Abstract:
A hybrid vehicle including one or more in-wheel motors, a power electronics supplying power to the one or more in-wheel motors, and a Rankine cycle system is described. The Rankine cycle system includes a pump driving a working fluid, a first three-way valve having an input, a first output, and a second output. The Rankine cycle system also includes, a second three-way valve having a first input, a second input, and an output, an evaporator receiving the working fluid from the output of the second three-way valve and heating the working fluid utilizing heat from an exhaust gas from an engine, an expander receiving the working fluid from the evaporator, and a radiator cooling the working fluid received from the expander.
