AI Technical Summary

Technical Problem

Sensors are susceptible to electrolyte corrosion and temperature and humidity changes in the working environment of flow batteries, which can lead to detection drift and decreased accuracy.

Method used

It adopts a mechanical structure design, utilizing the lever principle of slider, push rod and vertical rod. The movement of slider drives the rotation of vertical rod, and the pointer on the dial indicates the expansion amount in real time, thus avoiding the use of sensors.

Benefits of technology

It enables dynamic monitoring of battery expansion during the charge-discharge cycle of flow batteries, avoiding detection errors caused by environmental factors and improving detection accuracy and reliability.
