Problem Statement
To build a self charging electric skateboard that is lightweight and fun.
Project Summary
The electric skateboard is a skateboard driven by an electric motor that has the ability to recharge itself. The skate’s deck is made of low-density foam wrapped in composite. The skate is designed to accommodate the electrical components within the deck. This will prevent dirt and water from fouling critical electronics. The deck will have vents that will allow air to circulate and cool the electronics. A carbon composite would be ideal for the construction however other composites would be acceptable.
A DC motor will drive the rear wheels of the skate. The motor will drive the wheels via a geared connection that will allow motion in the rear trucks. The skate will have a battery pack that will be rechargeable. To recharge the battery the direction of the motor will be reversed, creating a generator.
To operate the skate, there will be two buttons incorporated into the skate deck. One button will be the drive button the other the brake. When the drive button is pressed the DC motor will run forward and drive the skate. When the brake button is pressed, the DC motor will run in reverse and charge the battery. If neither button is pressed the skate will coast freely. The buttons will be placed near the tail of the deck and will be operated by slight movements of the skater’s foot.
The skate will have a max speed of about 10mph and will have a range of 10 miles. An electric motor will drive the wheels and regenerate the 24V battery. This 3ft long skateboard with 4in diameter wheels will weigh less than 50lbs. The skate deck will be made of a composite material bonded with epoxy. Total cost of the skateboard will be $300.
