In this research, the flow and forced convective heat transfer analysis of HEV battery pack were investigated numerically regarding the different shapes of the inlet, outlet, and battery case. The velocity ,pressure, and temperature distribution of the fluid at the inlet part of the battery module were numerically calculated for the optimum design of the battery pack for three different inlet shapes of the battery module. In addition, the local battery temperature for height and width and convective heat transfer coefficient of the air inside the battery pack were numerically obtained. Ultimately, the circle shape of the inlet and outlet were determined for the energy-effective shape of the battery pack.

This paper is research of design and manufacture of a hybrid vehicle. Through seminar about vehicle design principle, an undergraduate students studied concept about vehicle design. Vehicle frame designed by CATIA V5. Also, composed finite element model of designed frame and executes static and dynamic analysis. A DMU model for a full vehicle was built using CATIA V5 and used to check interference between parts and to simulate assembly process. Also, in this study, applied split parallel type's hybrid system on manufacturing vehicles. Controller for system drive designed using Atmel company's AVR MCU. Through this project, the undergraduate students could acquire knowledge about vehicle development process.
