Acuity’s Custom Solution For Battery Expansion Laser Displacement Test

 

December 2022, MARIETTA, GA ~ A US manufacturer was looking to find a system to precisely measure the displacement of a battery cell during a battery expansion measurement test. This customer was looking to measure the battery cell expansion under cycling and other pressures in a controlled temperature environment to use the results and method to guide the battery cells design. The manufacturer was looking to use non-contact measurement to precisely monitor the displacement without the drawbacks of touching the material. They were looking to collect multiple data points across the target material to see the rising and lowering of the expansion to determine the evolution of the entire cell.

Using non-contact laser sensors, the customer wanted to analyze the location(s) of the battery expansion to see if it was uniform or not while maintaining accuracy down to a micron. The laser displacement sensors station was for battery R&D testing, and the customer requested an out-of-the-box solution without the need for software programming on their end.

 

Acuity engineers were able to design a laser measurement system to provide the customer a small, customized solution. Acuity engineers selected the AR700-0125 laser models and a touch panel display with customized software. The AR700-0125 laser displacement sensor was selected due to its industry leading accuracy & resolution for triangulation sensors. With 0.125 inches of measurement range, linearity down to less than a micron, and resolution down to 0.16 microns, the AR700 was the right laser sensor for the job!
