Hybrid vehicle control apparatus

An electric vehicle control apparatus comprising:

• a first motor generator;
• a second motor generator;
• a booster to boost an input voltage to the first motor generator and an output voltage from the second motor generator to expand an operable range of the first motor generator and an operable range of the second motor generator into a first expanded operable range and a second expanded operable range, respectively;
• and
• a controller to control the first motor generator to drive a load with regenerative power supplied during braking of an electric vehicle and to control the first motor generator to be driven at a first inefficient operating point within the first expanded operable range and to control the second motor generator to be driven at a second inefficient operating point within the second expanded operable range in a case where the regenerative power is used.

A method of controlling an electric vehicle comprising:

• controlling a first motor generator to drive a load with regenerative power supplied during braking of an electric vehicle;
• boosting an input voltage to the first motor generator and an output voltage from a second motor generator to expand an operable range of the first motor generator and an operable range of the second motor generator into a first expanded operable range and a second expanded operable range, respectively;
• and
• controlling the first motor generator to be driven at a first inefficient operating point within the first expanded operable range and controlling the second motor generator to be driven at a second inefficient operating point within the second expanded operable range in a case where the first motor generator drives the load.
