The 10K preset associated with the above IC is set as per the battery voltage which needs to be charged. Does LM 338 have short circuit protection? Adjust the 10K preset under the LM338 such that the battery terminal points receive a 7V output. This automatic battery charger circuit is mainly involves two sections – power supply section and load comparison section.. Thanks Noble, you can try the last circuit from this article: Replace the relay with a 12V relay. ThanksRegardsKanta. This circuit is very simple and you also make this circuit easily. The following circuit will allow you to charge any battery right from 1.5V to 24V simply by setting up a given preset. next use this 10th pin of the IC for the cut-of function, do the above without connecting a battery, Sir why you have left the pin 9 of LM 3915 unconnected. pin9 decides whether to enable a bar graph mode of LED sequencing or a single LED mode…keeping it disconnected allows a single LED sequencing which we require for the above application, not the bar graph mode…. Automatic 12V Battery Charger is used to charge 12v Battery. Hi 'Mr Swagatam,I just finished constructed the charger using circuit no 2 with some minor adjustment and equiped with the temperature controlled fan using thermister (your circuit). sorry sir for my silly question , I got my answer while looking at the above comments . [2] "Now adjust the 10K preset under the IC LM3915 such that the last LED just flickers ON at this voltage, meaning at the applied 7V.". OK, I think the above circuit is in the "dot mode", please connect pin#9 with pin#3 (positive supply)…this will allow you to get a "bar graph mode" of LED sequence. This video clearly shows how can you make automatic cut-off 12v battery charger very very easy with 12v relay and BC 457 transistor. And it's not the SCR, it's working when testing out of the ciruit, and with a battery. Hi, please specify battery bank voltage, current, and solar panel voltage, current, I’ll try to help! Currently unavailable. thanks. your first point is possible, you can join all the 12V positives together and same for the ground line. I've noticed that when the RIGHT MOST LED (Connected to Pin10 of LM3915)goes on, the Cut Off Led also goes on. 94 $64.95 $64.95 12v Automatic Charger (Auto Cut OFF) then print it by any printer, and use any prototyping electronic circuit after that stick the paper to the board, Ask Question. 3) LM338 pot should be linear, and the preset should also be linear. With the charger in operation (power on), We will put the cut off switch in the position to cut the connection between base of BC 547 and the LED collector of BC 557. But, the series resistor (at the ground) for over current control is 0.167 ohm 6W (i connected 3 pieces of 0.5 ohm 2w by parallel) and this is very hot. I use PNP MJ5023 transistor. After referring to the diagram I should be able to provide you with my opinion. Since then, the output voltage of 7805 is 5 volt. This adjustment is done by the 10k preset , and a multimeter connected with the output terminals that goes to battery . Hi Nelio, whenever it's not specified it's always 1/4 watt by default , https://homemade-circuits.com/2015/09/how-to-identify-component-specs-in.html. LED connected at pin#10 is the last LED. English is not my language so please sorry for my bad English thakn you hop to hear from you soon. im daniel Ok sir thank you advice now i received your message.How to make a High Current 100 to 200 Amp Automatic Lead Acid Battery Charger Mr,Swagatam i like your good work you been doing so far i do like your project.my firs quotation is this 12v battery charger circuit i build it but when i power the the circuit relay switch correctly but the problem is out put is 11v and if i calibrate 10k preset to left side it switch on the relay and it give 11v out put if i calibrate to right side it switch off the relay and give me 13v out put why sir any help? Hi Nelio, yes you can use this design for charging a Ni-Mh battery also. I am planning to replace BC 547 with 2N2222 in order to avoid any mulfunction again in the future since 2N2222 have higher current of colllector emitter. The Jump Monster brand specializes in the development of automotive electronic products. When i checked the logo of the IC, i found the logo is different with the one i bought in singapore. But Cut Off LED remains