AI Technical Summary

Technical Problem

Existing acetic acid testing equipment for photovoltaic cells cannot randomly observe the corrosion of the cells, and it is difficult to maintain the acetic acid concentration and temperature normally. The driving equipment has high requirements for corrosion-resistant environment.

Method used

A device was designed that includes a main housing, an acetic acid support frame, a heating chamber, a rotating rod, temperature and humidity detectors, and a sampling box. The rotating rod drives the transmission components to realize the up-and-down movement of the battery cells, continuously supplying standard acetic acid solution and hot water/hot air. Combined with temperature and humidity detection, the observation port facilitates real-time monitoring.

Benefits of technology

It enables real-time observation of cell corrosion, maintains stability of acetic acid concentration and temperature, reduces the risk of equipment tipping over, and improves the controllability and efficiency of testing.
