ABSTRACT:
A protection device is provided for a control apparatus for use in an electronic automobile with a motor and a transistor for driving the motor. The protection device comprises a short-circuit detecting device for detecting a short-circuit state of the transistor and, an excess voltage detecting device connected to the transistor for comparing a voltage applied to the transistor and motor of the control apparatus with a predetermined voltage, thereby detecting an excess voltage applied when a plug of a charger is erroneously connected to a plug receiver of the control apparatus.
