Battery Power Terminal Layout for High-Current Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage devices face challenges with high-rate batteries that require large power connection terminals, occupying significant space and limiting the available space for battery cells due to the large sectional area needed for high currents, thereby reducing the energy storage capacity.
Innovation Solution
The battery design includes multiple power connection ends arranged in a specific direction to reduce the sectional area of individual connection lines, allowing for a more compact layout that maximizes space for battery cells while maintaining current demands, with electrode groups arranged to facilitate installation, maintenance, and reduce interference.

Engineering Contradiction Analysis
1Power
If a single large power connection terminal is used for high current transmission, then the current transmission capability is improved, but the space occupied by the power connection terminal increases
Solution Approach 1:
The single large power connection terminal is divided into multiple smaller power connection terminals (at least two positive electrodes and at least two negative electrodes). This segmentation allows the current to be distributed across multiple terminals, maintaining the required current transmission capability while reducing the space occupied by each individual terminal and the overall power connection group.
Solution Approach 2:
The power connection terminals are arranged in a specific spatial configuration (at least two in the first direction and at least two in the second direction, with the directions being perpendicular). This multi-dimensional arrangement optimizes the space utilization, allowing multiple terminals to be packed efficiently without increasing the overall footprint, thus maintaining current capability while minimizing space occupation.
2Power
If the power connection terminal occupies large space, then the current transmission capability is improved, but the space available for battery cells is reduced
Solution Approach 1:
By segmenting the power connection terminal into multiple smaller terminals arranged in a compact configuration, the total space required for power connections is reduced. This freed-up space can then be allocated to battery cells, increasing the battery capacity while maintaining the required current transmission capability through the distributed terminal arrangement.
3Area of stationary object
If multiple power connection ends are arranged in a compact configuration, then the space occupation is reduced, but the installation and maintenance complexity increases
Solution Approach 1:
The multiple power connection terminals are arranged in a structured two-dimensional configuration (first direction and second direction perpendicular to each other). This organized spatial arrangement, while compact, maintains regular patterns that facilitate systematic installation and maintenance procedures, reducing the complexity that would otherwise arise from arbitrary compact arrangements.
