The catamaran, called Ecocat, is constructed of aluminum and was launched in Cantabria, north of Spain, in March
. He now undergoes tests to verify that he respects the promises of the designers. The plan is to test it in the Mediterranean this summer.
The catamaran has two 50-kilowatt engines and eight 30.5-kWh batteries each, four in each hull.
On the roof are 120 solar panels to help power the battery pack totaling 244 kWh.
Solvinger
The shipyard developed a pneumatic system that "widens" the roof to increase the solar surface when the ship sails. is able to navigate in 6-7 knots for eight hours "unplugged" – it will be without energy other than the sun can contribute before the ferry needs to be unloaded.
The catamaran is eight meters wide, weighs 26 tons and is supposed to have space for 120 people and a lot of bicycles.
Eliteserie
Norway plays in a slightly different division with several battery bins and a hybrid tourist vessel, the Vision of the Fjords, and the twin entirely Electoral vessel, Future of the Fjords
The Fjords are 42 meters long The future of the Fjords in operation between May and Flåm
It can last 2.5 hours at 16 knots with 400 passengers on board. Propulsion is provided by two 450 kW engines each and the power is stored in two 900 kWh batteries from Zem Energy.
BMW batteries
Ecocat is equipped with the same type of batteries that BMW uses, but marinated by German Toreuedo.
The energy management system of solar cells to batteries and electric motors was developed in collaboration with Torqeedo. Neither the court nor Torqeedo had the experience of such a system before.
The project was presented to the Spanish press in December
In a video recording of the press conference, the CEO Enrique Arriloa of Metaltec Naval says that the companies are based on the experience of previous projects, Ecobus-boat and Hybrid-cat. in Europe
– We have made many technical developments that inspired us to build this first Ecocat. It will be the first fully electric passenger powered solar powered passenger car in Europe, "says Arriloa in the December video.
In March, a new video will be presented. Then Ecocat was sown and the first sea samples were taken in Santander Bay, just painted in Raos (Cantabria).
– It is not a prototype or a prototype, but a full-fledged ship ready for commercial use
The director announces in a video that the company will build a new catamaran with bigger electric motors, two tires and a larger passenger capacity from the first sale.
According to the director of the shipyard, the primary market of the Mediterranean is that of activities in vulnerable areas
German supplier
Torqeedo declares that the company has delivered the two Torqeedo Deep Blue engines of 50 kW. They will provide a maximum speed of 9.7 knots for the 26-tonne heavy vessel.
Torqeedo has BMW marine-engine batteries of the same type as those used in the BMW i3. The batteries are air cooled. In order to ensure sufficient cooling, a "cooling chamber" is built in each shell. According to Torqeedo, water cooling would require extensive piping and more water.
Software collaboration
Torqeedo's CEO Christoph Ballin reports on the company's websites that Metlatec and Torqeedo engineers have collaborated to develop software for capture, storage and an optimal energy flow.
– It was a pleasure to work with Metaltec, a pioneer in the development of hybrid-powered batteries.
Since 2005, Torqeedo has been supplying electric motors running on water. The motors range from 0.5 kW to 100 kW. The company is part of the Deutz group.
Ecocat is launched in northern Spain in March 2018.
