 INTRODUCTION TO ELECTRIC VEHICLE

• An electric vehicle (EV) is a car that runs entirely or partially on electricity instead
of gasoline. The electricity is stored in reusable batteries and used to power an electric
motor that turns the wheels.
• Electric vehicles are categorized as follows:
• Battery Electric Vehicle (BEV): It runs entirely on electricity with no gas engine. They can
travel distances ranging from 80 to over 300 miles on a single charge.
• Plug-In Hybrid Electric Vehicle (PHEV): It has both electric and gas components. It can drive
20–55 miles on electricity before switching to gas.
• Fuel Cell Electric Vehicle (FCEV): It uses hydrogen fuel cells to produce electricity. It has a
300–400 mile range and fast 5-minute refuel times.
• Compared to gas-powered cars, EVs are more efficient. They have lower operating costs
and produce no tailpipe emissions, making them better for the environment.
 COMPONENTS OF ELECTRIC VEHICLE
• The major components of an electric vehicle (EV) include:

• 1. **Electric Motor**:The electric motor is the heart of the EV, responsible for propelling the vehicle.There are
several types of electric motors used in EVs, including induction motors, permanent magnet motors, and switched
reluctance motors.
• 2. **Battery**:The battery is the primary source of energy for the EV. Electric vehicles use rechargeable lithium-ion
batteries, which can be charged from an external power source or regenerative braking.
• 3. **Onboard Charger**:The onboard charger converts the alternating current (AC) power from an external
power source to direct current (DC) power for charging the battery.
• 4. **Power Electronics**:The power electronics control the flow of electricity between the battery, motor, and
other components, ensuring efficient and safe operation.
• 5. **Thermal Management System**:The thermal management system regulates the temperature of the battery and
other components to maintain optimal operating conditions and prevent overheating.
• 6. **Electric Control Unit (ECU)**: The ECU is the brain of the EV, controlling the flow of electricity and monitoring
the vehicle's systems. It also communicates with other electronic systems and performs various functions such as
regenerative braking and traction control.
7. **Charging Port**:The charging port is where the vehicle is connected to an
external power source to charge the battery.
8. **Traction Control System**:The traction control system ensures that the
vehicle's wheels have adequate traction and stability on various road surfaces and
driving conditions.
9. **Regenerative Braking System**: The regenerative braking system captures
some of the kinetic energy generated during braking and converts it back into
electrical energy, which is stored in the battery.
10. **Safety Features**: Modern EVs often come equipped with advanced safety
features such as anti-lock braking systems (ABS), electronic stability control (ESC),
and airbags to ensure a safe driving experience.
11. **Air Conditioning and Heating System**: The air conditioning and heating
system maintains a comfortable cabin temperature for passengers.
12. **Infotainment System**: The infotainment system provides entertainment,
navigation, and connectivity features such as Bluetooth, Wi-Fi, and smartphone
integration.
13. **Steering System**:The steering system provides a smooth and responsive
steering experience for drivers.
14. **Braking System**: The braking system includes components such as brake
pads, rotors, and calipers that work together to slow or stop the vehicle.
15. **Suspension System**:The suspension system absorbs bumps and vibrations
from the road surface, providing a comfortable ride for passengers.

These are some of the major components that make up an electric vehicle.
Depending on the specific design and manufacturer, there may be additional
components or variations on these components.
 ELECTRIC MOTOR

The core element of the EV,

apart from Electric Vehicle
Batteries, which replaces
the Internal Combustion
engines is an Electric motor.
The rapid development in
the field of Power
electronics and control
techniques has created a
space for various types of
electric motors to be used
in Electric Vehicles.
 SYCHROUS MOTOR CONTROLLER

• A synchronous motor controller is a device used to manage synchronous motors. Let’s dive into the details:
1.Synchronous Motor Definition:
1. A synchronous motor runs at a constant speed synchronized with the supply frequency.
2. It’s commonly used for applications requiring consistent speed and power factor improvement.
2.Speed Control Factors:
1. The motor’s speed depends on the supply frequency and the number of poles.
2. Adjusting the frequency is the practical method for speed control.
3.Methods for Speed Control:
1. Inverter Fed Open Loop:
1.Uses a variable frequency inverter without feedback.
2.Suitable when precise speed control isn’t necessary.
3.Main supply → rectifier → inverter → motor.
•
 JUNCTION BOX

The Battery Junction Box (BJB) is a

switching unit for the battery in an electric
vehicle. It connects or disconnects the
components in the vehicle, which need
energy from the battery.
With one or more bus interfaces, this
component is networked with the entire
vehicle. The BJB is usually a switching box
that switches the high-voltage connection
on or off. It ensures that the high voltage
is only applied to the necessary
contacts when the ignition is switched on.
 COOLANT PUMP

• The powerful electric coolant pump PDE circulates

the coolant in order to cool the battery and the
powertrain. Its performance range is also designed
to meet future battery cooling requirements during
fast charging.
 TOOLS USED IN EV

•Pneumatic gun
•Torque wren
•Spanner
•Socket
 WHAT IS PNEUMATIC GUN
• A pneumatic gun, also known as an air-powered tool or pneumatic tool, is a type of
power tool that uses compressed air to generate torque and tighten or loosen nuts and
bolts. Here's how it works:
• **Basic Components:**
• 1. **Air compressor:** The air compressor is the heart of the pneumatic gun. It
compresses air to a high pressure (usually between 90-120 PSI) and stores it in a tank.
• 2. **Air hose:** The compressed air is stored in an air hose, which connects the
compressor to the pneumatic gun.
• 3. **Pneumatic gun:** The pneumatic gun is the tool that uses the compressed air to
tighten or loosen nuts and bolts. It typically consists of a handle, a chuck, and a nozzle.
• 4. **Chuck:** The chuck is the part that holds the nut or bolt in place while the
pneumatic gun applies torque.
• 5. **Nozzle:** The nozzle is the part that directs the compressed air into the chuck.
WORKING DIAGRAM
 TORQUE WRENCH

• A torque wrench is a tool used to apply a specific torque to

a fastener such as a nut, bolt, or lag screw. It is usually in the form of
a socket wrench with an indicating scale, or an internal mechanism
which will indicate (as by 'clicking', a specific movement of the tool
handle in relation to the tool head) when a specified (adjustable)
torque value has been reached during application.
• A torque wrench is used where the tightness of screws and bolts is a
crucial parameter of assembly or adjustment. It allows the operator to
set the torque applied to the fastener to meet the specification for a
particular application. This permits proper tension and loading of all
parts.
• Torque screwdrivers and torque wrenches have similar purposes and
may have similar mechanisms.
