A better option for V2G and G2V compatibility is a bidirectional dc/dc on-board charger for EV battery discharging/charging application. Isolated converters favour working with high power densities over a wide variety of loads, which is advantageous for EV applications. For all power switches in both directions, the bidirectional converter executes the stepup and stepdown operation at zero voltage switching. There are two different types of architectures—direct and indirect architectures—that can be used to link EVs to the grid. The EV and the grid system operator only have one communication channel to use under the direct architecture. The indirect architecture, on the other hand, calls for communication between the grid operator and a middle system (sometimes referred to as an aggregator). In this essay, we focus on the earlier design. Electric vehicles (EVs) engage in continuous charge-discharge cycles when they connect to the grid to carry out various V2G services. The expense related to the EV batteries’ deterioration needs to be examined and assessed, therefore these cycles may be of major concern to the owners of the vehicles. In light of this, the battery cycle life (CL) must be taken into account while talking about the battery’s deterioration.
