The charge control IC monitors the voltage, current and temperature and performs optimized charge control tailored to the rechargeable battery with an eye towards safety and to extend battery life. Constant current charging is a method of continuously charging a rechargeable battery at a constant current to prevent overcurrent charge conditions.
The current control system is commanded by a superimposed battery voltage controller aimed at bringing the battery terminal voltage to the fully-charged state while also limiting the maximum battery charging current.
Battery charging control is another crucial and challenging part of the BMS since it can control the overcharging, overvoltage, charging rate, and charging pattern. These functions lead to a better battery performance with improved lifetime and reduced safety hazard and capacity fade risks .
A method of continuously charging the battery with a small current. Its name derives from the trickle of water. Although the charging time is longer, the advantage is that the battery is not affected even if a small current continues to flow in a fully charged state.
Bottom layer: charging current optimization: In the bottom layer, we fix the sampling step number N and let the sampling period T change with the charging time Jt given by the top layer, which can make the computational burden at the bottom layer consistent for different charging currents.
This paper presents the design of battery charging control system suitable for different battery types. A PI controller-based battery current control system is designed with the aim of achieving robust control system behavior over a wide range of battery internal resistance variations.

What you need to know about battery charge current
The battery charging current generally uses ICC. In order to protect the battery cell, it is not recommended to charge the lithium battery with a high current. If the battery is charged with a low current and a large current, it will heat up quickly and damage the battery. If you want to prolong the life, you can charge it at 0.3C. Higher (15C) charge and discharge …

You need to divide the value by 10,000 to get the charging current in Amps. To get the charging power (in Watts) you multiply the current (in Amps) by the voltage, which is almost certainly going to always be 20V. In my case: (9566 / 10,000) * 20V = 19.1W. This validated by measuring the charging rate using my Firsi USb power meter.
