Patent ID: 7991520

Claim:
In a control apparatus for an electric car, wherein an auxiliary power source device for feeding electric power to a load, a drive control device for controlling a driving motor, and a power storage system having a power storage device are connected in a parallel relationship; a control apparatus for an electric car, wherein the power storage system comprises: a DC-DC converter connected in parallel with a capacitor; a voltage detector which detects a voltage of the capacitor; a power storage portion which has a power storage device for exchanging electric power with said DC-DC converter; and a power storage system control portion which controls said DC-DC converter so that either electric power or a current to be absorbed/emitted by the power storage system, or the voltage of the capacitor becomes a predetermined value, wherein, in a case where said control apparatus for the electric car exchanges electric power with an external device, said power storage system control portion performs a control so that the electric power or the current to be absorbed/emitted by the power storage system does not agree with a sum between electric power or a current of the drive control device and the electric power or a current of the auxiliary power source device.
