Auto cut-off 12v battery charger
Вставка
- Опубліковано 27 гру 2018
- Hello friends, in today's video i have shown how to make a simple automatic battery charger circuit with auto cut-off facility. You can use it for any battery. You have to just set the threshold voltage as per your battery.
Normally the relay is OFF and battery charged but when battery voltage increases to the selected voltage the relay energized by the transistor which now disconnect the battery from the charger thus it prevents from over charging.
Parts list:-
12V relay
BC547 or any transistor
1K resistor
3.3K resistor
Red led (To indicate charge complete)
Green led (To indicate charging)
10K preset
4 diode
1000 uf capacitor
1 Step-down transformer as per your battery voltage

Thank you very much. - Наука та технологія
Это хорошо. Идеи простые и работают. В некоторых случаях - это то, что нужно.
Good job my good friend, thanks for sharing 💯👌🏾
Thank you for the video. I will built this charger. I wish you'd show the schematic as I'd do more of your projects if you did.

Hello, what needs to be updated in your circuit, if I want use it for batteries in series (300mA with 195VDC in total)?
It's really working,but for nice working the 3.3k resistance have to change (reduce),and adjust the preset very carefully,Otherwise the circuit will not work.
Excelente. Muito bom!
It nice my freand .thanks 4 u.
Does the relay chatter when the voltage is around the cut-off threshold?
I want this to work with a 24 V transformer.
Is it enough to do the assembly with a 24V relay?
Hello thanks for your video. And could you please tell me how many volt you use to set the level in to 14.2 cutoff range?
Thank you so much, this is what i was looking for to install in my motorcycle for the anti theft alarm system(i just changed the 9 volt battery with this), everything is working properly except one thing, when i cut off the input (which might happen if the motorcycle battery go down) the relay start giving a laod buzzz sound, i need help please.
Muito bom viu um carregador inteligente
Before connecting the out put to the battery the red indicator was on when you switch on power,but immediately you connect the battery green led was on. please could you explain why this happens?
2.19 BC 547 Transistor. Obrigado amigo. Muito bom mesmo. Brasil
Wagner Olino what c815?
очень полезная вещь, спасибо обязательно реализую в жизнь!!!!
===регулятор подачи напряжения на аккумулятор с отсечкой И ИНДИКАЦИЕЙ !!! СУПЕР ===
МОЖНО И 13 И 14.5 ВЫСТАВИТЬ Я ТАК ПОЛАГАЮ !!!!!!!
hola amigo buena explicacion. una pregunta yo tengo un rele de 4 pines se hace igual la coneccion, porfavor si pudiera decirme,, saludos
Please Sir red led lights up when I connect output to the battery indicating no charge
Sir kya 12 volt adaptor ka voltage extended kar sakte hai
what did you use to supply the 14V?
Light or fan ko auto charging system se joda ja sakta ha kya? Light jana par apne ap continue rah sake
Very Nice presentation....!
great video! the best so far!
What is the approximate loading time, please?
Very good project. See from Bangladesh.
Thank you bro
Saim diagram will work with 48v leadacid battery if we change put 48v relay and 48v charger ?
otimo projeto parabens
3 volt 6 volt battery charge karna uske liye autocut konsa Sahi Padega
Bonjour monsieur. dans plusieurs vidéos, j'ai vu qu'on ne mettait pas toujours la même valeur de la résistance qui va du relais à la résistance variable. Dans votre vidéo, vous mettez une résistance de 3,3 Kilos ohms et dans dans les autres vidéos, ils mettent 15 kilos ohms ou voire 10 kilos ohms pour la même valeur de la résistance variable. Est ce que la valeur de cette fameuse résistance a une importance? Merci de me répondre.
I did the same as shown in your video but it is not disconnecting my supply even after the battery is fully charging,, am I missing anything?
Posso usar um transformador 16v
Good evening sir. Itna achha circuit banaane k liye bahot bahot dhanywad. Battery kitna discharge hole pr again charge hole lagega means battery ka voltage kitna rhega toh transister conduct karna (off) band kar dega
Please tell any one preset jo set krna hy wo output pe set krna hyna..?
Thanks a lot.. other videos did not show how to set up the trimpot but you show it in details. Ultimately i can made the circuit. Thanks a lot again. I also subscribe your channel.
Thank you very much
Don't always put background song in video. Try to explain everything what you do.
and the music is unbearable !
Hahahaha I agree with you bro
Agree ..
Watch my videos channel name anklabs
Soon I will upload a content on this topic
Agree my friend 👍
Do you know what is the problem with these people, they think we know everything what there doing
Can iuse 2amp transformer to charge 6v battery
Can I use it for three wheeler battery? As a rectifier?
Very good. Really enjoyed. Grade 10
A good experiment. Congratulations ! It miss electronic diagram.
This is crystal clear
I want this circuit for 54 or 48 volt battery. What is changes for the that? Pls suggest
a better way to do this would be to build an op amp comparator with hysteresis. That way you can trigger the charger to charge the battery once it drops to a certain voltage
Please Sir could you use it to charge 3.7v lithium ion battery.
Well done nicely presented and put together. Thumbs up all the way. But next time first show the circuit diagram for the youngsters to make them see what they have to do. Thank you. Keep it up
Thanks
You should add bc 547 transistor in your list. The transformer can be above 12 v to 24 v
i am thinking about this thank you
If we don't have bc547 transistor than we can use bc548
@@ajaypandit7381 yes
Use it for 12v 30amp battery ...?
Nice thx u what type of resistors metal. Film , etc.......just any 1k
great idea, thanks
all ingenious is simple.
if the battery is plugged in when it has 50% charge will this still stop the battery from charging when it hits 100% or will it keep going until enough power has gone to the battery to charge the battery from 0% to 100%? if u could let me know id really appreciate it
Can we use this for 9v batteries?
This is a very nice solutions and it's exactly what i was looking for. I also shared in my facebook automation electronics group. Thank you !
Nice
Sir kya hum isko 6v ki battery charge bi kar sakte hai
Yes, everything is fine and just like two fingers on the asphalt.
of the 4 diodes of what size
GREQT,GREAT,GREAT.... but where's the schematics??
Can you drop it??
Thanks in advance,...supporting!!
What is the use of 4 diodes and 1000uf capacitor?
Bro Can I use a 12V adapter in the place of Transformer?
Sir ye 150watt solar panel p work karega
Nice i will must try
What is the use of "preset" in this circuit
Excellent!
What diodes did you use?
How many volts and amps ?
I would guess only like 5 Amps
very much muy bueno, me gusta
Please reply

