Everyday electronic applications involve the use of electric energy to do work. The increase in the supply of electric appliances has put enormous pressure on the electricity demand. In most remote locations with equipped electronic applications, DC power is required for their functionality, and thus batteries also play a vital role in terms of energy storage. Rechargeable batteries are extensively used as backup power in applications that require constant use, but these batteries can become quite worthless without a battery charger. Telecommunication applications provide an essential role in transmitting and receiving information in a variety of places, and as such, to enable constant use of power supply to those instruments, a battery charger with correct battery specification for charging and discharging becomes very handy.
Therefore, the proposed design of an automatic 12-volt battery charge controller for telecommunication applications is paramount during the disruption of the main power source and enables the further run-time for these telecommunication appliances to operate smoothly. It details the experimental aspect of the design to the component level, and software-based simulation to test the working of the prototype to be within a specific control limit for charging and discharging of the 12-volt Lead-acid battery.
