3. Introduction
• The first Hybrid Vehicle (HV) was introduced in 1899 by Dr.
Ferdinand Porsche, and was known as the Lohner-Porsche Mixte.
• Advances in Internal Combustion Engine (ICE) technology, however,
condemned HV technology to the background, only being revived
periodically (albeit infrequently) throughout the 20th century.
• The HV has been popularized with the introduction of the Honda
Insight in 1999 and especially the Toyota Prius in 2000.
• “A road vehicle that can draw propulsion energy from both of the
following on-vehicle sources of stored energy: 1) one or more
consumable fuels and 2) one or more energy storage systems that
is/are recharged by an electric motor-generator system, an off-vehicle
electrical energy source, or both.” - Hybrid vehicle

4. Literature review
• Mathematical proof of efficiency enhancement in use of HEV and
approximate mathematical model of EV in terms of Power, Energy,
Force etc. are presented in this paper.
• Feasibility of HEV with Bidirectional Half Bridge DC-DC Converter
as charger and Brush less DC (BLDC) motor, is presented in
MATLAB simulation at prototype level of power scale 10:1 range
with practical data of components.
• The dynamic modelling of vehicle performance which specify ratings
of components like electric motor, battery, power converter controllers
etc.
• With the advancement of Li-ion battery, energy storage system for
HEV and EV also uses this technology for implementation in this high
demand of transportation system due to large growth of population.

5. Methodology
• To implement this, a mathematical proof in terms of efficiency
enhancement in HEV compared to conventional ICE engine is
presented first.
• After this theoretical proof of efficiency enhancement, an approximate
mathematical model is presented in terms of power, energy, force, etc.
which are needed to design the component ratings (like charger power
handling capacity, motor peak torque etc.) of vehicle.
• After designing the rating of components, the feasibility of proposed
concepts is implemented in small scale prototype MATLAB Simulink
model to check and analyze results obtained from the approximate
mathematical model.

7. • It is assumed that it has the
operation of an hour
approximately in which static
mode of operation with 30 km/h
and 40 km/h occurred for 30
minutes each
Under dynamic mode of
operation with zero to 40km/h
speed in 10 sec (accelerating
mode), from 40km/h to zero
speed in 5 sec (braking mode ),
20 times each i.e. total 5
minutes duration of dynamic
operation.

9. • In this controller part speed of
vehicle is compared with the
reference speed (speed
regulation method) to
generate the gate pulse for
one switch and
complementary of this switch
pulse is given to other switch
as shown.

14. Conclusion
• The first objective of this article is to clarify the nomenclature of HVs
and PHVs in order to include some powertrain configurations that
were excluded by the previous definitions. New definitions were
proposed that correct the omissions and inclusions of powertrain
configurations and that improve the clarity and correctness of the
definitions.
• In this work, It has been investigated that the efficiency of HEV by
using approximate mathematical modeling and the analysis of HEV
with approximate mathematical model reveals that the model is
helpful for determining the components rating of electric drive system
like electric motor, battery etc. which further make easy the
implementation of HEV for suitable routine of vehicle operation.
