Abstract: The paper devises an off-grid charging class for electric vehicle (EV) and hydrogen vehicle (HV). Electric and hydrogen vehicles are charged at similar period. Outcome ability of solar method is divided into two elements. Solar ability is employed to provide electrical charge requirement and remaining energy is directed on water in electrolyser which is transformed to hydrogen. Hydrogen is accumulated and it provides hydrogen load requirement. Fuel cell is integrated with the charging power plant to deal with such uncertainty. Proposed multi port DC/DC converter is examined with regard to operating rules and power flow. Voltage relationship between ports is also derived. The energy from all input sources are delivered independently. It can also be delivered in mixed form and in single stage which leads to greater efficiency. The efficiency and feasibility of introduced system are shown using the outcome from simulation.
