Abstract: An electric lifting frame includes a lifting pedestal and a remote control. The lifting pedestal includes a supporting base, a lifting rod detachably connected to the supporting base, and a transmission mechanism, a motor, a controller, and a power supply provided at the lifting rod. The motor is configured to effect extension and retraction of the lifting rod via the transmission mechanism. The controller is configured to control starting and stopping and a rotation direction of the motor. The power supply is configured to supply electric energy to the motor and the controller. The controller is further configured to determine a remaining capacity of the power supply and calculate a number of remaining available times of use according to the remaining capacity, a power of the motor, and a stroke of the transmission mechanism.

Abstract: A display cart includes a pedestal, a lifting frame, and a power supply apparatus including a battery arranged within the pedestal and configured to supply power to an electric apparatus, an external power supply configured to supply power to the battery and/or the electric apparatus, and a capacity management system. The capacity management system includes a control device, a power delivery device, and a capacity statistic device. The control device determines output power of the electric apparatus. The capacity statistic device determines a remaining capacity in the battery, calculates a remaining power supply duration according to the output power of the electric apparatus, and sends a statistic result to the control device. The control device further controls the power delivery device to supply power to the electric apparatus according to the statistic result.
