FUNDAMENTALS
What is CC/CV Charging and Why It Matters
Constant Current / Constant Voltage (CC/CV) is the universal charging algorithm for lithium-based batteries. During the CC phase, the charger delivers fixed current while voltage rises. When voltage reaches the threshold (e.g. 4.2V per cell for Li-ion), the charger switches to CV mode, holding voltage steady while current tapers to near zero — signaling full charge.
Why it matters: Overcharging Li-ion cells causes electrolyte decomposition and thermal runaway. CC/CV prevents this by precisely terminating charge current at the right threshold, extending cycle life by 20–40%.
