{844} 48V Ebike Battery Charger Repair

[@jaym5938]

Awesome! Thanks! Question: how did you test the switching signal? You used a meter in what mode? Thank you!

[@bobsoft]

Frequency

[@jaym5938]

@@bobsoft Is it Hz%? I have the same/similar meter he's using but he switched meters. I'll try to review the video once my Internet connection is restored. Can't see enough on my phone lol. Thanks!

[@bobsoft]

@@jaym5938 Yes frequency is measured in Hz

[@HaseebElectronics]

best regards i used Uni-T 202A+ for frequency measurement, it have separate frequency and duty cycle function button, and its frequency reading is awesome i measured the reboot frequency around 20KHz,

[@HaseebElectronics]

@Jay M it is around 20Khz frequency

Hvala vam Haseeb na razumljivim objašnjenjima, zahvaljujuči kojima i mi, koji nismo stručni ali volimo elektroniku, možemo da shvatimo suštinu problema. Pohvale za vaš trud, i znanje koje nesebično delite !

[@HaseebElectronics]

srdačan pozdrav i posebna hvala na vašem vrijednom komentaru. Budi blagoslovljen

[@trevorjames5493]

Very good video and easy to understand right to the point. you would make a great teacher and your multimeter is awesome. but I must say the most impressive part of the video was in the beginning when you opened the retaining clips with your fist somehow. I always fight with those to open and usually damage the case with a screwdriver doing so thank you and cheers from canada

[@German_byte]

Another excellent video. I think the customer would be very happy. In many countries the user would just throw the charger away and buy a new one.

Trouble shooting is difficult this time. I had a good look though. I want to do well too! Thanks for the video as always.

[@HaseebElectronics]

yes you are right, it is difficult to troubleshoot, but if we understand the circuit and we work logically, then it becomes like a piece of cake wish you best of luck and success in every field of life

I have a similar charger. I opened it to modify the voltage using the tl431 divider circuit. I found the tl431 but could not find the voltage divider resistors. Never encountered such a design.

Can that diode and resistor be replaced with normal diode and resistors..I mean other types

[@HaseebElectronics]

if we cannot find smd components, we can replace same value normal resistors

Great video, what if we dont have any voltage to the secondary side, mosfet is good it has voltage, but voltage is not pasing to the secondary side, fuse is good, bridge req is good...

[@Steve_be]

Can you go through a PFC LLC PSU like used in playstations

[@Todestelzer]

I would recommend to use an isolation transformer when dealing with smps.

explanation is good sir by same method i repaired same charger it's turned on. output voltage ok but ampere decreased 3ah to 700 ma # opto coupler good # used various mosfets # changed upto 3qty 3842 ic also # TL431 also good ok # all capositors are 100% accurately tested with capositance meter is any differents in mosfets? please give some suggetions...sir

[@HaseebElectronics]

please check its RCD snubber circuit check current sense resistor (connected at source pin of the mosfet) check output side LM358 or any operational amplifier IC for battery management

[@poornaelectronics5952]

@@HaseebElectronics RCD snubber circuit is good with fr154 diode current sence resister with 810 ohms is good and the outpu side BM lm358 icc section is designed by chip module with small components battery charging, full off led's sections also good this is the critical problem sir i never seen yet is any chance to fail DT transformer

[@MUHAMMADYOUNUS-j6l]

Where from we get 16 volt voltage

[@HaseebElectronics]

initially vcc voltage are obtained from startup resistor and after startup it is from bias winding or auxiliary winding or vcc winding

When I plug my drill charger, light turns on but turns back off and it remain off. Charger doesn't work. Why does the light turns on and turns back off when I plug it in? Where could the problem be? Can this be fix?

[@HaseebElectronics]

it means its smps converter section is good. it have problem in battery management system. so you need to check the output points and its related circuit. that it is interrupting the charging control circuit
