Battery Probe Set Replacement for Continuous Capacity Grading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing formation capacity-grading apparatuses for lithium-ion batteries require shutting down the entire device for probe replacement, leading to poor operating efficiency due to the need for manual disassembly and reassembly.
Innovation Solution
A formation capacity-grading apparatus with a probe assembly, a support apparatus, and an adjustable pressing platform, allowing for the automatic separation and replacement of probe sets without shutting down the entire apparatus, utilizing a support apparatus that can adjust to support the probe assembly and facilitate the replacement of probe sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire apparatus is shut down for probe replacement, then the probe can be safely replaced, but the operating efficiency deteriorates due to logistics line stoppage
Solution Approach 1:
The probe assembly is segmented into multiple independent probe sets (first probe set, second probe set, etc.) that can be independently replaced. The support apparatus is also segmented with separate support positions for different probe sets, allowing one probe set to be replaced while others continue operating, thus resolving the contradiction between safe replacement and continuous operation
Solution Approach 2:
The support apparatus is pre-configured with multiple support positions and can switch between them. Before replacing a probe set, the system can preliminarily position the support apparatus at a different support position, enabling seamless transition and continuous operation during probe replacement, thereby maintaining productivity while ensuring replacement safety
2Ease of manufacture
If manual disassembly and reassembly is performed, then probe replacement is achieved, but the complexity of operation increases and time is lost
Solution Approach 1:
The support apparatus is designed to automatically support and position the probe assembly during replacement. The pressing platform automatically adjusts to maintain proper contact pressure, and the support apparatus can automatically switch between support positions, reducing the need for manual disassembly and reassembly operations, thus improving ease of operation
Solution Approach 2:
The pressing platform is designed with adjustable height capability, allowing it to dynamically adapt to different probe set positions during replacement. The support apparatus can also dynamically switch between fixed support positions, making the replacement process more flexible and easier to operate without manual intervention
3Reliability
If contact resistance is monitored in real-time, then defective batteries can be prevented, but the device complexity increases due to additional monitoring systems
Solution Approach 1:
The existing detection装置 in the formation capacity-grading apparatus is designed to perform multiple functions: it not only detects battery capacity during formation but also monitors contact resistance of probe sets in real-time. This multi-functional approach allows defective battery prevention without adding separate monitoring systems, thus resolving the contradiction between reliability improvement and device complexity
