Abstract: A rotating electric machine unit includes a rotating electric machine, a high heat generation circuit and a low heat generation circuit both of which are electrically connected with the rotating electric machine, a first cooler, a first-coolant supplier, a second cooler and a second-coolant supplier. The first cooler is configured to cool both the high heat generation circuit and the low heat generation circuit with a first coolant. The first-coolant supplier is configured to supply the first coolant to the first cooler. The second cooler is configured to cool the rotating electric machine with a second coolant. The second-coolant supplier is configured to supply the second coolant to the second cooler. The second-coolant supplier is formed integrally with a low heat generation circuit-cooling part of the first cooler. The second-coolant supplier includes a heat exchanger via which heat is exchanged between the first coolant and the second coolant.

Abstract: A drive system to be applied to a vehicle is provided which includes a chargeable and dischargeable electric storage device, and in which the electric storage device is capable of being charged by power supply from an external power supply outside the vehicle. The drive system includes a rotating electrical machine, an inverter connected to the rotating electrical machine, a converter configured to transform a power supply voltage of the electric storage device and output the transformed power supply voltage to the inverter, and charging wirings which are capable of being electrically connected to the external power supply. The charging wirings are connected to connection points between the inverter and the converter.
