Flash battery charging is a total solution that can be seen in Figure 3. It has two low R DS(on) field-effect transistors (FET) in the power circuit to reduce the conduction loss. The purpose of using two back-to-back FETs instead of one FET is to avoid the backflow from the battery to the adapter side.
A low-profile, high-current, and low-loss inductor is another major hindrance for high-current battery charging. The flash charger is a system-level solution. The output voltage of the adaptor is adjustable based on the battery voltage and charging current, so the traditional 5-V or 9-V adapter could not be used. The 5-V or
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging
Charging a lithium-ion battery involves precise control of both the charging voltage and charging current. Lithium-ion batteries have unique charging characteristics, unlike other types of batteries, such as cadmium nickel and nickel-metal hydride.
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
