I tested some projects to make my UPS. With MOSFET, with relay, etc. And as always I had some kind of problem. I did some tests with the XL4015 used in this project and arrived at the following solution that I'm still testing, but so far no problems. The power source connected directly to the input of the XL4015 (for battery charging) and a step up/down connected in parallel with the XL4015 (to regulate the voltage that goes to the router). The battery is connected to the output of the XL4015. In the tests that I did the behavior is the following: On the XL4015 you can control voltage and current from IN to OUT. But in the opposite direction, OUT to IN the supplied voltage is the same as the battery and has no current limit. So while the power supply is on, it charges the battery and provides power for the Step Up/Down. When the power supply is turned off, the energy passes from OUT to IN, providing energy for step Up/Down without router restarting. So far everything working OK, inside the case (without opening for air circulation) the temperature is approximately 30ºC. uploaddeimagens.com.br/imagens/gtpRh_I

Thank you for the feedback. This circuit is really simple, I will definitely gonna try it soon. If you have any further test results, please share it.

@walberjunior Год назад

@@opengreenenergy I'm planning to put more load on the circuit this week. My goal is to connect 1 12v 2a modem, 1 12v 2a router and 1 rpi4. At least in the tests I did, the modem does not consume more than 0.500a, despite the specification of 2a on the label. But I'm going to test with other devices first so I don't risk running out of Internet and without rpi4.

@roshan00778 Год назад

@@walberjunior hey, whats the ratings of your input adapter and are the batteries getting charges fully as li-ion battery require cc or cv method for charging? what voltage & current have you set in both the convertors for your router? do i need to buy a smps as the whole 2.5amps(my router rating) which comes from the input will be used by the router itself?

@walberjunior Год назад

@@roshan00778 I changed the project to power 2 routers, 1 rpi4 and 1 esp8266 to integrate with Home Assistant. Until today working very well. The rating if I'm not mistaken is 5A, but it's a Chinese product so it probably doesn't deliver 5A. Batteries are fully charged. The charger I configured for 16.8v@500ma. The converter that feeds the routers if I'm not mistaken is in 12.1V. It depends on your project, how many batteries you are going to use, if you need faster charging, etc. If you can measure the actual consumption of your router that would be great. One of mine uses a 2A power supply, but the actual consumption is no more than 800/700ma. Most products do not deliver what is on the label, but the minimum you need is a 2.5A power source plus charging current, let's say you use 500ma, that is at least 3A real.

Thanks for a great video.. This helped me a lot to make one myself. MOSFET idea was great for switching.. I had an issue to find the correct case since 3d printing is costly but found a plastic junction box from electric shop. Soldering worked for spot welder and MOSFET heating was an issue which was mainly due to oversite on diode usage which looped the power back from battery to gate. Thanks again..

@SazzadHossain-ww3xo 2 года назад

Hi, thanks for sharing a nice & useful project with us. But I think in your design two thing u don’t design it carefully 1. 12v Output whens the the mains powers is active: u set input voltage 13 volt and its directly connected to output by a diode. If the foreword voltage drop is .3v the output voltage will be 12.7 v which is high for the 12v output. 2. power switching : whens the mains on 12v output jack provide 12.7 . Now power goes and battery pack start as u set buck boost converter output 12 v. Thats mean when power switches there always a 0.7v voltage spike it’s not god for router. Suggestion: 1. u can connect input 13v main power supply in input of buck boost converter not to output thus u get always a steady output voltage . 2. U can use electrolytic capacitor in input & output dc port to reduce ripple and get steady voltage.

@opengreenenergy 2 года назад

Thank you for the most valuable feedback. I was also thought to connect the adapter output at the input of the buck boost converter but changed my mind for considering the continuous power wastage in the converter module. But I missed the point that I am not using a 12V adapter at the input. Use of capacitor is nice feedback. I will update all these in my schematic soon.

I simply modified my APC offline UPS by replacing the 7AH battery with 2x20AH VRLA batteries and added a small fan to the internals that get hot when the UPS takes over, the 110v to 12 transformation loss is so little and can be disregarded. My cable modem can easy run 24 hours and even longer when power fails, my TV is also connected to it and digital TV decoder so with all powered on i have around 3 hours. Usually power outages don't take longer then 2 hours in my area and are mostly the result of a blown transformer or maintenance at the hydro powerplant turbines.

