Stackable Battery Box Eliminating Frame for Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems for commercial vehicles inefficiently utilize space due to the need for a battery frame that exceeds the dimensions of the battery boxes, resulting in unused space and gaps between layers.
Innovation Solution
A battery box design allowing for direct stacking without a frame, utilizing threaded and unthreaded holes for secure connection, sealing grooves for uniform compression, and integrated cooling vents for efficient heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery frame is used to mount battery boxes layer by layer, then the safety and installation of batteries are ensured, but the space utilization is reduced due to gaps between the battery frame and battery boxes
Solution Approach 1:
The invention merges the battery box with the stacking structure by integrating threaded holes directly into the battery box body. The upper battery box serves dual functions as both a container and a mounting structure, eliminating the separate battery frame while maintaining stacking capability and safety.
Solution Approach 2:
The invention extracts the mounting function from the battery frame and relocates it directly to the battery box. The threaded holes are formed directly on the battery box surface, removing the intermediary battery frame structure and eliminating the gaps between frame and battery boxes.
2Ease of manufacture
If the battery frame dimensions are made larger than the battery boxes, then the safety and installation are facilitated, but the remaining space is not sufficiently used
Solution Approach 1:
The invention combines the mounting holes directly with the battery box structure. The threaded holes are formed on the battery box surface itself, merging the container function with the mounting function, thereby eliminating the need for oversized frames while maintaining installation ease.
3Device complexity
If threaded holes are formed in the battery box for stacking, then direct stacking without frame is enabled, but the structural complexity increases
Solution Approach 1:
The invention merges the mounting structure directly into the battery box by forming threaded holes on the battery box surface. This integration eliminates the separate battery frame while the threading process itself becomes part of the battery box manufacturing, balancing structural simplification with manufacturing feasibility.

Implementation Method 1
screw fasteners penetrate through the unthreaded screw mounting holes of an upper battery box and the threaded holes of a lower battery box to fixedly connect the upper battery box and the lower battery box
Implementation Method 2
a portion, corresponding to the groove in the upper brim, of the contact plane is used for compressing the sealing strip

AI summary
The invention provides a battery box capable of being stacked layer by layer and a battery system. The battery box is configured as a box structure. Threaded holes are circumferentially formed in an upper portion of the battery box, and unthreaded screw mounting holes corresponding to the threaded holes are formed in a lower portion of the battery box. Screw fasteners penetrate through the unthreaded screw mounting holes of an upper battery box and the threaded holes of a lower battery box to fixedly connect the upper battery box and the lower battery box. A battery frame is eliminated, and the upper battery box is directly stacked on the lower battery box, such that the space utilization of battery boxes in the battery system is greatly increased, and a vehicle can be loaded with more batteries under the same volume; by adopting this technical solution, the cooling system can also exert a benefit effect on the tops of batteries, thus improving heat management efficiency; in addition, the technical solution facilitates connection of wires and water lines between the battery boxes.
