Leclanché expands its marine electrification solution to include a fast charger for ports, harbors and ships; Damen 1st adoptive


Expanding its portfolio of solutions for the marine electrification industry, Leclanché introduces a new “ports and ports” infrastructure solution allowing hybrid and fully electric vessels to recharge quickly when they return to port.

Its first customer for the turnkey solution is Damen Shipyards Group, a globally operating company with more than 50 shipyards and related facilities, which selected Leclanché to build and supply two fast-charging electric ferry stations, and support electrical storage systems on Lake Ontario in Canada. .

The agreement with Leclanché’s Stationary Solutions group provides the complete charging infrastructure. The systems will be installed next year to support two eFerries that Damen built for the Ontario Ministry of Transportation. The two electric vessels are powered by Leclanché’s Marine Rack System (MRS), certified by Bureau Veritas, under previous contracts with the Leclanché e-Marine group. (Previous article.)

  • The Amherst Islander II (Damen 6819 E3) is fully electric with a Leclanché battery system with a capacity of 1.9 MWh and produces no emissions. It will carry up to 42 cars and 300 passengers and speeds of up to twelve knots and will connect the mainland port city of Millhaven, Ontario, to Stella on Amherst Island.

  • The Wolfe islander iv (Damen 9819 E3), a larger eFerry, will provide service between Kingston on the mainland and Wolfe Island and has a 4.6 MWh Leclanché battery system. It can carry twice as many passenger vehicles (83) plus 399 passengers. It also produces zero emissions and will sail at up to twelve knots per hour, the same speed as ships powered by conventional propulsion systems.

The eFerries successfully completed their sea trials in the Black Sea at the end of April (Amherst Island II) and May (Wolfe Islander IV) respectively and are expected to be transported to Canada by a specialized semi-submersible vessel from August.

Ontario ports and port systems are equipped with a Leclanché 3.0 MWh battery energy storage system (BESS) located in port structures (one at Millhaven and one at Stella). The BESS, which will be charged by the port network, is connected to the ferry charger via 1800 kW DC-DC converters.

These “buffer stations” will be protected by the industry’s highest safety standard fire suppression system using running water along the battery racks and behind each battery module. The backs of each module have an opening allowing water spray to enter in the event of thermal events.

Crossing time between ports will be just 20 minutes and Leclanché’s high power DC-to-DC fast charging system will allow eFerries to recharge in 10 minutes in each port, well in the time it takes for the eFerries. ship to unload passengers and vehicles and reload. The batteries have been designed to charge each vessel up to 7,850 times per year or over 78,500 times over their 10-year expected life, providing 21 hours of service per day, regardless of the weather.

Our continued partnership with Damen brings several firsts to the market, including the first fully electric passenger and car ferries in North America and the first time that two of our business units have collaborated to create an end-to-end solution for a key customer. From now on, thanks to our e-Marine and Stationary Solutions teams, passengers will be able to board a ship powered by Leclanché technology on board and recharged on land – with the added benefit of our electrical storage systems ensuring the stability of the local electrical network. .
