Description

Technical Field

[0001] The invention relates to the technical field of zinc-silver reserve batteries, and in particular to a multi-mode output zinc-silver reserve battery group structure. Background Art

[0002] Zinc-silver reserve battery packs are power sources in the aerospace field. The special application areas directly require the batteries to have the characteristics of high output voltage accuracy, small size, and diverse working modes.

[0003] Most of the existing traditional zinc-silver reserve battery packs are used in a one-to-one output mode, and it is impossible to provide different output mode power through a group of batteries. The battery usage in this mode is single and relatively large in size. If multiple groups of equipment use electricity at the same time, the system provides relatively more application guarantees. For example, the system provides multiple groups of activation voltages and heating voltages; multiple battery stacks and liquid storage tanks need to be designed inside the battery. Summary of the invention

[0004] The main purpose of the present invention is to propose a multi-mode output zinc-silver reserve battery pack structure, aiming to solve the above technical problems.

[0008] a gas generator, the gas generator being disposed on the liquid reservoir;

[0009] All the single cells inside the housing are connected in series and tapped to form multiple power supply modules that independently supply power to the outside.

[0010] Alternatively, all the single battery cells inside the housing are divided into multiple groups, and each group of battery cells is connected in series to form an independent power supply module that supplies power to the outside independently.

[0011] Preferably, the width of each single battery slot on the housing is the same, and the diameter of each corresponding liquid inlet hole is the same. Specifically, the width of each single battery slot on the housing is 6mm, and the diameter of the liquid inlet hole corresponding to each single battery slot is φ1.2mm.

[0012] Optionally, the single battery slots on the shell have different width specifications, and the liquid inlet diameters corresponding to the single battery slots of different width specifications are different. Specifically, the single battery slots on the shell have two width specifications, 12mm and 8.3mm respectively; the liquid inlet diameter corresponding to the single battery slot with a width of 12mm is φ2mm; the liquid inlet diameter corresponding to the single battery slot with a width of 8.3mm is φ1.4mm. Alternatively, the single battery slots have two width specifications of 16mm and 12mm; the liquid inlet diameter corresponding to the single battery slot with a width of 16mm is φ2mm; the liquid inlet diameter corresponding to the single battery slot with a width of 12mm is φ1.2mm.

[0013] Preferably, an exhaust device is provided on the shell, and the exhaust device is connected to the liquid separation tank. When the zinc-silver reserve battery pack is activated, the excess gas inside the shell is discharged to the outside of the battery stack through the exhaust device.

[0014] Preferably, a first sealing joint is provided between the liquid reservoir and the liquid separation tank, and a second sealing joint is provided between the gas generator and the liquid reservoir; sealing membranes are provided in the first sealing joint and the second sealing joint, respectively; when the zinc-silver reserve battery pack is not activated, the electrolyte is sealed and stored in the liquid reservoir through the first sealing joint and the second sealing joint; when the zinc-silver reserve battery pack is activated, the high-pressure gas breaks through the sealing membrane.

[0015] Preferably, all the single cells inside the shell are connected in series and then tapped to form two power supply modules to independently supply power to the outside.

[0016] Optionally, all the single battery cells inside the shell are divided into two groups, and each group of battery cells is connected in series to form an independent power supply module to supply power to the outside independently.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] (1) The zinc-silver reserve battery pack provided by the present invention adopts the same battery stack, the same activation system, and different liquid inlet systems, which can achieve uniform distribution of electrolyte and simultaneous output of different power of the array, so that one battery can meet the different power consumption and different working time of multiple groups of electrical equipment and simultaneously output, thus meeting the requirement of small battery size.
