Dear Experts,
I am fascinated how a cell phone battery charger knows when the battery is fully charged such that it cuts off the power to prevent further charging.
If its based on sensing a particular voltage has been reached, i wonder how is that achieved?
Or is it achieved by measuring the state of charge?
Is there a simple circuit to detect a certain voltage?
Thank you very much for reading.
Sincerely
Ramone
