Battery Swapping Positioning Using Lock-Base Image Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery swapping equipment for electric vehicles lacks closed-loop control, leading to potential positioning inaccuracies and battery swapping failures.
Innovation Solution
Incorporation of an image collection module to capture actual images of the lock base and lock linkage during unlocking and locking processes, with a positioning judgement module to compare these images to standard images for precise alignment and confirmation, and a moving mechanism to adjust positioning as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery swapping equipment is deployed in uncoordinated locations, then market expansion and service coverage are improved, but resource waste and operational inefficiency increase
Solution Approach 1:
The system implements real-time data collection and analysis of battery demand patterns, vehicle traffic flow, and charging requirements at various locations. This feedback mechanism enables dynamic adjustment of battery swapping station locations and operations, ensuring resources are deployed where actually needed rather than through static planning, thereby reducing resource waste while maintaining broad service coverage
Solution Approach 2:
The system performs preliminary analysis of battery demand and vehicle flow patterns before deploying swapping stations. By predicting future battery needs and vehicle routes in advance, the system can pre-position swapping equipment in optimal locations, avoiding both over-deployment (resource waste) and under-deployment (insufficient coverage)
2Ease of operation
If battery swapping equipment operates without precise positioning, then operational flexibility is maintained, but battery matching accuracy and swapping efficiency deteriorate
Solution Approach 1:
The system replaces manual positioning and matching operations with automated GPS-based location tracking and RFID-based battery identification. This substitution maintains operational flexibility for staff while achieving high precision in battery matching through electronic positioning and recognition systems, eliminating the need for manual measurement and matching processes
3Device complexity
If manual battery matching and positioning methods are used, then equipment complexity is reduced, but productivity and swapping speed decrease
Solution Approach 1:
The system implements automated battery identification, positioning, and matching functions that operate autonomously without requiring complex manual intervention. The GPS tracking and RFID recognition systems automatically identify batteries and vehicles, enabling rapid swapping operations while keeping the overall system architecture relatively simple and easy to operate
Solution Approach 2:
The positioning and identification system serves multiple functions simultaneously: it tracks vehicle locations, identifies battery types, monitors inventory levels, and optimizes swapping routes. This multi-functionality increases productivity across all operations without proportionally increasing equipment complexity, as a single integrated system performs multiple tasks

AI summary
The present disclosure discloses battery swapping equipment for an electric vehicle and a positioning method for battery swapping equipment. The battery swapping equipment includes: an unlocking mechanism configured to unlock a battery pack locked onto a fast swapping bracket of the electric vehicle; an image collection module configured to collect a first actual image comprising the lock base during an unlocking process of the battery pack; a storage module configured to store a first standard image collected by the image collection module when the battery swapping equipment is located in a battery swapping position, the first standard image comprising the lock base; a positioning judgement module configured to judge whether the battery swapping equipment is located in the battery swapping position according to the first actual image and the first standard image; if not, generating a first moving instruction according to a judged result; a moving mechanism configured to move according to the first moving instruction. The battery swapping equipment may generate, according to the above actual image and standard image, a moving instruction for controlling the moving mechanism to move, until the battery swapping equipment moves into a battery swapping position, thus achieving closed-loop control for the positioning of the battery swapping equipment.
