Lehmann Marine, a Germany-based lithium iron phosphate (LFP) battery systems specialist, has received type approval from the UK classification society Lloyd’s Register for its CUBE battery system.

According to Lehmann, CUBE provides a modular LFP battery design with “superior” energy density. Any power storage scale is said to be available by freely configuring modular units in strings of up to 1,000 VDC. They include an integrated battery management system (BMS), gas exhaust and pre-charge functionality, the company said, claiming that the battery system “excels with a superior energy density,” being able by design to be stacked flexibly for optimum use of space. CUBE’s air-cooling technology, reportedly, ensures uniform cooling of all cells for the highest cycle life.
