Abstract: A battery accommodating mechanism includes a bottom plate, a battery accommodating device, a pin plate assembly and a top plate assembly sequentially arranged from bottom to top. The battery accommodating device includes a battery tray and a tray bottom plate assembly and mounting holes and cooling fans. The top plate assembly includes a top plate, a guide shaft slidably connected to the linear bearing embedded in the mounting holes, a circuit board and a driving member driving the bottom plate of the tray to move up and down so that the electrodes of the batteries in the battery tray contact and separate from the pin plate assembly to form the batteries. The pin board assembly includes a mounting board with pins arranged on the bottom surface of the mounting board and electrically connected with the pin board circuit board. The invention improves the efficiency of capacity dividing.

Abstract: A formation capacity-grading equipment for a cylindrical lithium-ion battery comprises a rack, a charge and discharge power box for charging and discharging the cylindrical lithium-ion battery, a battery clamping mechanism for clamping the positive and negative electrodes of the cylindrical lithium-ion battery, a battery tray for placing the cylindrical lithium-ion battery, and a controller, wherein the rack is provided with several layers of work stations for formation and capacity grading of the battery; the charge and discharge power box and the battery clamping mechanisms are provided at each layer of the work stations; a power transmission end of the charge and discharge power box is electrically connected to a power transmission end of the battery clamping mechanism; and a control end of the charge and discharge power box and a control end of the battery clamping mechanism are in signal connection respectively with a signal transmission port of the controller.
