An apparatus for controlling a power supply of an electric machine in a vehicle comprises primary and secondary power supplies for supplying an electric power to the electric machine. In non-driving state of an engine, the primary power supply is selected as a power supply for the electric machine when an electric power consumption is over a predetermined value, and the secondary power supply is selected when the consumption is below the predetermined value. Therefore, the absentee receiving of facsimile information, the absentee recording of telephone message, etc. are carried out, even in a state of turning-off of an ignition switch. The secondary power supply is used mainly in the case that the electric machine is in waiting mode, so that the complete exhaustion of the secondary battery can be prevented.
