“…Due to the CC in the respective stages, the battery can be charged faster than with the compared CCCV profile. Research has shown that a charge time reduction of up to 12% can be achieved (Khan, 2016). However, since the current is not continuously reduced, the CC in the different stages will result in a higher overall battery temperature and thus promote ageing and lithium-plating (Keil and Jossen, 2016;Shen et al, 2012).…”

This comprehensive overview of the impacting factors on lithium-ion-battery’s (LIB) overall efficiency presents the most relevant influencing factors on a battery’s performance. Dissected into their respective short-term and long-term influences, the working principles behind the efficiency influencing factors are presented. With a strong focus on battery characterisation, charge-profiles and battery management systems (BMSs), the authors present results of their own practical research with a detailed literary analysis, allowing a broad coverage of the complex topic. Finally, the authors present a principle model that indicates the interactions between the different involved components of the battery.

“…Liu et al [130] proposed an MCC charging approach with various weights in each stage based on an internal-DC-resistance (DC: Direct current) model to balance the conflicts between charging speed and energy loss during charging process. Khan et al [131] presented a unique approach to search the optimal MCC charging pattern by using equivalent circuit model for Li-ion battery. The three and five CC stages are both discussed based on the optimal pattern to improve the charging speed and efficiency.…”

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.

“…This phase ends when the battery voltage reaches the maximum specified by the manufacturer. For Li-ion batteries the maximum voltage is usually in the range of 4.1-4.3 V depending on the type of battery (Khan et al, 2016;Luan et al, 2011). b) CV phase: The charged battery is connected to the CV charging source with a voltage value of maximally allowed battery voltage.…”

“…Charging current starts to decrease. This phase ends when charging current, which flows to the battery, is only 0.01 C. This second phase is not always desired, because it can add only about 10% of capacity to the battery, but it stresses the battery and thus slightly reduces lifespan (Khan et al, 2016;Luan et al, 2011).…”

The paper presents an approach to the modelling of a cyclic battery tester and contains observations about lithium-ion (Li-ion) batteries, charging/discharging procedures, conditions and protections which must be observed during the testing process. The main goal was to create and simulate a schematic which will be capable of cyclically testing Li-ion battery cells. Regulation of the final schematic is based on cascade connections of operation amplifiers, which work as a voltage source with current-limiting functions. The power part is created by two MOSFETs connected as a half-bridge. This topology allows current to flow in both directions (from and to the battery). Final simulation is supplemented by protections such as reverse polarity protection, short circuit protection and overvoltage protection during charging. Proper operation of the whole connection is demonstrated by the simulation outputs in the final section.