off for all other setting. The panel must be rated at least at 18V. Wow thank u very much sir, u are great. The stage comprising the IC LM338 is a standard voltage regulator IC, the preset associated with IC is set as per the required full charge limit of the connected battery. Videos you watch may be added to the TV's watch history and influence TV recommendations. Actually, it's not a rechargeable circuit. Sir, I've made this circuit, It seems to me it is working, but there is a little confusion in auto cut feature. the best place to contact me is through the comments in my website, just as we are doing now. The transistor BC557 remains switched OFF as long as the last LED in the array which may be selected for the full charge indication is not illuminated. Mine is [email protected] !! Can i use this circuit to try on my project for the second time again ? Where should the middle of the 10k preset in adj pin of lm338 be connected. A 200Ah battery must be cut-off when charging current gets to 6A. 3 will the LM3915 monitor the battery voltage even when it is not charging? After the previous automatic battery charger circuit, I was not satisfied. By doing this, the charging process is started.4. BC557 base/emitter voltage will be 0 when the relevant pin of the IC3915 is not active (LED off)…if the relevant 3915 LEd is ON , only then the BC557 emitter/base would become 0.6V. I removed the battery, and the V meter showed 0 volt, it meant that the charger was off. Thank you sir , I am using 2.2 uf/ 25 v capacitor for that, as the battery is of 12V, I think it may work. the supply to this circuit could be given from the existing power supply, however the negative of the pin6/2 capacitor could be disconnected from negative and attached with the pin10 of the LM3915, this would enable the 555 to sound only when a negative appears at this pin which would in turn happen when the battery gets fully charged. i want to make 1W lED turn stay on.if AC available on AC, if no AC it shifted to DC battery and battery get charge but cut off when fully charge. [4] During the charging process each LED will correspond to 7/10 = 0.7 volts, meaning say at 5V the 7th LEd will be illuminated and with a rise of 0.7V the subsequent LED will be lit and the sequence will proceed from 7t to 8th to 9th and then finally to the 10th LEd shutting off the circuit and the charging of the battery. Hi Swagatam,Can I charge NiMh batteries with this charger? here's my email for better comunication, [email protected]. Is there any alternative . Hi chandrashekhar, you can use the second last concept from this article: https://www.homemade-circuits.com/usb-automatic-li-ion-battery-charger/, use 12V as the input instead of the shown 5V, and set the preset for the desired level cut off. This battery charger circuit provides the Automatic cut off the facility when the battery gets fully charged. Hi Swagtam, i want to charge my 3 lion battery connected in series with a 12 volt 2 amp charger. What do u say sir? Thanks, Thank u sir, i may understand u right, u meant the two output pins connected together to the base of BC557 one for desired full function(say pin 10 for 14.4v full charged ) and the other one for the restarting function(say pin 8 for 11.6 or 11.4). Ok so until here it works, But when i tried to adjust the pot under LM3915, then just one LED – the one who is connected to pin #1 of the IC, just flicked and nothing else happened. In this project, I will be going to show you a 12V automatic battery charger with auto cut off when the battery level is below the maximum threshold voltage. hi sir i am building this circuit named Making a 3KVA Modified Sine Wave Inverter Circuit please my questions is, in the circuit there is 50nf and 5nf so can i use 104 cap to replace 50nf and 0.01uf to replace 5nf,sir there is something that i don't understand, is that circuit a pure sine wave or modified sine wave cos im confused if you look at the top side its named modified wave and you scroll to the down it named pure sine wave which is which sir? A bypass diode 1N4007 is connected from emitter to collector (cathode to emitter)10. Hi Solomon, the ideal charging rate for any lead acid battery is 1/10th of its Ah level, but this not entirely critical, if you are using 6.5Ah that’s only marginally more, so no problem you can go ahead with 6.5Ah and still charge