Energy Profiles as a Method for Minimizing Weight of Hybrid Power Supply Systems

This article presents an analysis of energy demand by a group of portable military use appliances. This analysis was used by the author to offer an solution aimed at reducing the weight of the power supply system. This solution is based on energy profiles which were derived from the analyses and measurements, and on applying appropriately modified hybrid supply sources. Catalogue data are often used in support of an analysis of performance of electronic appliances. For a user, documents prepared by a manufacturer are the main source of information concerned with the amount and quality of electric energy sources required for the appliance to work properly. Investigations carried out in real conditions often verify this data, which provides a base for seeking alternative solutions in the course of designing new sources of power, e.g. such as the ones proposed in the article.
