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.
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.
Batteries are direct current ‘DC’ and only push the current in one direction. An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC power. They use a AC to DC power supply to allow us to charge the device by plugging it into the wall.
There's a lot of DIYs that utilize DC/DC converters to charge Lithium batteries. A quick Youtube search shows dozens of these DIYs. I was wondering how these home-made chargers work. Yes, DC/DC converters do provide constant voltage and constant current, but the mechanism of battery chargers isn't exactly the same?
Because of difficulties in detecting full charge with nickel-based batteries, I recommend charging only lead and lithium-based batteries manually. Before connecting the battery, calculate the charge voltage according to the number of cells in series, and then set the desired voltage and current limit.
For example: Let's say we have a 10s 10 Ah Li-ion battery pack with a nominal voltage of 37 V and full charge voltage of 42 V. Now, charging this pack using DC/DC converter that could supply constant voltage of 42 V and let's assume we charge the battery at 0.2C which means 2 amps.
Then, set the limit of your power supply [limit the current]. Now, figure out the charged voltage of your battery. It''s generally 3.2V per cell for the LiFePO4 battery. Finally, …