your battery safely. Hi, the image that you have uploaded is the same which is presented in the above article, just click on the article diagram to enlarge it and get a clear view of it….your upload is very dark and unclear. I have inverter circuit, automatic cooling fan circuit, mains AC overload protection circuit, all operating with 12v voltage source(battery), is possible to join all their positive terminals on one place and all their grounds on one place on my circuit? are you using a breadboard?? Auto Cut Off Battery Charger (12v or 24v Automatic battery charger) - EasyEDA. In your circuit, whether it is the LED(Connected to Pin-1 in LM3915) which is at the LEFT MOST, or the RIGHT MOST LED(Connected to Pin-10 in LM3915)? Siri want to make a light, with rechargeable battery, battery charging keep plug in with over charging breaker. Pls help sir, thanks. Hi Kanta, can you show me the schematic which you are using? Can you tell me how to make the base/emitter voltage of BC 557 become at least 0.7 V. The Power to supplies the LM 3915 is using 7805 since the beginning. Hello Goran, you can increase the base voltage of the BC547 by replacing the 3v zener with a 6V zener diode. i am having littlebit knowledge of electronics. i have 4 "3.7 v, 2200mah" rechargeable cell which is connected parallel. I now removed the cut of transistor in the adjust inputs of my two LM338, and replaced this control performed by an Op amp. 12 Volt 1.5 Amp Battery Charger with auto cut off overcharge protection, UPS battery charger. The main component of this auto battery charger circuit is a 555 timer which compares the voltage in the battery. Yes you can salvage most of the passive parts except the ICs. This is for the cut-off setting. I could not find the datasheet of MJ5023 so I am not able to verify its minimum base/emitter saturating voltage of it, 2.2V seems to be high, I don't think that may be correct. Hi i had a catamaran very old is a project it have 2 dc motors 144 volts and a battery bank it suppose to work with solar panels an a gas generator and i would like to had a battery charger for that voltage changing some values on this thanks my e mail is yudando [email protected] thank2. A 1K/0.25W resistor is put in between the Base and the junction of the 1K/2W resistor and V-in pin of LM317.5. Pls correct me if wrong. Here are 4 circuit ideas. yes that will also do! Can you please give me one more advice…The LEDs are working when replaced 10K with 1K, but the base of BC547 receives 2.3V, so the emiter provides not the fixed 3V but 1.7V, thus when the "last" LED lit up, and the BC557 network is closed, the collector of BC557 provides also just 1.7V, which is not enough to lit up the cut-off LED, so that can not trigger the gate of SCR, because there is just 0.05V, and so the ADJ can not grounds and disable the output.What can i do in this case…? 1. The ideal transformer would be a 12V 10 amps which will become 16V 10 amp after rectification. I.e (7.3 + 6.4 )/2 = 6.85 which is about 6.9V. The IC spoiled. I am afraid that should not happen, with pin9 connected to the positive supply should produce a sequentially increasing or decreasing bar graph type illumination on the LEDs in response to a varying voltage at pin5….this can be confirmed by adjusting the pin5 preset…, just move the 10k preset clock/anticlockwise at pin#5 and check whether this happens or not…. And what should be the preset voltage for that type of accumulator (10.2 will be suitable, but won’t charge it completely?) Hi sir This is Fahad. Automatic OFF 12V Battery Charger by power SCR. You can take the help of an online "555 calculator" for getting the exact part values. 10k is for biasing the BC547 base, so that a 2.6V can be achieved at its collector for the LeDs. One 10 positions selector to match the base pin of BC 557 with the relevant LED pin of LM 3915 for the full charged cut-off.2. The setting of the circuit may be done in the following manner: Alternatively if you you are interested in making the circuit respond with all batteries from 3V to 12V then you may adjust the LM3915 preset such that the last LED barely illuminates at 14.4V. It will be appropriate for Ni-Mh accumulators, which charge at constant current? yes you can use it, but first confirm the set up with a normal power supply. Still talking about the last diagram sir, now it means