Vehicle electrification

Laser welding techniques are exceptionally well suited for the electrification industry due to the technology’s high speed, low-heat input, precision, and versatility. However, changing the variables of a laser welding application – power, wavelength, travel speed, material, and more – can greatly impact the success of a weld. Laser specialists Dean Langenkamp and Jacob Hay...

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,...

Auto manufacturers and suppliers need a valid, reliable way to detect flaws in electric vehicle battery enclosures, or modules. EWI has developed an inexpensive testing method with demonstrated feasibility! Our team validated an EV battery testing procedure involving colorimetric chemical reagents and a reactive gas. It’s a high-resolution marking method that’s faster and clearer than...
