Samsung SDI showcased the latest ESS technologies at ees Europe 2019, which was held in Munich from Wednesday to Friday.
ESS is a system that stores energy. It consists of racks, which are battery modules connected in series. Battery modules are consisting of cells. ESS manufacturers provide various type of products, from cells, modules to racks, in accordance with customer requirements.
The company exhibited its new ESS product E3, an ESS model with energy density enhanced by 20% compared to the previous model. High energy density can achieve space-efficiency because it enables even small-sized ESS to contain a large amount of energy. E3's enhanced energy density is made possible by high energy density cell technology. Samsung SDI improved E3's energy density through the changes of internal materials without changing the size of embedded battery cells. The design of the rack and module were also optimized to enhance energy density further while maintaining product size. Designed for utility and commercial, the model can be used to supplement uneven energy production of some renewable energy such as solar and wind power or to store cheap, off-peak electricity for peak hours at commercial ESS facilities.
On top of that, Samsung SDI's full ESS product lineup included 100Ah cells for ESS and high voltage ESS modules for home.
Samsung SDI also attracted attention with its further improved safety design technology. The company demonstrated its safety design capability by meeting the industry's first ESS fire-resistance test standard from Underwriters Laboratories (UL), a global safety certification company.
According to the data by SNE Research, a market researcher, the global ESS market is expected to grow by 31 percent per year, from 11.8 gigawatt hours last year to 77.6 gigawatt hours in 2025.
