Is there a relation between the voltage and the time of charging needed to fully charge a rechargeable battery?
Okay, the situation is we’re gonna go charge a battery at different voltage and of course at different currents. Now I want to know if there’s a relation or some sort of a formula, I just want to confirm the results, thanks.
As a battery (or a cell) has a certain terminal voltage, dependent on the type of battery, the voltage you charge it with should exceed the terminal voltage by a small amount – enough to get current to flow into the battery. Using excess voltage when charging can cause excess current to flow into the cell and damage it – the parameter that determines the charge time is current. The amount of electrical “charge” is directly proportional to current * time (Q=It) – so concentrate on current control.
