Claim 3:
4. A drive device for a rotating electric machine, comprising:
a power conversion circuit configured to convert DC power supplied from a storage battery into AC power, supply the AC power to the rotating electric machine, and includes a DC/AC inverter circuit, and
a processor configured to, when the storage battery is to be charged, and a temperature of the storage battery is lower than a set temperature suitable for charging, set a switching signal for the DC/AC inverter circuit so that an electrical angle of the rotating electric machine input from an outside of the drive device is matched with a phase at which a difference between a maximum value and a minimum value of a current amount of each phase of the rotating electric machine is minimum.
