Charger for car batteries with their hands – it's easy
It is understandable that the battery charger is a kind of analog of an electrical device for generating energy. In order to ensure its operation in a safe mode, a relay (regulator) must be installed on the circuit after this generator. Its task is not to allow excess of the evaporation rate of gases in the battery. Thus, the charging voltage is about 14 Volts (+ - 0.2). That is, we can see that in order to assemble a charger for a car battery, you only need to observe a few simple rules and adhere to the schemes proposed to you further.
Charger for car batteries with his own hands: the most popular scheme
The most common circuit consists of such components as a heating element and a diode. Thus, you need to connect the diode and the heating device you selected (no more than two kilowatts) to one circuit. After that, you will have about four amperes on the network. Charging under this scheme will take no more than fifteen hours, and the total energy consumption after it will be about 15 kilowatts. Such a scheme has only one minus. It has only one percent of the overall efficiency. And that's why this battery charger is the simplest and most popular, but not so good.
Also you can make a charger for car batteries yourself with the help of transistors. To do this, you will need thyristors, which also connect one circuit to the network. In this scheme there are also small drawbacks. The resulting charger for car batteries emits too much heat radiation, and, if you mix up the polarity of the battery, it will fail. In addition, this scheme is not able to ensure the stability of the charging process. However, this method, nevertheless, is quite popular. And the radio interference that is created by such a device can easily be minimized by wearing a special ferrite ring for this purpose.
Scheme chargers for car batteries, done with the help of capacitors
If you plan to make a charger for car batteries with your own hands using ballast capacitors, then you definitely need a video master class that can in detail and step by step tell about how and what needs to be done. This you can see, for example, in this video
Since in the car charger made with the help of capacitors, the current stability is achieved due to not only the power transformer, but also the type of capacitors (C5-C9). Accordingly, the larger the capacitor you choose, the greater the current flow will be applied to the battery. However, it is worth remembering that if the contact with the terminals is broken, the transformer will fail.
After reading this article, you learned about several of the most popular schemes that will allow you to make a charger for car batteries yourself. However, remember that any wrong or careless movement, especially when your device is already under tension, can lead not only to unpleasant health effects, but also to the battery of your car.
