Power cabinet management method and apparatus, and battery management system

A power cabinet management apparatus, comprising:

• a first detecting module, configured to automatically detect and store a running state of each battery power cabinet in a battery power cabinet array in real time, and the first detecting module is further configured to analyze the running state detected in real time, and acquire information of a faulty battery power cabinet;
• a cabinet exiting module, configured to allow a detected faulty battery power cabinet to exit from the battery power cabinet array according to the acquired information of the faulty battery power cabinet;
• an excluding module, configured to exclude parameters of the faulty battery power cabinet from parameter calculation of the battery power cabinet array;
• a second detecting module, configured to automatically detect state of the faulty battery power cabinet in real time;
• a cabinet adding module, configured to, when the second detecting module detected and analyzed that the state of the faulty battery power cabinet returns to normal, add the battery power cabinet that returns to normal to the battery power cabinet array;
• and
• an adding module, configured to add the parameters of the battery power cabinet that returns to normal to the parameter calculation of the battery power cabinet array;
• wherein the excluding module is further configured to request a power conversion system (PCS) to stop charging and discharging, and to disconnect high voltage of all sub-cabinets;
• request the PCS to output high voltage to battery power cabinets except the faulty battery power cabinet identified;
• and send a request to the PCS to restore charging and discharging of the battery power cabinets except the faulty battery power cabinet identified.

A battery management system, comprising:

• a processor;
• and
• a memory for storing a processor-executable instruction;
• wherein the processor is configured to:
• automatically detect and store each battery power cabinet in a battery power cabinet array in real time;
• analyze the running state detected in real time, and acquire information of a faulty battery power cabinet;
• allow a detected faulty battery power cabinet to exit from the battery power cabinet array according to the acquired information of the faulty battery power cabinet;
• and
• exclude parameters of the faulty battery power cabinet from parameter calculation of the battery power cabinet array;
• wherein the processor is further configured to:
• automatically detect whether state of the faulty battery power cabinet in real time returns to normal;
• when detected and analyzed that the state of the faulty battery power cabinet returns to normal, add the battery power cabinet that returns to normal to the battery power cabinet array;
• and
• add the parameters of the battery power cabinet that returns to normal to the parameter calculation of the battery power cabinet array;
• wherein the processor is further configured to request a power conversion system (PCS) to stop charging and discharging, and to disconnect high voltage of all sub-cabinets;
• request the PCS to output high voltage to battery power cabinets except the faulty battery power cabinet identified;
• and send a request to the PCS to restore charging and discharging of the battery power cabinets except the faulty battery power cabinet identified.
