Virtual battery cell system, operation method thereof and twin battery

The invention discloses a virtual battery cell system and an operation method thereof and a twin battery. The virtual battery cell system comprises an upper computer, a control unit and an execution unit; a data driving battery model is built in the upper computer; the data driving battery model is obtained by inputting charging and discharging operation data of a physical battery cell into a neural network model for training; the upper computer is connected with the control unit so as to send simulation parameters output by the data driving battery model to the control unit; the control unit drives the simulation parameters of the battery model according to the received data to judge the charging and discharging state so as to generate a charging and discharging control command, and the control unit is connected with the execution unit so as to send the charging and discharging control command to the execution unit; and the execution unit outputs charging and discharging characteristics according to the rece
