  "country": "US",
  "title": "Managing Power with Different Types of Batteries in an Energy Storage System",
  "original_title": "Energy storage system and management method thereof",
  "summary": "This patent describes an energy storage system that uses multiple types of batteries, each with different charging and discharging speeds, to efficiently manage power from various sources like solar panels or the main power grid for different electricity needs.",
  "what_it_does": "This patent details an energy storage system (ESS) designed to handle varying power demands and supplies. It includes a power station (which can be renewable or non-renewable) and an external power grid. The core of the system is an energy storage facility with a Battery Management System (BMS) that controls several individual energy storage units, or 'apparatuses' (Claim 1). Crucially, these apparatuses contain different types of batteries, each with distinct charge and discharge times. For example, a 'first battery type' might be fast-acting for sudden power needs, while a 'second battery type' has longer charge/discharge times, suitable for steady, long-term power (Claim 1). The BMS can individually charge these batteries from either the power station or the grid, and discharge them to supply power to a load. The system can use the faster batteries to handle sudden 'peak loads' and the slower ones for 'base loads' (Claim 2).",
  "what_it_does_not_cover": [
    "Does not cover an energy storage system that uses only one type of battery for all storage needs.",
    "Does not cover systems where individual battery apparatuses are not controlled separately by a Battery Management System (BMS).",
    "Does not cover systems where all energy storage apparatuses have identical charging and discharging periods.",
    "Does not cover a system that only discharges batteries without the ability to charge them from an external power grid or power station.",
    "Does not cover an energy storage system that lacks a power station or an external power grid as power sources."

  "abstract": "An energy storage system includes one or more new and renewable energy power stations generating power with a new or renewable energy source, and an energy storage facility including a plurality of energy storage apparatuses to be charged by one of an external power grid supplying power to a power load and the one or more new and renewable energy power stations, and to be discharged to supply the power to the power load, wherein the plurality of energy storage apparatuses have different charging and/or discharging periods.",
