Storage battery monomer fault tolerance operation method and device

The invention discloses a storage battery monomer fault tolerance operation method and device. The method comprises the following steps: acquiring voltage and temperature of a storage battery monomer and voltage and current data at two ends of a storage battery pack in real time; analyzing a fault monomer position and a fault type through the voltage and temperature of the storage battery monomer and the voltage and current data at the two ends of the storage battery pack; and determining a corresponding fault-tolerant operation strategy based on the fault monomer position and the fault type. According to the method, individual monitoring data and overall monitoring data are obtained by monitoring the storage battery monomers and the storage battery pack respectively, then the positions and types of fault monomers are accurately analyzed, meanwhile, different fault-tolerant operation strategies are adopted based on different fault occurrence conditions, and the power supply reliability of the direct current s
