In current scenario importance of fuel efficient vehicles, lesser emissions & energy efficiency are the major considerations for any vehicle manufacturer. To meet these expectations vehicle manufacturer are exploring alternate powertrains to reduce emissions and produce better fuel efficient vehicles. For any vehicle manufacturer component cost, weight and package volume are the major driving factors for success. This is even true for latest upcoming hybrid and electric vehicles as well. To gain advantage and introduce products faster, OEMs are inclined to electrify their existing platforms to compete with other manufacturers. To convert existing vehicles into hybrid vehicles, all the major components like e machine, High voltage battery, power electronics etc. needs to be carefully packaged along with existing components in the same package space. This is a major challenge which needs optimum integration and packaging to ensure requirements at vehicle level and that of hybrid system level are satisfied. This paper gives an overview of the consideration of packaging the hybrid components in vehicle and integration aspects which are necessary in order to effectively integrate these components to function as a system to get the desired results.
