The invention discloses a positioning method and a positioning system for a battery compartment, wherein a positioning element is arranged on battery transfer equipment, and a reference object is arranged on the battery compartment. The positioning method comprises the steps that battery transfer equipment moves towards a battery compartment at a first speed in the driving direction of an electric vehicle, first standard position data representing the position of a reference object relative to a positioning element is obtained when the positioning element detects the reference object, a first signal is sent to the battery transfer equipment, and the battery transfer equipment stops moving when receiving the first signal; first instantaneous position data representing an instantaneous position of the positioning element is acquired; and the battery transfer equipment reversely moves at a second speed according to the first standard position data and the first instantaneous position data so as to approach the battery compartmentuntil the distance between the positioning element and the reference object in the driving direction of the electric vehicle is within an error allowable range. According to the positioning method, the battery compartment can be reliably positioned, and the reliability of battery replacement can be improved.

    本发明公开了一种电池仓的定位方法及定位系统。电池转运设备上设有定位元件,电池仓上设有参照对象,定位方法包括:电池转运设备沿电动汽车的行驶方向,以第一速度朝向电池仓移动,定位元件检测到参照对象时获取表示参照对象相对于定位元件的位置的第一标准位置数据,并发送第一信号至电池转运设备,电池转运设备在接收到第一信号时停止移动;获取表示定位元件的瞬时位置的第一瞬时位置数据;电池转运设备根据第一标准位置数据和第一瞬时位置数据以第二速度反向移动以接近电池仓,直至定位元件与参照对象之间沿电动汽车的行驶方向的距离位于误差允许的范围内。该定位方法能够较为可靠地实现对电池仓的定位,有利于提高换电的可靠性。
