Battery Fastener Cleansing for Easier EV Battery Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery electric vehicles, foreign matter adhesion to fastening portions can prevent tools from fitting, making it difficult to remove batteries from the vehicle body.
Innovation Solution
A vehicle equipped with a cleansing unit that includes a spray unit and a supply unit to clean the fastening members, allowing tools to effectively fit and remove the battery by spraying a cleansing fluid and using a pump to move the spray unit between spraying and stored positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fastening members are used to secure the battery to the vehicle body, then the battery is firmly fixed, but foreign matter adhesion prevents tools from fitting to the fastening members
Solution Approach 1:
The cleansing unit performs preliminary cleaning of the fastening members before battery removal operations. The spray nozzle sprays cleansing fluid onto the fastening members to remove foreign matter such as ice or snow, ensuring that tools can subsequently fit properly to the fastening members for battery removal.
2Reliability
If the vehicle operates in cold environments, then the battery must remain secured, but foreign matter accumulates on fastening portions
Solution Approach 1:
The cleansing unit acts as an intermediary between the fastening members and foreign matter. It includes a spray nozzle that sprays cleansing fluid onto the fastening members and a collection tray that collects the sprayed fluid and removed foreign matter, preventing foreign matter accumulation while maintaining battery securing reliability.
3Ease of operation
If a cleansing unit is added to remove foreign matter, then tool accessibility is improved, but device complexity increases
Solution Approach 1:
The cleansing unit is designed with multi-functionality to reduce overall system complexity. The spray nozzle serves both to clean the fastening members and to suppress ice formation. The collection tray both collects spent fluid and prevents ice accumulation on vehicle components, achieving multiple functions with a relatively simple structure.
