Title:
PROPULSION CONTROL DEVICE OF ELECTRIC CAR
Document Type and Number:
WIPO Patent Application WO/2011/007430
Kind Code:
A1
Abstract:
A propulsion control device of an electric car has an inverter device connected to a DC power supply, an electric motor connected to the output of the inverter device, a converter device connected to the input of the inverter device, and a power storage device connected to the output of the converter device and is configured to discharge or charge part of electric power or part of regenerative power of the electric motor from/into the power storage device. The converter device has a converter control unit (46) which generates a charging current command value which is the command value of the current with which the converter device charges the power storage device, on the basis of a regenerative state signal indicating the state of a regenerative torque of the electric motor or the state of regenerative power, and which generates a charging/discharging current command value of the converter device on the basis of the charging current command value, to thereby perform control.
