Solution Overview
Problem
Existing battery housing designs for high-voltage batteries in motor vehicles face challenges in simplifying installation and maintenance, ensuring safe and low-vibration fixation, and achieving accurate temperature monitoring, while also complicating the structure and increasing the number of components that need to be combined.
Innovation Solution
A battery housing composed of six combinable components, including four plate-shaped side panels and two cover plates, with elongated recesses for a functional cooling plate that serves as both a heat dissipation and stabilizing component, allowing for self-supporting structure and accessible installation and maintenance, and featuring independent countercurrent cooling circuits and gas discharge openings for enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If accurate determination of physical features of battery cells during operation is implemented, then temperature monitoring is improved, but the structure becomes more complex
Solution Approach 1:
The patent introduces cooling plates as intermediary components that directly contact the battery cells and provide integrated temperature monitoring. These cooling plates serve as both thermal management devices and measurement interfaces, simplifying the overall structure while enabling accurate temperature determination
2Reliability
If safe and low-vibration fixation of individual battery cells is ensured, then the life and durability of the battery is improved, but the number of components that need to be combined increases
Solution Approach 1:
The patent combines multiple functions into integrated components. The side panels combine structural support, cooling plate mounting, and cell fixation functions. The base plate integrates positioning and support functions. This merging reduces the total number of separate components while ensuring safe and stable cell fixation that minimizes vibrations
Solution Approach 2:
The patent applies different structural characteristics to different parts of the battery housing. The side panels use elongated recesses for flexible cooling plate installation, while the base plate provides rigid positioning features. This localized optimization ensures proper fixation and durability without requiring complex structures throughout the entire housing
3Reliability
If the battery housing allows installation and maintenance work accessible from top and bottom, then safety during high-voltage operations is improved, but the housing structure becomes more complex
Solution Approach 1:
The battery housing is segmented into removable side panels and cover plates that can be independently accessed from top and bottom. This segmentation allows maintenance workers to safely access different parts of the battery from multiple directions without disassembling the entire housing, improving safety during high-voltage operations
Solution Approach 2:
The side panels serve as both structural components and access points for maintenance. The base plate provides both support and bottom access. This multi-functionality allows the housing to maintain structural integrity while enabling safe top and bottom access for installation and maintenance work

AI summary
A battery housing and a method for installing a battery are disclosed. In one embodiment, a battery housing for receiving a battery includes four plate-shaped side panels. Two of the side panel are opposite to each other, and each of the two opposite side panels have at least one elongated recess. The battery housing includes two cover plates. The four plate-shaped side panels and the two cover plates are connected to each other to form a box-shaped housing. The side panels are configured to connect together to hold the battery without the cover plates.
