{1133} Ebike / Electric Bike Battery Charger Repair

[@shyamsuresh1723]

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

[@shyamsuresh1723]

I know you are doing this for test and educational purposes and you are way more experienced than i am. You probably already know what i mean but i just wanted to point that out

[@HaseebElectronics]

yes. i agree with you that is great suggestion.

[@antiamperak]

​@@shyamsuresh1723Naprostý souhlas je i dokázáno že i poslední dioda je poškozena, tento stav je velmi častý dochází k poškození PN přechodu a dioda v závěrném směru ztrácí odolnost proti průrazu. Proč to teď dioda vydržela je jednoduchá odpověď zdroj byl nezatížený a navíc byl připojen přes omezení proudu ( žárovka)

[@pericacvijetinovic1810]

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

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

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

[@AKCOMPUTERS]

IC MOSFET NA MILE TO KYA MODULE SE READY KIYA JA SAKTA HAI SIR JI ?

[@antiamperak]

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

[@Solder_it]

Very good video prof and thanks for sharing, i have one question, how can i know if that sound is normal or not? Humming sound

[@remediusfernandes1570]

Thanku sir🙏

[@mehranmohamad6924]

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?

[@HaseebElectronics]

almost all gate drives are protected by a simple fast switching signal diode like 1N4148. so that the PWM controller ic will not be effected by negative transients generated by mosfet switching and gate discharging

[@thebloody_blue]

the capacitor is at zero volt, How that is an indication for bad IC? can you pleas explain. is it a filter cap for powering ic, which is comming from the main power line.

[@sandeepmane2983]

1 Number work 👌

[@vortexOGgg]

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

[@German_byte]

Brilliant work

[@rajkhumar001]

Awesome sir🎉

[@thehooplabs]

Excellent sharing....

[@kumu2024]

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.

[@SanelKeys]

Search on google for datasheet and/or replacement or equivalent IC.

[@GagjeetSingh-s1y]

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

[@palwindersandhu2031]

Thanks very much dear .....

[@mohammadkhalid6886]

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

[@German_byte]

Watch video number 1114 to see how our teacher discharges capacitor.

What is the input resistance in good circuit

[@ztechno6316]

Aoa sir. Please guide 67v ko 73v kesy karin

[@MrDricooh]

Where to buy that soldering

[@fuppup]

Thx a lot🤝

[@ComputerExpert1]

Thanks for sharing Sir

[@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.

[@rahmatullahpopal9347]

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

[@HaseebElectronics]

if the smoothing capacitor is already charged or it is small in capacitance size, the lamp will not glow. actually the circuit draws current but that current is very low that, it cannot illuminate the lamp

You're welcome!

Thanks ..

[@iosifferencz5432]

Acolo cauza este "greseala proiectare" poate si intenționata pentru ca sa mai cumperi si producat +lant comecianti sa aibe de lucru.. la fel si Dvsțra . Sunt solutii ca un produs sa tina multi ani dar ne mai exista interes😢.
