The car body is made of carbon fibre and the entire car is supported with double Wishbone Suspension and four wheels with low rolling resistance tyres.
Solar Car “SunSPEC2”
The team of 20 students from two schools design and fabricate a solar powered car that utilizes solar energy to power its motor for the maximum energy efficiency. The project required students to design a mechanically stable structure that can support 800W solar panels, an electric motor, electric systems such as energy storage, charge controller and control circuits. The car participated in Shell Eco-Marathon Asia 2012 and won the GOLD in the solar car category.
Solar Car “SunSPEC1”
The students made and designed the first prototype of solar car that can capture solar energy for generating electricity and driving a car. The solar car was powered by 560W solar panels and driven by a motor and battery bank. The electronic control circuits were used to control speed of car and gain maximum energy efficiency.
Smart and Micro-grid system
Smart MicroGrid Development(industrial project)
In collaboration with ST Kinetics, students designed and developed the modern microgrid electrical power system that integrated multiple energy sources, energy storage, and power electronic controllers to supply various loads in a lab in an efficient and reliable way. A web-based real-time system monitoring and control, as well as data analysis were included in the system.
Mobile Power Solution(industrial project)
In collaboration with ST Kinetics, students designed and built a smart mobile electrical power supply system that integrates a diesel genset, solar PV modules and energy storage to meet local power requirements with high energy efficiency and high power availability. The system was useful to various civil or military applications, e.g. in general urban community or remote area functions, disaster relief or peace keeping etc.
Optimising Home Energy With DC Microgrid
In the project based on modern DC microgrid technologies, students have designed and built a prototype home electrical energy system that is able to not only saving energy but also promote healthy living in a fun gaming way.
REAP – Responsible Energy Advocates Programme
Students help “above-the-line” households to perform energy audit and incorporates a combination of behavioural change and energy saving fitting to deliver reductions in the energy consumption after a period of 3 months monitoring.
Students who participate in the program find it meaningful and it also help them to re-look into their own energy habits.
2-seater Solar Powered Golf Buggy (industrial project)
The Buggy is an essential transportation vehicle in the golf course and the life of the battery is only 2 - 2.5 years. The Battery life affects the Return of investment of the buggy and one of the major component of the maintenance cost comes from battery replacement. A Joint Feasibility Studies Project is proposed involving Singapore polytechnic, NCI Golf Pte Ltd and SANYO ASIA Pte Ltd. The key objective is to design a Solar Buggy so as to extend the life of batteries and to save energy usage.
6-seater Solar Powered Buggy (industrial project)
In collaboration with JTC Chinese Garden, the students designed a solar system to power a 6-seater buggy for the Garden to conserve the energy use from power utility, prolong the lifetime of expensive batteries and reduce maintenance cost.
Solar Powered Tricycle (industrial project)
In collaboration with Sanyo, the students designed and built a solar powered tricycle consisting of a 195W solar panel mounted on top of the tricycle and the rechargeable battery for energy storage. The system can convert the sunlight directly to electricity for a rider to run the tricycle on the road.
Care for the needy
Hybrid Powered Scooter
Students have converted a normal lead-acid battery powered scooter into a scooter with hybrid power that integrates solar PV, fuel cell and Li-ion batteries for improved driving range as well as high acceleration capacity.
Fuel Cell Powered Wheelchair
Students have designed and built a fuel cell powered electric wheelchair which runs on clean and green hydrogen energy with longer driving range and faster charging time as well as easier joystick controller as compared with normal lead-acid battery driven wheelchairs.
Intelligent Water Energy Conservation System
This project utilizes Arduino platform to design an intelligent shower water system to conserve the precious water resource.
Saving water is indirectly conserving energy as to water purification and treatment requires energy.
The system will monitor the water usage and influence the users’ behaviour via electronics display with alarm and water prohibition measures.
It is an especially important concern as our society in Singapore is immersing into ageing population.
Renewable energy projects
Regenerative Fuel Cell System(R&D project)
In collaboration with NTU, students designed and developed a computer monitored and controlled regenerative fuel cell energy system that was able to automatically generate and store hydrogen which supplies a fuel cell to produce electrical power whenever needed. Supplied by renewable energy, the system becomes self-contained and sustainable.
Solar Powered Fan
The students use one solar panel to harvest the solar energy and drive two DC fans directly without energy storage battery. The solar powered fans can be used for outdoor activities to cool down the participants and make them comfortable.
Bicycle Power Generator
The aim of the project is to design a bicycle power generator that allow cyclist to convert his/her own energy to electricity for powering up a series of sequential lighting while practising cycling.
Solar Powered Tent
The project aims to design a mobile solar powered tent for people to get electricity in outdoor activities like camp or during natural disaster like Tsunami and quake. The tent is equipped with LED light, DC fan and electronic mosquito expeller.
Portable Race Track for Solar Car Race
The project designed and fabricated a portable racetrack for Mini Solar Competition. The system equipped with automation control system can automatically start the race and work as a time keeper’s to record the running time for the solar car.
Solar Garden Tree
This project is about building a Solar Garden Tree that has solar panels to charge a battery during day time and light up LED light bulbs automatically at night to illuminate the garden. This tree has eight branches each with a 18V, 5W solar panel,a 12V and 24Ah battery and 4 LED bulbs of of 12V, 0.3 amps each. The bulbs are wide angle with 60 degrees spot beam angle. The tree had a charge controller to charge the battery and a timer to automatically time the ON and OFF of the LED lamps.
Solar Trash Compactor
This project is to build a solar trash compactor that compresses the trash once it reaches a maximum level making room for further trash and thereby increasing the capacity of the trash bin. It also reduces the carbon emission by reducing the number of trips made by the transport in clearing the rubbish.