the BC547 near the voltage regulator serve as the cutoff region to replace the scr? You really are a genius . you can replace the entire BC547 stage with a 7805 IC to make things simpler. Thanks Mr.Kant for your untiring efforts and determination, congrats to you. So, the circuit in this article monitors the charging of the battery and takes the input from the charger or bridge rectifier and charges the battery, when the battery voltage reaches the certain level it cuts off the charger and stops the battery … 1) can i use this power supply as a battery charger to charge 12volt 100ah battery 2) what circuit is required additinally. Automatic 12v Battery Charger Circuit | Auto Cut OFF & ON. sir i need a solar charger for 12v battery with driver circuit for led lights. It was normally operated, but after about about 3 minutes charging, the volt meter showed 6.4 and the current was 0. Can i just prototype it using breadboard also ? This is the second time the IC damage. Adjust the 10K preset under the LM338 such that the battery terminal points receive a 7V output.". The LED of LM 3915 is in the bar mode. If you want to charge a single battery with fixed voltage then I wouldn’t recommend this complicated circuit, there are much easier circuit present in this website. Hi Muhammad, even a single of these cells cannot be charged using a cell phone charger at normal speed because each of the cells will require an optimal rate of 2 amps, that means together all the 4 would require around 8 amp current. If playback doesn't begin shortly, try restarting your device. Se my new diagram (with a fan speed controller (LM358) to a fan mounted at LM338 cool radiator ribs)): https://drive.google.com/file/d/1BcWFbQ4H9nvMQs__i-Ixc0oCYdoVJD96/view?usp=sharing. I am thinking it might be the 0.6v is not enough to activate BC557 since it requires minimum 0.7 V base/emitter. My question is what kind of circuit would I need to add to place a solar panel to keep the battery charged properly.Thank you sir, you can use a 15V panel and connect it directly with the battery terminals…the current of the panel can be around 7 to 8 times less than the battery AH rating, Hi sir,I didn't find that schematic.its showing error that "no posts available for your search", https://homemade-circuits.com/2015/08/lipo-battery-balance-charger-circuit.html, Hi Anu, please find it using the search box on top…..It is already posted in this website, Hi sir,please help me to built a schematic for lithium polymer charging and protection circuit with voltage 3.7v and charging current 65mAh. Which LED do you mean by "last LED"?? I remember last time when i charged the 6V battery, the led light was come and gone and the current to battery was still flown at 0.03 to 0.04Amp when the cut off voltage of 6.9 achieved. THANK YOU SIR, YOU ARE GOD. it was meant for a different application and suggested to a specific user, the existing diagram is the final and correct one and should be followed as given. Hello Mihai, I think your battery full charge level is 8.4V, and the printed value is 7.4V (3.7 + 3.7 = 7.4)….So make sure your battery does not charge over 8.4V, otherwise it can get damaged. I found the link u have provided is quite effective for me. this might be caused by the damaged LM338 (non genuine IC) in the past.

To get 10 amp output you can connect two LM338 pins in parallel with a common regulator circuit, and also make sure to mount the two ICs over a common heatsink so that they can share the dissipation uniformly. Hence, (8 + 6.9)/2 = 7.45 cut off in order to get final charged battery of 6.9V. Watch later. Can i use this circuit to charge a 12v 200ah battery or should i make some mods, No it won’t be possible, unless you upgrade the LM338 with an outboard transistor so that it is able to handle upto 20 amps, Hello sir, i used lm317 instead of lm338, 1. if i want to add transistor 5A to it, in order to increase the current, will affect the 120 ohm resistor, or do i hav to change the value. I meant as inverter having battery input wires, red and black out from the inverter’s frame, if now i want to charge the battery of the inverter, i must connect the battery through external charger. Check the voltage at the preset slider pin, while adjusting the preset as this voltage rises the sequence should shift from pin#1 LED towards pin#10 LEd and vice versa. so