<div class="section abstract"><div class="htmlview paragraph">With increase in number of EVs on Indian roads, poised EV makers to produce innovative and pragmatic concept of electric vehicle features. The concept of bidirectional charging is one of that and which is creating buzz and curiosity among EV buyers. The bidirectional charging enables EV owners to lend the power to grid, other vehicles or use for other auxiliary applications. This paper focuses on idea of vehicle-to-vehicle (V2V) level 1, level 2 AC charging using J1772 standard, and level 3 DC fast charging using ISO 15118 or DIN 70121. where one user can lend a range of few kilometers to other based on requirement as a helping hand. This paper proposes a new idea which enable vehicle-to-vehicle (V2V) charging using ISO 15118, DIN70121 and J1772 protocol. In V2V charging, source vehicle shall function as a mobile charging source (EVSE) and other shall function as a sink (EV). The idea of making source vehicle as charging station involves sink vehicle authentication and managing the power flow. This paper discusses the overall system level architecture involving need of mobile or remote charging, sources vehicle willingness, V2V authentication, charging request, power flow control, and charging execution.</div></div>
