Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintainability of electrical and electronic parts in high voltage battery systems for electric vehicles, such as electric buses, is difficult due to lack of consideration in design, leading to challenges in maintenance and installation.
Innovation Solution
A high voltage battery carrier system that modularizes the high voltage battery and electrical and electronic parts on a frame, using a main carrier, subcarrier, and detachable carrier configuration, allowing for easy access and maintenance by separating the detachable carrier from the subcarrier, thereby improving workability and maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical and electronic parts are integrated into the high voltage battery system, then the system functionality is improved, but the maintainability deteriorates
Solution Approach 1:
The battery system is divided into multiple battery modules, each with its own electronic control unit. This segmentation allows individual modules to be maintained or replaced independently, improving maintainability while preserving overall system functionality. The electronic parts are distributed across modules rather than centralized, enabling localized maintenance.
2Quantity of substance
If multiple high voltage batteries and electrical parts are provided in large vehicles, then the energy capacity is improved, but the installation space requirement increases
Solution Approach 1:
Electronic control units and electrical parts are integrated within the battery modules themselves, nesting components within each other to reduce overall installation space. The electronic parts are housed inside the battery module enclosures, eliminating the need for separate dedicated spaces for each component while maintaining full energy capacity.
3Stability of the object's composition
If electrical and electronic parts are fixed in place for structural stability, then the system stability is improved, but the workability deteriorates
Solution Approach 1:
The battery modules are designed with dynamic characteristics, allowing them to be easily assembled and disassembled during installation and maintenance while maintaining structural stability during operation. The modules use reversible connection mechanisms that provide stability when connected but enable easy separation when needed, resolving the contradiction between fixed stability and operational flexibility.

AI summary
A high voltage battery carrier for a vehicle includes: a main carrier coupled to a vehicle body frame and fixed to a high voltage battery; a subcarrier coupled to an upper portion or a lower portion of the main carrier and configured to form a space in which an electrical and electronic part is accommodated when coupled to the main carrier; and a detachable carrier which is vertically detachably installed on the subcarrier. The electrical and electronic part is coupled to the detachable carrier. With this arrangement, installation space can be reduced and workability is improved due to easy attachment and detachment of the electrical and electronic part.
