BATTERY MANAGEMENT SYSTEM HAVING A PLURALITY OF BACKUP COMMUNICATION MAIN UNITS, AND AIRCRAFT

A battery management system having a plurality of backup communication main units, and an aircraft are provided. In the battery management system, a plurality of independent power battery assemblies are provided, and the design of using a plurality of backup communication main units is used; and considering the hardware failure probability and the redundancy margin, some of all battery management units are selected as backup communication main units, thereby improving the fault tolerance rate and reliability of aircraft communication, ensuring that the aircraft reliably acquires battery data required by safe flight, improving the reliability of aircraft power supply management, and guaranteeing the flight safety of the aircraft.
