Biography[edit source]

A luminary in the fields of power electronics and motor drives, Philip T. Krein’s transformative contributions to energy conversion have broadly impacted electric and hybrid vehicle technologies. Krein began working on improving battery management for electric vehicles at a time when few believed this was a technical necessity. He developed a battery equalization technique using switched capacitor circuits that helped reduce the size and cost of battery management systems. His method extends the lifetime and efficiency of energy storage systems, which are critical to the success of today’s electric and hybrid vehicles. His contributions to vehicle systems optimization include high-fidelity dynamic models of vehicle systems and their interactions, linking fuel cells, batteries, ultracapacitors, and motor drives.

An IEEE Fellow, Krein is Director of the Grainger Center for Electric Machinery and Electromechanics at the University of Illinois at Urbana-Champaign and a Distinguished Professor at Zhejiang University, Hangzhou, China.
