The invention discloses a parking device, a parking system and an electric vehicle. The parking device comprises a synchronous motor and a locking mechanism; the synchronous motor comprises a stator and a rotor. The stator is fixed to the electric vehicle. The rotor is in transmission connection with wheels of the electric automobile; the locking mechanism is used for locking the rotor, so that a vector included angle between the rotor and the stator is 0 degree or 180 degrees; in the boosting charging process, the torque output by the synchronous motor has the minimum absolute value. In the case of rapid power-off or other emergency power-off, the tooth breaking phenomenon of a mechanical transmission structure caused by rapid power-off can be avoided, and the NVH problem can be relieved or eliminated.

    本申请公开了一种驻车装置、驻车系统及电动汽车。驻车装置包括同步电机和锁止机构;同步电机包括定子和转子,定子固定于电动汽车;转子用于传动连接电动汽车的车轮;锁止机构用于锁止转子,以使转子的与定子之间的矢量夹角为0°或180°;在升压充电过程中,同步电机输出的扭矩具有最小绝对值。在快速下电或其他紧急情况下电时可以避免因为快速下电导致的机械传动结构发生的打齿现象,可以缓解或消除NVH的问题。
