Abstract
Many places with high population density, such as New York City and Los Angeles, often navigate their cities using Ubers or Metros. These services can get costly when used on a daily basis, so many people walk, or, for longer distances, use skateboards or bicycles. These modes of transportation are suitable for some, but for most, it can be a tiring process that leaves them in a hot and sweaty condition that one would not want to be in when going on a date or interviewing for a job. As a way to combat this undesirable state, developments towards motorizing these skateboards and bicycles have been heavily pursued. These developments have been well-accepted by the public and continue to increase in popularity. It is for these reasons an electric bike was chosen to be the final design project this report will discuss. The e-bike for this project will be designed for intercity travel. For a better understanding of how the power system of an e-bike operates, a battery pack will be designed and manufactured to the specifications of a 36V 15W brushless DC Hub Motor. Along with the battery pack will be a BMS and ESC to regulate the voltages and currents of each subsystem. The subsystems will include a safety system, LCD display and GPS module.
