An on-line discharge capacity load discharge distribution method for a battery pack
By acquiring four-dimensional operating condition data and implementing dynamic dual closed-loop control, the problems of delayed disturbance identification and single control mode in existing online capacity control technologies have been solved. This enables accurate identification and hierarchical management of disturbances, thereby improving the safety and reliability of capacity control operations and power supply.

AI Technical Summary
Existing online capacity control technology lacks comprehensive perception of system operating conditions and the ability to respond to disturbances in a graded manner. It cannot accurately distinguish the level of disturbance, which makes capacity control operations prone to malfunctions or power outages. Furthermore, it cannot achieve a dynamic balance between capacity control accuracy and power supply safety.
By collecting four-dimensional operating condition data in real time, dynamically switching the priority of dual closed-loop control and load discharge distribution strategy, including parameters on the mains side, DC bus side, load side and charger side, classifying disturbance levels and executing differentiated load regulation, a dual closed-loop control architecture and a three-level load hierarchical management system adapted to the full operating conditions of the core capacity are constructed.
It enables accurate identification and hierarchical management of disturbances, enhances the anti-disturbance capability during online capacity expansion, ensures the coordinated protection of capacity expansion operations and DC system power supply safety, and avoids bus voltage drops and core load power supply interruptions.
