South Korean battery company LG Energy Solution is to introduce a residential energy storage system (ESS) in the US in November.
The enblock S is stackable and modular (three, four or five battery module assemblies), and can be tailored to energy requirements. The system comes with battery control units and in three capacity levels: 10.6kWh, 14.1kWh and 17.7kWh.
The ESS is based on nickel, cobalt and manganese (NCM) batteries for high energy density.
The company said the system is compliant with the industry standard UL9540A fire safety rating. It expects demand for enblock S+ (which combines the company’s ESS system components such as enblock S and inverters) to be strong in California and other states where solar power systems are common.
In its third quarter results, LGES said it has decided to utilise its Arizona battery facility as the production hub for 46-Series cylindrical batteries in North America.
Preempting market demand for the 46-Series, the company said it modified its original plan for the facility, which was to produce 2170 cells at an annual production capacity of 27GWh. It will instead produce the 46-Series with an expanded annual capacity of 36GWh.
Expected production start date remains unchanged – late 2025.
The company also plans to boost the energy density of its high-nickel NCMA batteries. It will increase the proportion of nickel to over 90% and will seek fast-charging time of less than 15 minutes. This will be by adopting high-capacity, high-efficiency silicon anodes, it said in its trading statement.
