“…Further, the company maintains its debt at 1.007 times equity and has maintained an excellent debt-to-equity ratio. Toyota should increase efficiency in its production of vehicles to minimize recalls and focus more on affordable and fuel-efficient models in order to capture more market share from General Motors and Tesla, which are already well established in the industry with a 15% market share each in the US [14,15].…”

Toyota is the world's largest car manufacturer. It has a chain of companies that provides inputs and services to manufacturing, distribution, and sales. Toyota sells 8 of the world's 10 best-selling cars and it holds a 14% share in the US, its biggest market. By analyzing from swot model, the Toyota Motor Corporation has a high level of brand recognition and market share in more than 170 countries. Additionally, Toyota needs to manufacture more efficient vehicles in order to avoid frequent recalls; it is an expert in the high-end car market but should introduce more cost-efficient/fuel-efficient choices. assess its market value using the approach. Through a multiple-method valuation analysis, it can be seen that Toyota is an overvalued company: it uses cost and pricing strategies that have some instructive value but are still threatened by several challenges in the future auto industry. Therefore, to maximize profits and ensure sustainable growth, Toyota should leverage opportunities in global markets to strengthen production while capturing strategic value chain essentials. A key factor is developing an information technology strategy for the supply chain to reduce operating costs, improve profitability and better respond to future trends in the automotive industry.

“…The CC regulates the current ripple across the L-C filter to achieve improved performance efficiency, much like the DC/DC boost converter. For the Toyota Prius, a modified CC is proposed with tuning and filtering “proportional–integral (PI)” controller (Balachander et al, 2021). The real-time execution of this converter is debatable because the traditional PI controller has a number of performance degradations, including slow transient response, excessive overshoot, manual tuning, and inadequate filtration.…”

Electric vehicle technology has recently drawn a lot of interest on a global scale due to improved performance in its efficiency and the capability to solve the problems of carbon emission. As such, electric vehicles are the key to achieving sustainable development goals. This review article analyzes deeply the previous technical developments of electric vehicles, focusing on important topics like battery management systems, technologies of power electronics, techniques of charging, and the relevant algorithms and improvements. In addition, several critical problems, and difficulties are presented in order to pinpoint the gaps in the literature. To address the analysis of battery behavior, battery condition monitoring, real-time control design, temperature control, fault diagnostics, and efficiency of battery model are considered. This study highlighted the estimation techniques that predict the internal battery conditions such as internal temperature, state of health, and state of charge, which are difficult to be directly monitored and determined. A lithium-ion battery, a super-capacitor, and related bidirectional DC/DC converters constitutes the infrastructure of a hybrid power system. This review offers useful and practical recommendations for the future development of electric vehicle technology which in turn help electric vehicle engineers to be acquainted with effective techniques of battery storage, battery charging strategies, converters, controllers, and optimization methods to satisfy the requirements of sustainable development goals. Accordingly, this review article will be a platform and future guide for those who are interesting in the field of energy management and its development.

The voltage output of an energy storage device utilized in electric vehicles (EVs) is modulated in response to the load, and the elevated voltage of the DC link poses challenges for vehicle engineers when integrating energy storage components with the traction drive system. DC-DC converters are commonly employed in electrical powertrain systems within industrial settings to facilitate the integration of various components. The Cuk converter is widely acknowledged as a viable alternative requiring thorough deliberation, including battery management systems (BMS) for EVs technology. This is because of a continuous flow of current in both the input and the output, and it has a high efficiency compared to the buck-boost topology. Additionally, there is a low ripple in the output load voltage. The present work uses an analysis, model, and control of the Cuk converter circuit using a hybrid fuzzy logic-based ant colony optimization (ACO) method. The transient response and the steady-state performance specifications are objective functions in the fuzzy controller design process. After a comprehensive evaluation of the obtained results, it was observed that the fuzzy-ACO controller successfully achieved the desired reference with reduced rise and settling time. This study implements modeling and controlling applications of the Cuk converter by utilizing the MATLAB/SIMULINK program. The proposed controller's effectiveness is demonstrated during load variations and changes in the reference voltage.