1:39 mosfet used is P type as it connected on high side. It seems correct. But R2 is connected to groud. Shouldn't it be connected to positive of battery? So that gate of mosfet is pulled high when battery is not suppose to supply power and hence the mosfet to be remain off. When main adopter power cuts, gate should be pulled low (so in a way it is correct to connect gate to positive line of input buck converter but it should be connected through some resistor or a combination of BJT and resistor). Now another problem i feel is that when the battery is significantly discharged and main power gets on, circuit may not work as desired. Just were my thoughts. Any expert comments?

@electronicslab_in 2 года назад

Another way could hv been using a N channel mosfet but connecting in negative rail (but at same position) and controlling the gate using positive bus of input supply.

Does the backup power kick in as soon as the DC from the mains drops? This inverter also doubles as a power supply in itself.

@bwraith 2 года назад

Based on the design, the power is flowing always from the batteries, if the mains drops the batteries will remain active. Mains drop only prevents the batteries from charging, the BMS is what handles the majority of this on it's own as well as maintaining the batteries at a constant state of charge while plugged in,

You can use any diode with current carrying capacity more than 3A. Try to get Schottky diode ( SR560) , if you will not get, you can buy any general purpose diode.

Hi, awesome project: a question, if i don't need 5/9v output i can just avoid to add the 2nd XL4015? , thanks!

@opengreenenergy Год назад

Yes, you can omit

A couple of things based upon my experience of building this router, first and foremost i am hobbyist it was super easy to follow your instructions and build it. 1. Around mosfet would be great if you can showcase which point gets to connected to where itll be easier i got stuck there and it took a lot of time. 2. Around input power i tried using the default adaptor of my wifi but thats only 12v and its unable to charge batteries beyond 11.4v and its heating a lot. 3. If ill use a 14v supply for input wouldnt it fry my wifi as the power from supply will be connected directly to output

Where you plug mosfet?

Bro did you get any trick to charge battery beyond 11.5v even I am also face the same problem 😢

Hi. What is the power supply voltage for input? I read 12V-15V, but working with a 12V? The BMS need 12.6V. Thanks for your support!

@kenanelicanov2327 10 месяцев назад

It is also interesting forme. I think the converter at input will be boos converter to boost 12v to 12.6 v from router adaptor

@Ultimateharen 10 месяцев назад

@@kenanelicanov2327battery will take too much time to charge too inefficient. Battery will get damaged after few months. Instead of that use 13v or 14v 15v adapter.

Which type of filament you're using to make the enclosure?

I like what you have done here, I want to build one myself, but I need to have "24V 15A input" and want to use 2X 12v 9Ah Lead Acid batterys as the battery pack, need 2X 20V 4.5A outputs, 2X 12v, and 1 to 2 5v 2A outputs and maybe others, I don't quite understand how the charging Circuit works or how to set it up for this type of setup, any help would be much appreciated.

Can I daisy chain like 3 of that and will that extend the operating hours of my modem router off grid?

@jimmatrix7244 Год назад

Bro, could you do a similar project to "POWER UP" laptop? Disregard or assume internal laptop battery is spoiled. Excellent projects!

Does it auto switch to battery mode? I have a sliding door project which works in 12V 5A. Can I use this system as the battery backup for my project?

@odoohub5010 9 месяцев назад

What is the purpose of the mosfet and resistor you used in this version. Because in the older versions i didn't see mosfet or resistor in them

@asad325able 2 года назад

@Open Green Energy Instructable link is old. and also in description 2S BMS is mentioned. What amp 3S are you using? And in description you mentioned XL-4019 so where you used it? and you haven't mentioned LM2577-LM2596s in description. Description contradicts with video

@opengreenenergy 2 года назад

Hi, You are correct. I have to update all the details.I am traveling now, so just copied the description from my V3.0. Sorry for the inconveniences.

Can I use solder instead of spot welder, to get desired cell configuration? Do not want to spend that much amount just for spot welding untill and unless it is very crucial.

@opengreenenergy 2 года назад

Yes, you can solder

Can this be used as a double conversion UPS. Is it possible to have power on all the time to the UPS and then when the power goes down it takes over supplying power. Then it can charge itself when the power comes back on. Like set and forget. Should be able to smooth spikes and sags?

@EnriqueMagdalenoHeredia Месяц назад

Hi friend, excellent work, very clear and interesting. Do you have a video to build the box for this project? I´ll be very thankfull with you. Waiting for your answer.