at 14.3V adjust the LM3915 so that all LEDs illuminate and the 10th LED just lights up (touch and go). The schematic given in the article is more correct, so you can build as per this diagram. I’m from Romania and i’m glad to have had the privillege to benefit from your experience of electronic engineer and to meet you, even in this manner, by comunicating through the internet. i want to ask alittle you said that if one wants to charge batts above 50Ah he should think of adding a transistor say TIP. Thanks olupot, actually that will not show a numerical display, rather only a digital bar graph display, I have shown LEDs in the above circuit because LEDs are easier to procure and connect. please specify in detail. if the pipe within the wall is made of steel or iron then it could be identified using a metal detector circuit…but if it's of plastic or PVC then it could be difficult to locate, Hi Mr Swagatam,This afternoon, when i charged 6V 4.5AH battery, with 7.3Voutput from the charger, i put 6.9 cut off. The IC has ten linearly incrementing output which sequence one after the other in response to a rising potential fed at its pin#5. yes the LM31915 will continue to monitor since it is directly connected with the battery supply, you can use any SCR, but BT151 is rated at over 1 amp which is not required, it just needs to be 100mA, hello sir i have got a tip142 rated at 100v collector current current ic 10amp. instead you can do it over a PCB by soldering for better results. I'm looking to integrate it into an old SEGA Game Gear so that when plugged in, it charges its 6 rechargable AA batteries. This High current charger can be used for the Fast charging of sealed lead acid batteries used in Automobiles, Inverters etc. But sir can i use 4.7 mf instead of 2.2 mf . now wil i need to add a resistor. BC557 base will be always have 0.6/0.7V and this value can never increase, if you try then the transistor will get damaged. you can try charging each cell individually using a 4.5V 2 amp transformer or smps adapter. Part 2: DIY Universal Battery Charger Circuit with Variable Auto Cut-off. Info. What is the model of zener, that you use?I used BZX85C 3V0 -> with this one and 10K the LEDs are "dead";with BZX55C 3V0 and 10K, the LED's are lighting even very strong, and 547 is burning out, after getting hot for a short time; with more than 3.6V zener i have to increase base resistor of 547, otherwise, 547 is burning out. . Thank you. For a 24V battery the 5th LED will correspond to 14 V, but the indication range will keep getting squeezed more and more as the battery source voltage increases. In my vehicle I have provided 12 volt 30 amp cable (8mm2), to place the wheelchair is located. It is the circuit to charge battery by getting a DC power input to the circuit and output goes to different batteries to charge. The input in the diagram states the input should be 28V, the plug on the Game Gear is 10V, will 10V suffice for charging the 6 AAs (9V)? since each pinout for a 12V battery would correspond to 1.2V, two of them would enable 2.4V difference, so last two pins will mean the battery getting cut off at 14V, and restarting at 14 – 2.4 = 11.6V. these can be very clumsy and very difficult to troubleshoot. ground indicates the common negative supply line, yes it should be connected to the negative point of the bridge rectifier. The input can be upto 32V without any change in the circuit, only the LM338 pot needs to be adjusted for setting up the correct charging voltage to the battery. That is why the cut off led last time was dim come and gone hardly seen and cut off was not happening. Here I should connect BASE to BC557 / PNP to LED furthest to the RIGHT, when output voltage is regulated under LM338 to around 27.5 volts? The BC557 collector LED must light up, otherwise your circuit could be assumed to be not working. yes it can be used with an inverter, the shown IC338 is specified to handle upto 50 AH battery. I am really sorry Aditya, personal contact may not be possible, I can solve your queries only through this platform! 3) the counting of LEDs is starting (the first LED) from those, connected to the pinout #1 of IC, and the 10th LED is those, connected to the pinout #10 of IC. Hopefully by doing this all transistors will be functioning properly. The 28V must be a DC, it may be from any kind of source. 