Regenerative Braking Demonstrator on a Bicycle

Approx. component budget: Rs. 8,000 - 13,000

Objective

Measure how much energy can be recovered when braking from different speeds and compare it with the energy used to accelerate.

What you will build

A bicycle or a bench-mounted wheel with a hub motor or generator, a battery or supercapacitor, a controller, and sensors for speed, current and voltage.

Results you can expect

• Recovered energy vs speed
• Regeneration efficiency
• Braking distance with and without regeneration
• Charge gained over a test cycle

What you will learn

Regenerative braking, energy conversion and EV drivetrain basics.

Tools and notes

Arduino with current/voltage sensors, Excel. Use proper fuses and insulated wiring, and test on a stand or safe flat ground.

Resume points from this project

• Built and tested Regenerative Braking Demonstrator on a Bicycle; objective: measure how much energy can be recovered when braking from different speeds and compare it with the energy used to accelerate.
• Measured and analysed recovered energy vs speed and regeneration efficiency; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
