The invention relates to a battery box supporting roller and an energy storage device using the same. The battery box support roller comprises a rotating shaft and a rolling support body. The rollingsupport body is used for the rolling support of a bottom surface of a battery box, the outer peripheral surface of the rolling support body is provided with more than two annular grooves, and the annular grooves are arranged with intervals in the axial direction along the rolling support body. The groove rolling support is divided into multiple support regions in the axial direction by the annulargrooves, when the battery box is not flat enough or the mounting level of the roller is poor, a support region is more easily deformed to fit the surface of the battery box, the grooves can also accommodate protrusions on a part of the battery box, the support area of the battery box support roller to the battery box is ensured, the battery box can be protected from being worn due to uneven force, and the problems of eccentric wear and damage to the support roller can be prevented well.
