Swiss battery manufacturer LeclanchÃ© (named for the inventor of the dry cell battery) and Finnish electric drivetrain specialist Visedo have partnered to deliver a powertrain for an electric ferryboat that will be built by Danish shipbuilder SÃ¸by Shipyard and put into service in June 2017 between the mainland and Ã†rÃ¸ Island.
The ferry will be equipped with a 4.2 MWh Li-ion battery system, making it the worldâ€™s largest ferry in terms of battery capacity, according to LeclanchÃ©. Charging power of up to 4 MW will allow the boat to be charged during short intervals in port.
CO2 emissions will be reduced by 2,000 tons per year compared with a legacy diesel ferry. Noise level and wake will also be reduced.
â€œThis project is a breakthrough in the recently introduced mobile storage business,â€ said Martti Ukkonen, Executive VP of Mobile Storage Systems at LeclanchÃ©. â€œThe novel combination of a lithium-ion battery storage system and an electric drivetrain has proven to be a true asset in the mobile system market, and not only in the marine segment.â€
LeclanchÃ© and Visedo announced a strategic cooperation in May, to develop a plug-and-play drivetrain system applicable to buses and other heavy vehicles. The first joint project will be an electric bus project for a European city. The system has been successfully tested, and the customer has committed to order a fleet of 30 to 50 electric drivetrains starting in 2016, each including 30 to 50 kWh of batteries.
