Abstract
An electric power conversion apparatus includes a rotating electric machine including armature windings, a first inverter connecting the armature windings with a first storage battery, a second inverter connecting the armature windings with a second storage battery, a changeover switch configured to connect or disconnect between first and second positive buses or between first and second negative buses, and an operating unit configured to perform, with the changeover switch being in an ON state, first and second energization processes alternately. In the first energization process, electric current is supplied from the first storage battery to the second storage battery via the first inverter, at least one of the armature windings and the second inverter. In the second energization process, electric current is supplied from the second storage battery to the first storage battery via the second inverter, at least one of the armature windings and the first inverter.
