CONTROL DEVICE FOR ELECTRIC VEHICLE
First Claim
1. A control device for an electric vehicle comprising:
- a first power conversion unit that converts a voltage input from an external power supply to a direct current having a predetermined value and outputs the direct current to a power storage element;
a second power conversion unit that receives an arbitrary power supply from the external power supply or the power storage element and converts power to an alternating current having a predetermined value;
an abnormality detection unit that detects an abnormal state of the first power conversion unit;
a first control unit that controls the first power conversion unit based on a detection result of the abnormality detection unit and generates a protection status signal based on the detection result; and
a second control unit that executes emergency control with respect to the second power conversion unit, when the protection status signal is input, which indicates that the first power conversion unit is in an abnormal state.

Abstract
A control device for an electric vehicle includes a converter circuit that converts a voltage input from an external power supply to a direct current having a predetermined value and outputs the direct current to a power storage unit, an inverter circuit that receives an arbitrary power supply from the external power supply or the power storage unit and converts power to an alternating current having a predetermined value, a converter control unit that controls the converter circuit based on a detection result of an abnormal state of the converter circuit and generates a protection status signal based on the detection result, and a inverter control unit that executes emergency control with respect to the inverter circuit, when the protection status signal is input, which indicates that the converter circuit is in an abnormal state.
