The invention discloses an intelligent remote maintenance system of a battery, which comprises a central remote control platform, a charging module, an intelligent load unit, a control main board, a battery parameter measuring instrument, a commercial electric state collecting instrument, a contact control box and a liquid crystal control terminal. The intelligent remote maintenance system comprises a central remote control platform, a charging module, an intelligent load unit, a control board, a battery parameter measuring instrument, a commercial electric state collecting instrument, a contact control box and a liquid crystal control terminal. A switch FZ, a switch WH1, a switch ZY1 and a switch CDJ are arrange in that contact control box; S1, the central remote control platform sends the battery pack maintenance preset command; 2, aft receiving that preset command, the liquid crystal control terminal transmit the preset command to the control motherboard, and the control motherboardanalyzes the battery pack maintenance preset command; 4, control that main board to control the switch ZY1 corresponding to the code of the switch to be open and the switch WH1 to be closed; 5, enterthat maintenance operation of the battery pack and controlling the control switch FZ of the main board to be close; 6, aft that battery pack is discharged, the switch FZ is tur off and the battery pack is stationary; 7, aft that static setting is complete, the switch CDJ is closed; The invention enables the worker to get rid of the maintenance mode of the close contact detection.
