Superfast charging electric ferry from Vattenfall & Echandia Marine
Vattenfall and Echandia Marine have developed an emission and noise reducing solution for electric ferries which will also provide superfast charging and lower operational and maintenance costs. Installed on the E/S Movitz, a 98 passenger capacity electric ferry shuttle service operating in central Stockholm, the new systems can be fully charged in ten minutes.
“We are proud to be able to contribute to reducing emissions for transport also by sea through innovative and sustainable technology. The collaboration means that we can deliver value to the customer through our new functional solutions for fast charging, while at the same time providing great environmental and climate benefits for both society and residents in Stockholm,” says Torbjörn Johansson, head of Vattenfall Network Solutions in Sweden.
The solution is called "Power as a service" and means that the ownership and management of the equipment, which includes the charging station, the battery system and the driveline, lies with Vattenfall with long experience of owning and operating electric power systems. This includes, among other things, operation and maintenance, electrical safety responsibility and any further investments during the contract period.
State-of-the-art battery system
Echandia Marine operates the shipping company Green City Ferries and has now upgraded its electric passenger ferry E/S Movitz with a new battery system, "Echandia LTO", based on state-of-the-art battery technology, that among other things enables superfast charging.
“Echandia's core business is emission-free energy systems for the demanding marine market, which has been successfully demonstrated in recent years with the electric boat E/S Movitz. We have developed our own electric propulsion systems, including a new battery system based on Toshiba's new generation LTO battery modules (Lithium Titanium Oxide) that enables higher power and faster charging than before. The fast charging station in central Stockholm provides considerably higher charging power than those available for charging electric cars”, says Bilal Malla at Echandia Marine.
