1. Overview: 2. Research Background: The increasing global demand for environmentally friendly automotive manufacturing necessitates lightweighting techniques to address the weight increase associated with electric vehicle (EV) batteries. Volvo Cars is investing in large-scale casting (Mega-casting) using High-Pressure Die Casting (HPDC) to simplify assembly, improve efficiency, and enhance product quality. However, mega-casting presents challenges related
1. Overview: 2. Research Background: The increasing need to reduce CO2 and SO2 emissions due to climate change necessitates improvements in electric vehicle efficiency. While Brushless Direct Current (BLDC) motors are widely used in EVs due to their high power density, efficiency, and reliability, their operational lifespan is limited by high internal heat generation and
1. Overview: 2. Research Background: High-performance conductors are essential for economically and environmentally sustainable electricity transfer in modern infrastructure, manufacturing, and transportation, including electric vehicles. While copper has been the traditional conductor of choice, aluminum offers significant advantages in terms of cost and weight reduction for electricity transmission and distribution. Over 14% of global aluminum
1. Overview: 2. Research Background: Induction Motor (IM) drives are a crucial technology in modern industry, powering various applications including material handling, food and beverage processing, and electric transportation systems like EVs and e-trucks. Recently, there’s a growing focus on high-efficiency IM drive systems to reduce energy and fuel consumption, aligning with global sustainability initiatives.
1. Overview: 2. Research Background: The research addresses the growing global energy demand, projected to increase by 33% by 2050 [1]. A significant portion of energy is wasted as low-grade waste heat in industries like manufacturing and power generation [2, 4]. Conventional waste heat recovery (WHR) methods using heat exchangers often face challenges such as
1. Overview: 2. Background: Heating, ventilation, air-conditioning, and refrigeration (HVAC&R) systems consume a significant portion of residential and commercial building energy. Reducing refrigerant charge to mitigate greenhouse gas emissions is a crucial objective. Traditional heat exchangers (HXs) using round tubes and fins have limitations in performance improvement and require further miniaturization to meet reduced refrigerant
1. Overview: 2. Research Background: The increasing use of LEDs in automotive lighting systems presents a challenge due to heat generation from high-power LEDs, leading to performance degradation and reduced lifespan. Previous research identified factors affecting LED lifespan and analyzed heat transfer characteristics through heat sink design modifications. However, these studies lacked optimal cooling system
Qi-gui Wang, Andy Wang & Jason Coryell Abstract Ultra-large aluminum shape castings have been increasingly used in automotive vehicles, particularly in electric vehicles for light-weighting and vehicle manufacturing cost reduction. As most of them are structural components subject to both quasi-static, dynamic and cyclic loading, the quality and quantifiable performance of the ultra-large aluminum shape castings is critical
