Consider alithium-ion battery pack used in an electric vehicle. The following data is available: Heat generated by the battery (Qgen) = 500 w Ambient temperature (Tambient) = 25C = 298.15 K Battery operating temperature (7hattery)=45C=318.15 K * Cooling system efficiency (cooling) = 80% - Cooling fluid temperature (7coolant)=20C -293.15 K Calculate the following: Part 1: First Law Analysis a) Calculate the heat generated by the lithium-ion battery pack during its operation. b) Determine the energy required for cooling to maintain the battery temperature within the specified range. Part 2: Second Law Analysis c) Perform an exergy analysis of the cooling system, considering the exergy input and exergy destruction in each component. d) Calculate the exergetic efficiency of the entire cooling system.
