1. A battery swapping control system, comprising: a control unit and a battery swapping device;
the control unit is configured to determine a battery model suitable for an electric vehicle;
the control unit is further configured to select a battery placing rack that meets a first condition as a first battery placing rack from at least one battery placing rack, and select a battery placing rack that meets a second condition as a second battery placing rack from the at least one battery placing rack, which the battery placing racks have several battery placing compartments for battery placement, the first condition is set to have a battery with the battery model, and the second condition is set to have an empty battery placing compartment;
the battery swapping device is configured for moving to a predetermined battery swapping position to remove an undercharged battery from the electric vehicle, transfer the undercharged battery to the second battery placing rack, and place it in the empty battery compartment, and then moving to the first battery placing rack to obtain a battery with the battery model from the first battery placing rack, transfer the battery with the battery model to the predetermined battery swapping position, and install it in the electric vehicle, wherein the predetermined battery swapping position refers to a position suitable for the removal and installation of batteries from/into the electric vehicle;
the battery swapping device is controlled by the control unit;
the control unit sends the following instruction to the battery swapping device, and the instruction is executed by the battery swapping device before the electrical vehicle is parked on a vehicle carrying platform:
a parking instruction for commanding the battery swapping device to be parked in a predetermined waiting position in advance;
the predetermined waiting position is the same as the predetermined battery swapping position when the predetermined battery swapping position is in parking available condition; or,
the predetermined waiting position refers to a position within a first distance threshold from the predetermined battery swapping position when the predetermined battery swapping position is in parking non-available condition;
the control unit is further configured to send a fine-tuning instruction to the battery swapping device for battery removal after the electric vehicle is parked on the vehicle carrying platform, which the fine-tuning instruction is configured to command the battery swapping device to move to the predetermined battery swapping position from the predetermined waiting position;
the predetermined battery swapping position is in parking available condition as all the following conditions are satisfied, otherwise, the predetermined battery swapping position is in parking non-available condition:
the predetermined battery swapping position is an empty space;
existing an access for the battery swapping device to move to the predetermined battery swapping position;
it is predicted that the battery swapping device does not obstruct an electric vehicle moving to the vehicle carrying platform when the battery swapping device is parked in the predetermined battery swapping position.
