Germany’s Lehmann Marine has released details of a new air-cooled battery system – CUBE – to accompany its existing COBRA range. The stackable CUBE series has been designed to maximise energy density in ships’ battery spaces.
Lehmann’s experts have designed a system in which flexible stacking can optimise space. Meanwhile, the air-cooling technology ensures uniform cooling of all battery cells to extend life cycles.
Modular battery units can be freely configured in strings of up to 1,000 VDC, the company said. Installations will include an integrated Battery Management System, gas exhaust, and pre-charge functionality. The CUBE system is scalable from a few kWh to several MWh.
The lithium iron phosphate (LFP) battery cells are permanently monitored by the Battery Management System at cell, module and string levels. This arrangement, the company claims, will guarantee the highest standards of safety.
LFP battery systems do not catch fire during thermal runaway, short circuit, or mechanical damage. Like other Lehmann battery systems, the new CUBE setup therefore offers a high quality option for use at sea where safety is paramount.
