All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged. A DC Power Supply is needed that allows for adjustable voltage and current.
You can easily recharge batteries if you have a DC power supply. All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it's fully charged.
The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current. The other two characteristics should not be used to charge batteries.
This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage controlling also known as feedback controlling.
What you want is a type of switching power supply called a boost converter. These convert a low DC voltage at high current into a high DC voltage at low current. In theory with ideal parts, they are 100% efficient. For what you want to do, real efficiency of 80% would be relatively easy.
Your current will be the highest when the battery is at the lowest voltage. – Schematic created using Current limiting is not very stable: due to its simplicity there will be small variations of the current with varying supply voltage.
