Unlocking the smart grid era by providing various ESS battery products

ESS Battery

Core Competitiveness

Through our world-renowned excellence in technology and mass production capability, we are leading the ESS market with a wide range of clients
who apply our products to power grids, UPS, and commercial and residential uses.

We maximize customer convenience by developing high-energy and high-output products for power grids and diversified household products that
reflect customer needs in each region.

Produced with first-rate battery cell technology

By applying advanced process know-how of lamination and stacking, a proprietary technology, we produce high-capacity battery cells with a uniform energy output, long battery life, and stable structure.

Providing product lines and total solution for customer convenience

Our product lines mainly consist of battery cells, packs, and racks, and we also offer optimized solutions, such as racks for power grids and residential use, according to customer needs.

Improved spatial efficiency through compact size

By applying high-capacity and ultra-slim polymer battery cells to develop grid and residential ESS, we produce slim products that maximize space utilization and require minimal installation area.

Concept of ESS

In general, energy is difficult to store and is lost after being used. Energy Storage Systems (ESS) are systems that store and manage energy so it can be used more efficiently.
ESS has applications in power plants, power transmission and distribution facilities, homes, factories, and businesses. Through a system that coupled it with renewable energy, ESS can increase the efficiency of renewable energy and reduce electricity costs. It can be also used as backup power to minimize damages from power outages.

For example, solar modules mainly installed on the roof of homes and ESS for uninterruptible power supply (UPS) in data centers store the remaining power and use it during times of high demand or when electricity prices are high. In turn, it minimizes damages from blackouts and saves electricity bills. Also, power plants can store and manage irregularly produced renewable energy, such as solar, wind, and hydroelectric power, which increases the efficiency of their use.

Application

Home Battery

When used in conjunction with solar panel installations at home, ESS stores electricity produced by solar panels during daytime to be used at nighttime.

Home battery is the optimal solution that can serve as an alternative energy source to reduce electricity costs and prepare for power outages. Installing ESS and solar power system together generates power independently, increasing the self-consumption of power at home and reducing the overall electricity cost. LG Energy Solution provides optimized products for home use under the brand "RESU."

ESS for power grids is installed at thermal power plants, solar and wind power plants, and substations. It has various applications in reducing power load, coupling with renewable power generation, and adjusting power frequency. Commercial ESS is installed in commercial buildings such as offices, schools, and factories, and is used to reduce power load or to couple with renewable power generation.
