Marine batteries as energy storage and power supply for propulsion significantly reduce fuel consumption, maintenance costs and emissions. With improved capacityto-weight ratio from lithium-ion technology and growing demand for lower emissions, batteries have become an ever-increasingly attractive option for the large-scale supply of energy in the maritime sector. COBRA is an advanced battery system employing inherent safe and environmentally friendly lithium iron phosphate cell technology and taking the special requirements of maritime operation and classification into account. Any scale of power storage is available by freely configuring modular units in standardised racks of up to 1,000 V DC. They include integrated Battery Management System (BMS), gas exhaust and air or water cooling for safe and reliable operation. The Compact Battery Racks are being assembled and tested in their own built production facility near the city of Hamburg.

COBRA provides a robust and reliable modular battery design with a superior energy density. A Battery Cluster with up to 16 Battery Racks and 1 Control Cabinet provides a capacity of 1.5 MWh at a length of 8.4 meters and a depth of 0.68 meters. The COBRA system is freely scalable from a few kWh to several MWh by adding as many Battery Racks or Clusters as required. High-quality and inherent safe LFP battery cells and a permanent monitoring by Battery Management System on cell, module and on rack level guarantees the highest standards for safety. LFP battery chemistry does not catch fire during thermal runaway, short-circuit or mechanical damage which makes the COBRA system the safest solution for the use at sea where safety is essential.
Inherently safe LFP technology
COBRA provides a robust and reliable modular battery design with battery racks of up to 94 kWh and 1,000 V DC. A battery cluster with up to 16 battery racks and 1 control cabinet provides a capacity of 1.5 MWh at a length of 8.4 meters. That makes COBRA a very compact battery system. The COBRA system is freely scalable from a few kWh to several MWh by adding as many battery racks or clusters as required.
High-quality and inherently safe LFP battery cells do not catch fire in case of thermal runaway, overcharge, short-circuit or mechanical damage. Combined with permanent monitoring by its battery management system (BMS) on cell, module and rack levels, COBRA guarantees the highest standards for safety with no propagation from cell to cell.
Furthermore, lithium iron phosphate (LFP) is the only chemistry used in Li-Ion batteries that occurs in its chemical composition as a natural mineral. Compared to others, such as NMC or NCA, LFP comes without the heavy-metal cobalt, making our COBRA System an environmentally friendly and green battery solution.Nuovo paragrafo
