1000 V battery system COBRA

iron phosphatelithiumwith integrated battery management system

COBRA is an advanced and DNV type approved battery system employing inherently safe lithium iron phosphate (LFP) 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 including efficient water or air-cooling and a battery management system. The COBRA Battery System from Lehmann Marine is type approved by DNV and complies with the European Standard of Technical Requirements for Inland Navigation Vessels (ESTRIN). 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 the most compact battery system on the maritime market. 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.
