EV Charger Movement Monitoring for Shipping Damage Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately monitor and record adverse situations, such as dents, scratches, or component breakage, that an electric vehicle charger may encounter during shipping and installation, making it difficult to determine the responsible party and plan remedial actions.
Innovation Solution
The electric vehicle charger is equipped with a detection unit, such as an accelerometer, to measure nonconforming movements and determine optimal movement thresholds based on its state. It powers up a telematics control unit and geolocation unit to record and transmit details of adverse situations, enabling transparent identification of responsible parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If no monitoring system is installed on the charger, then the device complexity is low, but the ability to detect and measure adverse situations is insufficient
Solution Approach 1:
The patent applies preliminary action by installing the detection unit, telematics control unit, and geolocation unit on the charger before shipping. These components are pre-configured to automatically monitor and record adverse situations during transit and installation, eliminating the need for post-incident investigation while maintaining manageable device complexity through integrated design.
2Reliability
If a comprehensive monitoring system is implemented, then the reliability of adverse situation recording is improved, but the loss of energy increases due to continuous monitoring operations
Solution Approach 1:
The patent implements periodic action by having the detection unit and telematics control unit activate only when adverse situations occur, rather than continuous monitoring. The system uses motion sensors and impact detectors to trigger recording operations, significantly reducing energy consumption while maintaining reliable documentation of actual adverse events during shipping and installation.
3Loss of information
If detailed monitoring data is collected and transmitted, then the loss of information is reduced, but the device complexity and data management requirements increase
Solution Approach 1:
The patent applies the extraction principle by isolating the data management complexity into separate modular components: the detection unit collects sensor data, the telematics control unit processes and filters information, and the geolocation unit tracks position. This modular architecture reduces overall system complexity while ensuring complete adverse situation information is captured and transmitted to relevant parties.

AI summary
A system including a detection unit and a processor is disclosed. The detection unit may be configured to measure a level of nonconforming movement associated with the system. The processor may be configured to determine a system installation state from a plurality of system installation states, and identify an optimal movement threshold, from a plurality of movement thresholds associated with the plurality of system installation states, based on the system installation state. The system may further determine that the level of nonconforming movement may be greater than the optimal movement threshold, and perform a predefined action responsive to determining that the level of nonconforming movement may be greater than the optimal movement threshold.
