Integration-based intelligent unmanned aerial vehicle starting power supply subsystem

The invention relates to an integration-based intelligent unmanned aerial vehicle starting power supply subsystem. The system can be used for starting an engine when there is no ground power supply. The system can be used for supplying power externally together with an emergency power supply whether a master power supply is ineffective. According to the system, a voltage (8V-12.6V) and a current (300A/5s) which satisfy demands can be output under a condition of 20 degrees centigrade below zero to 60 degrees centigrade. The system comprises a three-string highly integrated management system and a 12V/15Ah battery cell stack. The system can satisfy onboard real-time charging, voltage and current limiting control, discharging control, balance control, (voltage, current, temperature and capacity) detection, short-circuit protection, communication, fault diagnosis alarm and BIT self-checking functions. The system is characterized in that the highly integrated management system and the wide temperature range and high rate discharging battery cell are perfectly integrated, the function integrally designed intelligent unmanned aerial vehicle starting power supply is realized, and the light-weight, miniaturized and intelligentized application purpose is realized.
