1Duration of action of moving object
If multiple battery trailers are connected to an electrified vehicle, then the operational period of the electrified vehicle is extended, but the complexity of connection status detection increases
Solution Approach 1:
The connection status detection system is segmented into multiple independent detection units, with each unit responsible for detecting the connection status of a specific battery trailer. This segmentation allows the system to scale to multiple trailers without requiring a completely new detection architecture, thereby extending operational period while managing detection complexity through modular design.
Solution Approach 2:
The detection units are designed with universal functionality to handle various connection scenarios (single trailer, multiple trailers, different connection configurations). Each detection unit can independently detect connection status across different trailer configurations, eliminating the need for specialized detection systems for each scenario and reducing overall system complexity.
2Power
If multiple battery trailers are connected to an electrified vehicle, then the power supply capacity is increased, but the reliability of connection status management decreases
Solution Approach 1:
The determination unit receives real-time connection status information from multiple detection units and continuously monitors the overall connection status. This feedback mechanism ensures that the system can reliably manage connection states across multiple battery trailers, maintaining connection integrity even as power supply capacity increases through additional trailers.
Solution Approach 2:
The determination unit acts as an intermediary that consolidates information from multiple detection units and makes overall connection status determinations. This intermediary layer simplifies the management complexity by centralizing the decision-making process for connection status, thereby maintaining reliability as the number of connected trailers increases.
3Measurement precision
If connection status detection is implemented for each terminal, then the precision of connection detection is improved, but the device complexity increases
Solution Approach 1:
Multiple detection units that each monitor specific terminals are merged into a unified determination unit that consolidates all connection status information. This merging approach maintains high detection precision by preserving individual terminal monitoring capabilities while reducing overall device complexity through centralized processing and unified connection status determination.
