An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. [ 1 ] While a significant majority of water vessels are powered by diesel engines , with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years.
It can be used for any electrical ship application up to 20 megawatts and operates at a nominal voltage of 1000 V DC. The DC distribution system is simply an extension of the multiple DC links that already exist in all propulsion and thruster drives, which usually account for more than 80 percent of the electrical power consumption on electric ...
The 31-metre boat is covered by 537 m 2 [6] of solar panels rated at 93 kWp, [7] which in turn connect to two electric motors, one in each hull. [2] There are 8.5 tons of lithium-ion batteries in the ship's two hulls. [8] The boat's shape allows it to reach speeds of up to 10 knots (19 km/h). [1]

The 20-metre-long and 7-metre-wide boat is covered by 140 square metres (1,500 sq ft) of solar panels rated at 20 kW, which in turn connect to two electric motors of 20 kW, one in each hull. There are 700 kg of lithium-ion batteries in the ship's two hulls with a total capacity of 50 kWh.
Shore power or shore supply is the provision of shoreside electrical power to a ship at berth while its main and auxiliary engines are shut down. [1] While the term denotes shore as opposed to off-shore, it is sometimes applied to aircraft or land-based vehicles (such as campers, heavy trucks with sleeping compartments and tour buses), which may plug into grid power when parked for idle reduction.
