ABSTRACT (Objective)

To increase an electric car efficiency.

Here we are mainly concentrating on converting thewaste energy into considerable electric energy.

instead of friction energy used to apply brakes,backforce of dynamo can be used.

INTRODUCTION(Literature review)

Whenever brakes will be applied a shaft will come incontact with the axel and transfer the energy to agear system which increases its RPM which is furtherconnected to a flywheel. This flywheel is connectedto a dynamo. Due to rotation dynamo will produceelectricity and it applies some backward force which

will be used to stop the vehicle.

The electricity produced by the dynamo can be usedto charge a battery.

WORK DONE SO FAR (Review 1)

The initial step is to design the car and to collect allthe parts accordingly.

Car design is completed.

We have purchased chassis and wire. The second step is to get appropriate gear and

flywheel.

Review 2

Had purchased appropriate gears.

We had designed the model of our moving shaft.

The shaft is designed in such a way so that the disc,

attached to it help the shaft to rotate and it can moveto and fro in perpendicular direction.

The assembly is shown n the next slide.

We had purchased axel, gears, chassis, dynamo.

Review 3

The electricity is produced when brakes are applied.

The electricity produced can enlighten aroundenough LEDs at a time at only 80-100 RPM.

At 200 RPM of disc rotation 12V of potentialdifference is obtained.

The backforce on dynamo depends upon theresistance connected to the dynamo.

15 LEDs are connected in parallel.

WORKING (SHAFT)

Force is applied on the bearing

Bearing is fixed with the shaft, connected to the disc

When bearing moves disc will move and comes in

contact with the disc 2 Energy is transferred to the dynamo.

Spring will help it in disengaging the disc1 withdisc2.

RESULTS AND DISCUSSION

Dynamo is producing electricity after considerableRPM which can be used to charge the battery.

When brakes are applied the electricity is produced .

Spring will pull the disc when brakes are releasedand conversion of energy will stop.

The electricity produced by the dynamo is used tcharge the battery.

The battery is recharged thus the efficiency of anelectric car get increased.

ADVANCED MECHANISM

We can apply ABS system and automatic gear box in it.

The automatic gear system will change the gears according tothe torque supplied by the disc and its RPM.

If the person will apply full brakes the flywheel will apply

enough inertia so that the car will stop suddenly but at thesame time ABS system will decrease the friction between thedisc 1 and disc 2 so that the wheel will not slip on the road.

The gear box will engage the gear according to the RPM atwhich the disc will rotate.

With both of these technologies we need to have frictionbrakes too so that they will stop the car if the electric brakingsystem not works.


12/14

Result

The cost of the apparatus is quite low so it can beattached in any car or vehicle.

Efficiency of an electric car can be increased upto30%.

Waste heat energy is used.

Efficiency can also be used by attaching automaticgears after the pulley.


13/14

CONCLUSION

The electricity produced can be used to charge thebattery of the car and it can be reused. The efficiencyof an electric car is increased considerably.
