Measurement Sensors for the Battery

Sensors not only help maintain safety but also product consistency. In lithium-ion battery production, the charge and discharge cycles of these batteries produce heat and pressure fluctuations that can lead to delamination or thermal runaway if left unchecked.

Electric vehicle engineers no longer have to perform manual quality checks as a sensor can perform the checks for them. With production being more streamlined, manufacturers are now able to focus on efficiency.

There are a variety of sensors used in the battery pack manufacturing process. Pressure sensors are used to detect swelling on the battery housing that could otherwise result in a structural failure. During formation, these sensors also help reduce variability between cells. Thermal imaging sensors are used to monitor the battery’s initial charging process and detect potential hot spots that could lead to overheating.

Laser displacement sensors and 3d profile sensors provide precise measurements of weld alignment and coating thickness. These sensors can detect irregularities early and prevent costly defects. Additionally, ultrasonic sensors are used to inspect electrode and separator films for tears and double feeds.

Battery packs must be assembled correctly and tested to avoid safety hazards and performance issues. Sensors used in battery manufacturing are used to monitor the battery throughout production to verify that it won’t short-circuit or overheat. To help maintain integrity, vision systems and laser displacement sensors help verify that everything is properly aligned and stable. These battery inspection sensors also enable and track unique identification codes that help monitor quality control. It also helps manufacturers act quickly in the event of a malfunction.

During the battery manufacturing inspection process, a sensor’s main job is to keep production on track. The sensors monitor everything from the coating thickness of electrode materials to the final appearance of the battery. Optical sensors guide electrode and separator films to prevent misalignments that could cause defects. Sensors also provide consistent and precise material positioning.

Real-time monitoring with advanced sensor systems keeps quality consistent while streamlining processes and minimizing human error. These sensors also enhance safety by identifying overheating or structural issues before they can escalate. Advanced sensors mean fewer mistakes and a higher quality product.
