Norwegian approval for lithium-ion energy storage

The storage system has been granted approval for use in a variety of hybrid and fully electric propulsion applications.

“The NMA approval is a major step for Saft Marine systems, it is a key recognition of our Li-ion Super-Phosphate (SLFP) chemistry, which offers a very high level of safety” said Didier Jouffroy, marine product manager.

He added that Saft’s marine battery technology has been adopted by some of the world’s most innovative and prestigious vessels for applications where environmental performance, safety and cost efficiency are essential.

The approval process was based on simulated thermal runaway tests carried out on the Seanergy systems by an independent laboratory in August 2016. During the propagation test 1, a cell was forced into a thermal runaway situation by a specific device inserted inside the cell.

This test was performed three times and the batteries passed the test on each occasion with no uncontrolled event, no fire and no explosion, with nearby cells remaining in a safe condition and no propagation to neighboring modules.

Saft is the only manufacturer of marine lithium-ion (Li-ion) batteries to use the Li-ion Super-Phosphate (SLFP) chemistry.
