Abstract: A connector assembly is provided for stacked electric power modules. Each of the electric power modules includes a front board, a back board, a top board, a bottom board, a left side board, a right side board, and a battery pack contained in the electric power module. The back board of the electric power module includes a connector module mounted thereto and the connector module includes at least one power connector connected to the battery pack and at least one signal connector. The at least one power connector and the at least one signal connector of the connector module are arranged to project beyond a horizontal surface of the top board.

Abstract: A sliding structure for stacked electric power modules is provided. The sliding structure includes a left slide structure and a right slide structure extending in a movement direction at a left top edge and a right top edge of the electric power module respectively. A left bottom edge and a right bottom edge of each electric power module are respectively provided with a counterpart left slide structure and a counterpart right slide structure extending in the movement direction and corresponding to the left slide structure and the right slide structure respectively. Multiple electric power modules are allowed to be stacked through the sliding structure.
