Что ты имел в виду? Я не понял?

it's not bad for (10A - 15A ) charger but it's not very smart, known that if the charger connecting to the battery both battery and charger have the same voltage so its no problem if the transistor voltage gives from the charger. at first when you charge the battery the voltage path through the relay if a battery is fully charged not charging else charging it until fully charged. if you want to make a smart charger you can use LM324 and regulate the voltage at 13.7v for large current and 14,4v for normal current.

Alaikuma salam wa rahmatullah wa barakathu. Thank you

dear I said its is only a simple . before i build a DC to DC converter it the best efficiency for a make a good wireless charging. In secondary coil if you use a diode and capacitor you can make a DC
