Munitions energy system
First Claim
1. A munitions energy system for providing electrical energy to a munition, the system comprising:
- an energy harvesting device, the energy harvesting device generating electrical energy based on an environmental condition of the munition, wherein the energy harvesting device includes;
a motion harvesting device which generates electrical energy based on a motion of the munition,a thermal harvesting device which generates electrical energy based on a thermal condition of the munition, andan electromagnetic harvesting device which generates electrical energy based on electromagnetic radiation received by the munition;
an energy storage device, the energy storage device storing electrical energy generated by the energy harvesting device; and
an energy management device, the energy management device managing the flow of energy among the energy harvesting device and a load, the energy harvesting device and the energy storage device, and the energy storage device and the load, wherein the energy management device manages the flow of energy in a maintenance mode and an operational mode of the munition.

Abstract
A munitions energy system combines various sources of energy generation with energy storage to provide power to a munition through various stages of the munition'"'"'s operation. The system uses energy harvesting technologies which convert energy captured from the environment of the munition to electrical power which can be used to meet the munition'"'"'s power needs. Energy can be harvested from the mechanical, thermal, and electromagnetic environment of the munition. The harvested energy can be stored by the system for later use. The system can also receive energy from conventional sources such as batteries and manage the energy from all sources to meet the power requirements of the munition.
