The lithium battery charging algorithm consists of constant current and constant voltage stages. After the constant voltage stage, the battery should be disconnected to prevent overcharging. Periodically, the battery can receive small charges to keep it full. Figure 1 provides a visual overview of how a lithium battery is charged.
This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current. In other words, if the battery is rated at 500 mA-h, the target current is 250 mA. It is not unusual to charge at 1C (500mA), but this compromises the battery's capacity over time.
If you charge a 100Ah lithium battery with a 20A charger, the charging time is 100Ah/20A=5 hours. For smart battery charger, it will automatically choose the charging rate. When the battery is fully charged, it will switch to maintenance mode. The battery charger will caculate a time for the batteries. How Often Should Lithium Batteries Be Charged?
Fully charged battery voltage: Lithium ion Batteries: 4.2V Per Cell Lithium iron Batteries: 3.6V Per Cell Below picture to show the charging voltage difference between both.
When charging, the difference between the battery voltage and the maximum charging voltage is less than 100mV and the charging current is decreased to C/10, the battery is deemed fully charged. C depends on the battery pack or battery cell specifications. The temperature range of lithium battery charging : Lithium ion Batteries: 0~50℃
The charging current refers to the amount of electrical current supplied to the li-ion cell during charging. It’s measured in amperes (A). Typically, li-ion cells are charged at a rate between 0.5C and 1C, where “C” represents the battery’s capacity in ampere-hours (Ah). For example, a 2000mAh battery charged at 1C would use a 2A current.

During the conventional lithium ion charging process, a conventional Li-ion Battery containing lithium iron phosphate (LiFePO4) needs two steps to be fully charged: step 1 uses constant current (CC) to reach about 60% State of Charge (SOC); step 2 takes place when charge voltage reaches 3.65V per cell, which is the upper limit of effective charging voltage. …
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 ...
The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the …

Store Partially Charged: If storing your battery for an extended period, keep it at around 50% charge rather than fully charged or completely drained. Storing lithium batteries at a partial charge minimizes the stress on the battery''s chemical structure, thereby reducing the rate of degradation and extending the battery''s overall lifespan.
An easy way to charge a lithium battery is to use Microchip''s MCP73827 lithium charger IC. The MCP73827 biases an external p-channel MOSFET to provide power to the lithium cell. The MCP73827 senses voltage across a low-ohm sense resistor sensed to regulate the charge current for constant current charging and charge termination. The MCP73827 ...
The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete.