good afthernoon sir it can charge lithuim batteries ?
@@cwe-mbe7768 sir no it's not charge the
Bro mujhe btoau ke 5 volt reley circuit kitna zyada volt tak cut kar Sakta hai or kitne Kam tak please
Great project but picture of the schematic will help diyers better understand the concept . recommended to install a safety reverse diode across the relay coil to prevent recoil hi voltage from damaging parts ..
Which relay is required for shut off mobile charger?
Divert konsa Lena hai
which transistor u used??
Thanks a lot
que transistor se uso no veo el numero .npn o pnp
When you adjust to 14 volt. How do you connect the wire.. and from which power source the 14 Volt comes. Its not appear in your video...
12 volt transformer will give 14v because bridge rectifier makes the transformer voltage 1.21 times.. it's the property of bridge rectifier
Excelente cargador de batería.
Dice que puedo usar cualquier transistor?
Muito bom
when the battery stop charging the transistor generate heat to much
Cool, but too delicate. Just need a board to fasten too. But thanks for the educational vid
please sir for the circuit diagram i really love this project i want to build mine now
thanks waiting to hear from you
Preset ke jagha koi aur chiz jod nhi sakte kya
Sangat bermanmaat...
AMIGO ESTA EXCELENTE PERO QUE TRANSISTOR ES NO PUSISTE EL NOMBRE O ACASO ES BC548 O BC547
Sir ji apne diode kitna no ka liya plz comment
Show 👏👏👏👍👍
Congratulations to you sir . sir please one question.. witch is the foods number or value..
I have replicated this circuit and still no luck. I get the red LED on for battery charging but no matter what resistance I set on the variable resistor I can not get the relay to switch from NC to NO. PLEASE HELP, I AM GOING CRAZY trying to make this work.
Thank you and many blessings!
is posible use an transistor 2n2222?
Sir plz reply
If I want to increase the battery size , suppose I want to make 10 Amp battery charger, then what are the item I have to modified from your circuit.
1st replace power supply transformer
also replace transistor, bc547 can handle only upto 3A current use a bigger power amplifier type 2n3055 or 2sc5200 transistor for 10A Transformer Circuit
