(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
A high charging current from 15 percent to 80 percent SOC provides fast charging, butthe high current stresses the battery and can cause battery lattice collapse and pole breaking. The main challenge for CV charging is selecting a proper voltage value that will balance the charging speed, electrolyte decomposition, and capacity utilization.
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
Constant current charging is when the charger supplies a set amount of current to the battery, regardless of the voltage. This stage is used to overcome any internal resistance in the battery so that it can be charged as quickly as possible. After the initial constant current stage, the charger then switches to a constant voltage mode.
Importantly, the DC power source ensures that it does not exceed the maximum battery voltage limit during this adjustment. The relationship between the charging voltage and the battery charging current limit can be expressed by the formula: Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm.

In pulse charging, bursts of current rather than …
Traditional Battery Charging Methods. There are four commonly used and popular charging methods: constant current (CC) charging; constant-voltage (CV) charging; constant-current-constant-voltage (CC-CV) charging; multi-stage constant-current (MCC) charging
The maximum charging rate for the Samsung Galaxy S10 is 15W(9V/1.67A) in fast charging mode and 10W(5V/2A) in normal mode. So, if I no longer have the charger it came with and I need an aftermarket, I need a charger no more powerful than 15 Watts . if I do get one higher than that, it may damage the phone.

Batteries have four main charging stages: pre-charging, constant current, constant voltage, and topping off. Pre-charging is the stage where the battery charger supplies a low current to the battery to help reduce sulfation. Constant current is the stage where the charger supplies a constant amount of current to charge the battery.
