Replaceable Battery Case Lid Lock Feedback During EV Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery electric vehicles face issues with battery pack handling due to locked doors preventing loading and unloading, leading to operational difficulties when the door is locked inappropriately during battery replacement.
Innovation Solution
Incorporating a lock device that locks the battery case lid when not openable and a notification device to inform operators of the locked state, allowing appropriate measures such as waiting or requesting repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the open and close door is locked so as not to be openable when battery packs are supposed to be unloaded and loaded, then the battery packs are unable to be unloaded and loaded, but the battery packs are protected and contact is avoided
Solution Approach 1:
The notification device provides feedback to the operator about the locked state of the door, enabling the operator to understand why the door cannot be opened and take appropriate actions such as waiting for unlocking or requesting repair, thus resolving the contradiction between protection and operability
2Reliability
If the open and close door is locked to protect battery packs, then contact with battery packs is avoided, but operators cannot take appropriate measures when locking occurs during battery replacement
Solution Approach 1:
The notification device provides feedback information about the locked state to the operator, eliminating the information loss and enabling the operator to make informed decisions about whether to wait for automatic unlocking or request repair services
