<P>PROBLEM TO BE SOLVED: To provide a controller of an electric vehicle for protecting an accessory charging DCDC and for feeding to the accessory charging DCDC according to a fail cause. <P>SOLUTION: The controller of the electric vehicle is provided with: a high-voltage battery for supplying high voltage; a generator motor for generating electric power depending on a travel driving force and for generating the travel driving force itself; a booster for boosting and outputting high voltage to the generator motor side and for stepping down voltage input from the generator motor side; an accessory driven on low voltage; a step-down transformer for stepping down voltage supplied from the generator motor or the high-voltage battery; low voltage lines for supplying power to the accessory output from the step-down transformer; a first switch provided at one side of a positive or a negative electrode of the high-voltage battery; and a second switch provided at the other side of the positive or the negative electrode thereof. Furthermore, power-supply lines of the step-down transformer are connected to a location between the first switch and the booster and a location between the second switch and the high-voltage battery. <P>COPYRIGHT: (C)2007,JPO&INPIT |
