Key aspects of a 5MWh+ energy storage system
This article discusses the key points of the 5MWh+ energy storage system. It explores the advantages and specifications of the
Designed for high-capacity energy storage, the 5 MWh Container ESS maximises space efficiency within a compact 20-foot container, significantly reducing balance of plant (BOP) costs compared to other designs. The system utilises 315 Ah LFP cells, celebrated for their high energy density and extended lifespan.
The system also features a DC voltage range of 1,081.6 V to 1,497.6 V. From ESS News China-based rolling stock manufacturer CRRC has launched a 5 MWh battery storage system that uses liquid cooling for thermal management.
The DC sides of the battery clusters are connected in parallel and then connected to the DC side of the PCS. The energy of a single cabin can reach more than 5MWh. Compared with the mainstream 20-foot 3.72MWh energy storage system, the 20-foot 5MWh energy storage system has a 35% increase in system energy.
In fact, with the release of 300Ah+ large-capacity battery cells, members of China top 10 energy storage system integrator have deployed 5MWh+ energy storage battery compartments, such as CATL, Sungrow, CRRC Zhuzhou Institute, TrinaStorage, etc.
