An e-charger includes an outer housing and a rotor supported for rotation within the outer housing. A motor assembly is housed within the outer housing and includes an electric motor and a motor case. The electric motor is encased within the motor case. The electric motor is configured to drivingly rotate the rotor within the outer housing. Furthermore, the e-charger includes a cooling system configured to receive a coolant. The cooling system includes a manifold passage defined in the outer housing. The cooling system includes a first motor cooling circuit and a second motor cooling circuit that are cooperatively defined by the outer housing and the motor case. The first motor cooling circuit and the second motor cooling circuit are fluidly connected to the manifold passage. The manifold passage is configured to distribute a flow of the coolant between the first motor cooling circuit and the second motor cooling circuit.
