Battery Core Monitoring Module Integration for Reliable Tab Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a monitoring module in battery cores is challenging due to lack of a mounting position, difficulty in fixing the module, and environmental impact on power supply lines, leading to poor monitoring reliability and assembly complexity.
Innovation Solution
The monitoring module is integrated on the cover plate assembly or spacer within the battery core, with power supply lines arranged along these components, forming a loop with the pole core for stable power connection and reduced environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the monitoring module is mounted in the housing of the battery core without a specific mounting position, then the monitoring module can be installed, but it is difficult to reliably fix the monitoring module
Solution Approach 1:
The monitoring module is integrated with the cover plate assembly or spacer as a unified structure. The monitoring module is fixed to the cover plate assembly through adhesive or mechanical connection, or integrated into the spacer structure, eliminating the need for separate mounting positions in the housing and achieving reliable fixation.
Solution Approach 2:
The cover plate assembly or spacer serves as an intermediary carrier for the monitoring module. Instead of directly mounting the monitoring module in the housing, it is first fixed to the cover plate assembly or spacer, which then positions and secures it within the battery core structure.
2Volume of moving object
If components inside the housing are compact with little available space, then the battery core is compact, but the arrangement of power supply lines for the monitoring module is difficult
Solution Approach 1:
The power supply lines are pre-arranged along the cover plate assembly or spacer structures during the assembly process. The monitoring module's power supply routing is planned and positioned in advance through these components, avoiding the need to navigate tight spaces within the housing after assembly.
Solution Approach 2:
The cover plate assembly or spacer acts as an intermediary pathway for power supply lines. Instead of routing wires directly through the compact housing interior, the power lines are arranged along the external surfaces or structures of the cover plate assembly or spacer, providing easier access and routing.
3Use of energy by moving object
If the power supply line is arranged in the compact housing, then power can be supplied to the monitoring module, but the operating state of the power supply line is easily affected by environmental conditions
Solution Approach 1:
The cover plate assembly or spacer serves as a protective intermediary for the power supply lines. By arranging power lines along these external structures rather than within the internal housing cavity, the lines are shielded from environmental conditions such as electrolyte exposure, temperature fluctuations, and mechanical stress from internal components.
Solution Approach 2:
The cover plate assembly or spacer provides a protective barrier (shell-like structure) that encloses or shields the power supply lines from the harsh battery environment, while still allowing the lines to conduct power effectively to the monitoring module.
4Reliability
If the monitoring module is integrated on the cover plate assembly or spacer, then connection strength is improved, but assembly steps may be increased
Solution Approach 1:
The monitoring module is combined with the cover plate assembly or spacer as an integrated unit. This merging of components achieves strong mechanical connection and reliable positioning, while the integrated design allows the monitoring module to be pre-assembled with the cover plate or spacer before final battery assembly, actually simplifying the overall assembly process.

AI summary
The present disclosure relates to a battery core, a battery pack, and an electric device. The battery core includes a cover plate assembly, a housing, a pole core, a spacer, and a monitoring module. The pole core is fixed in an inner cavity formed by enclosing the cover plate assembly and the housing. The spacer is fixed to a side of the pole core facing the cover plate assembly. The pole core is provided with a tab. The tab passes through the spacer and is fixed to the cover plate assembly. The monitoring module is fixed to the cover plate assembly or the spacer. The monitoring module is electrically connected to the tab to supply power to the monitoring module. In the present disclosure, the monitoring module of the battery core is integrated on the cover plate assembly or the spacer, which improves connection strength between the monitoring module and the battery core, so that the monitoring module has higher reliability. In addition, a power supply line of the monitoring module may be arranged along the cover plate assembly or the spacer, to reduce an impact of an environment on the monitoring module, so that the monitoring module has a better monitoring effect. In addition, a battery core assembly step is simplified, and assembly efficiency of the battery core is improved.
