Abstract: Energy hybrid systems are key elements in automotive, that meet the energy demands of traction engine, provide a convenient life and present a minimum weight and volume. Supercapacitors are devices able to meet specified demands, especially when they work together with the other energy sources, such as batteries.
Present research aims to develop an energy hybrid system for transport, using batteries and supercapacitors, in order to optimize it’s energy management. To achieve this goal, several steps are taken in account.
Based on a synthetic analysis on superacapacitors, models are developed and determinations are carried out, to characterize and determine the type of supercapacitors pack to be used in the proposed applications.
Two architectures of hybrid energy systems are presented and their operating regimes are detailed. Mathematical modeling is carried out, models for the components and for the two hybrid systems being obtained.
The final part is intended to simulation and experimental tests, done for both traction applications proposed. Through the data results, supercapacitors contribution is underlined by a comparative analysis of main parameters provided by simulations and experiments too. The energy management is also presented, in a traditional system with batteries and in a hybrid system that contains supercapacitors and batteries.
