How to charge a lithium polymer battery?

The high current charge is fast, but if the current is set too much, it is more dangerous. The charging current for lithium polymer batteries is generally set at 3-5A. After completing the above settings, click “Start Task” at the bottom to start charging. During the charging process, the current and the voltage of each cell can be seen.

Why is it important to charge lithium polymer batteries correctly?

It is crucial to charge lithium polymer batteries correctly to ensure optimal performance and longevity. By understanding the characteristics of these batteries and considering various factors such as voltage, current, and temperature during charging, you can maximize their efficiency and lifespan.

How do you charge a lithium battery?

Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.

How to correctly charge lithium-ion and LiPo batteries?

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.

What is a lithium polymer battery?

Lithium polymer batteries, commonly known as LiPo batteries, have become increasingly popular in recent years due to their high energy density and lightweight design. Unlike traditional lithium-ion batteries, LiPo batteries use a gel-like electrolyte instead of a liquid one, making them more flexible and less prone to leakage.

How does A PMIC charge a lithium ion battery?

Typically, PMICs charge LiPo and Lithium-Ion batteries using the CC-CV method. The battery gets charged with a constant current until the cell reaches its maximum voltage. From then on, the charger gradually decreases the charge current until the battery is fully charged. Modern charge ICs apply a few more steps to the process to increase safety.
