STM-based vanadium redox battery management apparatus

Abstract

The invention provides an STM-based vanadium redox battery management apparatus. The vanadium redox battery management apparatus is characterized by comprising an electrolyte detection unit, a battery management main controller, a communication unit, an alarming unit and a fan unit; the electrolyte detection unit, the communication unit, the alarming unit and the fan unit are connected with the battery management main controller separately; the electrolyte detection unit comprises an electrolyte temperature detection unit; the battery management main controller adopts an STM single chip microcomputer; and a timing module and an AD converter are built in the STM single chip microcomputer. The vanadium redox battery management apparatus has the beneficial effects as follows: multiple items of parameters of electrolyte of the vanadium redox battery can be monitored in real time; and when it is monitored that a certain parameter is abnormal, an alarming signal can be given out; and particularly, when high temperature abnormity is monitored, the electrolyte can be subjected to cooling protection, and an alarm signal can be given out if the cooling measure is in failure within a predetermined time.

Description

technical field [0001] The invention relates to the field of vanadium batteries, in particular to an STM-based vanadium battery management device. Background technique [0002] Vanadium batteries have a series of unique advantages such as large power, large capacity, high efficiency, long life (charge and discharge can reach more than 100,000 times), green and environmental protection, and can be used in wind power generation, photovoltaic power generation, electric vehicle power supply, power grid peak regulation and other fields widely used. [0003] Vanadium battery (VRB) is a kind of battery that can flow, and is gradually entering the commercialization stage. As a chemical energy storage technology, VRB has many unique features in design compared with traditional lead-acid batteries and nickel-cadmium batteries, and its performance is also suitable for various industrial occasions, such as: it can replace gasoline engines, backup power etc. Vanadium batteries convert...

Problems solved by technology

[0004] The electrochemical performance of the vanadium battery system is affected by many factors, such as electrolyte temperature, concentration, flow rate, etc., especially, heat is generated during battery charging and discharging, and the battery temperature will gradually rise. If it is not monitored, it will affect the use of the battery life, and the pentavalent vanadium in the vanadium battery anode liquid is easy to precipitate vanadium pentoxide and precipitate when the temperature is higher than 45 degrees Celsius. The precipitated precipitate blocks the flow channel, covers the carbon felt fiber, and deteriorates the stack performance until the scrapped, and the electrolyte temperature of the stack can easily exceed 45 degrees Celsius during long-term operation, so when the vanadium battery is working, a rigorous vanadium battery management system is required to trigger the protection mode in time when a potential safety hazard is detected. alarm to notify staff
