“…The Taguchi-based method is another effective approach to search the optimal MCC charging pattern. Liu et al [128] presented a Taguchi-based approach to accelerate charging speed and prolong cycle life for a Li-ion battery. A fivestage MCC charging pattern is optimized by the consecutive orthogonal array technique.…”

Batteries have been widely applied in many high-power applications, such as electric vehicles (EVs) and hybrid electric vehicles, where a suitable battery management system (BMS) is vital in ensuring safe and reliable operation of batteries. This paper aims to give a brief review on several key technologies of BMS, including battery modelling, state estimation and battery charging. First, popular battery types used in EVs are surveyed, followed by the introduction of key technologies used in BMS. Various battery models, including the electric model, thermal model and coupled electro-thermal model are reviewed. Then, battery state estimations for the state of charge, state of health and internal temperature are comprehensively surveyed. Finally, several key and traditional battery charging approaches with associated optimization methods are discussed.

“…The factors were composed of level 3, depending on the maximum and the minimum of each factor. Among the signal-tonoise (SN) ratios used to effectively estimate the effect of the noise factors on the process characteristics, thesmaller-the-better characteristic SN ratios−which correspond to the minimum of the objective function− were used to analyze the contribution ratio of each factor to the changes in the end-cogging-force magnitude [10][11][12][13]. A greater contribution ratio indicates a greater change in the objective function as the level of the factor changes.…”

Although the initial cost of permanent-magnet linear synchronous motors is high owing to the installation of armatures over the full length of the transportation lines, linear motors are useful for transportation systems because of their high speed, acceleration, and deceleration. For these reasons, research into reducing the cost of linear motors is necessary, and a stationary distributed-armature system has been suggested for installing armatures in sections where acceleration and deceleration of the mover are required. However, each armature has ends that significantly increase the cogging force, resulting in the increase in the thrust ripple of the mover. Therefore, in order to improve the thrust ripple of the system, the present study aims to provide auxiliary teeth on both ends of the armature to achieve an optimal design through an analysis of the contribution ratio with respect to factors regarding the design of the experiment and the objective function.

“…Each step has an effect on the charging time and battery lifetime. Several techniques have been introduced to improve the cycle life [5] ~ [8]. However, although these works are effective, they are all focused on the single type of EES elements or homogeneous EES systems.…”

“…This metric captures the general condition of the EES elements and their ability to store and deliver energy compared to its initial state (i.e., compared to a fresh new EES element). Some researchers have worked on extending the lifetime of EES elements [5]~ [8]. However, they only focus on either a single EES element or a homogeneous EES system, which consists of a single type EES element array.…”

-This paper is the first to present an efficient charge management algorithm focusing on extending the cycle life of battery elements in hybrid electrical energy storage (HEES) systems while simultaneously improving the overall cycle efficiency. In particular, it proposes to apply a crossover filter to the power source and load profiles. The goal of this filtering technique is to allow the battery banks to stably (i.e., with low variation) receive energy from the power source and/or provide energy to the load device, while leaving the spiky (i.e., with high variation) power supply or demand to be dealt with by the supercapacitor banks. To maximize the HEES system cycle efficiency, a mathematical problem is formulated and solved to determine the optimal charging/discharging current profiles and charge transfer interconnect voltage, taking into account the power loss of the EES elements and power converters. To minimize the state of health (SoH) degradation of the battery array in the HEES system, we make use of two facts: the SoH of battery is better maintained if (i) the SoC swing is smaller, and (ii) the same SoC swing occurs at lower average SoC. Now then using the supercapacitor bank to deal with the high-frequency component of the power supply or demand, we can reduce the SoC swing for the battery array and lower the SoC of the array. A secondary helpful effect is that, for fixed and given amount of energy delivered to the load device, an improvement in the overall charge cycle efficiency of the HEES system translates into a further reduction in both the average SoC and the SoC swing of the battery array. The proposed charge management algorithm for a Li-ion battery -supercapacitor bank HEES system is simulated and compared to a homogeneous EES system comprised of Li-ion batteries only. Experimental results show significant performance enhancements for the HEES system, an increase of up to 21.9% and 4.82x in terms of the cycle efficiency and cycle life, respectively. Keywords: hybrid electrical energy storage system, charge management, state of health.
