Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The edge beam of the tray in battery packs is prone to deformation during collisions, leading to potential battery short circuits and safety hazards due to extrusion of battery poles.
Innovation Solution
A battery pack design incorporating a temperature equalisation plate with first edge portions that fit into clamping slots on the tray's edge beams, enhancing structural strength and preventing deformation, coupled with cooling tubes and heaters for temperature management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery pack is detachably mounted to a vehicle body, then ease of replacement and charging is improved, but connection reliability and contact stability deteriorate due to repeated connection/disconnection
Solution Approach 1:
The battery pack is designed as a separable module that can be detached from the vehicle body, allowing independent replacement of the battery pack without affecting the vehicle structure. This segmentation enables easy removal and installation while maintaining connection reliability through dedicated connection interfaces.
Solution Approach 2:
Connection terminals are pre-provided on both the battery pack and vehicle body before actual connection occurs. These pre-positioned terminals ensure that when the battery pack is mounted, electrical connection is immediately established without requiring additional assembly steps, thereby maintaining high connection reliability despite repeated detachable operations.
2Use of energy by moving object
If battery capacity is increased to extend driving range, then energy storage is improved, but battery pack size and weight increase
Solution Approach 1:
The battery pack is designed with adjustable parameters including capacity, voltage, and physical dimensions. This allows optimization of the battery pack specifications to achieve the required driving range while minimizing weight and size, adapting to different vehicle requirements without fixed constraints.
Solution Approach 2:
The battery pack can be configured in different arrangement patterns (series/parallel connections) and physical layouts to achieve the desired energy storage capacity. By changing the dimensional arrangement rather than simply increasing individual cell size, the system achieves higher capacity while controlling overall pack weight and dimensions.
3Volume of moving object
If battery pack dimensions are reduced for compact vehicle integration, then space utilization is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The battery pack is divided into multiple battery modules, each with its own thermal management capabilities. This segmentation allows heat to be dissipated from multiple distributed points rather than requiring the entire pack to be large for heat dissipation, enabling compact overall dimensions while maintaining effective thermal management.
Solution Approach 2:
A connection terminal structure is provided that serves as an intermediary between battery modules and the vehicle body. This terminal structure includes thermal management functions, acting as a heat dissipation pathway that enables effective thermal control in compact battery pack configurations without requiring additional dedicated cooling components.
