“…The recovery of this energy is achieved via a generator coupled to the turbine shaft that transforms the rotational movement of the shaft driven by the exhaust gases into electricity that will be stored in batteries to be used as needed. This system can be coupled with another system to recover the energy lost during braking [12][13][14].…”

“…This function is particularly important because, by keeping the turbine at a high speed, even when the exhaust gas speed is low (throttle closed), the phenomenon of "turbo-lag" is prevented (delaying the turbine's response to acceleration pressure/throttle opening). Since the turbine is being maintained at operating speed by the electric motor, the boost pressure is therefore preserved, eliminating the "turbo-lag", so when the acceleration is pressed again, the turbine no longer needs the time necessary to increase the speed and therefore increases the pressure [11,14,20].…”

This study presents the findings of a comprehensive SWOT analysis on the integration of hybrid electric turbochargers (HETs) in mass-produced road vehicles. Through a synthesis of multiple research findings, this study compared the performance of HETs on thermal engines versus traditional turbochargers and HETs on thermal engines versus HETs on hybrid engines. The analysis highlights key strengths, weaknesses, opportunities, and threats associated with the adoption of HET technology in the automotive industry. The results of the SWOT analysis provide valuable insights for both manufacturers and consumers regarding the feasibility and benefits of adopting HET technology in modern vehicles. By elucidating the fundamental mechanics of turbochargers and demonstrating the potential of hybrid electric turbocharging, this study contributes to a deeper understanding of the role of HETs in shaping the future of automotive engineering. In conclusion, this study underscores the potential of HETs to substantially mitigate the environmental impact of the transportation sector by reducing emissions and conserving energy. The novelty of this study is reflected in its comprehensive synthesis of multiple research findings, offering insights into the feasibility and benefits of adopting HET technology in modern vehicles, thereby contributing to a deeper understanding of the role of HETs in shaping the future of automotive engineering and highlighting their continued significance, as evidenced by the systematic SWOT analysis presented. Their ability to optimize fuel efficiency and power output, coupled with the feasibility of downsized engines, positions HETs as an attractive option for sustainable mobility solutions. Further research is warranted to comprehensively understand the environmental and economic implications of widespread HET adoption.

“…In the initial stage of our research, we benchmarked two types of planetary mechanisms, i.e., 3K and 2HK planetary gears (Akiyama and Fujimoto, 2019;Fujimoto, 2020, 2022) to measure efficiency, we conducted a comparative analysis and discovered information on what sort of ratio utilized in electric cars. On the other hand, the final drive ratio of the Chevrolet Bolt is 7.05:1 (Chevrolet Bolt technical spec), while the Nissan Leaf is 7.9377:1 (Golebiewski and Lisowski, 2018). Given the above information, we developed a higher ratio and efficiency gearbox than those vehicles.…”

With the emerging trend in the production of electric vehicles, many components in the car were also modified. Instead of a large, heavy, and complex internal combustion engine, light, compact, highly efficient electric motors are now being used that are superior in terms of torque to the power plant. The main difference between the body of electric-based and internal combustion engine-based cars is the presence of a battery compartment in the electric car (most often located at the bottom of the car). Moreover, in the transmission of electric vehicles, modern electric vehicles use single-stage gearboxes instead of complex multi-stage gearboxes. In this paper, we attempted to design and test a simple single-stage transmission based on planetary gear (PG) with improved efficiency through gear profile-shift modification. Below is a detailed description of the design method of the planetary gearbox and the development process. The first candidate was the 3K planetary gear without second layer ring gear and the second was the 3K planetary without second layer sun gear. Based on the analytical evaluations, the best sample was designed in SolidWorks, its prototype was manufactured, and bench tests were performed.
