In fact, the internal charging mechanism of a lithium-ion battery is closely tied to the chemical reactions of the battery. Consequently, the chemical reaction mechanisms, such as internal potential, the polarization of the battery, and the alteration of lithium-ion concentration, have a significant role in the charging process.
Pulse charging and sinusoidal AC charging with an optimal charging frequency may be suitable for charging a large capacity and high voltage battery system. However, the effectiveness of those charging methods for some Li-ion batteries has been challenged recently, thus more statistical validations are required in the future study.
In their study, following a multi-module charger, a user-involved methodology with the leader-followers structure is developed to control the charging of a series-connected lithium-ion battery pack. In other words, they are exploiting a nominal model of battery cells.
The expanding use of lithium-ion batteries in electric vehicles and other industries has accelerated the need for new efficient charging strategies to enhance the speed and reliability of the charging process without decaying battery performance indices.
Another research that employed a PC approach for charging lithium-ion batteries is described in , in which the lithium saturation is avoided by correctly selecting the parameters, allowing significantly higher rates of charging.
However, wide deployment of Li-ion batteries in EVs has been greatly restricted by their existing charging strategies [6, 7]. To address this issue, the research on the provision of an optimal charging method to Li-ion batteries has emerged as a new paradigm towards a smarter battery management system (BMS) [8, 9].
