Description

technical field [0001] The invention belongs to the technical field of battery management, and in particular relates to a battery management and control method, device, equipment and medium based on graph theory. Background technique [0002] With the breakthrough of energy storage battery material technology, the application of new energy has ushered in great development. The energy storage battery system is an important part of the new energy application. As the core component of the energy storage system, the battery is the main detection object and control of the entire energy storage system. Target. The main electrical performance indicators and control basis of the battery are voltage, current and residual energy. The size of the three will fluctuate with the state of charge and discharge and have a correlation. When charging, the voltage and residual energy will continue to increase throughout the process, and the voltage at a certain moment is proportional to the cu...
