This initiative proposes a new battery charging device. The fundamental concept is to keep this project up-to-date by restricting charge time. The new constant loading technique is proposed and it has a digitally operated loader. Also, the adapter transfers control mode to continuous voltage charging with the battery voltage increasing to the default voltage mark. For battery charging applications, a digitally controlled charger is developed and introduced. A digitally controlled charger for battery charging applications is developed and introduced. The operation of the loader is subject to the proposed software control system. The closed-loop PID control also guarantees optimum electricity voltage. Three stages are used with the digitally controlled charger. The first step is to change the electric volume of 50 Hz to the DC volume with an appropriate power factor. The second phase is the DC-DC fly-back converter, changing the battery to its level and generating galvanic insulation. Step 3 uses digital power to keep the current and voltage stable. The project’s key aim is to maintain a steady voltage and current. The simulation is performed using Simulink with the MATLAB file Experimental findings show design and execution efficiency.
