Description

Technical Field

[0001] The utility model belongs to the technical field of power supply, and in particular relates to a maintenance-free emergency power supply. Background Art

[0002] Most of the existing emergency power supplies use lithium-ion batteries as energy storage units. However, lithium-ion batteries have self-discharge reactions and poor monomer consistency, which requires regular maintenance when used as emergency power supply systems to ensure that they can be used normally in critical moments. At the same time, lithium-ion batteries are dangerous and may cause battery heat loss and combustion if they are not properly operated during use.

[0003] At the same time, when the application scenario is shipborne, the working environment of the power supply is humid, so the power supply needs to have a high waterproof level and must also have the ability to resist mildew and salt spray. Under the premise of long-term storage, the current emergency power supply technology basically cannot meet the requirements.

[0004] The patent document with publication number CN108172856A discloses a novel combined battery with the comprehensive performance of a zinc-silver reserve battery and a thermal battery, comprising: a zinc-silver reserve battery, a thermal battery and a combined battery shell; the zinc-silver reserve battery comprises a zinc-silver reserve battery liquid reservoir, a zinc-silver reserve battery combined electrode group and a zinc-silver reserve battery heater; the zinc-silver reserve battery heater is located at the bottom of the hollow cavity of the combined battery shell; the zinc-silver reserve battery combined electrode group is located above the zinc-silver reserve battery heater, the zinc-silver reserve battery liquid reservoir and a gas generator are located above the zinc-silver reserve battery combined electrode group, the thermal battery is located above the zinc-silver reserve battery liquid reservoir, and the thermal battery is fixedly connected to the zinc-silver reserve battery liquid reservoir and the zinc-silver reserve battery heater; a combined battery socket is installed on the outer wall of the combined battery shell, and the combined battery socket is electrically connected to the zinc-silver reserve battery heater, the gas generator and the thermal battery respectively. However, the zinc-silver storage battery and the thermal battery in the combined battery are arranged in the same cavity, and the heat generated will cause the two batteries to affect each other; and no exhaust structure is provided, which is not conducive to the discharge of excess gas generated by the zinc-silver storage battery.

[0016] The beneficial effects of the utility model are:

[0017] The utility model adopts a power supply form in which the zinc-silver reserve battery needs an external activation power supply according to its characteristics, and a zipper mechanism is used to activate the thermal battery, which then activates the gas emitter of the zinc-silver reserve battery to complete the liquid injection process of the zinc-silver reserve battery, and finally the zinc-silver reserve battery emergency system supplies power. The reliability and safety of the zinc-silver reserve battery and the thermal battery are both better than those of lithium batteries, and both batteries can be stored for a long time of not less than 10 years without the need for regular maintenance.

[0018] Both the zinc-silver reserve battery and the thermal battery have their own sealed housings, which can ensure that the emergency power supply can be stored for a long time in a shipboard environment. The zinc-silver reserve battery and the thermal battery are placed in two different cavities to prevent heat transfer between them and to prevent corrosion to the thermal battery when a small amount of electrolyte leaks from the zinc-silver reserve battery.
