For example, a 2000mAh battery charged at 1C would use a 2A current. Charging li-ion cells at too high a current can cause the battery to overheat, while charging at a current that is too low can result in inefficient charging. 3. Li-Ion Cell Charging Voltage
When designing a single-cell Lithium-Ion charger, record the allowed maximum charge current and voltage of the battery in use. Then determine the voltage and maximum charge current of the power supply you want to use for charging. Usually, this will be five volts and between 500 mA and 900 mA (USB 2.0 and USB 3.0).
During the charging process of the battery, the short-circuit resistance also consumes additional energy, and its actual charge capacity is smaller than the normal cell. The SOC gain part is the integral of normal charge current minus the leakage current, so the estimated charge capacity will be larger than the normal cell, as shown in the ...
