Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transport packaging (cartons, wooden cases, metal cases) is used for power lithium ion batteries, then the packaging structure is simple and easy to manufacture, but the protective performance is insufficient and real-time monitoring capabilities are lacking
Solution Approach 1:
The patent combines multiple monitoring functions (temperature, gas detection, smoke detection, pressure sensing) into an integrated monitoring system within the transport packaging. This merging of multiple subsystems enhances protective performance while managing complexity through unified design and centralized data processing.
Solution Approach 2:
The monitoring system is designed to perform multiple functions simultaneously: temperature monitoring, gas composition analysis, smoke detection, and pressure sensing. This multi-functionality approach allows a single packaging system to address various thermal runaway indicators, improving reliability without requiring separate specialized packages for each function.
2Loss of information
If traditional transport packaging without monitoring functions is used, then the device complexity is low and manufacturing is simple, but real-time monitoring and early warning capabilities are absent
Solution Approach 1:
The system incorporates sensors and monitoring equipment in advance within the packaging structure, enabling real-time detection of thermal runaway indicators before actual thermal runaway occurs. This preliminary action allows early warning and preventive measures to be taken, capturing critical information about battery status during transport.
Solution Approach 2:
The patent introduces a data processing unit and communication module as intermediaries between the sensors and the external monitoring system. These intermediaries process sensor data, filter relevant information, and transmit warnings to external systems, enabling real-time monitoring capability while managing system complexity through layered architecture.
3Measurement precision
If multiple sensors (temperature, gas, smoke, pressure) are integrated into the monitoring system, then thermal runaway detection accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The monitoring system is segmented into distinct functional modules: temperature sensing unit, gas detection unit, smoke detection unit, and pressure sensing unit. Each module independently monitors specific thermal runaway indicators, and their data is integrated by the data processing unit. This segmentation allows precise multi-parameter monitoring while managing complexity through modular design and independent functionality.

AI summary
The present invention discloses a thermal runaway monitoring and early warning system and method for a power lithium ion battery in a transport case.

The data transmission unit sends early warning information to a terminal. According to a multi-information monitoring-based thermal runaway early warning method under different transport conditions, different transport condition data and data of the battery in the transport case are fused. A clustering algorithm and an ensemble learning algorithm are involved, and a lithium ion battery thermal runaway risk level is quantified, thereby improving the early warning accuracy.
