In the initial stage of charging when the battery voltage is low, charging is performed at a constant power, and when the battery is close to full charge, operation switches to CV charging to prevent overvoltage conditions.

Unlike other types of batteries, such as cadmium nickel and nickel-metal hydride, lithium-ion batteries have unique charging characteristics.
A high charging current from 15 percent to 80 percent SOC provides fast charging, butthe high current stresses the battery and can cause battery lattice collapse and pole breaking. The main challenge for CV charging is selecting a proper voltage value that will balance the charging speed, electrolyte decomposition, and capacity utilization.
