Solution Overview
Problem
Existing battery cell testing systems face challenges in ensuring reliable and accurate charging and discharging processes due to errors in component assembly and disassembly, particularly in large electronic appliances that require high output and capacity, which can lead to inconsistent test results.
Innovation Solution
A charging/discharging system is developed with an integrated structure combining a power unit, chamber, air conditioning unit, and interface unit, along with a jig system that securely holds battery cells and adjusts temperature and humidity, reducing errors through precise control and minimizing cable length to reduce voltage drop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery cells are tested using separate components that require assembling and disassembling, then the testing system can be flexible and easy to manufacture, but errors are generated during assembly and disassembly that reduce test reliability
Solution Approach 1:
The patent combines the charging/discharging power unit, chamber, air conditioning unit, and interface unit into a single integrated structure. This merging eliminates the need for separate assembly and disassembly of components during testing, thereby reducing errors and improving test reliability while maintaining controlled testing conditions.
2Measurement precision
If cable length is increased to connect components, then the system can accommodate larger battery cells and provide easier access, but voltage drop increases which affects measurement precision
Solution Approach 1:
By integrating the power unit and chamber into a single structure with minimal cable connections, the patent reduces cable length to a minimum necessary for operation. This minimization of cable length reduces voltage drop and improves voltage measurement accuracy while still providing adequate access to battery cells through the integrated chamber design.
3Area of stationary object
If multiple separate units are used for charging/discharging, temperature control, and interface, then each unit can be optimized independently, but the overall system occupies more space and generates higher operational loads
Solution Approach 1:
The patent integrates four distinct functional units (charging/discharging power unit, chamber, air conditioning unit, and interface unit) into a single compact structure. This merging reduces the overall system footprint and operational loads while maintaining the functional versatility of each unit through modular internal design that allows independent optimization of each subsystem.
