I have gone through various materials online to understand the concept of trickle charging and other types of charging. I have a few queries which were not clarified.
From what I understand, trickle charging helps the battery to reach 100% by providing very low current upon reaching 90-95% of the battery level. So, it always provides some amount of current despite the charge level of the battery, right?
My query :
Is trickle charging property of the charger that I plug into the wall socket and connect to the phone? Or is the property of the phone to support trickle charging? Is the charger an intelligent device to provide trickle charging? From what I observed, chargers only have power components and circuitry to deliver the required amps at the mentioned voltage, say 5V.
Can someone also help me to understand what is Float charging? From what I understand from the Wikipedia section on float charging, it charges to the required battery voltage continuously at the mentioned voltage and the current and then stops upon reaching 100%. After the battery drops to some threshold (which is set by the phone or the charger ? please tell this ), say 95%, the charger wakes up and provides charge to increase the battery to 100%? Am I right?
How is fast charging different from the above two types of charging? Are there any other types of charging apart from this?
Please help me understand my queries.
