[0002] With the booming development of the two-wheeled electric vehicle market, the number of batteries in two-wheeled electric vehicles has increased dramatically. There have also been several fire safety accidents caused by charging batteries in residential areas, which has greatly promoted the promotion and popularization of battery swapping cabinets for two-wheeled electric vehicles. These cabinets allow for the replacement of batteries in two-wheeled electric vehicles outdoors, thereby minimizing the need to charge batteries in residential areas.

[0003] As a result, manufacturers of battery swapping cabinets for two-wheeled electric vehicles have sprung up like mushrooms after rain. Due to the current lack of unified standards, the battery sizes, interfaces, and protocols of two-wheeled electric vehicles produced by different manufacturers vary, leading to the following problems: 1. The same battery swapping cabinet is not compatible with multiple types of batteries. During battery swapping, it may be discovered that the battery type is incompatible, and a swapping cabinet compatible with the battery type requires a longer distance to reach; 2. The swapping cabinet lacks backward compatibility. Updated protocols / wiring may not be compatible, causing the swapping cabinet to become obsolete along with the battery.
