。[Scope of Claim for Utility Model Registration] (1) A power converter that converts DC power into predetermined AC power and supplies it to a driving AC motor, a power transistor provided in this power converter, and the maximum power transistor of the above power transistor. A current limit setting circuit that sets a maximum current value for setting the current, two types of maximum current setting means provided in this current limit setting circuit, an accelerator sensor that detects instructions regarding acceleration of the vehicle, and a vehicle. a vehicle speed sensor that detects the speed of the accelerator; and a vehicle speed sensor that detects that it is starting acceleration when the output value of the accelerator sensor is greater than or equal to a predetermined value and the output value of the vehicle speed sensor is less than or equal to the predetermined value; and a switching means for switching the current setting means in the current limit setting circuit to the one with a larger current value for a short time, and is characterized by increasing the amount of current to the power transistor when the vehicle starts and accelerates, thereby increasing the starting acceleration. A start control device for electric vehicles. (2) In the device according to claim 1 of the utility model registration claim, the maximum current setting means has two Zener diodes that are grounded at one end, and the switching means has a connection between one of the Zener diodes and the ground. A start control device for an electric vehicle, characterized by turning on and off a transistor inserted between the two.
