END INSULATING PLATE, BATTERY DEVICE AND ASSEMBLING METHOD OF BATTERY DEVICE

An end insulating plate is arranged in a battery device to insulate a battery apparatus. The end insulating plate has a glue baffle disposed at a bottom portion, is bendable, and has first and second states. In the first and second states, the glue baffle is bent towards a first larger surface of the end insulating plat, which is the larger surface at a side of the end insulating plate facing away from the battery apparatus. In the first state, the glue baffle is bent at a first inclination angle. In the second state, the glue baffle is bent at a second inclination angle. The first inclination angle is greater than the second inclination angle. When bending of the glue baffle is changed from the first inclination angle to the second inclination angle, the glue baffle pushes glue away from the bottom portion of the end insulating plate.
