Abstract
There is obtained an electric-vehicle controller that prevents energy stored in a power storage unit from being discharged in the case where a collision, a derailment, or breakage of an overhead line occurs. The electric-vehicle controller is provided with a DC-to-DC converter one terminal pair of which is connected to the DC power source side of the inverter, a power storage unit that is connected to the other terminal pair of the DC-to-DC converter and stores electric power, a switch provided between the power storage unit and the DC-to-DC converter, and a control unit that opens the switch in the case where abnormal circumstances may occur or have occurred.

9. An electric-vehicle controller comprising:
-
an inverter that is connected to a DC power source and drives a motor; a DC-to-DC converter having one terminal pair that is connected to the DC power source side of the inverter; a power storage unit that is connected to the another terminal pair of the DC-to-DC converter and that stores electric power; a switch disposed between the power storage unit and the DC-to-DC converter; and a control unit that opens the switch so as to separate the power storage unit from the DC-to-DC converter, in response to an emergency brake status signal for an electric vehicle that is input thereto. - View Dependent Claims (10, 11, 12)
