Working Vehicle Battery Pack With Hinged Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs for working vehicles, such as construction machines, require cumbersome maintenance procedures as the electric components are housed within a sealed space, making it difficult to access and maintain without removing the entire pack from the vehicle.
Innovation Solution
A battery pack design with an electric component housing chamber featuring an opening portion and a maintenance cover hinged to the housing, allowing access to electric components without removing the pack from the vehicle, and positioning the cover higher than the lower end of the battery cover opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery pack uses a sealed housing to protect electric components, then the reliability and protection of electric components is improved, but the ease of maintenance deteriorates as access requires removing the entire battery pack from the vehicle
Solution Approach 1:
The housing is segmented into a main body and a separate maintenance cover that can be opened independently. The maintenance cover is hinged to the housing and can be opened to provide access to the electric component housing chamber without removing the entire battery pack from the vehicle, thus maintaining protection while enabling easy maintenance access
Solution Approach 2:
The maintenance function is extracted from the main battery pack structure by providing a separate, independently openable maintenance cover. This allows the maintenance operation to be separated from the entire battery pack removal operation, enabling access to electric components while the battery pack remains mounted on the vehicle
2Object-affected harmful factors
If the battery pack is designed as a sealed unit, then the protection against foreign substances and temperature uniformity is improved, but the maintenance operation becomes cumbersome requiring removal from the vehicle
Solution Approach 1:
The sealed housing is segmented by introducing a hinged maintenance cover that can be opened independently. This segmentation allows the maintenance cover to be opened for access to electric components while the rest of the housing maintains its sealed structure to protect against foreign substances and maintain temperature uniformity
Solution Approach 2:
The maintenance cover is designed as a dynamic, movable component that can be opened and closed as needed for maintenance operations. This dynamic element allows the housing to transition between a fully sealed state for protection and an open state for maintenance, without compromising the overall sealed structure

AI summary
Provided is a battery pack that is used in a working vehicle where an operator can easily get access to an electric component housing chamber in which an electric component is housed thus enhancing the maintenance property of the electric component. The battery pack includes a battery module, electric components, and a housing that houses the battery module and the electric components. The housing includes an electric component housing chamber that houses the electric components. The electric component housing chamber includes: an opening portion that enables an operator to get access to the electric component housing chamber from the outside; and a maintenance cover that is configured to be capable of closing the opening portion. The maintenance cover is mounted on the housing by a hinge.
