"CV" stands for "constant voltage", and "CC" stands for "constant current". Most types of load need constant voltage to operate, so if the "CV" LED is lit, it means the PSU works fine with your load. The PSU has a physical limit on how much current it can supply. 14. WHY IS CHARGING WITH CCCV BAD? Qnovo The higher the charging current, the faster the charging time; and consequently, the higher the power; and therefore, the bigger the AC adapter (or wall charger) to accommodate the higher power rating. That’s why a tablet adapter, typically rated around 12 Watts, is bigger than a typical smartphone adapter which is rated at or near 5 Watts. Battery Chargers and Charging Methods Constant current Constant voltage (CC CV) controlled charge system. Used for charging Lithium and some other batteries which may be vulnerable to damage if the upper voltage limit is exceeded. The manufacturers' specified constant current charging rate is the maximum charging rate which the battery can tolerate without damaging the battery.
