“…The charging strategy is an extended version of standard CC-CV which starts with CC charging until the battery voltage reaches a predefined voltage, and then the battery will be charged with another different predefined voltage until the charging current falls to cut-off current. The phase-locked loop (PLL) control [122] is also adopted to improve CC-CV charging performance. In Ref.…”

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.

“…In [11] and [12], a sinusoidal-ripple current charging strategy is proposed; this approach can minimize the battery impedance and consequently maximize the energy transfer efficiency. The reason for using pulsed charging and sinusoidal current charging technique is that the internal pressures obtained by pulsed charging and sinusoidal current charging are smaller than that obtained by CC charging [6][7][8][9][10][11][12]. However, these methods require dedicated hardware to generate pulsed or sinusoidal charging current.…”

Lithium ion (Li-ion) batteries have been widely used in various kinds of applications, including consumer electronics, green energy systems and electrical vehicles. Since the charging method has a significant influence on the performance and lifetime of Li-ion batteries, an intelligent charging algorithm which can properly determine the charging current is essential. In this study, a fuzzy-logic-control-based (FLC-based) five-stage Li-ion battery charger is proposed. The proposed charger takes the temperature rise and the gradient of temperature rise of battery into account, and adjusts the charging current accordingly. To further improve the performance of the proposed FLC, the fuzzy-based Taguchi method is utilized to determine the optimal output membership functions (MFs). Comparing with the conventional constant current-constant voltage (CC-CV) method, the charging time, charging efficiency, average temperature rise and the obtained cycle life of the Li-ion battery are improved by about 58.3%, 1.65%, 26.7% and 59.3%, respectively.

“…Among them, the CC-CV is used most widely, but its performance is still unable to meet the users' needs. Consequently, the fuzzy control, neutral network, genetic algorithms, ant algorithms, and grey prediction are applied to obtain better battery charging performance [2]- [6].Besides, phase-locked loop technique was also adopted to achieve the purpose of high performance and low cost [7]- [9]. Recently, the advanced battery charging systems have used the pulse current/voltage pattern to obtain an evener distribution of ions in the battery electrolyte to advance the charging performance [9]- [17].…”

This paper aims to explore the optimal charging frequency of the LiFePO 4 battery by the analysis of the AC impedance. The experiments show that the optimal charging frequency is at the minimum AC impedance frequency. In such a condition, the LiFePO 4 battery charging time and charging efficiency are improved about 5.6% and 6.8%, respectively. In addition, the increased temperature of the battery can be slowed down about 6.3℃, the aging phenomenon of the LiFePO 4 battery can be reduced, and then the battery life cycle can be prolonged.
