Assignment - Design of a Solar Racing Car

Learning outcome 1: Demonstrate the following knowledge and understanding

Demonstrate the following knowledge and understanding: Differentiate and critically evaluate system structure, working principles, performance analysis and optimisation of various sustainable energies and application technologies.

Learning outcome 2: Demonstrate the following skills and abilities

Demonstrate the following skills and abilities: Design and develop various sustainable energy systems, and analyse and optimise the performance of various sustainable energy systems.

Design Your Solar Car
The power needed your car is:

Power = resistance x speed = (0.01 x mg + 0.5 x Cd x ρ x A x V2) x V

Here, m is your car's mass; g = 9.8 m/s2; Cd is your car air drag coefficient which is dependent on your car body design; ρ is air density; A is your car's projected frontal area; V is your car speed.

For making your car to cover as long as possible distance/range with as high as possible speed and necessary acceleration, you need develop your solar PV power supply system, the battery (5 kWh), the electric motor and control system to meet the requirements. You need to demonstrate your design in a Word file as a technical report.

Tasks

1) Check the websites of ‘World Solar Challenge' and some teams, to learn the regulations and relevant technology, then list some points of important regulations and technical issues relating to your design. (Max 500 words)

2) In accordance to the competition result of 2019 World Solar Challenge, to plan your car's max speed, max acceleration rate and max daily range. Then working out required max power and required electricity amount (included 5 kWh pre-charged electricity in the battery and produced from the solar PV panels). You need estimate the effects of your PV system and electric system (battery, E-motor, controller, etc.) on the vehicle mass.

3) Design your PV system including selecting PV panels from exiting market, analysing their output under various weather conditions and under different sunshine time (morning to noon to evening), detailing the installation of PV panels on your car with necessary diagrams or drawings, develop their connection and controller. Then estimate the total mass of the PV system.

4) Select your battery from existing market with a max capacity of 5 kWh, select required E-motor, gearbox and controller from existing market for meeting the requirement of power and rotating speed. Estimate the total mass of the electric system.

5) Make a simulation (using Python for your programming) to check if your design meets your target for covering adequate range with adequate speed during a normal sunshine day. Present your results with necessary figures in your report.
