Solution Overview
Problem
Existing battery packs face difficulties in easily connecting and disconnecting electrode terminals of battery modules, making assembly and maintenance challenging due to the need for nut fastening, which can lead to quality issues like loose connections and contact defects.
Innovation Solution
A battery pack design featuring socket terminals with elastic contactors, flexible bus bars, and a case that allows for press-fitting of electrode terminals, enabling easy electrical connection and disconnection without the need for additional tools, and incorporating a sub plate for support and accommodation of modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bus bars with through-holes and nuts are used to connect electrode terminals, then electrical connection is achieved, but assembly and disassembly become difficult and time-consuming
Solution Approach 1:
The patent replaces the traditional nut fastening mechanism with a spring-loaded contactor system. The elastic contactor automatically maintains electrical connection through elastic force, eliminating the need for nuts and threaded fasteners. This mechanical substitution enables tool-free assembly and disassembly while ensuring reliable electrical connection.
Solution Approach 2:
The elastic contactor is designed to self-adjust and self-maintain the electrical connection. When the battery module is inserted, the elastic contactor automatically compresses and makes contact with the electrode terminal, maintaining constant pressure without requiring external fastening operations. This self-service mechanism simplifies assembly while ensuring connection reliability.
2Reliability
If multiple battery modules are connected using nut fastening, then electrical connection is established, but maintenance and reassembly become complex
Solution Approach 1:
The spring-loaded contactor system replaces complex nut fastening mechanisms with a simple elastic contact system. This substitution allows battery modules to be easily removed and reinstalled for maintenance without requiring tools or complex disassembly procedures, while the elastic contactor continuously maintains stable electrical connection during operation.
3Ease of manufacture
If traditional bus bar connection methods are used, then electrical connection is achieved, but connection defects like loose connections may occur
Solution Approach 1:
The patent changes the connection parameter from static (nut fastening with fixed clamping force) to dynamic (spring-loaded contactor with automatic force adjustment). The elastic contactor continuously adapts to dimensional variations and settling effects, maintaining optimal contact pressure throughout the product lifecycle, thereby preventing loose connections and contact defects.
