Mastering Motor Control in 48-V EV Thermal-Management Systems (Download)
As electrification reshapes the transportation industry, the use of smaller, denser, and more efficient electronic and electrical (E/E) assemblies is intensifying the need to manage heat stemming from higher power levels. A key contributor to this trend is the move from 12-V supply rails to 48-V systems. But this change is also transforming thermal strategies across the electric and hybrid electric vehicle (xEV) landscape.
Growing energy requirements, combined with the opportunity — and industry pressure — to reduce wiring weight and increase vehicle range and operating efficiency, are accelerating the use of higher-voltage power networks. This includes hybrid EVs that are adopting 48-V electrical systems to support active suspension, electric turbocharging, and an expanding set of pumps and blowers for battery, engine, and cabin cooling.
