A battery system based on lithium titanate oxide (LTO) technology from Sweden’s Echandia has received type-approval by Bureau Veritas
“Echandia is the only company in the world to have a certified LTO battery system for marine use in tugboats,” said Echandia founder and chief executive Magnus Eriksson. “It is a breakthrough for safe LTO technology and as tugboats and ferries in local traffic increasingly become battery-powered, the future looks very bright,” he continued.
Commercial workboats and passenger ferries require quick charging capability and are usually in operation for long periods without interruption. Echandia said the energy storage systems will be scalable, air-cooled and modular battery systems based on Toshiba’s LTO cells.
The first to use the battery system was Damen Shipyards, incorporating the technology in a new fully electric shiphandling tug Sparky for New Zealand’s largest container and international trade terminal at the Ports of Auckland. The tug was launched in 2020 at Damen’s Song Cam Shipyard in Vietnam.
Additionally, Echandia has scored several successes in the ferry market, including supplying its E-LTO battery systems for a fleet of all-electric waterbuses and ferries for Rotterdam, 23 electric water taxis for the city of Kochi in India, and a fleet of 80-passenger, electric commuter ferries operating in Copenhagen.
“This is an important milestone for the new, stable, secure LTO battery technology,” said Echandia project engineer Jacob Zeidler. “Certification for marine battery use is the most difficult to achieve, which is why LTO technology can now be expected to make an impact in several areas. Echandia already has a type-approval for its E-LTO system from DNV,” he said.
