Embodiment approach

[0072] According to a preferred embodiment of the present invention, the fixing device further includes a positioning plate, which is arranged on one side of the pole plate 2 formed by assembling various pole plate parts to fix each pole plate part; and the positioning plate is provided with The through hole corresponding to the measurement port 20 . The positioning plate can keep the assembled electrode plate 2 from being deformed, and the positioning plate is provided with a through hole corresponding to the measurement port 20 , which will not affect the insertion of the measurement probe 23 and is easy to assemble. Preferably, the positioning plate can be selected from materials with good electrical conductivity, such as copper, stainless steel, etc., so that after assembling different plates 2 into a battery, good electrical conductivity can be achieved between the adjacent positive and negative plates, so that all The measured relevant parameters can be closer to the act...

Abstract

The invention discloses a flow battery stack with a monitoring system. The flow battery stack with a monitoring system comprises: a battery stack device and a monitoring device. The battery stack device includes electrode plates provided with measuring openings; the monitoring device consists of measuring probes, which extend into the battery stack device and are arranged corresponding to the measuring openings on the electrode plates, and the monitoring device is used for monitoring the liquid flow pressure and temperature at the measuring openings. According to the technical scheme of the invention, the monitoring device is introduced into the flow battery stack, and by means of the monitoring device, actual values of relevant parameters about the interior of the battery stack and their distribution state can be directly obtained, thus providing reliable basis for optimizing the system performance of the flow battery stack.

Description

technical field [0001] The invention relates to the field of liquid flow energy storage batteries, in particular to a liquid flow battery stack with a monitoring system. Background technique [0002] All-vanadium redox flow battery is referred to as vanadium battery. It is a kind of redox flow battery. It has the advantages of long service life, energy conversion efficiency, high safety and environmental friendliness. The large-scale energy storage system is one of the main choices for grid shaving and valley filling and load balancing. [0003] Vanadium battery is mainly composed of three parts: electrode material, battery separator and electrolyte. The electrolyte is the core of vanadium battery. It is a multivalent system of vanadium, which realizes the energy storage and release of vanadium battery. The vanadium battery uses vanadium ion solutions of different valences as the positive and negative active materials respectively, and the electrolyte storage tank and the b...
