INDUSTRIAL CT SCANNING OF EV BATTERIES
DETECTING DEFECTS USING CT IN EV BATTERIES
Haven Metrology was the only CT lab out of seven around the globe to be able to detect cracks inside these EV battery modules – from Asia, Europe, and the US.
After spending a month on R&D for a method, loading fixture, and Volume Graphics workflow we were awarded participation in a 3,000 piece sort. Our customer purchased their own CT to assist in maintaining a strict deadline. Due to NDAs no proprietary information or methodology can be shared.

Below you can see examples of cracks in both rendered conditions and slice data.
A trusted fixture builder created an entirely customizable fixture that we can fine tune for perfect alignments inside of our CT.

The same client is now sending us an assortment of battery modules for failure analysis. Here is a module that caught fire. We were able to visualize the damage to the circuit board.
