When does a CC-CV battery switch to constant voltage?
The charging switches to constant voltage (4.2 V) when the battery’s internal voltage exceeds or equals 4.2 V. The process concludes when the charging current drops below 0.05 C. Figure 13 and Figure 14 illustrate the charging profile and flowchart of the Type III CC-CV charging method.
What happens when a battery is charged in constant voltage mode?
During the constant voltage mode, the charging current starts to decrease. When the charging current drops to a predefined minimum current value (e.g., 0.05 C), the charging process concludes, indicating the battery is fully charged (e.g., battery state of charge is 100%).
What is phase transition in Li-ion batteries?
Li-ion batteries: Phase transition. Chinese Physics B , 2016, 25 (1): 016104 1. Introduction The phenomenon of phase transitions and the resultant phase diagrams in Li-ion batteries (LIBs) are often observed in the synthesis of materials, electrochemical reaction processes, temperature changes of batteries, and so on.
