CUBE 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 strings of up to 1,000 VDC. They include integrated Battery Management System (BMS), gas
exhaust, pre-charge functionality and a sophisticated air cooling technology for safe and reliable operation.
The Battery CUBES are being assembled and tested in Lehmann Marine´s production facility near the city of Hamburg.
CUBE PROPERTIES
• Flexible stacking for maximum utilization of
the battery room
• 1 to 11 Battery CUBES per Battery String
• Up to 137,5 kWh and 1,000 VDC per Battery String
• Battery Cluster with up to 16 Battery Strings and 2.2 MWh
• Innovative air-cooling technology ensures
uniform cooling of all cells for highest cycle life
• No propagation in case of thermal runaway on
cell level and fulfilling of highest safety requirements
• Environmentally friendly LFP battery without
cobalt and nickel
• Flexible Interface to Power Management System
(CanBus, ModBus or others)
• Including Pre-Charge functionality
CUBE provides a modular battery design with superior
energy density. A Battery Cluster with up to 16 Battery
Racks 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 a permanent monitoring
by Battery Management System on cell, module and on
string 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 CUBE system a high-quality solution for the use at sea
where safety is essential.
