This invention discloses an energy collaborative management method for a containerized battery integrated system, relating to the field of containerized energy storage equipment technology. This method uses a sensor array deployed inside the battery compartment, combined with the equivalent heat capacity Ct calibrated at the factory, to acquire raw data during battery compartment operation. After data processing, energy datasets and thermal state datasets are formed. Based on the energy datasets, an effective energy transfer index Pli and a transfer matrix Pli(K,L) are constructed for energy migration state assessment. When the energy migration flow meets the standard, a thermal response energy index Qth is calculated based on the thermal state dataset for thermal accumulation state assessment. If a thermal accumulation trend exists, an energy flow collaborative decision index Efw is constructed for collaborative decision assessment. The analysis results are written into a time-series database for archiving, and data drift is judged by the periodic differential rate of change, automatically triggering a parameter self-correction mechanism. This method achieves dynamic coordinated control of energy transfer and heat load between battery compartments.
