Differentiated Technology and Performance

LG Chem's ESS battery applies the Lamination & Stacking technology to create high energy density and achieved compactness. It maintains stable structure against frequent charging/discharging, with superior lifespan compared to its competitors.

Battery Management System(BMS) with High Reliability

ESS battery requires BMS with level is divided into Module BMS, Rack BMS, and Bank BMS according to its application. LG Chem successfully developed a BMS based on its proprietary technology and has achieved the highest level of safety through an integrated management from battery cells to its entire system.

Functions of BMS (Battery Management System)

Measurement : Measure voltage, current, and temperature, which are the battery state information. - Diagnosis : Diagnose the safety and abnormal symptoms of a battery. - Control : Control temperature and cell balancing of a battery. - Communication : Provide the battery data by communicating with power conversion system as well as operating system.
