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 total charging time in the CC-CV charging method varies depending on the battery capacity and the value of the charging current in the CC mode. Generally, the battery life and charging efficiency increase as the charging current decreases under the CC mode.
The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and charger circuits for use with Nickel-Cadmium (Ni-Cd), Nickel Metal-Hydride (Ni-MH), and Lithium-Ion (Li-Ion) batteries.
Intelligent charging technique is ideal for battery packs containing multiple cells because it balances the cells' SOC during charging. Consequently, compared to non-feedback-based and feedback-based methods, the batteries gain greater health, more cycle life, and higher charging capacity.
These typical approaches fall into three main groups: constant current (CC), constant voltage (CV), and constant current-constant voltage (CC-CV). The CC charging scheme is a straightforward method of charging batteries with a low, constant current to achieve a full charge at the end of the charging cycle.
For a battery pack with multiple connected cells , the intelligent charging method offers a multi-layer control structure with great flexibility that balances complexity and efficiency. This approach allows for multi-objective battery charging to be achieved simultaneously.
