The intelligent remote maintenance system for the storage battery according to claim 2, further comprising step S8, the control main board (19) detecting whether the charging current is less than or equal to 0.01C 10; if yes, the operation goes to step S81, timing is started, the equalizing charge holding time is 10 minutes, when the equalizing charge holding time is more than or equal to 10 minutes, the switch CDJ and the switch WH1 are opened, the switch ZY1 is closed, and the remote charge-discharge operation is ended; if not, go to step S82;
and step S82, judging whether the average charging time is more than or equal to 10 hours, if so, opening the switch CDJ and the switch WH1 and closing the switch ZY1, ending the remote charging and discharging operation, and if not, continuing charging and re-entering the step S8.
4. The intelligent remote maintenance system for the storage battery as claimed in claim 3, wherein the switch ZY1, the switch BY1 and the switch WH1 adopt a relay or a contactor; step S41, the control main board (19) feeds back a preset failure signal to the central remote control platform (11), detects the states of the relay and the contactor, preliminarily judges a fault point, displays the fault point and then ends remote charging and discharging operation; the step S41 is connected to the step S4, and when the switch ZY1 fails to open or the switch WH1 fails to close, the step S4 proceeds to the step S41.
5. An intelligent remote maintenance system for storage batteries according to claim 4, characterized in that the control mainboard (19) feeds back the detected failure point to the central remote control platform (11).
6. The intelligent remote maintenance system for the storage battery according to claim 5, wherein a serial server (12) is further connected between the liquid crystal control terminal (13) and the central remote control platform (11), the serial server (12) is connected with the liquid crystal control terminal (13) and the central remote control platform (11), the liquid crystal control terminal (13) is in communication connection with the central remote control platform (11) through the serial server (12), and a preset command in step S2 is sent from the central remote control platform (11) and then enters the liquid crystal control terminal (13) through the serial server (12).
