| Summary: | 碩士 === 國立雲林科技大學 === 環境與安全衛生工程系 === 106 === Under the pressure of oil shortages and environmental protection issues, the rapid development of electric vehicles (EVs) and hybrid electric vehicles (HEVs) has substantially increased the demand for high-energy rechargeable battery packs. The lithium battery (LIB) module inside the EV is the key to the success of the development. However, heat generation and accumulation of LIB modules are vital in safety issues during the operating process of EVs and HEVs. The thermal management is extremely crucial, ensuring the safety and continuous power supply of LIB modules. In this study, the forced-air cooling system was used to conduct the research on heat dissipation. The main work is the design of the carrier, the wind speed, and the energy consumption of the wind turbine. From the above-mentioned, we could find the optimal feasible program for the cooling system. In addition, the battery module arrangement design was added. As planned, the adiabatic calorimetry was applied to evaluate the total heating behavior during the operation of the battery. The method can calculate how much heat requires to be taken away from the environment to keep the battery module within a safe range (<55 °C). Combination of a various thermodynamic parameters and heat transfer models was based on the derivation of the effectiveness of various cooling cases. Combining the results of α, β, ΔT and η, the case 1 with a cooling air of 3.0 m/s in the compact cooling system is the best design of this study.
