Ultrasonic wire bonding (UWB), today’s preferred method for joining wires to battery packs in electric vehicles, requires very high surface cleanliness to assure successful bonds. Decontaminating battery terminals, however, can be a very difficult and time-consuming task. EWI has recently completed a study using laser cleaning technology on batteries prior to UWB of aluminum wire...

The integrity of joints (“stack-ups”) in vehicle frames is of utmost importance when it comes to safety, dependability, and public confidence in the automotive industry. But with up to a hundred joint variations in a car’s body-in-white, it is difficult to predict joint strength properties without extensive testing. Until now. EWI has developed a rapid...

Magnetic materials are essential to electric propulsion systems.  Key attributes of these materials include resistivity and grain size. Refining grain size increases magnetic saturation limits, and thus allows for lighter, more compact motor designs. Using powder-based processing is one way to achieve fine grain size, but the main methods for doing so are energy intensive,...
