EV Battery Mount Alignment Using Position and Orientation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery replacement systems face challenges in reliably attaching batteries to electric vehicles due to inconsistent battery mount positions and orientations, making it difficult to secure a stable connection.
Innovation Solution
A battery replacement apparatus and method that includes a detector to identify the position and orientation of the first battery, a raisable battery mount, and an adjuster to adjust the position and orientation of the second battery based on the detected data, ensuring accurate alignment and attachment to the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the battery mount position is adjusted based on laser range finder detection, then the battery can be positioned for attachment, but the inconsistent battery position on the mount makes reliable attachment difficult
Solution Approach 1:
The system uses a detector to detect the position and orientation of the first battery, then feeds this information back to the adjuster which automatically adjusts the second battery's position and orientation to match, creating a closed-loop feedback system that ensures reliable attachment despite variations in battery mount position
Solution Approach 2:
The adjuster automatically adjusts the second battery's position and orientation based on detector feedback without requiring manual intervention, allowing the system to self-correct for position variations and achieve reliable attachment autonomously
2Ease of operation
If the battery mount is raised to attach the battery from below, then attachment is enabled, but position and orientation variations prevent stable connection
Solution Approach 1:
The system makes the battery position and orientation dynamic and adjustable through the adjuster mechanism, allowing real-time adaptation to match the vehicle body's requirements rather than requiring fixed precision in the battery mount position
Solution Approach 2:
The adjuster changes the position and orientation parameters of the second battery based on detector feedback, enabling the system to compensate for mount variations and achieve precise alignment for stable connection

AI summary
A battery replacement apparatus includes a detection device that detects position and orientation of a battery (first battery), a battery mount where a battery (second battery) is placed, the battery mount being capable of being raised, and an adjuster that adjusts position and orientation of the battery that is placed on the battery mount. The battery mount allows the battery to be attached to a vehicle body from below the vehicle body, by being raised below the vehicle body in a state where the battery is placed on the battery mount. The adjuster adjusts the position and the orientation of the battery placed on the battery mount, based on the position and the orientation of the battery detected by the detection device.
