The fuel cell stack consists of hundreds of single-chip fuel cells. The detection of each battery voltage is the basis for maintaining stable operation of the battery stack. A single fuel cell detection based on battery monitoring chip LTC6803 and PIC microcontroller is designed. The system adopts a stacked structure to realize multi-chip LTC6803 chip cascading to realize voltage detection of the series battery pack which designs hardware circuit and software program and practice proves that the system realizes high-precision detection of the fuel cell stack cell voltage.
