Claim 5:
6. 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, select one set angle from a plurality of predetermined set angles, that is closest to an electrical angle of the rotating electric machine that is detected by an angle sensor and is input from an outside of the drive device, and set a switching signal for the DC/AC inverter circuit based on the selected one set angle, instead of the electrical angle detected by an angle sensor.
