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...

Examples

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.
