As the population increases and the cities get bigger, the use of bicycles is more common in today’s society. More and more people are relying on bicycles as a means of transportation in big cities. Creating a small electrical system is more and more important for the riders to use their phones and other electronic devices. Energy harvesting from the bicycle will enable the operation of the small electrical system.
The project aims to design a energy harvesting system to power the electronic devices for the riders. The system includes a DC motor attached to the bicycle, electronic controller and a battery storage.
The specifications of the project are:
1) Design mechanical system to attach the DC motor to the bicycles. The DC motor should be able to output a maximum power of 20W.
2) Design an electronic converter to convert the power from the DC motor to be a regulated 5V output.
3) Design a power bank using 18650 battery to store the energy. The power bank should be able to output 10W each via two USB ports.
The group should investigate the DC motor available in the market to determine the proper mounting mechanism to the bicycles. The group should be familiar with the power electronics DC-DC converters to regulate the output voltage. It also necessary to know the operating principle of the power bank.
The group should be responsible for project management, project demo and project reports.
Student A is responsible for the design and selection of DC motor.
Student B is responsible for the mounting mechanism of the DC motor to the bike
Student C is responsible for the DC-DC voltage regulator
Student D is responsible for the design of power bank.
