For normal LiFePO4 CCCV charging, I_cc is whatever the manufacturer says and V_CV is usually about 3.6V. The CCCV charging system is then similar to that for LiIon (but at lower per cell voltages) with charge termination ending when the cell determined and decreasing CV charging current falls below some present percentage of Ichg_max. Electric car charging methods The boost charger CC CV charging algorithm is a further development of the constant current constant voltage algorithms. Instead of using the constant voltage and current in the entire charging period, it boosts the charging efficiency through maximizing voltage in the first period, with the battery reaching approximately 30% of its nominal charging capacity. Li Ion BMS White Paper CCCV chargers: a false sense of ... In a small battery, the charger voltage is divided pretty much equally among the cells within it. For example, when charging a car battery, the Constant Voltage of 13.5 V is applied to the 12 V battery, each of the 6 cells within it getting about 2.25 V.
