To provide a drive device for an electric vehicle that can avoid a motor-lock state even when an electric vehicle is brought into a lock state.SOLUTION: A drive device 10 for an electric vehicle includes: a first motor M1; a second motor M2; a planetary gear mechanism 20 for outputting a drive force by merging outputs from the first motor M1 and the second motor M2; and a control unit 50 for controlling at least respective rotation numbers of the first motor M1 and the second motor M2. The control unit 50 allows the first motor M1 and the second motor M2 to rotate when the electric vehicle is brought into a lock state.SELECTED DRAWING: Figure 1 【課題】電動車両がロック状態となった場合であってもモータのロック状態を回避することができる電動車両の駆動装置を提供する。【解決手段】第１モータＭ１と、第２モータＭ２と、第１モータＭ１及び第２モータＭ２の出力を合流させて駆動力を出力する遊星歯車機構２０と、少なくとも第１モータＭ１及び第２モータＭ２のそれぞれの回転数を制御する制御部５０と、を有する電動車両の駆動装置１０であって、制御部５０は、電動車両がロック状態になった場合に、第１モータＭ１及び第２モータＭ２を回転させる。【選択図】図１
