[0022] Preferably, the display screen is arranged at the front end of the battery housing, in front of the connector a, and is electrically connected to the battery body.

[0023] With this design, the display screen is used to display the operating status of the battery body, such as temperature, power level, etc., which reflects the practicality of the device.

[0024] The beneficial effects of the utility model are:

[0025] When the utility model is in use, the battery shell is detachably mounted on the frame of the motorcycle via a connecting mechanism. This design makes it easy for the user to remove the battery shell from the frame of the motorcycle. During later maintenance, the battery body and the battery shell are also detachably designed, which not only makes it easy for the user to perform later maintenance, but also reduces the later maintenance cost, which is conducive to popularization and use.
