AVL’s new line of test equipment for a trouble-free EV charging experience

The charging experience is one of the largest differences between vehicles with a battery and vehicles with a fuel tank. The core charging requirements are established and standardized, however, both the technology and applications are still in the early stages of maturity. Therefore, they are subjected to intense market pressure to expand, evolve, and improve…. Read more »

New battery inspection technologies: X-ray CT and Microscopy

Battery manufacturers face quality and process control challenges when battery components need to be inspected without being destroyed. The cells are inspected to map the electrode’s microstructure in 3D, the heterogeneities, foil stacking, welding joints, contacts, and their effect on battery aging and performance through several cycles of charging and discharging. X-ray microscopy and computed… Read more »
