DC accumulator with all its possibilities as a power supply for drive circuits in electronic engineering and design. The battery is a source of DC energy (pure DC) as well as AC (if connected to an inverter circuit), the battery is an energy source for all systems that rely on DC voltage, namely all electronic and digital circuit systems as well as a mixture of them, we can see its application in the DC source on SMART HOME by regulating solar cells, also in control power systems in the automotive world, the aerospace world, and as a driving force for some of the drives in DC motors, servos and stepper motors which act as drivers for robot arms to create motion control for arms and grips robotic. For this reason, a system is needed to design how the battery can function properly and perform optimally, namely by always being able to observe the potential difference in the car's accumulator and being ready to trigger the charging system on the DC accumulator. DC accumulators are known to come in 2 forms, wet and dry, also a momentary concept. in dielectrics that we call capacitors or condensers. There are many battery charging techniques, one of which is by charging directly through an adapter with a 1 to 10 Ampere transformer, with a fast and precise charging speed, proper control of the current entering and leaving the battery during charging and recharging is required, always have instruments and measurements analog and digital as data analysis instructions.
