A review on Hybrid Electric Vehicle and simulation on Hybrid Electric Vehicle Drivetrain Abstract

Mild EHV: - This kind of EHV also has both power sources but here the vehicle cannot work independently on the electric propulsion, here the vehicle mainly runs by both source of power at same time, but it can work at ICE independently. Example: - “Honda Accord Hybrid”. they are limited to parallel mode, so they work only on series mode.
Plug-in EHV:- This kind of EHV also has two power source and can run independently on electric or ICE but here the battery of electric propulsion system is not charged with the ICE but it is charged by the external charging plug that’s why it is named Plug-in EHV. Mainly the Plug-in hybrid have more capacity in battery then in Full hybrid and they range is also higher than the average Full hybrid. They can work on both series and parallel mode.
There are some other types of EHVs which are not common in use like high-performance hybrids which are used in high performance cars such as “Ferrari”, “McLaren”, Etc. These Automobiles companies uses this hybrid technology to boost cars performance unlike others they do not focus fuel efficiency and they focus on performance maximization. They use the hybrid electric motors to assist the engine to maximize performance to the vehicle they use the hybrid electric technology in completely opposite way.
The Hybrid Electric Vehicles are fuel efficient than conventional vehicle because of less emission generate due to electric motors. And they are cost-effective and affordable also, compared to conventional vehicle. The ICE required in Hybrid Electric Vehicle is lighter than the conventional one, so it makes the Vehicle lighter and more spacious. the Vehicle also decreases fuel usage which increases the driving range of the vehicle. The Hybrid Electric Vehicles are also more preferred than pure Electric Vehicle (EV) [3] due to performance compromise in EV, EVs are costly and requires electric charging stations for charging which are not available outside the cities, obviously lesser emission are there but the time required for charging is 10-12 hours compared fuel engine which is too much. but in Hybrid Electric Vehicle, charging stations are not required for charging the battery, but it is charged by the generator, which is connected to the engine, so the power gets reused by electric motors to accelerate the vehicle. The Hybrid Electric Vehicles mainly are built for economy, so there is a compromise of performance in some Hybrid Electric Vehicles, the Hybrid Electric Vehicle also increases the maintenance of the vehicle because of complex components used and mainly due to electronic components requires skilled experts for the maintenance.
