the air suction inlet of the air suction system is communicated with the battery chamber through one or more of a pipeline, a container and a valve; the pipeline, the container and the valve are communicated with the grid chamber of the liquid dispenser.

7. The apparatus for charging a battery of claim 6, wherein the bleed air inlet of the bleed air system communicates with the battery compartment through the separator compartment;

or/and the air suction inlet of the air suction system is communicated with the liquid inlet of the liquid separator;

or/and the air suction inlet of the air suction system is communicated with the battery chamber through a container communicated between the liquid outlet of the liquid separator and the battery chamber;

or/and the air suction inlet of the air suction system is connected with an air outlet arranged on the dispenser, and the distance between the air outlet of the dispenser and the liquid outlet of the dispenser is greater than 1/4 of the height of the cell;

or/and the gas outlet of the liquid separator and the liquid inlet of the liquid separator share the same opening.

8. The apparatus for charging a battery of claim 1, further comprising a flip device for effecting or/and assisting flip of the flip dispenser;

the turnover device comprises a rotating shaft which is fixedly connected with more than 2 cells at the same time, and when the rotating shaft rotates along the axle center, the rotating shaft drives more than 2 cells to rotate around the axle center at the same time.

9. The device for adding liquid to a storage battery according to claim 1, wherein the liquid adding device further comprises one or more of a liquid weighing unit and a liquid storage unit;

the liquid weighing unit is used for weighing and measuring a certain amount of liquid and can convey the weighed liquid to the liquid separator; the liquid outlet of the liquid weighing unit is communicated with the liquid inlet of the liquid distributor;

the liquid storage unit is used for storing liquid, and a liquid outlet of the liquid storage unit is communicated with a liquid inlet of the liquid weighing unit or the liquid distributor.

10. The device for adding liquid to the storage battery according to claim 9, further comprising a liquid return pipeline, wherein a liquid outlet end of the liquid return pipeline is communicated with the liquid storage unit, and a liquid inlet end of the liquid return pipeline is communicated with the liquid weighing unit and the liquid separator; the communication is combined with the valve, and the liquid in the liquid weighing unit and the liquid separator is controlled to flow back to the liquid storage unit through the valve.
