A battery charger is an electrical device employed for charging batteries. These batteries that are usually charged by battery charger are the storage batteries also known as “accumulator” the battery charger changes. The alternating current forms the power line into d.c suitable for charging. When the battery is fully changed, is up to it’s maximum, 12 volt, the charger with automatically cut-off with the help of the contact relay […]

Battery or bird cages are homes for domesticated birds. Birds require a house in which they can fly and have some freedom but still ensure they do not fly away. Bird cages are constructed to be large enough to accommodate the motion and daily activities of domesticated birds. This work was carried out to build a bird cage using available materials.

Car battery level monitor indicates the status of the battery just by glowing LED’s. This work explains you how to design battery level indicator. You can use this circuit to check car battery or inverter. So by using this circuit, we can increase the lifetime of battery. The heart of this battery level indicator circuit is LM3914 IC. This IC takes input analog voltage and drives 10 LED’s linearly according to the input analog voltage. […]

This project focuses on the design and construction of a pure sine wave inverter system, which produces an output that closely resembles the quality of mains power. Unlike many inverters that generate a modified sine wave, which is less efficient and inferior to the standard 240V mains supply, pure sine wave inverters deliver a true sine wave output. This ensures not only the proper functioning of high-end electronic devices but also s […]

This work is on a lithium battery charger which is designed to charge lithium batteries and other portable devices. This charger gives constant current and constant voltage for charging battery and also the voltage range and current value can be changed depending on the voltage of the battery under charge. It has an automatic charging feature which proceeds charging automatically when the battery voltage goes below the set value, and w […]
This project is titled design and construction of a battery charger using SCR. Automatic battery charger presented here is an acid battery charger that is designed to charge any acid battery using thyristor to supply the required current. This charger will charge any 12V lead acid battery including flooded, gel and AGM. It is fully automatic and will charge at a rate up to about 4A until the battery voltage reaches a preset point at w […]
