Poor quality cell interconnects can lead to several problems, such as increased resistance, leading to increased heat generation, voltage drop, and reduced overall performance. Also poor interconnects can also lead to safety hazards such as arcing, which can cause fires or explosions. Battery cell interconnect issues must be caught during battery production. 

Current test methods:

• rely on physical contact with the interconnects, risking damage 
• optically check for visible defects and not electrical properties 
• measure temperature variations and not electrical properties 

Hover Sense non-contact uses advanced magnetic field measurement techniques to assess the interconnect quality without physical contact. This alleviates any concerns about battery surface degradation or probe markings. 

Hover Sense non-contact probe module can be used to test both laser-welded and wire-bonded interconnects.
