EV Battery Production and Development
Battery Cooling System Quality Control
In the induction process, the battery housing is heated to approx. 176°F, then the cooling is bonded, checked and leak tested.
The leak test can only cover a temperature delta of a maximum of 50 °F (test item temperature – room temperature). The cooling system is controlled by an optris infrared camera and a pyrometer, cooling the component to a temperature delta of 32…41 °F. (PI 400i, CT LT)
Global Lithium-Ion Battery Production
Integration of Cells to Modules
Temperature measuring after every step
Challenges:
- Shiny surfaces (reflection)
- No measurement
Solution measuring temperature:
- at the non reflective label
- at insulation of power connectors (anode, cathode)
Small insulators resulting in small measurement area (high resolution camera PI 640)
Detection of Short Circuits
- Automated alarm after detection
- Detection of defect cells and packs
Thermal imaging cameras monitor the first charging process of batteries. These provide an insight into the temperature distribution and possible short circuits. The hot-spot detection feature automatically recognizes and outputs deviations from the target temperature. The compact PI series cameras can be integrated quickly and easily into existing environments.
