Battery pack storage system and automatic battery swapping station of electric vehicle

Abstract

The invention relates to a battery pack storage system and an automatic battery swapping station of an electric vehicle. The battery pack storage system comprises a battery pack storage device and a battery pack switching device; the battery pack storage device is provided with multiple layers of first battery pack storage units arranged in the height direction; the battery pack switching device is located on one side of the battery pack storage device in the first direction and provided with a second battery pack storage unit capable of moving in the height direction, and performs battery pack switching with the first battery pack storage units. The automatic battery swapping station comprises the battery pack storage system and a battery swapping platform which is arranged on one side ofthe battery pack storage system in the first direction and used for supporting and positioning a vehicle and lifting the vehicle to the preset battery swapping height. The battery pack storage deviceis arranged in avoidance areas at the bottoms of the first battery pack storage units and can allow a battery swapping trolley to pass. Accordingly, the occupied space is small, the battery pack storage number is large, the battery pack switching time is short, the battery swapping efficiency is high, the battery pack storage system and the automatic battery swapping station can be widely applicable to various places, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of battery replacement for electric vehicles, in particular to a battery pack storage system and an automatic battery replacement station for electric vehicles. Background technique [0002] With the development of electric vehicle charging and swapping facilities, more and more car owners choose to use automatic battery swapping stations to supplement electric energy for electric vehicles. The automatic substituting station designed by the applicant before the present invention is as figure 1 and figure 2 as shown, figure 1 In the automatic battery swap station shown, the orientation of the battery pack in the battery pack storage area is 90 degrees different from the battery pack in the battery replacement area. The battery pack needs to be rotated 90 degrees during the entire process, resulting in high cost, long battery swap time, and high system complexity. . During the battery swap process, it is ...

Problems solved by technology

Furthermore, there is only one layer of batteries in the battery pack exchange position, and each time the battery pack is exchanged, it needs to be picked up from a long distance, which takes a long time and has low power exchange efficiency

[0003] figure 2 In the automatic battery swap station shown in the scheme, the storage orientation of the battery pack in this solution is consistent with the replacement orientation. The battery pack no longer needs to be rotated 90 degrees during the battery swap process, but there is still a need to set up a space for the battery swap trolley to avoid, causing the battery swap system to fail. The space occupied will exceed the width of 3 parking spaces, and there is no margin for surrounding space

In addition, there is only one floor for battery pack exchange, and each battery pack exchange requires long-distance transport, which is time-consuming and inefficient.

In addition, the above-mentioned automatic battery swap station usually requires the battery swap trolley to be able to move up and down between the battery storage locations along the height direction of the battery swap position, so as to place or remove the battery pack. The lifting mechanism meets the lifting requirements. On the other hand, the battery replacement time is longer and the battery replacement efficiency is lower.

[0004] It can be seen that the existing automatic battery replacement stations have at least the following disadvantages: large floor space, small battery pack storage, long battery pack exchange time, and low power exchange efficiency, resulting in poor user experience.
