Problems solved by technology

In order to ensure the circulation of the electrolyte, the battery pack generally adopts a cycle method in which the electrolyte enters from the bottom and exits from the top. Multiple cells are connected through the main channel, and the fluid volume in the cells is controlled by the height of the upper liquid outlet. As the number of batteries in series increases , the difference in the flow rate of each single cell per unit time is gradually obvious, and under severe working conditions (such as the on-board power supply working at an inclined position), the flow rate of the single cell at a high inclined position decreases due to the high outlet position, and in severe cases There is even no electrolyte circulation, which leads to differences in cell temperature and discharge performance. In severe cases, the cathode is damaged due to temperature out of control

Embodiment 1

[0030] Example 1, such as figure 1 , figure 2 As shown, in the horizontal working condition, the battery pack (1) is fixed in the fixed frame (6) through the movable support plate (8) of the movable connection mechanism (4) and the auxiliary limiting part (7). In the tilted condition, the battery pack (1) is tilted. At this time, the electronic level detects that the inclination angle is >5°, and the movable support plate (8) at the bottom of the battery pack (1) is moved out from the lower part of the battery pack (1) and passed through the upper part. The chains (7) of the four auxiliary limit parts are positioned and dropped to directly above the liquid storage unit, and the horizontal position of the battery pack is maintained by using the level of the liquid surface to improve the consistency of liquid injection.

Abstract

A metal-air battery system, comprising a metal / air battery pack, a liquid storage unit, a movable connection mechanism, and a fixing frame; A closed liquid storage container made of high-quality waterproof materials; the metal-air battery system of the present invention can adapt to harsh working conditions (inclination), realize the automatic horizontal placement of the battery pack, and improve the consistency of the electrolyte flow of the battery pack; high-consistency electrolysis The liquid flow effectively controls the performance of the single cell (voltage, temperature, etc.), improves the discharge capacity of the system, improves the utilization rate of the anode, and effectively prolongs the service life of the cathode under actual working conditions.

Description

technical field [0001] The invention relates to a metal / air battery system, in particular to a balance adaptive metal / air battery system. Background technique [0002] A metal / air battery is an electrochemical reaction device that uses metal (such as magnesium, aluminum, zinc, etc.) as the anode fuel, oxygen in the air as the oxidant, and lye as the electrolyte solution. my country's magnesium, aluminum, zinc and other metals are rich in reserves and low in price, so metal / air batteries have broad application prospects in many fields of mobile power sources such as communication power supplies, field emergency power supplies, lighting power supplies, and reserve power supplies. [0003] For metal / air batteries, multiple metal / air cells need to be connected in series to obtain higher output voltage; for high-power metal / air battery systems, it is often necessary to circulate the electrolyte to reduce the temperature of the battery pack. Recycled products are taken outside th...
