Abstract

Provided is an electric vehicle control device in which a power supply device has a simple structure. A BMU power supply device () lowers a battery voltage to be suitable for the control voltage of a BMU (). A flyback down-regulator () lowers the battery voltage to be suitable for an input of a CPU power supply device () which forms a control voltage for a CPU (). A contactor () is disposed on a plus-side line which connects a battery () to a motor drive circuit (), and is opened and closed in response to an instruction from the CPU (). Control power for the down-regulator () is formed by the BMU power supply device (), and a main switch () is disposed to open and close a path through which the voltage of the control power is input to the down-regulator ().
