How Does A Lithium Ion Battery Charger Work?
Lithium-ion battery chargers use a CC-CV protocol (Constant Current-Constant Voltage) to safely charge cells. Initially, a fixed current (e.g., 0.5C–1C) is applied until voltage per cell nears 4.2V (for NMC). Then, voltage is held constant… How Does A Lithium Ion Battery Charger Work?
