A novel controller design for a pure battery electric vehicle

M.Ing.Abstract: This dissertation presents a new controller design for a pure battery electric vehicle (PBEV), which is intended for future electric vehicles’ (EVs) internal power grid circuit. EVs with a direct current (DC) power grid as well as a battery storage system (BSS) are the subject of this dissertation. Research on EVs has accelerated in the automobile sector. The technology relies on engineering and energy storage with revolutions in these areas, resulting into an adequate improvement of EVs. The development and use of EVs are rising daily regardless of excessive investment costs. However, the EV system has a problem, namely storage and production of energy. Recent trends in EVs have led to the provision of solution in terms of relatively significant transfer of energy within a short period to the power grid of EVs. The introduction of EVs has gained prominence mainly because of their environmentally friendly advantage over internal combustion vehicles (vehicles with petrol/diesel engines) as they emit less pollutants. In the transportation sector, there are three different types of EVs developed to minimise the environmental pollution issue. These are: hybrid EVs, plug-in-hybrid EVs and PBEVs. The varieties of drives used for EVs encompass AC induction motors, switched reluctance motors, permanent magnet synchronous motors (PMSM), brushless direct current motors (BDCM) and brushed direct current motors (BDCM). The literature review in this work focused primarily on the analysis of DC-DC converters, electric motors and solar energy, which received increased interest and more meticulous study
