3. ✓ Four Core Components
• Battery bank ( lithium-ion
)
2
• Purpose built chassis 1
3
• Inverter
• 3 phase induction
motor
4

4. # Functions of parts
• Battery (all-electric auxiliary): In an electric drive vehicle, the auxiliary
battery provides electricity to power vehicle accessories.
• Charge port: The charge port allows the vehicle to connect to an external
power supply in order to charge the traction battery pack.
• DC/DC converter: This device converts higher-voltage DC power from the
traction battery pack to the lower-voltage DC power needed to run vehicle
accessories and recharge the auxiliary battery.
• Electric traction motor: Using power from the traction battery pack, this
motor drives the vehicle's wheels. Some vehicles use motor generators
that perform both the drive and regeneration functions.

5. • Onboard charger: Takes the incoming AC electricity supplied via the charge port
and converts it to DC power for charging the traction battery. It also communicates
with the charging equipment and monitors battery characteristics such as voltage,
current, temperature, and state of charge while charging the pack.
• Power electronics controller: This unit manages the flow of electrical energy
delivered by the traction battery, controlling the speed of the electric traction motor
and the torque it produces.
• Thermal system (cooling): This system maintains a proper operating temperature
range of the engine, electric motor, power electronics, and other components.
• Traction battery pack: Stores electricity for use by the electric traction motor.
• Transmission (electric): The transmission transfers mechanical power from the
electric traction motor to drive the wheels.

6. ✓ Parts of EVs

7. 1 # Two important material without which
electric car is not possible are
• Copper
• Nickel
✓ Points to remember

8. 2 # Glycol is used as a coolant in electric car
which is filled in pipes which are transferred
from between the batteries
✓ Points to remember

9. 3
# Regenerative braking system is used which
charges the batteries when we apply brake
^where brake pandal is connected to a motor
which charges the batteries
✓ Points to remember

10. 4 # Function of battery management system
BMS is to prevent disbalance between
batteries charging and discharging
✓ Points to remember

11. LOREM IPSUM DOLOR

12. √ Why EVs are better than IC Engine
1.90% efficient vs
30%
3. No noise vs high noise
and vibrations
2. Less moving parts vs more
4. Less heating vs high heat
and emissions
