Example 3

As shown in fig. 5, embodiment 3 provides a control method for a swapping station, and the control method is used to control the swapping station of embodiment 1. The battery replacement method comprises the following steps:

s1: after the control unit obtains a vehicle parking in-place signal, a first power changing instruction is sent to power changing equipment, and a second power changing instruction is sent to a double-station stacker crane;

and the double-station stacker crane receives the second battery replacing instruction and controls the first push-out mechanism to take out the full-charge battery pack from (a new bin of) a charging room of the battery replacing station and move to a battery replacing position of the battery replacing station for standby.

When a fully charged battery pack is taken out, the double-station stacker crane moves in a charging chamber of the battery replacing station through the horizontal travelling mechanism, moves to the opposite side of a battery rack in the charging chamber, wherein the fully charged battery pack is placed in the battery rack, takes out the fully charged battery pack from the battery rack, and then moves to the battery replacing position again. The battery replacement position refers to a position where a battery pack can be exchanged with the battery replacement device, and is generally a boundary between a charging room and a battery replacement platform.

S2: and the battery replacement equipment receives the first battery replacement instruction, takes the power-deficient battery pack off the vehicle, moves to a battery replacement position of the battery replacement station and aligns to the second push-out mechanism. At this time, the second push-out mechanism is empty.

S3: and the second push-out mechanism takes down the power-shortage battery pack on the power conversion equipment.

S4: the double-station stacker crane moves horizontally or vertically, so that the first push-out mechanism faces the battery replacement equipment. If the double-station stacker crane in embodiment 1 is used, the double-station stacker crane moves horizontally, that is, the horizontal travelling mechanism drives the first support and the second support to move horizontally together, so that the first push-out mechanism takes over the position of the second push-out mechanism and is opposite to the battery replacement equipment. If the double-station stacker crane in embodiment 2 is used, the double-station stacker crane moves vertically, that is, the first pushing mechanism and the second pushing mechanism move together in the vertical direction, so that the first pushing mechanism takes over the position of the second pushing mechanism and is opposite to the battery replacement equipment.

S5: the first pushing mechanism places the fully charged battery pack on the battery replacement equipment.

S7: the double-station stacker moves to place the electricity-deficient battery pack on the second push-out mechanism into a charging chamber of the battery replacement station, specifically a charging bin in the charging chamber, for charging.

The control method cancels the procedure of repeatedly placing the batteries in the battery replacing process of the stacker crane, and improves the battery replacing efficiency of the battery replacing station.
