Introduction to Electric Vehicles
See how battery energy becomes motion.

WHAT TO EXPECT
Follow the complete energy flow from battery to wheel—and explain what every major EV component does.
A four-hour, hardware-led workshop where students explore a real EV powertrain, watch it come together, and apply what they learn in a team design challenge.
THE WORKSHOP IDEA
Don’t just study an EV. Watch one come alive.
One real drivetrain anchors the entire session. Students touch the parts, predict what each one does, watch the system come together, and follow energy all the way to motion.

THE PROGRAMME FLOW
Each idea powers the next.
Guess the EV componentsBattery and charger · BMS and controller · Motor and throttle→
Students meet the hardware before the slides. They handle each part, decide what it might do, and identify the engine, energy store, accelerator, controller, and safety system.
- Battery and charger
- BMS and controller
- Motor and throttle
Why electric vehicles came backEarly automobiles · Why EVs disappeared · The modern revival→
A fast, question-led story connects the first automobiles and early EVs to petrol, diesel, the modern EV revival, and India’s changing mobility landscape.
- Early automobiles
- Why EVs disappeared
- The modern revival
Energy you can pictureVoltage and current · Power and energy · What changes vehicle range→
A water-tank analogy turns electrical terms into something students can see: voltage is pressure, current is flow, the motor is a water wheel, and the battery stores usable energy.
- Voltage and current
- Power and energy
- What changes vehicle range
Build an EV powertrain liveBattery → fuse → switch · Controller → motor · Throttle → motion→
The instructor connects the drivetrain one component at a time. Students predict each part’s role before the system is powered and the throttle spins the motor.
- Battery → fuse → switch
- Controller → motor
- Throttle → motion
Open the motorBrushed vs brushless · Torque and speed · Why magnets resist motion→
After seeing the drivetrain work, students compare brushed and brushless motors and inspect the rotor, magnets, windings, bearings, and available Hall sensors.
- Brushed vs brushless
- Torque and speed
- Why magnets resist motion
Build the battery idea18650 cell anatomy · Series and parallel · BMS protection and balancing→
Students physically arrange demonstration cells to see how one cell scales into a pack, then use series and parallel layouts to understand voltage, capacity, and energy.

- Series and parallel
- BMS protection and balancing
Press the acceleratorThrottle and controller · CC/CV charging · Regenerative braking→
The class retraces the complete signal and energy path—from a foot on the throttle to the wheel—then explores charging and how regenerative braking turns a motor into a generator.
- Throttle and controller
- CC/CV charging
- Regenerative braking
Design an electric scooterChoose the battery · Match motor and controller · Estimate range and charge time
Teams choose the parts for a simple vehicle brief, explain their decisions, and finish with a rapid quiz and a short team presentation.
- Choose the battery
- Match motor and controller
- Estimate range and charge time
FLOW COMPLETE
Students finish by using the complete system—not isolated facts—to make and explain an EV design decision.
LIVE DEMONSTRATION LAB
See the hardware answer the question.
Demonstrations are selected to suit the available training hardware and the age group in the room.
Direction
Reverse the motor and see how electronic control changes direction.
Voltage and speed
Compare input voltage with the motor’s visible response.
Torque vs speed
Use motor KV ratings to discuss two competing design goals.
Inside the controller
Find MOSFETs, capacitors, and the heat sink inside an ESC.
Charging
Follow the constant-current and constant-voltage charging stages.
Measure it
Use a multimeter to check battery voltage and continuity.
Find the fault
Inspect a deliberately incorrect, unpowered connection.
SAFE HARDWARE PRACTICEBattery-pack concepts are taught with protected demonstration hardware and instructor supervision. Students arrange and inspect components; they do not weld live cells or fabricate high-energy packs.
