Design and development of solar cells in electric vehicle prototype intended to Design and development of solar cells in electric vehicle prototype Case study electric cars of Rajamangala University of Technology Phra Nakhon. The research process begins with the solar experiment model Solar Thin Film a bent size 19.2 x 9.5 cm technology has applications in Unmanned Aerial Vehicle install to a source of clean electricity generation using 80 Solar Thin Film Cells controlled by Arduino mega size 101.52x 53.3 mm Programming software by Arduino-1.6.9-Windows and Show the result at LCD Solar Monitor Charger from batteries store the electrical energy size 12V/28AH 6 pack for the results showed that such a circuit can charge electricity 5A to 1 hour and to expand the use of rechargeable battery electric prototype instead of using electric vehicle prototype from charging normally Requires 480 Solar Thin Film Cells in trial period hypothesis 6 hour/day. In term of investment evaluation simple payback period is expected to be 4 years. Considering sensitivity analysis it is found that the most sensitive factor is electricity cost cost Solar Thin Film and the cost of Evlink Fast Charge Solution respectively. The results of this study can be used to support decision making in design and development of electric vehicle prototype in the next generation more efficiently

Nowadays car is one of important factors for the human life whereas critical traffic dramatically effects on risk of accident between cars and pedestrians. Therefore the road accident is the enormous loss of human resources. Regarding this problems the lifted mechanism of vehicle hood was concerned and installed on the vehicle hood simulator to mitigate the severe accident in this project. To achieve this the energy absorption was established to decrease the injury of pedestrians by the gap increase between the bottom edge of hood and the engine valve cover. This solution can increase the ability of energy absorption during an accident moment. There were 8 steps of hood gap in this study to in the experimental works indicated by Head Injury Criterion HIC from head-form. The testing program was referred by Pedestrian Protection Test Procedures in EURO NCAP. From the experimental works the increasing gap between the bottom edge of hood and the engine valve cover tends to decrease the values of HIC. By the lowest of HIC the 4th gap is 18 cm of space representing 90.17 and 208.06 of HIC15 and HIC35 respectively. In consequence of experiment the gap between the bottom edge of hood and the engine valve cover plays a role on the HIC value in which it can mitigate the severe injury of pedestrian on accidental way whereas the lifted up mechanism of hood are ability as conjecture.

The objective of this paper is to construct the solar car prototype. The car uses flexible solar panels with the battery as a power source. Thereafter the performance of the solar car is tested in the actual condition. This solar car’s body was developed by fiberglass and the internal structure was made from the steel. This car uses the 2 kW brushless DC motor to be the prime mover and the motor is driven by the regenerative dc converter. The power sources are 480 watts of the flexible solar panel with a charger to charge power to four of 12V 33Ah battery. The total weight of the solar car is 173 kg. The solar car’s weight including driver is about 233.4 kg. The solar car test drive is on 10 km distance. The result found that the car has: (1) the average speed is equal to 45.98km/h by using only battery (2) the average speed is equal to 51 km/h when the battery is combined with solar panels. This knowledge should be applied to develop the next version of the solar racing car.

This research is to study and develop a DC motor speed control by using Visual Basic.Net 2008 in computer programming to use the computer and the microcontroller is processing from computer via the serial port. So that a signal to the motor driver circuit motor speed work as assigned. By the speed can be entered via the computer screen is measured in rpm. and motor control to control the PWM (Pulse Width Modulation) control circuit and the principles of the hardware by using the digital output signal of the microcontroller control Motor speed can be configured to be from 100 to 3000 rpm. And the motor starts to spin at maximum speed and then gradually reduce the speed down to the specified value. Control both the speed and the average error of 4.6% compared to the speed measurement using infrared light. And found that at speeds below 100 rpm. to a maximum error of 12% and the error decreases when the speed increases. The error value is at least 2000 rpm. and 3000 rpm the speed error is 0.5%

This reseach presents development of engineering education about automation engineer. The objectives of develop education technology automatic control systems. The development and pilot institutions or company associated with the agency so that it can compete with companies in the ASEAN countries. In the design research and development training kit to support and use in teaching and learning control liquid level like an industry as the reality of the industry. The trainner could be applied to the advanced control theory for experiment in teaching or training in class room similary industry personnel. The hardware is compatible with existing standards. It is increase the capacity of existing courses such as a course to learn basic control system consists of a sensor industry around the outside parmerter. The sensor could be real measured and simulation from plant model. The student can control the virtual experiments. Controller could be learning such as PLC Microcontroller and computers. The experiments determine relation of correlated response signal ON-OFF and PID by adjust Gain control systems that have tenor as same as control theory which describes the response of the control. The experimental results of this the research collected in the operating room. The ability to control the system to could be doand meet the taget and follow by objective
