An Experimental Test Model for an Electric DC Power Boat Design

This paper presents an experimental test model for DC power input to an electric boat reaching a desired speed to provide a theoretical understanding of DC electric power-driven propulsion, which is the replacement of combustion engines. This paper recommended a parameter “power coefficient” for electric boat design as an important indicator. While traveling at a desired speed and the power supply voltage is stable, the motor drive current is a key parameter to achieve the best power coefficient. Such a parameter can be realtime monitoring according to the natural properties of the DC powertrain in electric boats.
