Abstract

A system configured to power a vehicle or vessel. The system may include an enhanced power control system. The enhanced power control system having a distributed architecture such that power conversion and/or management is provided for individual energy supplies and/or system loads. The distributed architecture of the power control system may enhance the power efficiency of the vehicle or vessel. The distributed architecture of the power control system may enable a plurality of different energy supplies and/or system loads to be incorporated into the power system in a selectable, configurable manner. This may facilitate the addition and/or subtraction of energy supplies and/or system loads from the system to customize the vehicle or vessel for a specific use and/or mission without having to reconfigure the power control system as a whole.

Claims

1. A system configured to manage power within an unmanned underwater vessel, the system comprising:

a power bus through which power is distributed to a plurality of system loads, the system loads comprising one or more of a sensor for detecting an environment parameter, a communications device, or a propulsion mechanism;

a plurality of load management modules configured to control the system loads, the plurality of load management modules comprising a first load management module coupled to a first system load and a second load management module coupled to a second system load, wherein each of the first load management module and the second load management module is separately coupled to the power bus, and wherein each of the first load management module and the second load management module comprises;

a power stage configured to condition the power received by the load management module from the power bus so that the received power can be used to power the corresponding system load;

a power controller configured to control the power stage as power received by the power stage is conditioned for use by the corresponding system load, wherein the control of the power stage by the power controller includes feedback control based on operating parameters of the power stage; and

a load controller configured to control the corresponding system load;

a system management processor in operative communication with the load management modules, the system management processor being configured to generate commands to the load controllers of the load management modules for controlling the system loads, the commands being determined based at least in part on mission parameters and one or more parameters of one or more energy supplies providing power to the system loads via the power bus.

2. The system of claim 1, wherein the one or more energy supplies providing power to the system loads comprises one or more of a fuel cell, an energy storage unit, a kinetic energy generator, a waste heat harvester, or a solar generator.

3. The system of claim 1, further comprising:

a plurality of supply management modules configured to control a plurality of energy supplies, the plurality of supply management modules comprising a first supply management module coupled to a first energy supply and a second supply management module coupled to a second energy supply, wherein each of the first supply management module and the second supply management module is separately coupled to the power bus, and wherein each of the first supply management module and the second supply management module comprises;

a power stage configured to condition the power provided by the corresponding energy supply to the power bus so that the supplied power maintains one or more predetermined parameters;

a power controller configured to control the power stage as power provided by the corresponding energy supply is conditioned by the power stage, wherein the control of the power stage by the power controller includes feedback control based on operating parameters of the power stage;

a supply controller configured to control the corresponding energy supply; and

wherein the system management processor is in operative communication with the supply management modules, the system management processor being further configured to generate commands to the supply controllers of the supply management modules for controlling the energy supplies to cooperate to maintain the potential of the power bus at a predetermined level, the commands being determined based at least in part on one or more parameters of the energy supplies providing power to the power bus.

4. The system of claim 3, wherein the one or more energy supplies providing power to the system loads comprises one or more of a fuel cell, an energy storage unit, a kinetic energy generator, a waste heat harvester, or a solar generator.

5. The system of claim 1, further comprising a user interface configured to receive mission parameters from a user, the user interface being operatively linked with the system management processor such that the received mission parameters are communicated from the user thereto.
