A Concept of Minimizing an Electric Power Supply System for Portable Gear and Arms

Abstract

Currently a much higher number of portable devices with improved functionality supporting our job-related and social activities require higher and higher capacity and power offered by sources of power supply. Theoretical analysis of the possibility to achieve exploitation features of currently known portable sources of electric current has led the author to a conclusion that even the best solutions will not meet the desired mass and volume magnitudes in relation to the energy supplied. Therefore, if the sources of energy have reached the physically and economically justified capability limits and they are characterized by significantly varied exploitation properties, a solution combining the advantages of various sources of energy through energy management seems to be sensible. In this connection this article presents the idea of a system of energy control, which using available cells will allow for reducing the weight of power supply systems. The considerations are based on defense-related applications, this, however, does not exclude applications for civilian purposes.

Sizing and Control Algorithms of a Hybrid Energy Storage System Based on Fuel Cells

“…The energy profiles bring information about the current power demand and dynamics of the connected load. More specific information on how the energy profiles were created can be found in previous publications [40,41].…”

“…Using the energy profiles (Figure 1) generated according to the methodology described in [40,41], one can determine the electrical parameters (including mass) of the system that will be able to power the considered group of loads. Assuming that the random nature of the load is closest to the phenomena occurring in real situations, one should adopt the energy profile randomly generated for this stage of considerations.…”
