This paper illustrates the method and calculation needed to hybridize the automotive, and to set up an energy storage system including the Lithium-ion batteries for same. All is done to boost the efficiency moderately of the vehicle. Alternate advantages of the process will include diminished emanation, scaling back of the motor, control sparing (regenerative power) and so forth. In a nutshell, the process will result in a hybridized automotive having better mileage with reduced outflow and be more vitality effective. The motive for undertaking this paper is to partially hybridize the above-mentioned vehicle to achieve the goal of high fuel economy. As a rough estimate, fully hybridized vehicles lead to the fuel saving of 20-35% depending on the efficiency of the battery and power control system.
