The flipping apparatus comprises flipping members and a rotating mechanism. There are multiple flipping members, and each flipping member is provided with a constraint space for accommodating a battery so as to constrain the pose of the battery. The rotating mechanism is connected to each flipping member and is used for driving each flipping member to rotate around a rotation axis. Each flipping member is configured to be cyclically switched between a first position and a second position under the driving of the rotating mechanism; when the flipping member is at the first position, the battery enters the constraint space in a first pose; and when the flipping member is at the second position, the battery is flipped over to a second pose from the first pose and leaves the constraint space in the second pose. The flipping apparatus, and the battery flipping method can improve the battery flipping efficiency.
