Solar-Assisted Electric Boat Power and Propulsion System Simulations

Abstract

This paper created a digital representation of an electric boat’s power and electrical system to have an insight of the boat’s operation using the electrical components that will be installed in the electric boat. Having these insights will give the ability to explore options regarding the boat’s operation. A model of individual electrical components has been simulated and interconnected to mimic the boat’s operation. The power-speed curve of the electric boat was also curve-fitted to get the equation for ship powering. By comparing existing boat operation in the area, given the speed, the corresponding required power can be determined. Results show that the components selected is adequate for the boat’s operation. Results also show that improvements can be made with the solar assist system, addition of battery bank capacity while considering the battery weights, and strategic placing of charging stations along the deployment site and commencing charging while waiting for passengers.
