{1133} Ebike / Electric Bike Battery Charger Repair

in this video {1133} 48V Ebike / Electric Bike Battery Charger Repair, i demonstrated how to repair LNYAQA LY88-001 T/TCDZ0001-2019 it is 48V12AH battery charger, it is not powering on. it is using UC3842 ic as smps controller. in secondary side it is using LY03 and LM38 IC as battery management system

You should have changed the 4th bridge rectifier diode also. Since all other diodes and mosfet are short circuited and whatever caused that to happen such as a high voltage spike/high inrush current must have flown through the 4th diode also and must have barely survived from becoming short. There still a high chance that the diode will eventually fail when compared with the other 3 diodes

Hvala Hasebe, ova oblast punjača baterija danas je mnogo zastupljena, i mnogo nam znači tvoje objašnjenje i praktični rad !

Weldon keep sharing this informative video

sir, thank you for uploading, I already have a reference for repairing my ebike charger

Poškozené jsou všechny čtyři diody je dobré je vyměnit všechny nebude dlouho trvat a tento zdroj bude opět na opravě nedávno jsem o této problematice natočil video na můj kanál. Dioda sice vypadá že je v pořádku ale její průrazné napětí se sníží až na třetinu. Při mém testu dioda která měla vydržet 1kV zvládla pouze 350V tudíž by netrvalo dlouho a došlo by k poškození i této diody. Multimetr nedokáže měřit takto vysokým napětím tak proto se nedá zjistit poškození v závěrném směru. Mám rád tvá videa hodně mě naučila pokračuj ve své práci a zkus změřit tu funkční diodu a prosím neber tento komentář špatně je to pouze rada. Děkuji

Great job ! But how do you know the value of the dead zener diode ?

[mehranmohamad]

hi good time. how did yiu find out the type of zener diode in the mosfet gate drive and how did you choose a similar type of diode?

[mallipushpa]

Good evening nice experience Diod fuse mosfet3, 3 resistance ic both are replaced set ok 🤝🤝🤝👌👌🙏🙏🙏

Sir charger ki output section main 2 ic hai unka kya number hotahai bataiya

[Solder_it]

What is the input resistance in good circuit

[kumu]

Assalamu alaik, please I have a question. How would you be able to find a replacement for the IC:s you find damaged? Do you keep a stock of them or how do you do that? I would like to konw. Old boards might help but I am not sure if that is the case.

[MohsenSedighian]

Hi. Mr. Haseeb. I'm from Iran . I've a switching power supply that it's switching IC has been exploded. I would be glad if you can help me to find the number of this IC. Help me if you can . I've just two picture of it's board and i donot how should i send it to you . let me know the way.
best regards
m.sedighian.

Aslamualikum I sed this video when you conected the bourd to the lamp why the not go on

[vortexOGgg]

Sir I request you to please explain how each component of the battery management system works in ebike chargers. Regards .

[mohammadkhalid]

How do you discharge the capacitor, , , what is in a transparent white box, , , Jazakallahu khairah

arıza yapan diyotların yerine başka hangi numaralı diyotları kullanabiliriz. neden? farklı diyot kullanılırsa ne olur?

[yandrapuvenkatesh]

What is the number of damaed pwm ic and replace ic number. Tellme sir please
