Project Goals:

To successfully power a commercially available electric bike withsolar panels. The bike is to be stored in a shed with the panel(s) mounted

on top.Electric bikes and scooter are available for purchase today. These

vehicles are normally powered by a rechargeable battery pack that is plugged into a wall outlet after the batteries drain.

This projects goal is to give additional charger that is powered bysolar panels. This would require minimal cost to sustain operation (i.e.no cost for gasoline).



Tentative Bill of Materials

Electric Scooter

Battery Type: Dual 12 volt, 10 amp/hour, rechargeable battery pack

Motor Type: 24 volt.Recharge Time: 3-7 hrs (with wall outlet charger)

Top Speed: 20 Kmph (appx.)

AP-30 SOLAR PANEL

More than 1.8 amps charging current in full sunlight

Open Circuit Voltage: 21.5 volts

Max Power Voltage: 16.7 volts



Timeline

Project Start Date: 24 august 2010

Parts: 3-5 weeks (circuit design, selecting parts, delivery time)

Assembly: 5-7weeks

Testing: 3-5 weeks

Estimated Project Completion Date: February 2011



FINANCIAL SUMMARY

ELECTRIC BIKE 10000 RS.SOLAR PANEL 5000 RS.CHARGE CONTROLLER 1500RS.OTHERS 4000 RS.



Ongoing Activities:

Correspondence with electric bike dealers and solar paneldealers.

Budget acquisition and preparation for purchases.

Researching in the area of charging circuits.

Parts yet to be ordered.

PROJECT STATUS



Charger Details

The scooter has dual 12 volt, 10 AH batteries connected in series,charged by a 14 volt, 1.2 ± 1.5 amp wall outlet charger.

The solar panels provide more than 14 volts, and more than 1.2A, so the circuit in between the scooter and panels should limit thecurrent and voltage should they get too large. Also, the new chargingcircuit should prevent the overloading of the batteries. If the output fromthe solar panel dips (cloudy day), the batteries will just take longer tocharge. This simplifies circuit design.

Different charging circuits are being researched and one thatmeets the requirements will be selected / created.



OUTCOMESThis is a practical vehicle for single person.The range is about 40 km. & top speed is about 15-20

kmph depending upon the weight of rider.This is a vehicle for transforming our consciousness abouthow we use energy.



Project Benefits

There are many benefits to using solar power. Solar power is free, it just needsto be harnessed. After the initial investment, the solar scooter will pay for its self.

Operation of the scooter will be simple. After being taken out for a ride, theuser will simply have to put the scooter back in its shed and plug a wire in. No going tothe gas station required. The scooter will charge its self and cease charging when the

batteries are at full load.

A scooter like this is ideal in an area where destinations are relatively close

together, like a small town or dense city. In a city, electric scooters would cut down on pollution, traffic in the streets, and use of gasoline.

This type of alternative energy has the capability to greatly reduce emissionsand dependence on foreign oil.
