Zusammenfassung:Method and apparatus for optimized battery life cycle management are described. A battery management system (BMS), comprising a battery, identifies battery-specific factors with associated environmental conditions, and battery history profiles at a current time instant. The BMS measures current, voltage, and/or power of the battery instantaneously. The resulting battery measurements, the battery-specific factors with associated environmental conditions, and the battery history profiles, formed as battery dynamic situations at the current time instant, may be time stamped for estimating an instantaneous battery state of the battery. The time stamped battery dynamic situations may be aggregated for long-term trend analysis for the battery state. The instantaneous battery state estimate is updated by comparing with the long-term trend analysis to manage battery charging or discharging. The battery operating conditions are determined based on the updated battery state estimate. The BMS may manage system power consumptions based on the determined battery conditions.