2) It is 2.2uF but it can be any value, it is not too critical. Your email address will not be published. It is quite OK, even though the led no 10 cant glow with low voltage. t&R Prashant, Thanks Prashant, you can use a buck conveter to convert 24V 2 amp to 14V/ 3.5 amps, but this current can be too low to charge a 100 Ah battery, as it will need minimum 8 to 10 amps for optimal charging within 12 hours, hi, thanks for your reply, it is possible with this ps obtain higher current? Automatic 12v Battery Charger Circuit Diagram Circuit Diagram of Automatic Battery Charger. It can be used for all types of batteries but with appropriate current control setting. we would be pleased to have your correspondance details. Thank you! This video clearly shows how can you make automatic cut-off 12v battery charger very very easy with 12v relay and BC 457 transistor. If you want the above multipurpose battery charger circuit to cut off the charger while the battery reaches the full change limit, and then quickly switch ON the charging when the battery starts dropping below the full charge limit, and continue flip flopping at this threshold level, in that case you can try modifying the design in the following manner: You can try increasing its wattage to control the heating. Hi Swagatam,Thanks for your kind support.

A bypass 10uF/50V tantalum capacitor is connected from ADJ pin of LM317 to ground.12. This is to limit the current going to LM317 before the transistor turning on. I don’t really know if the schematic you recomanded me is better, and if so, please explain me why. Here is a 12 volt lead acid automatic battery charger that shut off the charging process once the battery attains full charge. Hi Swagatam,It is me again. & auto charging? For this you may incorporate the following design: 1.bp.blogspot.com/-I2zlapFq6RM/UML_NxUJy2I/AAAAAAAAB3w/27ZLDjK9C9g/s1600/simple%20modem%20UPS%20circuit.png. The moment i attached the battery to the charger, the IC gone. And also…i bridged collector of 557 (there is 1.7V when it's closed) with the gate without LED and resistor, but when 557 is closed, these 1.7V drops to 0.4V so the gate can not close. A 1 watt LED will burn if you do not mount it over a heatsink, and also preferably add a resistor in series with its lead, for 4V input you could add a 2 ohm 1 watt resistor. _/_I'll try this at home at night. Then, we will turn the potentiometer of the adj pin of LM317 to set the cut-off voltage (ie. i try to charge it with 5v nokia charger. If i connect the input of the regulator to the collector of the transistor, the output to the base, then the emmiter should now be the output, so my question is, from ur diagram, should i disconect the end pin of 120 ohm resistor and the diode anode at the output of the regulator, and reconnect them back to the emmiter (the new output) of the transistor? More precisely you can add one more LED right across the OUT pin of LM338 IC and ground. And now, the cut off led does not lit at all.ThanksRegardsKanta. I'll try to update the finalized design soon, may be tomorrow…..please stay tuned. Hi Kanta, a good LM338 will have a clean and thick steel body with thick leads and a clear etched print which cannot be wiped off easily, these are the general external indications….as per my experience ST make ICs are mostly good. you can use any 555 astable circuit at a frequency that would create a buzzing sound at its pin3, with a small speaker connected to ground. One cut-off switch between the base of BC 547 and LED collector of BC 557. if no, i need modification pls. you will need resistors as per the explanation provided in my previously referred link. Just before the IC or other place you have figured? One potentiometer on the pin no 5 of LM 3915 is for setting the LED lighting for full charged cut-off. I have 6 solar panels each 200W and 38v, and 2 batteries each 12v and 200 ah, now can I use the above circuit in 24v and for up to 50 amps?Second I made 24 inverter local made from transistors 2N3055, with the mentioned systems the ceiling fans, washing machines and other motors are making noise even I used 50v AC capacitor in output AC side but still the same, could you please help me? You must watch the artificial. The circuit can be used for charging 1.5V, 3V, 6V, 9V, 12V, 15V, 18V, 21V and 24V batteries, in fact any voltage that may lie between 1 and 24V.
