When charging and discharging lithium-ion batteries, the current is an important factor to consider. The current flowing into the battery during the charging process determines how quickly the battery charges. A higher current means a faster charge time, while a lower current means a slower charge time.
This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process.
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
A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.
Charging properly a lithium-ion battery requires 2 steps: Constant Current (CC) followed by Constant Voltage (CV) charging. A CC charge is first applied to bring the voltage up to the end-of-charge voltage level. You might even decide to reduce the target voltage to preserve the electrode.
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.
A Designer''s Guide to Lithium (Li-ion) Battery Charging
Li-ion battery charging follows a profile designed to ensure safety and long life without compromising performance (Figure 2). If a Li-ion battery is deeply discharged (for example, to below 3 V) a small "pre-conditioning" charge of around 10% of the full-charge current is applied. This prevents the cell from overheating until such a time ...
