Battery Heat Conducting Medium Introduction Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing batteries are inefficient in introducing a heat conducting medium into the intermediate space between the battery housing and cell module, leading to a time-consuming process and potential damage due to excessive pressure.
Innovation Solution
The method employs an introduction device that operates in two modes: the first mode uses a preset volume flow for rapid introduction, and the second mode adjusts to a preset pressure to prevent excessive pressure, allowing for quick and reliable introduction of the heat conducting medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the heat conducting medium is introduced quickly with high volume flow, then the manufacturing process becomes more efficient, but excessive pressure may damage the battery components
Solution Approach 1:
The introduction device operates in two dynamic modes: a first mode with high volume flow for rapid filling, and a second mode with pressure limitation for safe completion. The system dynamically switches between these modes based on the filling stage, allowing both high productivity and process reliability.
Solution Approach 2:
The invention changes the operating parameters of the introduction device between two distinct modes. The first mode uses high volume flow parameters for rapid introduction, while the second mode uses limited pressure parameters for safe completion, resolving the contradiction between speed and safety.
2Reliability
If the heat conducting medium is introduced with limited pressure, then component damage is prevented, but the introduction process becomes time-consuming
Solution Approach 1:
The introduction device dynamically adjusts its operating mode based on the filling stage. Initially, it operates in a high-speed mode to quickly fill most of the intermediate space, then switches to a pressure-limited mode only when necessary to complete the filling, minimizing time loss while ensuring reliability.
Solution Approach 2:
The first operating mode intentionally uses excessive volume flow (higher than what would be safe for the entire process) to rapidly fill the majority of the intermediate space. The second mode then applies pressure limitation only for the remaining portion, achieving both speed and safety.
3Productivity
If a single operating mode is used for introduction, then the device operation is simplified, but it cannot simultaneously achieve rapid introduction and prevent excessive pressure
Solution Approach 1:
The introduction device incorporates dynamic mode switching capability, allowing it to adapt its operating characteristics based on the filling stage. This dynamic approach enables the simple operation of selecting one of two predefined modes while achieving the complex goal of both rapid introduction and pressure control.

AI summary
A method for manufacturing a battery, which has a battery housing and at least one cell module, the cell module being introduced into the battery housing to form an intermediate space between a wall of the battery housing and the cell module, and a heat conducting medium then being introduced by an introduction device into the intermediate space. One operating mode is selected from a first operating mode of the introduction device and a second operating mode of the introduction device and is used for introducing the heat conducting medium, with the introduction of the heat conducting medium in the first operating mode occurring with an introduction volume flow set to a preset volume flow and in the second operating mode occurring with an introduction pressure set to a preset pressure.
