US Patent 11968061 Power management system having gateway engine and driving method thereof

The disclosure relates to a power management system having a gateway engine for automatic mapping and cloud interoperability of ESS facility data and a driving method for the system. The power management system includes an interface unit forming a communication protocol with at least one or more storage devices; and a gateway engine including a data receiving unit receiving registration data from at least one energy storage device through at least one communication protocol included in the interface unit, a data mapping unit identifying an energy storage device based on registration data received by the data receiving unit, and a cloud interoperating unit linking registration data mapped by the data mapping unit to a cloud environment, automatically maps data, applies a control logic, and interoperates with a cloud EMS, thereby reducing man-hours for developing a PMS/EMS, securing profitability, and expanding the small-scale ESS market.
