The invention discloses a liquid injection system for a reserve battery, which comprises a battery case, a liquid storage tank, a liquid injection valve, a gas generator and an exhaust valve. The battery case is provided with a cavity of the battery case and several battery cells. The body and the public flow channel and public air channel connected with the gas generator, the cavity of the battery case and the battery cell and the public flow channel are respectively provided with a cavity liquid injection hole and a battery cell liquid injection hole. The aperture of the liquid hole is smaller than the aperture of the liquid injection hole of the battery cell. The cavity of the battery case and the battery cell and the public air passage are respectively provided with a cavity exhaust hole and an exhaust pipe. The liquid storage tank includes a liquid outlet and an inlet. The gas port, the liquid injection valve includes the liquid injection valve inlet connected with the liquid outlet and the liquid injection valve outlet connected with the common flow channel, and the exhaust valve includes the exhaust valve gas outlet connected with the air inlet and connected with the public flow channel. The air channel is connected to the air inlet of the exhaust valve; the invention injects liquid evenly, there is no electrolyte residue in the common flow channel, and no leakage current is generated when the battery is discharged.
Description
technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a liquid injection system for a reserve battery, which is suitable for a reserve zinc-silver oxide battery that requires high liquid injection uniformity and low leakage current requirements. Background technique [0002] Due to the advantages of high specific energy, high specific power, high rate discharge and stable voltage, the reserve zinc silver oxide battery has been widely used in many occasions, especially in the field of aerospace technology, it is still the preferred power supply. [0003] Due to the special application, not only the electrical performance of the battery needs to be fully utilized, but also its automatic liquid injection system must also meet the requirements of reliability, compact structure, light weight, uniform distribution and rapid activation, which has become a technical difficulty in the development of this type of battery.
