    Background[edit]

    Bicycle dynamos are nothing new, but charge-while-you-ride technology has improved by leaps and bounds in the last few years.These days you can charge just about any device that uses USB power using your own physical exertion, including smartphones, tablets and rechargeable lights.

    problem statement[edit]

    Design a charge device that can fast charge just about any device that uses USB power using your own physical exertion, including smartphones, tablets and rechargeable lights.

    deliverable&specifications[edit]

    charge smartphone fast.

    portable and reliable cellphone charging

    ensure enough power and steady voltage.

    goals[edit]

    designing a phone charge that uses power generated from the bicycle. A normal phone usually use 5V charge and a USB. So our goal is to able generate electricity from the bicycle that can give an out put of 5V by using a USB output. As a group project, we have pinpointed our design constraints, we divided the project as 3 parts: generator, DC-DC converter(to constant the variable input), battery. And we will focus on designing the DC-DC converter.

    Budget[edit]

    Design[edit]

    data collection[edit]

    The average power generated by a person is about 150W at 120 Rpm. Highest power that an cyclist reached is 1100W at 320 rpm. while selecting parts a higher power rating is preferred.

    Important Using Devices[edit]

    capcitor
    This capacitor is super-capacitor,it has large capacity, but it can't load a high voltage.We use a combination of several super-capacitor to get a high capacity and load the voltage we need.
    generator
    A generator with high power ratings so that the genartor is not damaged during high speed and which can also generate voltage during low speed is selected.so we need a generator that works around, 800w,24v,400rpm. This generator is a high torque and low speed.This model reach 12 volts at 120rpmm this make sure that the generator can supply enough energy.
