Abstract: This paper presents the overview of charging algorithms for lithium-ion batteries, which include constant current-constant voltage (CC/CV), variants of the CC/CV, multistage constant current, pulse current and pulse voltage. The CC/CV charging algorithm is well developed and widely adopted in charging lithium-ion batteries.
Conventionally, battery charging protocols must satisfy safety constraints while maximizing the state of charge (SoC) level. In the literature, both computational and experimental studies promote a diversity of algorithms, including pulse charging, multi-step constant currents, and more.
Several other studies have developed optimized charging methods to maintain maximum battery performance, such as employing artificial intelligence like particle swarm optimization algorithm on adaptive multistage constant current and constant voltage , to a combination of Fuzzy algorithms and Genetic algorithms . ... ...
In this study, a battery charging system was developed using the constant current–fuzzy (CC-fuzzy) control method. The aim is to get faster charging time and maintain battery life by limiting the battery charging temperature. The proposed charger system is dual mode which can be operated in both buck and boost mode.
There are four commonly used and popular charging methods: CC charging is a simple method that uses a small constant current to charge the battery during the whole charging process. CC charging stops whena predefined value is reached. This method is widely used for charging NiCd or NiMH batteries, as well as Li-ion batteries.
