EVs are increasingly being acknowledged not just as a mode of transport, but as versatile energy assets capable of bidirectional energy transfer. This innovative approach allows EVs to act as mobile energy storage units; they can store energy when demand is low and discharge it back to the grid when demand peaks.

Moreover, the integration of EVs with energy storage can facilitate smart grid technologies. By coordinating EV charging with grid needs, energy consumption can be optimized, and renewable energy can be effectively utilized. For instance, consumers can charge their vehicles during off-peak hours, when electricity is most affordable, and sell excess energy back to the grid when prices are higher. This not only allows for more effective use of renewable energy but significantly reduces overall energy costs for consumers.

In addition, aggregating multiple EVs can create a substantial energy resource that can be leveraged to support grid requirements. This aggregation can be particularly beneficial in community settings, where numerous EVs can act together to provide grid services and enhance energy resilience. Such advancements indicate a promising future where transportation and energy generation/storage are seamlessly integrated.
