2. This presentation will discuss the hybrid electric vehicle
(HEV) transmission system and explain how it works. We will
explore the various components of the system and how
they work together to create a reliable and eefficient
drive train for electric vehicles.
Introduction: The History And
Development of Electric Cars:

3. • How Does an HEV Transmission
Work?
The HEV transmission system works by allowing the electric
motor to power the vehicle in most conditions and allowing
the ICE to take over and increase power when needed. This
combination allows for superior fuel efficiency and
improved performance. The HEV transmission also allows
for regenerative braking, which captures and stores kinetic
energy from braking and uses it to power the vehicle.

4. • What is an HEV Transmission?
HEV transmissions are special transmissions designed
speci cally for electric vehicles that combine a traditional
Internal Combustion Engine (ICE) with an electric motor.
This combination allows for superior fuel e ciency as well
as increased power when compared to ICE powered
vehicles. The combination of both systems also allows for
improved performance and better acceleration.

5. Electric vehicles are powered either by a direct-drive system
or by di erent types of transmission systems. The three
main types of transmission systems utilized in electric
vehicles are single-speed, variable-speed and CVT
transmissions. All these transmission systems act as a
bridge between the electric motor and the drive axle for the
electric vehicles.
The Three Types of Electric Vehicle
Transmission System:

6. The electric vehicle transmission system consists of a number
of components such as the battery, electric motor, controller,
driving unit, di erential/gearbox, wheels, and drive axles. The
battery stores the power generated by the engine and
provides the electricity required by the electric motor to drive
the vehicle. The controller regulates the motor's power output
and regulates power to the wheels, while the drive unit
transmits the power to the wheels. The di erential and
gearbox further reduce the speed and provide torque to the
wheels while driving. All these components are essential to
the working of an electric vehicle transmission system.
The Component of an Electric Vehicle
Transmission System:

7. •How an Electric Vehicle Transmission
System Works:
The electric vehicle transmission system works by transferring
energy from the battery to the wheels, thus enabling the
vehicle to drive. The electric motor is powered by electricity
stored in the battery which then powers the wheels through
the controller and drive unit. The di erential and gearbox
further reduce the speed and provide torque to the wheels.
Together, these components work together to power the
electric vehicle and make it move.

8. •What are the Benefits of an
HEV Transmission?
The HEV Transmission system many advantages to
electric vehicles, including fuel-efficiency, better
performance, increased safety, and regenerative braking.
Additionally, it makes electric vehicle technology more
a ordable and accessible, allowing more people to access
the bene ts of electric vehicles.

9. Despite the numerous advantages of electric vehicle
transmission systems, there are some drawbacks. High
initial cost is the main disadvantage associated with an
electric vehicle transmission system requiring considerable
investment. Additionally, the battery technology is still in its
nascent stage of development and an electric vehicle will
require frequent recharging depending on its rate of usage.
The Drawbacks of an Electric Vehicle
Transmission System:

10. •The Future of Electric Vehicle
Transmission Systems:
Increasing popularity of Electric Vehicles and its advantages
have led researchers to further invest in the development of
transmission systems. This is expected to reduce the cost of
the system and make it more e cient in the coming years.
Along with the focus on creating e cient battery
technology, electric transmission systems are projected to
o er great results in performance.

11. • Conclusion:
The HEV Transmission system many advantages for
electric vehicles, such as fuel-efficiency, better performance,
increased safety, and regenerative braking. Additionally, it
makes electric vehicle technology more a ordable, allowing
more people to participate in alternative transportation
methods.
