DIY Car Battery Charger From PC Power Supply

Sometimes, it pays a great reward to have the ability to control and to understand the processes and wonders of doing things with your own hands and time. And it has become a very popular option as the internet grows more and more interactive and as people get more information on how to do certain things.

This is even more apparent when you get to the topic of car battery chargers. There are many methods, for sure, and a good majority of them keep getting better and better. In this passage, we will get to know how to whip up a DIY car battery from PC power supply and understand the ins an outs within that solution. Overall, you may find that the solution is not so much complicated as it is intricate.

Most of the time, car battery chargers need to be operational on the range of 12-Volts. This is even more important if you wish to charge a large number of these car batteries at the same time. With a power supply that comes from a personal computer (PC), you can do that very thing (even works when using personal computer supplies that are rather out of date).

For that to work, you need to wire up your PC power supply with connector plugs to deliver DC (output) power to the car batteries. Not unlike other solution models provided for car battery chargers made at home, this can save you money but at greater convenience.

If you want to know more about how personal computer power supplies can get you cheaper rates of charging while at the same time, adding more flexibility for the services that you need, you can refer to the rest of this article below. You may find these reasons enough to give this car battery charger solution a good experimental run. At the very least, this could give you the blueprint to try out other energy suppliers for a more personalized, customizable experience.

Materials For A PC Power Supply DIY Car Battery Charger

Going through the materials you most likely will need, we can round up these curtains basics:

1. PC Power Supply and Outlets. Of course, without this, the whole process cannot start and be completed. But, we do not necessarily have to go with just about any pc power supply. Setting standards, we can look for those ideal to provide certain benefits such as multiple outlets for charging and also a higher watt percentage given for faster charger.

That said, here are some observations:

– Do not underestimate convenience. There are a lot of people around who do not have any use for their pc power supplies and most of them buy a new set along with their new personal computer sets. Take advantage of that and ask for specifications like watt output and how many that particular model can charge at a given time—a pleasant surprise may come.

– Do pay attention to ‘wattage’. Yup, a higher watt percentage or rate (around 350 watts is a good one) is a good sign for a power supply as it can spread out power to many facets or sources as well as give a huge enough charge, which is good when dealing with larger than normal car batteries. Wattage can also be substituted for terms like amps (around 20 amps is good, as well).

– Do ask if the pc power supply you are using has indeed certain standards attributed to a standard model and its functions. Certain aspects of that include (but not limited to) a protection system from short circuits and overloads. Counterfeits do come by every now and then, so become a wary investigator on this part—make sure.

2. Wires and Connector Plugs. This is very helpful when they come (often do) in a color-coded fashion. Here are some outtakes to have from current observations and the research:

– Do remember that there are two polarities that you need to concern yourself with when it comes to wires: a negative (-) and a positive (+).

– Do remember that these two polarities must be correlated with colored wire. In this case, a negative (-) polarity goes to a black wire and a positive (+) polarity goes to a red wire and/or a yellow wire.

– Do take heed that these wires have different voltage rates. Case in point, a positive (+) polarity red wire provides 5 volts and a positive (+) polarity yellow wire gives of 12 volts.

That is pretty much what you need to go about when it comes to the very basic materials needed.

A Sample DIY PC Power Supply Car Charger Process

Not so much an intricate or heavy laden process, but it does need a good amount of patience to consider a good number of things (for safety and success). Here are some things to take into that consideration:

1. The location of the chargers needs at least a yellow wire and a black wire (one of each). In case of a lot of wires present, you can join them up to fit charging stations. This gives off more power also through a more concentrated path.
2. Your pc supply will usually have a green wire that is placed a black wire to turn itself on. While in a normal pc situation, these would be used by simply pressing “on”. You, on the other hand, would need to use some sort of paper clip or material to act as leverage for your on and off switch.
3. The above steps would then need to be tapered with a platform to hold everything together. In most cases, you can use pieces of cut plywood.
The results will vary according to how much you spend on the design for your platform. But, overall, this should help you get started in having a DIY car battery charger from PC supply geared and ready to go. Stay safe and have fun experimenting.
