The charging current depends directly on the capacity of the battery, all other things being equal. When you read literature about batteries, you will come across C-rate. For example: "The battery was charged at 0.5C ." It's not temperature in Celsius, and it's not capacitance in Farads.
So, let’s start learning about the very important concept of “Battery Capacity”. Battery Capacity is defined as the product of the electric current flowing in or out of the battery in amperes and the time duration expressed in hours. Battery Capacity influences the time for which a device can operate without using power from any other sources.
(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.
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.
For instance, consider a battery with a capacity of 50 kWh. If it’s charged at a 1C rate, it’s charged at a rate that fills the battery’s full capacity in one hour, so 50 kW. Charging at a higher rate, like 2C, would mean it charges in half the time, i.e., 30 minutes, with a power output of 100 kW.
The energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
