Regenerative Braking Test Bench for a DC Motor

Approx. component budget: Rs. 6,000 - 10,000

Objective

Measure how much energy can be recovered during braking and what limits it.

What you will build

A DC motor with a flywheel load and a bidirectional converter that can recover braking energy into a battery or supercapacitor.

Results you can expect

• Energy recovered as a percentage of kinetic energy for 5 stops
• Braking time
• Battery current profile
• And effect of initial speed

What you will learn

Regeneration, bidirectional converters and energy flow in electric vehicles.

Tools and notes

DC motor, flywheel, H-bridge or bidirectional buck-boost, battery or supercapacitor, current sensors, Arduino. Fit a mechanical guard and a fuse.

Resume points from this project

• Built and tested Regenerative Braking Test Bench for a DC Motor; objective: measure how much energy can be recovered during braking and what limits it.
• Measured and analysed energy recovered as a percentage of kinetic energy for 5 stops and braking time; 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.
