In light of global warming, automobile power systems are becoming more and more dependent on clean, renewable energy sources like battery and fuel cells. This paper looks into the viability of a hybrid electric vehicle, fuel cells, and batteries. both approaches are more significant to the proposed as discussed. A finished Hybrid Electric Vehicle system, which includes the electric. The vehicle's power-train system, control system, and power system are all modeled in a Matlab/Simulink environment. A fuzzy logic-based control system has designed. The development of an energy management strategy (EMS) with the goal of maximizing power of the battery, Regenerative Braking System is charging the battery when it applies. And various types of state-of-charge levels to provide the battery. According to the simulated results of the functional test, which involved idling, accelerating, and cruising at different fuel cell and battery states, the anticipated vehicular power system and the EMS perform rather well. By modelling a particular driving vehicle test in three common circumstances, the power system then demonstrates that it operates effectively and adaptably under the management of the EMS and exhibits superior fuel economy than utilizing a widely-adopted power-following control technique.
