Abstract
The Hybrid electric vehicle (HEV) has become one of the most promising vehicles in the automobile industry due to its energy saving ability and low emission of harmful pollutants. Battery management system, which has acceptable life cycle, remains the major roadblock to large-scale production of Electric vehicles and Hybrid electric vehicles, which consists of high power density batteries. In the last few years the pollution problems and the increase of the cost of fossil energy (oil, gas) have become planetary problems. The car manufacturers started to react to the urban pollution problems in nineties by commercializing the electric vehicle. But the battery weight and cost problems were not solved. The batteries must provide energy and peaks power during the transient states. These conditions are severe for the batteries. To decrease these severe conditions, the super capacitors and batteries associate with a good power management present a promising solution. Simulink, a model is a collection of blocks which, in general, represents a system. This paper emphasis more on the management of the energy provided by super capacitor Packs. Each super capacitors module is made of 108 cells with a maximum voltage of 270V. The multi boost and multi full bridge converter topologies are tested to define the best topology for the embarked power management.. The experimental and simulated results validate the proposed two converter topologies presented in this paper.
