Nidec asi electric power solutions for hybrid propulsion

  2. 2. Electric Propulsion Experience Leading the way to innovation: hybrid propulsion system Our proven experience to satisfy every custom solutions for marine propulsion and on board generation allow us to invest in innovation and develop new solutions which take into account both our costumers requirements and eco efficiency needs. The hybrid solution marks the beginning of a new phase in marine propulsion history. It guarantees CO2 zero emissions, agility in manoeuvres at low speed, silent shipping in inland sea without needing a separate on board generator to supply on board equipment. With zero emission electric power it is possible to reach the desiderable advantages useing only the electrical propulsion. PPT2013.01.01.05EN 2
  3. 3. Hybrid Propulsion Experience SHOWCASE: E1 zero emission boat for Venice Laguna Large cities represent areas of intense concentration in activities. These activities are the origin of the principal causes of environmental change both in a local and in a global perspective. Transportation is certainly one of the primary contributors to environmental pollution. Working in partnership with local passenger transport company A.C.T.V (Azienda Consorzio Trasporti Veneziano) we have developed and realized the dream of E1 boat, a new waterbus which complies with Z.E.B (Zero Emission Boat) program. The E1 boat carries 200 people throught the Canal Grande, reducing pollution emissions, noises and vibrations, guaranteing maximum comfort of the passengers, reducing the risk of erosion by wave wash - generated by ships - on Venice’s historic buildings. E1 vessel is based on an hibryd electric propulsion system with batteries, asynchronous AC motor (60 kW a 1300 rmp), variable frequency inverter. This combination represents the best solution because asynchronous AC motor is characterized by less weight, less manteinace requirements and costs, more reliability compared to a DC motor.

  4. 4. Hybrid Propulsion Experience SHOWCASE: Low emission boat for Venice Laguna LIUTO (Low Impact Urban Transport Omnibus) research project consisted of a collaborative venture between six partners from three European countries. Based on E1 vessel’s project it is defined as a Low Emission Boat (L.E.B). This hybrid propulsion vessel have been conceived in order to optimize E1 vessel’s performance. ACTV identifies its requirements for a new vessel’s performance in view of two different conditions: • in the narrow, shallow waters of the Venetian canal system; • in the open water of the lagoon or “Lido”; The aim was to develop a new model that would produce minimum wave wash, achieving optimal performance in terms of energy efficiency and manoeauvability. Moreover this solutions will provide to preserve from the wear of time the historic buildings of Venice for the next years. PPT2013.01.01.05EN 4
  5. 5. Low Emission Boat for Venice Laguna Optimizing Vessel Performance The vessel’s prototypes speed performance Venice’s water traffic legislation permits only two speed - slow in the canals and faster in open water. In order to optimize vessel’s performance our project was focused on engineering a hybrid diesel-electric system. The hybid system optimizes the boat’s performance at both speeds, permitting a switch from diesel when operating in open waters to electric propulsion in the canals. PPT2013.01.01.05EN 5

  9. 9. Hybrid Propulsion Propulsion Zero emission Mode Yacht for Ferretti Groups We have combined our expertise and our Skills with Ferretti Group, one of the world leaders in design, construction and sale of luxury motoryachts. The result of this union was the culmination of a dream, the first hybrid yacht over 20 feet long That Produces negligible tailpipe emissions. The yacht is a 75-foot tri-deck that has a a hybrid propulsion system. When running on diesel and cruising at eight knots it emits 10 kilograms of carbon dioxide for each nautical mile. The engine charges a battery pack that can also power the boat. In this diesel-electric mode, it emits less than half a kilogram each nautical mile.

  14. 14. Electric Hybrid Propulsion Batteries Workability While operating in “energy storing” mode, the batteries rapidly store the energy produced by the motorgenerator while under way. The batteries can also be recharged simply by plugging them to the shore power connection. For short range coastal cruises, the yacht can, for example, leave port, cruise around and return using only the electricity drawn and stored from the terrestrial network, providing significant energy savings and much less pollution.
