Let’s build a small battery savings. In an era of expensive energy better. In an era that energy is more expensive every day. Alternative energy is a good solution, to solve immediate problems, or renewable energy to do the work well. Solar energy is an alternative that we can use another kind. For this project, we use it to charge a small battery, we must first understand the working principle of the circuit before. How it works. Battery charger with solar cells consists of three parts are… 1. The solar cell panels are used to change a sunlight energy to electrical energy into direct current. Normally we would put solar panels are connected to each other. Until the voltage level as needed. Which, has the principle same battery, is sunlight cell series to increase the current. And this current production, depending on the geographic location, temperature and the amount of [...]

When you want to create form lead-acid battery charger circuit. Although there are many methods to choose from. I like using IC LM317 Because easy to use, with minimal equipment. Cheap and good. Today, I try to collection ideas for the battery charger circuit. This is just part one. There are 4 circuits, as follows. 1. The universal battery charger using Lm317 Here comes very simple idea is the universal battery charger circuit. When, an input power is applied to the circuit. The SCR1 (Silicon controlled rectifier) turn off, then not has a bias current path to ground. The LM317 acts as a current regulator, It is connected to the battery thought a one way diode D1, limiting resistor R1, and a bias resistor R2. The D1 prevents the circuit from battery discharging, when the power out off from this circuit. As the battery charges, the voltage across A point [...]
The best 12 Volt battery charger circuit our this is a charger circuit automatic system, then when the battery voltage is lower than specified, this circuit provides power to the battery immediately and stops charging when the battery is fully only. So ideal for use in emergency power supply or battery backup power system at all type. And certainly, if you apply to your car battery, it does not have any rules. And the most important is the price that was really very. we will quickly build is available. How this circuit works From the circuit will be seen that, in the heart is IC1 op-amp no.LM311. Which it is connected be the compared circuit. Usually the voltage at pin 3 will be equal to 6V with the Zener diode ZD1-6V. While the battery has a voltage charged in full. The output voltage at pin 6 to negative voltage across [...]
This is an automatic 12V battery charger circuit, they uses the power SCR and UJT are main parts. And they will not work except the battery 12V to be charged with right polarity, so prevent errors as well. The battery voltage controls the charger and when the battery is fully charged, the charger will not supply current to the battery anymore.
Ni Cad battery advantages in that charger to reuse again. And thus may itself be a disadvantage. Because if a user brought back a new charger while the residual voltage will cause the memory effect that this phenomenon is a result. reaction when the battery voltage volt battery to this level of power will not come out. And lifetime is shorter by Solutions using energy r up To secure the discharge by using a longer usage. This circuit is used to discharge the battery at a voltage bias to Q1 adjusted using VR1 serves volt bias to the base pin of Q1 is appropriate to bring the battery if the battery has voltage remaining Lamp. Light up until the battery runs out Lamp will gradually vanish if there is no battery power remaining lamp will not start.
