"Professional" battery SoC calculation is done by integrating the area under the current-vs-time curve, essentially to count how many coulombs of energy is going into or out of the battery, & comparing that to either (a) the theoretical/designed coulomb capacity of the battery, or (b) keeping track over long periods of time how many coulombs ...
How Does Windows Detect Battery Problems?
It also can derive information from the charging cycle itself: The time it takes to reach full-charge at a given voltage/current changes when the battery gets worn out. (Voltage drop during discharge is not reliable as it depends a lot on the amount of current drawn while discharging, so it varies with the use-pattern of the laptop.)
10 Bad Alternator Symptoms to Watch, Listen and Smell For
Wires within the alternator cut through a magnetic field; this in turn induces electrical current. That current is used to power your car''s electrical system, which can be anything from headlights to the electro-hydraulic lifts on a snow plow. The alternator also keeps the battery fully charged, providing the power it needs to start the car.

battery
The charging rate is current, which is in Amps. 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.
