Climate Control Power Distribution With Fault Isolation for EV Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric vehicles and transport containers, faults in electrical systems or energy storage components often lead to complete shutdowns, disrupting critical and safety systems, and there is a need to isolate faulty components to maintain partial system operation, especially during transport.
Innovation Solution
A power management system that monitors fault reports and controls power distribution by isolating faulty sub-systems, allowing non-faulted systems to continue operating and enabling partial power connections through alternate battery module connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fault monitoring and isolation systems are implemented, then system reliability is improved, but device complexity increases
Solution Approach 1:
The electrical system is divided into modular sub-systems with individual fault detection and isolation capabilities. Each sub-system can be independently monitored and isolated, allowing the rest of the system to continue operating. This segmentation approach improves reliability by containing faults locally while managing complexity through standardized modular interfaces.
Solution Approach 2:
A power controller acts as an intermediary between power sources and power users, monitoring fault conditions and managing power distribution. This intermediary component centralizes fault management functions, improving system reliability through coordinated response while preventing complexity from propagating throughout the entire system.
2Object-affected harmful factors
If complete system shutdown occurs upon fault detection, then safety is improved, but productivity is worsened
Solution Approach 1:
The faulty sub-system is extracted or isolated from the overall system through controlled disconnection. This allows the harmful effects of the fault to be contained and eliminated while preserving the operation of non-faulted systems, thereby maintaining productivity during critical transport operations.
Solution Approach 2:
The system transitions from a static all-or-nothing operation mode to a dynamic state where individual sub-systems can be independently controlled. When faults are detected, the system dynamically adjusts by isolating affected components while maintaining power flow to critical systems, balancing safety requirements with operational continuity.
3Adaptability or versatility
If multiple power sources are integrated, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power controller is designed with multi-functional capabilities to manage multiple power sources and various fault conditions through a single integrated device. This universal approach improves adaptability by handling diverse power configurations while preventing complexity multiplication by consolidating control functions in one component.
