Automotive Enginer Electrification Broadens Reach

by Bruno Lequesne, IEEE fellow

When thinking about the onset of engine electrification, some people initially reference the engine control unit (ECU), as well as the more recently introduced transmission control unit (TCU), since these ushered the era where electronics literally took control of engine operation. Today, beyond these “smarts,” there is a growing emphasis on the utilization of electric drive technology in engines and related peripheral automobile systems. While hybrid and electric vehicles have gotten a lot of well-deserved press due to the notable technical achievements that have been realized, there is also a lot more opportunity for utilizing electrification throughout the automobile. These areas include fuel injectors, valvetrain systems, exhaust recovery, superchargers, power steering systems and other accessory motors, and, of course, generators, starter-generators, and hybrid motors. Below we explore a few examples of recent, past, and future applications, as well as motor technology developments.

Upcoming Webinar:

120 kW High-Power Wireless Charging System Development
Presented by Veda Galigekere, Omer Onar, Jason Pries and Gui-Jia Su from
Oak Ridge National Laboratory
Tuesday, February 26, 2019, 1:00pm

Abstract:  This webinar focuses on a 120 kW wireless power transfer system developed at the Oak Ridge National Laboratory. This system can charge a 100 kWh battery pack from 20 to 80% state-of-charge in 30 minutes, which can bring the EV charging process closer to the fuel pumps at the gas stations. The webinar introduces the state-of-the art literature review on high-power wireless charging systems and details the design and development of the power electronics and electromagnetic coupling coils with their finite element analysis (FEA) based models. Design details and parameters of the system will be covered along with the experimental performance analysis of the system including the stage-by-stage power flow and efficiency of the system.   Read more.
