Electric vehicle (EV) battery management system (BMS) development and testing have some specific challenges, so we gathered a team of expert panelists from the University of California Merced and the University of Applied Sciences Ravensburg-Weingarten to discuss how hardware-in-the-loop (HIL) solutions can address them. This article is a part of our HIL e-Mobility series and includes access to the webinar recording with a dedicated BMS HIL Testing demo.
