A parallel power supply system of zinc-silver reserve battery and heat battery

Abstract

The present invention provides a zinc-silver reserve battery and thermal battery parallel power supply system, comprising a housing, an electrical connector, a zinc-silver reserve battery and a thermal battery; the zinc-silver reserve battery and the thermal battery are respectively fixedly installed inside the housing; The positive and negative poles of the zinc-silver reserve battery and the heat battery are connected in parallel and electrically connected with the electrical connector located outside the housing. In the present invention, the thermal battery and the zinc-silver reserve battery are combined into one for use, and through the advantages of short activation time and high specific power of the thermal battery, the disadvantages of the zinc-silver reserve battery can be well compensated, and the long-time work is satisfied. Discharge also meets the requirements of high-power discharge in the later stage of discharge, greatly improving the working performance of the battery, and because the thermal battery structure is mostly cylindrical, the installation form is flexible, and it can be better combined with zinc-silver reserve batteries.

Description

technical field [0001] The invention belongs to the technical field of parallel power supply of power sources, in particular to a parallel power supply system of a zinc-silver reserve battery and a thermal battery. Background technique [0002] Due to the advantages of stable discharge voltage, high specific energy, long working time, safety and reliability, zinc-silver reserve batteries are widely used in the field of strategic and tactical missiles. Normally, zinc-silver reserve batteries consume a lot of capacity after long-term working and discharging, and when high-current discharge is performed at the end of discharge, the working voltage drops greatly, which cannot meet the voltage index requirements. [0003] Based on the above, the inventors found that the measures taken to solve the above difficulties are mainly to increase the battery design capacity margin, but after taking this measure, the weight and volume of the battery will increase significantly, which does...
