Automatic activation device for reserve battery

Abstract

The invention discloses an automatic activation device for a reserve battery. The automatic activation device comprises a battery pack and a liquid reservoir arranged above the battery pack, wherein a common gas chamber is communicated between the battery pack and the liquid reservoir; cavities are arranged in the liquid reservoir, the cavities are internally filled with electrolyte, liquid outlet holes are formed in the cavities, and valves are respectively connected with the liquid outlet holes; outlet ends of the valves are communicated with the battery pack, and inlet ends of the valves are communicated with a high-pressure gas source by a pipeline. According to the automatic activation device, each single battery corresponds to one valve and is separately provided with an electrolyte flow channel, so that the uniform distribution of the electrolyte can be realized, the phenomenon of electric leakage of a common flow channel is avoided, and the mass specific energy of the battery is improved.

Description

technical field [0001] The invention belongs to the technical field of silver series primary batteries, and in particular relates to an automatic activation device for reserve batteries. Background technique [0002] Reserve zinc-silver batteries have very high mass-specific energy, volume-specific energy output characteristics and high-rate discharge capabilities, and are widely used in avionics and missiles. After the automatic activation device receives the electrical signal, it can quickly inject the electrolyte into the battery body to provide effective electrical energy for weapons or other equipment that are in the ready state for a long time. [0003] The automatic activation device of the storage battery mostly uses the high-pressure gas generated by the gas generator to directly push the electrolyte into the common flow channel of the battery body, and then distributes it to each monomer with the high-pressure gas. This type of device is likely to cause uneven dist...

AI Technical Summary

Problems solved by technology

[0003] The automatic activation device of the storage battery mostly uses the high-pressure gas generated by the gas generator to directly push the electrolyte into the common flow channel of the battery body, and then distributes it to each monomer with the high-pressure gas. This type of device is likely to cause uneven distribution of electrolyte among the monomers , residual electrolyte in the public flow channel and leakage of electricity, etc., resulting in a decline in the overall performance of the battery pack

In addition, this type of device often fills the liquid reservoir with an excessive amount of electrolyte, which reduces the mass specific energy of the battery.
