Battery Locking Control for Precise EV Battery Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery locking/unlocking methods for electric vehicle battery swapping systems fail to accurately control the strokes of battery swapping devices, leading to errors and reduced swapping speed and success rates.
Innovation Solution
A battery locking/unlocking system with lock shafts, lock slots, and lock tongues, along with detection and control units, ensures precise location and locking/unlocking through location signals and instructions, using sensors and a data exchange unit to adjust the battery's position and control the lock tongues for accurate engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing battery locking/unlocking methods are used, then the battery swapping process can be completed, but the strokes of battery swapping device cannot be accurately controlled, leading to errors and reduced swapping speed and success rate
Solution Approach 1:
The patent implements a feedback mechanism where the lock shaft detection unit continuously monitors the position of lock shafts and sends location signals to the data exchange unit, which then transmits them to the battery swapping device. The device adjusts its position based on this feedback, creating a closed-loop control system that ensures accurate positioning and improves swapping reliability
Solution Approach 2:
The patent replaces traditional mechanical positioning and detection systems with an automated detection and control system. The lock shaft detection unit uses sensors (not purely mechanical contact) to detect lock shaft positions, and the battery swapping device uses electronic control based on location signals to adjust its position, substituting mechanical trial-and-error with precision electronic control
2Productivity
If existing battery locking/unlocking methods are used, then the battery swapping process can be completed, but the swapping speed is reduced due to errors and lack of accurate control
Solution Approach 1:
The patent performs preliminary detection of lock shaft positions using the lock shaft detection unit before the actual locking operation. The detection unit identifies the precise location of lock shafts in advance, allowing the battery swapping device to pre-position itself accurately, thereby preventing errors during the swapping process and improving overall speed
Solution Approach 2:
The continuous feedback loop where location signals are transmitted from the detection unit to the battery swapping device enables real-time position adjustments. This ensures that the device can quickly and accurately locate the correct position without repeated attempts, thereby increasing swapping speed while maintaining precision

AI summary
Provided are a battery locking/unlocking system, and an electric vehicle battery swapping control system and a control method thereof. The battery locking/unlocking system comprises a battery swapping device used for moving a battery; a lock shaft detection unit used for generating a location signal; a lock tongue control unit used for controlling a lock tongue to fall into the lock slot or retract to the outside of the lock slot; a data exchange unit separately communicates with the battery swapping device and the lock shaft detection unit. According to the battery locking/unlocking system and locking and unlocking control methods, 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, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.
