Here's an explanation of each type. 3.1.1. Type I CC-CV Charging Method This is the standard CC-CV charging method. A constant current is applied to the battery until the battery voltage reaches or exceeds the upper limit voltage set by the manufacturer (e.g., 4.2 V).
Since the voltage is constant, the charging current decreases as the battery charges. A high current value is required to provide a constant terminal voltage at anearly stage of the charging process.
Charges the battery using the maximum current until the absorption voltage is reached. At the end of the bulk phase, the battery will be about 80% charged and ready for use. Charges the battery using a constant voltage and a decreasing current until it is fully charged. See the above table for the absorption voltage at room temperature.
Generally, the CV charging method is efficient for speedy charging, but it damages the battery capacity. The negative effect is caused by an increased charging current at a low battery SOC (at the beginning of the charging process), where the current value is significantly higher than the nominal battery current.
