Interface project for modular energy storage

Energy storage system provider Commeo has teamed up with Harting to develop interfaces for modular energy storage systems in applications ranging from mobile robots to the power supply for industrial plants and factories.

Modular energy storage can be used as an emergency power supply or as a mains buffer to provide compensating power when required. The solution consists of integrating modules from the Han-Modular series and the Han Docking Frame into one unit.

The interface for supplying power and data can be quickly placed into the energy storage blocks, whilst the housing for the modules is recessed in the block interior with the mating side protruding centrally from the back of the block. The Commeo system consists of energy storage blocks that are over 20cm wide, containing multiple layers of lithium-ion cells. The blocks are responsive via a bus system and are aggregated into industrial storage cabinets.

Each modular energy storage block has its own battery management system (BMS). On the top floor of each storage cabinet is the Commeo control unit ccuHV. The two-metre high standard version of the cabinet offers space for 48 blocks. The local control unit communicates via CAN bus with each individual block and the downstream control components.

The layout of the storage block cabinets consisting of 1.5 kWh modules (in 48 V systems) permits the exact battery capacity to be reproduced or replaced as needed. The risk of over-dimensioning or under-dimensioning does not exist, as the efficiency of the system can be corrected afterwards so the system can easily scale from a few KWh to more than 1MWh.
