[0028] Based on the fault emergency processing device of the lithium-ion starting battery 30, the present invention also provides a fault emergency processing method of the lithium-ion starting battery 30. In the initial state, the emergency connection pole 43 is not connected to the first pole P- of the load, and the first pole 41 is used to power the first pole P- of the load, and the second pole 42 is used to power the second pole P+ of the load; when the battery management module 20 fails, the first pole 41 loses power, and the emergency connection unit is used to electrically connect the emergency connection pole 43 to the first pole P- of the load, so that the emergency connection pole 43 is used to power the first pole P- of the load, and the second pole 42 is used to power the second pole of the load.

[0029] Specifically, in one embodiment, the emergency connection unit is a power cord detachably connected to the emergency connection pole 43 and the first pole 41.

In the initial state, the control switch is disconnected to disconnect the power line, so that electricity is transmitted from the first pole B- of the lithium-ion starting battery 30 to the first pole 41 through the battery management module 20, and then transmitted from the first pole 41 to the first pole P- of the load through the power line. When the battery management module 20 fails, the operation unit SB is operated to turn on the control switch, and at this time, electricity is transmitted from the first pole B- of the lithium-ion starting battery 30 to the emergency connection pole 43 through the fault emergency processing unit 10 or 10a, and then transmitted from the emergency connection pole 43 to the first pole P- of the load through the power line.
