A metal-air battery management system

Abstract

The invention discloses a metal-air battery management system, comprising: electric stack, shunt, two-position two-way solenoid valve, two-position three-way solenoid valve, pump, liquid storage tank, control component, liquid level sensor, wherein the electric stack , shunt, two-position two-way solenoid valve, two-position three-way solenoid valve, pump, and liquid storage tank are connected through pipelines to form a liquid circuit module of the metal-air battery, while the control component is electrically connected to the stack, two-position A two-way solenoid valve, a two-position three-way solenoid valve, a pump, and a liquid level sensor form a control module of the metal-air battery. This management system is very convenient to realize the electrolyte filling, cycle control, discharge, easy operation, high integration and reliability, effectively maintain the internal resistance stability and battery energy efficiency of the metal-air battery, and has a good application effect .

Description

technical field [0001] The invention relates to the technical field of metal-air batteries, and more particularly relates to a management system capable of conveniently realizing metal-air battery operation control and electrolyte supplement and replacement. Background technique [0002] A metal-air battery is a device in which metal is used as the anode, which is oxidized and dissolved during the discharge process, and the air electrode is used as the cathode. During the discharge process, oxygen in the air enters the battery from the atmosphere through the electrode and is reduced to release electrical energy. . It has the advantages of large specific energy, long life, low cost, environmental protection, safety, and convenient recycling. It has broad application prospects in many fields of mobile power supplies such as communication power supplies, field emergency power supplies, lighting power supplies, automotive power supplies, and reserve power supplies. Its research...

Problems solved by technology

[0004] In the existing technology, manual filling or external pump pressure filling is mostly used. For example, patent 201310691253.3 (a metal / air battery electrolyte management device and its application) designed an electrolytic solution integrating injection and liquid discharge functions. liquid management device, but the filling of the electrolyte is cumbersome, and the amount of filling is also difficult to control, and the circulation of the electrolyte in the battery stack cannot be realized; based on the above technical problems, professionals have also made a series of improvements, such as patent 201310254486.7 ( A metal-air battery) proposes an electrolyte circulation device for a metal-air battery, and realizes the filtration of reaction by-products by setting a sediment filter, but does not involve the filling and emptying of the electrolyte, and the integration of device functions not high
