Traditionally, the current rate (C-rate) influences the performance-degradation behavior of LIBs. Thus, the charging method impacts the performance and lifetime parameters of the LIB . On the other hand, the battery discharging is determined by the consumer's energy consumption behavior.
The battery charging process can be divided into two phases according to the variation of the charging current at different phases. In the first phases, the corresponding temperature rise increases at a large charge current, to meet the constraints of the charging conditions. As the temperature rise is reduced, the charging current decreases.
