Nov 26, 2024 · I have a 30• year old battery charger/ starter I would like to get working. The transformer has 8 metal lines coming out of it that plug into a steel plate that the positive charger cable attached to. I assume each pair are for the 4 different amperage settings of the charger. I assume I could...

Nov 19, 2024 · My focus research area is on Battery chargers. I would like to know the part for Constant Current charging. As i have done a sample circuit for the CC-CV battery charger system. I have conducted a few testing and simulation for the circuit but did not achieve CC-CV profile in the simulation. I am going to charge a 3.7V 3A 5000mAh battery.

Jan 30, 2025 · The charger will supply what it is able to, so using a 10A charger on a battery that has a lower maximum charge current (eg 7A) means it will be delivering excessive current. Neither of the chargers you show seem very capable. Modern automatic chargers can provide the three-stage charging regime that best suits lead-acid cells. The chargers you ...

Sep 17, 2008 · For rectifier diodes in a battery charger, practically any diode with at least the current and voltage ratings of the original diodes will do. You can use any diodes with higher current and voltage ratings without concern and with some added insurance against failure, but I wouldn't spend much extra money to do that.

Nov 22, 2024 · I'm going to make a battery pack charger. We will use 18650 cells, so the cc-cv charging method should be implemented. Based on the batteries for electric bicycles I am thinking of using a total of 40 cells with 18650 cell 10S 4P. The 18650 cell had a full-charge voltage of 4.2V / a rated voltage of 3.6V / a discharge end of 2.65

Feb 6, 2024 · The removal of the battery means the battery voltage is no longer opposing the charger supply voltage, so there is 1.45V more voltage across the resistor which, from Ohm's law, increases its current. If you want the current to be independent of the battery voltage, you will need an active-circuit (transistors, etc.) constant-current source.
