Materials for renewable energy course (GUC)

1. HYBRID ELECTRIC VEHICLE Solar Electric Vehicle Done by ] ] ] ] Farag Aktham Abdullah Islam

2. Conventional cars

3. Internal combustion engines It has fuel tank which supplies gasoline to fuel engine. Engine turns a transmission which turns to wheels

4. Internal combustion Engines 1. consume Resources 2. Heavy reliance on imports Production shortages Petroleum is expensive 3. Creates smog & Ozone in Big cities 4. Emits pollution in the Air

5. Why electric cars ?

6. Electric cars are FUN! CLEAN AIR – zero emissions Electricity is readily available E lectricity costs are stable and much lower than gasoline Oil independence ( national security) S ave gas = save money L ow maintenance Fun, Fast, Clean & Efficient Why Electric Cars?

7. How Electric Cars? Electric Vehicle Energy Lingo WHAT YOU NEED TO KNOW kWh is “how much” energy, similar to liters of gas. Kilo Meters per kWh, similar to Kilo Meters per liter. kW is “how fast”, similar to liter per minute. kWh = how much energy is used or stored kW = how fast energy is transferred

8. Anywhere Where to find electricity for Electric Cars?

9. Disadvantages

10. Types of EV Battery Electric Vehicles fully-electric vehicles with rechargeable batteries and no gasoline engine.  Hybrid Electric Vehicle combines a conventional internal combustion engine (ICE) propulsion system with an electric   propulsion system

11. 3. Solar Power Car Solar power cars are electric cars which are powered by sun’s energy

12. How Does Solar Power Car Works

13. Evolution of Solar Power cars 1990 1993 2001 2009 World Solar Challenge Tübitak Formula-G

14. 2015 …….

15. Project aim Aim of the project : Using solar energy to enhance the efficiency of the car so that we can drive it for a longer time. Sustainable movement by supplying battery with electric energy while moving through PV

16. ELECTRONIC & ELECTRICAL COMPONENTS A solar car composes of the following PV solar panels Maximum Power Point Trackers (MPPT) Battery and Battery Management Systems Motor and Electronic Motor Controller

17. The Internal Process 48V battery Solar array voltage (i.e. voltage produced by the solar array) must be equal to system voltage of the motor for optimal working of motor. Generally, it is difficult to match these voltages accurately due to random errors MPPTs allow the system to run as efficiently as possible by sampling the output of the cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions. Direct Current Motors. to provide the power for propulsion converts electric energy to mechanical energy (motion) to drive the electric vehicle.

18. BATTERIES The batteries store energy from the solar array and make them available for the motor’s use . Batteries that are commonly used in solar cars are Lead-acid batteries, Li-ion batteries, Ni-MH batteries, Ni-Cd batteries, Flooded-cell batteries and Gel-cell batteries. Lead Acid Ni-Cd Battery Li-Ion Battery NiMH battery 4 * 12 Volt @ 12Ah Series Connection Lead acid deep cycle batteries Rechargeable Charging time 6-8 hours

19. Motor & Controller Efficiency of brushless DC motors is 95-98%. DC motors are cheaper than AC motors. Controller is an electronic device that controls the amount of power delivered to electric motor according to the signal from the potentiometer connected to throttle pedal.

20. PV specification : Supplies the baseline power required to the vehicle, recharges the batteries Series we will get 4 PVs each one has the following specification : Volt Watt 16 10 4 x 16 = 64 Volt 4 x 10 = 40 Watt

21. Vehicle Casing A Metal roof was designed to carry the PV panels to be in a fixed horizontal level in order to absorb sun rays during the whole day

22. Length 1,150mm Width 1,100mm Height 1,600mm Chassis weight 61 kg Battery Weight 19 kg Loading Capacity 1driver Estimated Range 2 km Climbing Ability (with loading 150KG) 20 degree Rating Output 1.0 kW Battery Lead Acid Battery Specs 48V12Ah Brake Disk Charging Time (0-100%) Recovered by 7 hours (more) Tire Size 3.25-6.25 General Specs

23. procedures we have charged the battery of the car till it become full , then we have estimated the distance which the car can be used using those batteries. we will make iron grid so we can put the PVs on it we will fix it to the car using welding method We will try to completely evacuate the batteries from electricity. we will leave the car in the sun so the batteries become full through using the new charging source " the sun " we will drive the car again so we can get the new distance which the car can go with the solar panels and then we will compare how the car will be affected through using the solar energy instead of electric energy

24. Expected finishing date : we recommend to use high capacity motor next time as the motor become much more hot every short time and this forced us to wait more than one time to cool it OR we can make cooling system for the motor Recommendations : Maximum 3 weeks from this presentation day

25. One day,solar car will be irreplaceable
