a) Battery Pack
Stores electrical energy in the form of DC
(Direct Current)
b) DC-DC Converter
Steps down high voltage to run auxiliary systems
(lights, dashboard)
c) Inverter
Converts DC from the battery to AC for the
electric motor
Block Diagrams and Layouts in EV
V. P. Bhaurkar EV (T. Y. Mechanical)
d) Motor Controller
Controls the motor’s speed and torque using
inputs like accelerator
e) Electric Motor
Converts electrical energy into mechanical power
to drive the vehicle
f) Transmission
Transfers torque from the motor to the wheels,
with or without gears
g)Wheels
Final output — vehicle motion
