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.
However, a small number of units, such as Sungrow, have adopted a single-side door opening design to further increase the energy density of the energy storage system. According to industry experts, most of the 5MWh+ battery cabins adopt centralized topology and liquid cooling and heat management. There are 12 battery clusters in the whole cabin.
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.
5MWh+ energy storage equipment leads to the design of long modules and large packs. The larger packs pose greater challenges to the pack’s structural strength, heat dissipation temperature distribution, and safety design.
