Abstract
In charging first and second power storage devices from a charging station, an inverter ECU controls first and second inverters to convert AC power received at first and second neutral points into DC power and output the DC power to a power supply system. A converter ECU converts in voltage the electric power received from the first and second inverters to be charged and outputs the converted electric power to the first and second power storage devices, and for low temperature, controls first and second converters to allow the first and second power storage devices to communicate electric power therebetween.
