Container energy storage production line

The container complies with the ISO standard. The system is installed in 20 ft, 40 ft and containers of other sizes according to the system size, and the containers can be combined together. In this configuration, the system can be transported by trailer on land and by container carrier over water (Figure 2).

2MW energy storage system is currently in the process of being commissioned on the Orkney Islands, where wind power, wave power and tidal power plants are part of the energy supply mix and power is exported to or imported from the British mainland through 33kV submarine cables.

Example of containerized ESS and its operation Currently, the scheduled power discharge of 500kW and 1MW in the plant is conducted during a time band requested by the electric company.

A gas extinguishing equipment is installed in the container in consideration of the potential for a fire to occur, as many electric parts including the cells are installed in the container. The installation of fire extinguishing equipment in the container minimizes and optimizes the amount of extinguishing gas, and reduces the extinguishing time.

The battery rack consists of the required number of modules, the Battery Management Unit (BMU), a breaker and other components. The container consists of the required number of the battery racks, as well as air conditioning and fire extinguishing equipment.
