Dc Battery Charger-Usage, Working, And Charging
The critical power centre is a battery system for your recreational vehicle. To ensure that the power center is fully charged and maintained for as long as possible, it is necessary to make sure that you are fitted with all the equipment. There's a DC charger that comes into the picture!
In any recreational vehicle power management system, a DC battery charger plays a pivotal role. This form of charger brings the characteristics of a conventional AC (main power) multi-stage charger to the off-grid touring environment. A DC charger can draw power from your alternator through your starter battery while your engine is running and will charge your auxiliary battery safely.
If you're hunting to know everything about the dc battery charger, then you are standing on the right page. What all you need to do is scroll down and read on.
Can you use a battery charger as a DC power supply?Yes, you can use a battery charger as a DC power supply as there are cases where a battery charger can need to act as a power supply and maintain batteries. This could be when configured for UPS (Uninterruptible Power Supply) or when checking or running a battery-powered DC system.
Now we know that a battery charger can be used as a DC power supply, let's look at the places you can use it.
●Medical Cart: A medical cart with a sealed lead-acid battery but with a low power drain on some applications can be a candidate for a switch-mode charger like the corresponding voltage unit and amps. Without being in the boost mode, the Charger will charge up to its present rating and drop to the current load level and be safe for long-term battery management until it is unplugged/removed.
●Larger current drains: The Samlex units are always used for larger current drains. It can supply these for aircraft and R&D applications, where technicians or engineers want to test avionics without exhausting the battery system. Apart from this, OEM car manufacturers and equipment manufacturers with Samlex units to be part of a trade show, an auto show, or even a SEMA display, where vehicle or equipment electrical systems are operated for hours on end for demonstration purposes.
●Electronic Applications: There are also applications for electronic/radio. It is possible to set up a radio repeater station (smaller DC powered units) with a battery bank powered by a charger. The batteries feed the device when the power goes out. When the power is restored, the charger recharges the batteries while the device loads.
How does a DC battery charger work?The response to the question "How does a DC battery charger work" can be easily understood through the following points:
●A battery charger is actually a DC power supply. Here a transformer is used to lower the input voltage of the AC mains to the appropriate level as per the transformer's rating.
●This transformer is often a high power type and can produce high current output as expected by most lead-acid batteries.
●To rectify the AC in DC, the bridge rectifier configuration is used, and a high-value electrolytic capacitor smoothes it.
●The DC is supplied to an electronic circuit that controls the voltage at a constant level and applies it to the charge battery, where an internal chemical reaction process stores energy.
●A voltage sensor circuit is integrated with automatic battery chargers to sensor the voltage of the charge battery. As battery voltage exceeds the appropriate optimal level, the charger is automatically turned OFF.
Can you charge two batteries with one charger?For long-term projects and energy savings, battery reloading can prove convenient. The way batteries are charged using a battery system involves an electrical circuit to charge each battery. In order to find out how your batteries can be charged with a charger, you can also read about the circuits in question.
Here we explain how to charge batteries in alignment, so you can build electrical circuits to use the way the chargers work to charge batteries properly.
1) Charging Batteries in Series
Determine the total voltage of the battery. When connected in series, battery voltages are cumulative. The current is the same, however. For instance, five 12-volt serial battery systems have a total voltage of five times 12 or 60 volts.
Use a single charger to charge up to 5 batteries to have a higher charging voltage. Versions are available in 12, 24, 36, 48, and 60 volts. A 60-volt charger can charge five 12 volt batteries. At one end of the series and the other end of the series, apply the necessary voltage charge to the positive terminal. The time to charge a single battery is exactly the same.
Charge over five batteries using a 12-volt battery charger connected to each set of batteries, as if each battery was the only one charged. Load the two batteries simultaneously. If you charge only a few batteries, they will attempt to equalize power and charge each other, impacting the battery's life.
2) Charging Batteries in Parallel
Confirm the parallel battery circuit. Both positive ends of the battery are attached to a single wire, and all negative ends to a different wire are connected. Regardless of the number of batteries, the total voltage remains the same, but the batteries have a cumulative current output. For example, six parallel 12-volt batteries still supply 12 volts, but the battery lasts six times longer than one battery in one battery.
Connect the battery charger to one end of the row between the positive (+) battery terminal and the negative (-) battery terminal on the other end of the row. It ensures that the batteries are charged on an equal footing. Connection to one battery works but is less effective if this is not possible.
Multiply the approximate time for charging the total number of batteries with one battery. For example, if it normally takes 3 hours to charge the battery and five batteries attached, the charging time will be 5x3 hours or 15 hours.
ConclusionSo, here you have come to the end of the article in which you got a basic understanding of DC battery charger, how DC battery charging works and how you can quickly charge batteries in series and parallel. Hopefully, the step-by-step guide given above will support and assist you with all your needs!
