1Volume of stationary object
If conventional battery modules are installed in wind power generator towers, then the battery module can be mounted, but the space utilization is low and it is difficult to install battery modules with sufficient capacity
Solution Approach 1:
The patent adopts a cylindrical battery module design that matches the cylindrical shape of wind power generator towers. The module case is formed as a cylinder with battery cells arranged radially around the central axis, allowing the battery module to fit efficiently within the circular cross-section of the tower, thereby maximizing space utilization while accommodating sufficient battery capacity.
Solution Approach 2:
The patent transitions from conventional planar battery arrangements to a three-dimensional radial configuration. Battery cells are disposed horizontally in a radial pattern around the central axis, with electrode terminals facing inward. This spatial reconfiguration enables efficient use of the vertical cylindrical space within the tower, allowing both high space utilization and sufficient battery capacity.
2Productivity
If cylindrical battery cells are disposed horizontally with electrode terminals facing the central part, then vertical extension is easy, but the structural complexity increases
Solution Approach 1:
The battery module is divided into multiple horizontal layers, with each layer containing battery cells arranged radially. The frame structure is segmented into corresponding layers that can be independently assembled and then stacked vertically. This segmentation enables easy vertical extension by simply adding more layers, while each individual layer maintains a manageable structural complexity.
Solution Approach 2:
The frame structure is designed as a universal multi-functional component that provides both mechanical support for the battery cells and electrical connection pathways through integrated busbars. The circuit board is positioned at the central axis to handle both control and power transmission functions. This multi-functionality reduces the number of separate components needed, thereby reducing overall structural complexity while enabling easy vertical scaling.
