This paper is an implementation of a secondary battery inside the cars so that the charged battery can be used to power the appliances when needed. A battery system is designed to crank the engine either from the primary battery or the secondary battery. In this battery system design, the alternator and the battery are directly connected in parallel configuration meaning the alternator charges the battery and powers the components or just charges the battery depending on the consumption, this means that the alternator has to run right from the start of the engine to the minute the car stops so why don't we charge another battery by a system which can be toggled on or off by a switch depending on the need, the system in the below paper does exactly what mentioned above.
