PROBLEM TO BE SOLVED: To provide a control device of an electric vehicle capable of suppressing deterioration or the like of a battery caused by reduction in cell voltage.SOLUTION: A control device of an electric vehicle is configured to: reduce output torque of a traveling motor 3 by using first reduction rate when slip of a driving wheel 5 occurs; and further change reduction rate of the output torque to second reduction rate larger than the first reduction rate, when voltage of a battery 2 drops below a determination threshold value.SELECTED DRAWING: Figure 3

    【課題】セル電圧の低下に起因するバッテリの劣化等を抑制することができる電動車両の制御装置を提供する。【解決手段】駆動輪5のスリップが発生すると、走行用モータ3の出力トルクを第1の低下率で低下させ、さらに、バッテリ2の電圧が判定閾値以下まで低下すると、出力トルクの低下率を第1の低下率よりも大きい第2の低下率に変更する構成とする。【選択図】図3
