The driver can slowly reduce the speed to prevent sudden braking from causing damage to the occupants, and the occupants can be evacuated in an orderly manner; after the cooling electric fan 702 is started, wind blows into the cooling cover 701 to cool the battery pack body 201, and the wind is discharged from one side of the battery pack body 201. After the battery pack body 201 is separated from the mounting frame 101, the alarm sliding column 601 loses the extrusion of the inner side of the mounting frame 101. Under the extrusion of the detection spring 603, the alarm sliding column 601 drives the micro switch 602 to move outward, and the micro switch 602 is no longer pressed. At this time, the micro switch 602 can control the alarm prompt light 202 to light up and alarm, which mainly serves as a warning for overheating of the battery without spontaneous combustion.
