Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional battery systems are used in electric vehicles, then the vehicle can operate with a single battery source, but the system lacks fault tolerance and reliability when battery failures occur
Solution Approach 1:
The battery system is divided into multiple independent battery sources (first battery and second battery), each capable of independently powering the vehicle. This segmentation allows the system to maintain operation even when one battery fails, thereby improving reliability without requiring a completely redundant complex system.
Solution Approach 2:
The control system continuously monitors the state of charge and health of both batteries in advance. When the first battery's charge drops below a threshold or a fault is detected, the system proactively switches to the second battery before complete failure occurs, ensuring uninterrupted operation and enhancing system reliability.
2Reliability
If manual battery switching is implemented, then the system can provide backup power, but the switchover process causes disruptions and potential electrical surges
Solution Approach 1:
The control system continuously monitors the state of charge, voltage, and health status of both batteries in real-time. Based on this feedback, the controller automatically determines when switching is necessary and executes the switchover seamlessly, eliminating the need for manual intervention and preventing disruptions or electrical surges during the transition.
Solution Approach 2:
The manual mechanical battery switching operation is replaced with an automated electronic control system that manages the switchover process. This substitution eliminates human error, prevents electrical surges, and ensures smooth transitions between batteries, thereby maintaining power supply continuity.
3Reliability
If battery switchover is implemented without proper control, then backup power is available, but voltage spikes and electrical surges can damage the system
Solution Approach 1:
The control system is designed to detect battery state changes and initiate the switchover process before critical failures occur. By monitoring voltage levels and battery health in advance, the system prepares for the transition and executes it smoothly, cushioning against potential voltage spikes and electrical surges that could damage connected components.
Solution Approach 2:
The control controller acts as an intermediary between the two battery sources and the vehicle's electrical system. It manages the switchover process by controlling the connection and disconnection of batteries, ensuring that transitions occur without causing voltage spikes or electrical surges that could harm the system.
4Ease of operation
If a universal swappable battery system is implemented, then battery swapping is simplified, but the system requires multiple batteries and increased management complexity
Solution Approach 1:
The system uses universal swappable batteries with standardized connectors and interfaces that can be used across different vehicle types. This universality simplifies the battery swapping operation for users, as they can exchange batteries without needing to understand the internal complexity or match specific battery configurations to specific vehicles.
Solution Approach 2:
The control system automatically manages the multiple batteries, monitoring their state of charge, health, and compatibility with the vehicle. This self-service capability eliminates the need for users to manually manage the complexity of multiple batteries, allowing them to simply swap batteries while the system handles the rest.
