Battery Swap Locking Control With Lock Shaft Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery locking/unlocking methods for electric vehicle battery swapping fail to accurately control the strokes of the battery swapping device and the battery, leading to errors and reduced swapping speed and success rate.
Innovation Solution
A battery locking/unlocking system that includes a battery swapping device, a lock shaft detection unit, a lock tongue control unit, and a data exchange unit, which work together to accurately detect the location of lock shafts, control the lock tongues, and adjust the battery position for precise locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery locking/unlocking method is used without accurate stroke control, then the swapping process can proceed, but errors appear during battery swapping affecting speed and success rate
Solution Approach 1:
The patent employs a feedback mechanism where the lock shaft detection unit continuously monitors the position of lock shafts during the swapping process. The data exchange unit transmits position information between the detection unit and battery swapping device, enabling real-time adjustments to maintain accurate strokes and prevent errors, thus improving both reliability and productivity
Solution Approach 2:
The patent replaces traditional mechanical stroke control with an automated detection and control system. The lock shaft detection unit uses sensors to detect lock shaft positions, and the battery swapping device automatically adjusts its strokes based on this data, eliminating manual or purely mechanical control methods that caused errors
2Manufacturing precision
If the battery swapping device operates without real-time location detection, then the system structure remains simple, but accurate control of battery strokes cannot be achieved
Solution Approach 1:
The patent divides the locking/unlocking system into distinct functional modules: the lock shaft detection unit for position detection, the data exchange unit for information transmission, and the battery swapping device for execution. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and precision
Solution Approach 2:
The data exchange unit serves as an intermediary between the lock shaft detection unit and the battery swapping device. It facilitates accurate communication of position information, enabling precise stroke control without requiring direct complex integration between the detection and execution components

AI summary
Disclosed is a battery unlocking control method, a battery locking control method and an electric vehicle battery swapping control method. The battery locking control method comprises the following steps: moving the battery to the fixing base to enable the lock shafts to enter the lock slots; after the lock shafts enter the lock slots, detecting the locations of the lock shafts, and moving the battery until the lock shafts arrive at locking locations; and with the lock tongues falling, snapping the lock shafts into the lock slots. By providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed from the fixing base, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.
