Development of an Energetic System Model for Long-Tail Electric Boat combining Solar Panels and a Prototype of E-Engine

This paper proposes the prototype of e-tail and the energetic system model for all electric long-tail boat equipping with solar panels. It offers many advantages over a traditional internal combustion engine (ICE) propulsion system, thanks to the combination of the electric powertrain and the solar panel. Besides low noise and zero-emission, characteristics of electric engine allow regenerative braking and starting the propeller in the water. The prototype of e-tail is presented. The energetic system model is built to sizing optimally the battery capacity depending on the consumption of the e-tail boat driven by the e-engine. The simulations results are performed on a testcase of Phong Nha cave tourism boat. With 5 solar panels and 4 kWh of battery capacity, the boat can operate independently without external power source at least 1 round-trip 4 days in a week in winter and maximum 2 trips per day every day in summer.
