Patent application: Thermal kinetic energy recovery system for hybrid vehicle

Ben Welter - Monday, January 28, 2019

U.S. patent application 20190023113 (applicant Eaton Corp., Cleveland, Ohio):

"A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a waste heat recovery (WHR) system, a brake assembly and a phase-change thermal heat storage system. The WHR system selectively circulates a WHR fluid in the transmission system. The brake assembly selectively couples a transmission output shaft to a drive axle. The brake assembly is configured to operate in a braking mode that retards relative rotation between the transmission output shaft and the drive axle while generating heat. The heat storage system includes a housing defining at least one cavity and a fluid transfer manifold. A phase-change material is disposed in the cavity that is configured to change phase during the braking mode."
