Vehicle-Integrated HV Battery Housing With Connection Field Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating high-voltage accumulators on motor vehicles do not facilitate a particularly advantageous fluidic and electrical connection, often requiring separate housings and complex assembly processes.
Innovation Solution
A method and arrangement where battery modules are fastened to a base plate of the vehicle's support structure, with connection fields mechanically attached to provide both electrical and fluidic connections, allowing the accumulator to be integrated into the vehicle's body without a separate housing, and utilizing sealing and screw connections for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a separate housing is used for the high-voltage accumulator, then the accumulator modules are protected and easily assembled, but the overall weight increases and space is consumed
Solution Approach 1:
The patent merges the housing function with the vehicle's support structure by integrating the accumulator housing into the vehicle body's floor structure. The base plate serves dual purposes as both a structural component of the vehicle body and as the housing for the accumulator modules, eliminating the need for a separate housing structure.
Solution Approach 2:
The support structure of the vehicle body is given multiple functions: it provides structural support for the vehicle and simultaneously serves as the housing for the high-voltage accumulator. This multi-functional design reduces overall system weight and complexity by eliminating redundant structures.
2Ease of operation
If connection fields are integrated into the support structure, then electrical and fluidic connections are simplified, but the mechanical connection complexity increases
Solution Approach 1:
The connection fields are merged with the support structure by integrating electrical and fluidic connection elements directly into the vehicle body structure. This allows connection lines to be routed through the support structure itself, simplifying the overall connection system while distributing the mechanical complexity across existing structural components.
3Ease of manufacture
If the accumulator housing is formed by base plate and bottom plate, then manufacturing is simplified and weight is reduced, but sealing and protection requirements become more critical
Solution Approach 1:
The housing is formed by merging the base plate and bottom plate into a unified structural assembly that is integrated with the vehicle body. This simplified housing design relies on the structural integrity and sealing capabilities of the vehicle's existing floor structure, reducing manufacturing complexity while maintaining reliability through the vehicle's proven structural design.

AI summary
A method is provided for arranging a high-voltage accumulator having a plurality of battery modules on a support structure of a motor vehicle, in which the battery modules are arranged and fastened on a base plate, and the base plate is fastened on a bottom plate of the support structure of the motor vehicle, as a result of which the base plate and the bottom plate provide an accumulator housing which delimits an accumulator interior in which the battery modules are accommodated. At least one connection field is mechanically connected to the support structure. The connection field is able to electrically and/or fluidically connect the high-voltage accumulator to the motor vehicle.
