power to device port () over power converter (). The improved power manager () includes operating modes for altering an operating voltage of the power bus (), to minimize overall power conversion losses due to DC to DC power conversions used to connect non-bus voltage compatible power devices to the power bus.

Power manager

A power manager including a power bus operable at a DC bus voltage. A plurality of device ports operably connect to the power bus. A first data processing device and a first memory device are associated with the first data processing device. A data communication channel extends between the first data processing device and each of the plurality of device ports. An energy management schema operates on the first data processing device. For each of the plurality of device ports, the energy management schema establishes a communication link with an external power device connected to the device port over the data communication channel and determines if an external power device is connected to the device port and if so, determines an external power device type.

An electronics device carrier for porting a battery powered electronic device is formed by outer walls surrounding a hollow volume. The electronic device is held within the hollow volume and can be operated without removing the electronic device from the carrier. An input interface comprising interface elements external to the outer walls provides an element suitable for interfacing with external power devices such as a power source or another power load. A device interface includes interface elements at least partially disposed internal to the outer walls for interfacing with the electronic device battery. A charge controller is disposed between the input interface and the device interface and is operable to connect elements connected to the input interface to the device battery to either recharge the device battery or use the device battery as a power source.

Portable electronic device carrier with electronic interface for recharging device battery

A portable DC power manager () includes an internal power bus () and a plurality of device ports () for connecting with external power and energy sources, external power loads and other external power managers. Each device port is isolated for the internal power bus by controllable switches (A, B, C, D). Power converters () may be disposed between device ports and the internal power bus to convert voltages and attenuate current amplitude. Energy management schema operating on the power manager sums available power and allocates the available power to connected power loads according to power priority settings. A hot-change-over circuit () connects additional sources to the internal bus in response to a voltage drop on the internal power bus. A compact and lightweight package () enables a portability.
