Abstract: Solar cars are energy-sensitive and affected by many factors. In order to achieve optimal energy management of solar cars, it is necessary to comprehensively characterize the energy flow of vehicular components. To model these components which are hard to formulate, this study stimulates a solar car with the digital twin (DT) technology to accurately characterize energy. Based on the hybrid modeling approach combining mechanistic and data-driven technologies, the DT model of a solar car is established with a designed cloud platform server based on Transmission Control Protocol (TCP) to realize data interaction between physical and virtual entities. The DT model is further modified by the offline optimization data of drive motors, and the energy consumption is evaluated with the DT system in the real-world experiment. Specifically, the energy consumption Citation: Bai, L.; Zhang, Y.; Wei, H.; error between the experiment and simulation is less than 5.17%, which suggests that the established Dong, J.; Tian, W. Digital Twin DT model can accurately stimulate energy consumption. Generally, this study lays the foundation Modeling of a Solar Car Based on the for subsequent performance optimization research. -

Creative Discovery Museum Lesson Plan Biofuels Outreach Lesson “Farming for Fuel”
Creative Discovery Museum Lesson Plan Biofuels Outreach Lesson “Farming for Fuel” Time Needed for set-up (45 min. to 1 hr.) Class time - 1 hour This series of activities is designed to be presented as an inquiry-based lesson introducing the concepts connected with creating biofuels and the need to change to alternative energy sources for transportation. Each activity could be taught individually if the intent is to cover the concepts in depth instead of as an introduction to the topic. This lesson is designed to consist of a 15 minute introduction including the carbon demonstration and experiment followed by 5 student activity centers through which the students rotate for approximately 5 minutes each. That is then followed by a 5 to 10 minute wrap up of the concepts introduced. Possible recording sheets can be found at the end of this plan. Target Age/ Audience: Grades 4 – 8 Main Concept: Alternative energy sources, with an emphasis on biofuels made from non-food plants, are appropriate for transportation. Using alternative energy sources does not add as much CO 2 into the atmosphere as using fossil fuels does, and the carbon cycle can remain more balanced. A non-food product for fuel is important since food shortages often occur around the world. Objectives of the Lesson: (These objectives can be written on cards and placed at each center to encourage greater comprehension by students .) • Fuel production from the fossil fuel sources, which are quickly being depleted, currently in use are more harmful to the environment because carbon dioxide they release a greater amount of CO 2 into the atmosphere. -

B.E, Dept. of Mechanical Engineering, Jay Shriram Group of Institutions. Tiruppur, Tamilnadu, India ABSTRACT: The project is about to power up the electric cars and achieve the maximum distance of running. The electric car most commonly seen in the roads but the main problem of electric vehicle are there is no continues recharging sources, so we implementing a new project on electric vehicle by using solar power and dynamo. The solar power can be produced from the sun light by using the solar panel and the dynamo will convert the mechanical energy to electrical energy from wheels of the vehicle. It can be used to avoid the plug in charge. We design the solar power hybrid electric vehicle model by two software. The chassis and frame work analysis are done by using the ANSYS work bench and the energy calculations which are done by using 2016A mat lab. This type of technique is to reduce the running cost and increasing the running efficiency of the vehicle. The performance of the vehicle was found to be satisfactory for the load of four people with the average speed of 60km/hr. By using this we can be able to reduce the all kind pollutions and the fuel economy. The main systems that we are using are PMDC motor, solar module, Charge Controller, Batteries, Boost Converter, Step-down Transformer; Diode Rectifier Experimental results are presented to confirm the theoretical analysis. -
Construction Tips
Construction Tips When you begin designing your solar car, a few ideas must be taken into consideration to maximize the speed of the vehicle, including the following: 1. Weight of the solar car 2. Direction of the sun 3. Addition of Reflectors 4. Setting up the Guide Wire There will be tradeoffs when designing your vehicle. For example, a lighter car in weight will go faster than a heavier car. However, adding reflectors that increase the weight also can increase the power output (increases in the power may lead to an increase in rotation per minute (RPM)). It is highly recommended that you test your vehicle several times with a guide wire before the day of the race to ensure all components remain attached and your eyelet does not prevent the solar car from traveling the length of the course. One last note to remember is that mistakes are OK! Learning from our failures is part of the process to creating a successful solar car. Weight of the solar car: There is no limit to the weight of the vehicle in the regulations, however, a larger weight will cause more friction between the wheels and ground which will result in lower speeds and the larger weight results in a larger inertia to overcome, decreasing the acceleration. Think about the type of materials you would like to use to increase the speed as much as possible. Be as creative as possible and attempt to use recycled materials, they will earn you points during the holistic review of your solar vehicle. On another note, if you decide to add reflectors on your vehicle, consider the minimum amount of weight that will lead to the highest power outputs. -
