Abstract

Electrification of automotive systems presents significant opportunities for improvements in cooling system
efficiency and performance. This paper describes an effort to develop an analytic platform for Hanon Systems to
evaluate the electrification potential for powertrain cooling systems. The paper describes the development of a
baseline diesel cooling system model based on the Ford 6.7L Power Stroke diesel. A variant of the system with
electric pumps is also modeled. Performance of the baseline conventional and electric pump system are compared
on a typical automotive drive cycle to quantify potential benefits of the electric pump system and advanced controls.
