1. A drive unit housing for an electric vehicle comprising:
a first housing section forming a first compartment to house an electrical inverter comprising a capacitor and a power switching network;
a second housing section forming a second compartment to house an electric motor, the second housing section comprising perimeter sidewalls including a cylindrical housing to extend about a perimeter of a stator of the electric motor;
an inlet port to receive a fluid;
a shared wall separating the first compartment and the second compartment, the shared wall defining first fluid pathways in fluid communication with the inlet port to circulate the fluid to cool the electrical inverter, the first fluid pathways including a fluid channel and a fluid chamber, wherein the fluid travels through the fluid channel to cool the capacitor and then enters the fluid chamber to cool the power switching network; and
an outlet port in fluid communication with the first fluid pathways to discharge the fluid, wherein
the perimeter sidewalls define second fluid pathways in fluid communication with the inlet port to circulate the fluid to cool the electric motor, the second fluid pathways extending about a circumference of the cylindrical housing.
