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.
The standard charging protocol for lithium-ion batteries is constant current constant voltage (CCCV) charging. In addition to this, several alternative charging protocols can be found in literature. Section 2 will provide an overview on the different categories of charging protocols and their specific characteristics.
Our experimental cycle life study on charging protocols for lithium-ion batteries has shown that a sophisticated study design is essential for separating the effects of different parameters on the performance of charging protocols.
Experimental results show that this method can effectively measure the actual voltage of lithium-ion battery under different rated voltages, and the measured voltage waveform is very stable and almost without distortion.
As the CCCV protocol is the standard charging protocol for lithium-ion batteries, it serves as a baseline in our study. For all three cell models examined our study, the CCCV protocol is the charging procedure recommended by the manufacturer. Extensive parameter variations were performed for the charging current Ich and the charging voltage Vch.
