Constant Current – Constant Voltage Charging (CC-CV) is where a battery cell is charged at a constant current until it reaches the maximum charging voltage at which point the voltage is fixed and the current reduced. The following graph shows this relationship versus charge time.
It guarantees no Li-plating as E NE is constantly above 0V vs. Li/Li +. Constant Current – Constant Voltage Charging (CC-CV) is where a battery cell is charged at a constant current until it reaches the maximum charging voltage at which point the voltage is fixed and the current reduced.
Abstract: A constant power (CP)-constant voltage (CV) protocol for battery charging is implemented in a conventional boost converter with output filter (BOF) by imposing loss-free resistor (LFR) behavior during the CP phase.
Charging with a power supply requires you to set both voltage and current limits for each cell. For most lithium-ion chemistries, such as NMC Lithium battery, LCO Lithium battery, and LMO Lithium battery, you set the full charge voltage at 4.20V per cell. For LiFePO4 Lithium battery, you set the voltage at 3.65V per cell.
