Abstract

The invention discloses a liquid flow battery monitoring device and a liquid flow battery monitoring and regulation system. The flow battery monitoring device includes a first friction part arranged on a peristaltic tube of the flow battery, the peristaltic tube is arranged around the rotor of the peristaltic pump of the flow battery, and when the rotor rotates, the peristaltic tube and the rotor are contacted and separated, and the peristaltic tube and the rotor are in contact and separated with the peristalsis. Contact and separation occur between the tube and the rotor, and frictional electrification occurs between the first friction part and the rotor. In the flow battery monitoring device of the present invention, with the contact and separation between the peristaltic tube and the rotor, the contact and separation between the first friction part and the rotor also occur, and the friction electrification between the first friction part and the rotor is realized. In the process of electrostatic induction, the first friction part generates charge transfer and can output electrical signals to the outside, so that real-time and zero-energy-consuming induction of the speed of the peristaltic pump can be realized, and then the working state of the flow battery can be monitored in real time. The structure is simple, Stable work, strong timeliness, high accuracy and energy saving.

Description

technical field [0001] The invention relates to the technical field of flow batteries, in particular to a flow battery monitoring device and a flow battery monitoring and control system. Background technique [0002] Flow battery is a new type of pollution-free chemical power source, which has outstanding advantages in energy efficiency, manufacturing cost and cycle life, and is currently one of the most promising electrochemical energy storage systems. How to monitor the state of charge of the flow battery and make up for the capacity loss during operation at any time is the focus of the stable work of the flow battery. [0003] At present, the working state monitoring methods of flow batteries mainly focus on the judgment of the open circuit voltage between the positive and negative electrodes and the monitoring of the electrolyte. These methods have the disadvantages of time-consuming and inconvenient operation. Contents of the invention [0004] Embodiments of the pre...
