Beschreibung
Zusammenfassung:	A charging system charges, through an external charger, a first voltage source and a second voltage source that supply electric power to a rotating electric machine that includes coils of phases. A first inverter is connected to respective first ends of the coils and the first voltage source. A second inverter is connected to respective second ends of the coils and the second voltage source. A first switch is provided on a first power supply line that connects a high potential side of the first voltage source and a first external connection terminal that is connected to a high potential side of the external charger. A second switch is provided on a second power supply line that connects a low potential side of the second voltage source and a second external connection terminal that is connected to a low potential side of the external charger.
