Battery Management Systems–Part 3: Battery Charging Methods
CC-CV charging was initially used to charge lead-acid batteries and, later, to charge Li-ion batteries. Li-ion batteries require a much longer CC mode. The CC-CV charging method is more efficient than either the CC or CV methods individually, and as such it is used as the reference for comparison with the latest charging methods.
