EV Battery Mount Alignment Using Position and Orientation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery replacement systems for electric vehicles face challenges in accurately positioning and orienting removed batteries on battery mounts, especially when the battery's position and orientation shift from their predetermined states.
Innovation Solution
A battery replacement apparatus equipped with detectors to assess the position and orientation of the removed battery, a controller to adjust the battery mount's position and orientation accordingly, and a system that includes a vehicle holding unit to maintain the electric vehicle horizontally, ensuring precise alignment and simplifying the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery position and orientation are not precisely controlled during removal, then the battery replacement process is simpler, but the battery cannot be reliably placed on the battery mount
Solution Approach 1:
The system performs preliminary detection of the battery's position and orientation using detectors before the removal operation. The controller then calculates the appropriate battery mount position and orientation in advance, and adjusts the mount accordingly before the battery is removed, ensuring reliable placement without requiring complex real-time control during removal
Solution Approach 2:
The system uses detectors to detect the actual position and orientation of the battery, feeds this information back to the controller, which then adjusts the battery mount's position and orientation accordingly. This closed-loop feedback mechanism ensures the battery is reliably placed on the mount while managing system complexity through automated control
2Reliability
If the battery mount is made movable and adjustable, then the battery can be reliably placed on the mount, but the device complexity increases
Solution Approach 1:
The battery mount is designed with movable and adjustable capabilities, allowing it to change position and orientation dynamically based on the detected battery parameters. The controller autonomously adjusts the mount's degree of freedom to match the battery's actual position and orientation, ensuring reliable placement while maintaining operational simplicity
Solution Approach 2:
The system changes the positional and orientational parameters of the battery mount based on detected battery parameters. The controller adjusts the mount's position and orientation parameters to correspond with the battery's actual state, enabling reliable placement without requiring complex manual intervention

AI summary
A battery replacement apparatus includes a detection device (detector) that detects position and orientation of a battery (first battery), a battery mount where the battery that is removed from an electric vehicle is placed, the battery mount being driven below the electric vehicle, and a processor (controller) that controls driving of the battery mount. The processor controls position and orientation of the battery mount based on the position and the orientation of the battery detected by the detection device. Furthermore, the processor performs control of removing the battery from the electric vehicle, in a state where the position and the orientation of the battery mount are controlled.
