The classification societies DNV and Lloyd’s Register have recertified Swiss battery manufacturer Leclanché’s Marine Rack System (MRS-2) for operation with the company’s latest 65 Ah lithium-ion pouch cells.
MRS-2 is a modular and scalable lithium-ion battery system for electric and hybrid vessels that features a range of safety measures and a proprietary battery management system complete with liquid cooling. In principle, the MRS-2 already had the certifications, but not with the new 65 Ah cell – Leclanché has listed all the certifications in the announcement linked below.
DNV’s certification upgrade was approved in late January 2022, while Lloyd’s Register type approval for the company’s 60 Ah and 65 Ah cells was granted in October 2021, according to Leclanché. The approvals provide external evaluation and certification of the system’s performance and compliance with all applicable industry safety and regulatory requirements.
Thanks to the new cell, the MRS-2 can deliver ten per cent more energy with the same footprint and weight. The system is available in four standard rack heights to accommodate different sized battery rooms. Pack voltages up to 1100 V DC are available.
“These latest certifications from DNV and Lloyd’s Register confirm the quality, performance and safety built into our Marine Rack System based on 100% in-house technology,” says Leclanché CEO Anil Srivastava. “From our initial design concept through numerous enhancements over the years, our MRS has proven itself to be a reliable and sustainable alternative to traditional ferry propulsion systems.”
