When it comes to providing sufficient power on board ships the factor space can be a tough nut to crack. A flexible stacking of battery modules can make a difference and provide the most energy density in the battery room. For that, we developed a battery system with a superior energy density that can be stacked very flexibly for optimum use of space. CUBE is a modular system of very compact design and incorporates an innovative air-cooling technology that ensures uniform cooling of all cells for the highest cycle life. Scalable and safe flexibitliy CUBE provides a modular battery design with superior energy density. Any scale of power storage is 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. A battery cluster with up to 16 battery strings and 1 control cabinet provides a capacity of 2.2 MWh. The CUBE system is scalable from a few kWh to several MWh and allows for optimal use of battery room space. LFP battery cells and permanent monitoring by the Battery Management System on cell, module and on string levels guarantees the highest standards for safety. LFP battery chemistry does not catch fire during thermal runaway, short-circuit or mechanical damage which makes the CUBE system a high-quality solution for the use at sea where safety is essential.
