Better lithium-ion batteries to the battery charging method are to provide a constant current of ± 1% pressure limiting until the battery is fully charged and stop charging. Charging voltage should be less than the maximum voltage can usually be set to 4.1V; the charge current ranges from c/2 to 1C for 2.5 to 3 hours.
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).
Understanding the correct charging profile is crucial: Constant Current/Constant Voltage (CC/CV): Most lithium batteries charge in two stages—first at a constant current until reaching a set voltage, then at constant voltage until fully charged.
Use a charger capable of adjusting charging voltage based on temperature changes. Protects lithium batteries from potential damage by accounting for variations in internal resistance during temperature fluctuations. Consider factors like capacity and charge rate to determine the appropriate charging time.
This third part of the series introduces how to correctly charge Lithium-Ion and LiPo batteries so that you can understand what you need to do when implementing a custom charging circuit. Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage.
It is recommended that lithium battery packs be charged at well-ventilated room temperature or according to the manufacturer’s recommendations. Avoid exposing the battery to extreme temperatures when charging, as this can affect its performance and life.
