Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If coolant is circulated through the complete coolant circuit to heat up batteries, then the batteries reach the required temperature, but excessive energy is wasted heating the entire vehicle
Solution Approach 1:
The coolant circuit is segmented into a main coolant circuit and a separate battery coolant loop. The battery coolant loop can be isolated from the main circuit using a bypass line, allowing independent thermal management of batteries without affecting the entire vehicle's coolant system.
Solution Approach 2:
The system provides localized thermal management by directing coolant flow specifically to battery exchangers when needed, rather than circulating coolant through the entire vehicle system. This localized approach heats only the batteries when required, avoiding unnecessary energy consumption.
2Temperature
If coolant is circulated through the complete coolant circuit, then all components are cooled, but much more coolant than required flows causing inefficiency
Solution Approach 1:
The coolant system is divided into separate circuits - a main coolant circuit for general vehicle cooling and a battery coolant loop for specific battery thermal management. This segmentation allows coolant to be directed only where needed, improving overall system efficiency.
Solution Approach 2:
The system dynamically adjusts coolant flow paths based on thermal requirements. The bypass line enables the battery exchangers to be connected or isolated from the main coolant circuit as needed, allowing the system to adapt coolant distribution to actual thermal demands.
3Loss of energy
If the battery exchangers are isolated from the coolant circuit, then energy waste is minimized, but the batteries cannot be cooled when needed
Solution Approach 1:
The bypass line provides dynamic connectivity, allowing the battery exchangers to be connected to or isolated from the main coolant circuit based on real-time thermal requirements. This dynamic configuration enables the system to switch between cooling and energy-saving modes as needed.
Solution Approach 2:
The bypass line acts as an intermediary element that controls the connection between the battery coolant loop and the main coolant circuit. This intermediary allows flexible thermal management by enabling or disabling coolant flow to batteries depending on operational conditions.
