Zusammenfassung:	[Task] To provide a vehicle drive system capable of changing a characteristic of a motor while suppressing a vehicle system from becoming unstable.[Solution] The vehicle drive system includes: a motor having a stator and a rotor; and a battery. The stator has plural primary conductors, the rotor has plural secondary conductors, and the battery has plural battery modules. A motor ECU and a battery ECU are provided. The motor ECU can change the number of poles of the motor by increasing/reducing the number of primary conductor groups, in each of which a current flows in the same direction and the primary conductors are continuously aligned in a circumferential direction. The battery ECU can change a connection mode of battery module pairs, which are electrically connected to each other, between in series and in parallel. The ECU, the motor ECU, and the battery ECU are configured to initiate changing the number of the poles (S9, S10) and changing the connection mode of the battery module pairs (S13, S14) at different timings from each other (S11) .
