Solution Overview
Problem
Existing battery systems for electric vehicles lack effective coolant temperature and flow rate management, leading to potential overheating and increased risk of fire due to unpredictable coolant circulation patterns and lack of real-time temperature control.
Innovation Solution
A coolant inflow management device is introduced, comprising a rotation unit, a rotation panel control unit, and a communication module, which measures and adjusts coolant temperature and flow rate at entry and exit points of the battery system, ensuring these parameters remain within normal ranges by transmitting data to the battery management system for real-time monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If coolant circulation is managed without a separate management device, then device complexity is reduced, but temperature and flow rate control precision deteriorates
Solution Approach 1:
The patent introduces a coolant management device as an intermediary component between the coolant circulation system and the battery system. This device includes flow rate detection units, temperature detection units, and control units that act as mediators to measure and regulate coolant parameters, thereby achieving precise control without requiring complex integration into the existing cooling infrastructure.
Solution Approach 2:
The patent implements feedback control by using detection units to continuously monitor coolant flow rate and temperature, then feeding this information back to control units that adjust the coolant circulation accordingly. The control units receive detection results and modify circulation parameters to maintain optimal cooling conditions, creating a closed-loop control system that improves precision without proportionally increasing complexity.
2Device complexity
If coolant flow rate is not actively managed, then device complexity is reduced, but reliability of battery cooling deteriorates
Solution Approach 1:
The control units receive detection results from flow rate and temperature sensors, then actively adjust coolant circulation parameters to maintain reliable cooling. This feedback mechanism ensures the battery cooling system adapts to varying operational conditions, preventing overheating while avoiding the need for overly complex predictive control systems.
Solution Approach 2:
The coolant management device performs self-regulation by automatically adjusting coolant flow based on detected temperature and flow rate conditions. The system monitors its own performance and makes necessary adjustments without external intervention, ensuring reliable battery cooling while maintaining relatively simple system architecture.
3Device complexity
If coolant temperature is not monitored in real-time, then device complexity is reduced, but battery safety deteriorates
Solution Approach 1:
Temperature detection units continuously monitor coolant temperature and provide real-time feedback to control units. This enables the system to detect temperature changes promptly and adjust coolant circulation to prevent battery overheating, thereby reducing fire risk without requiring complex temperature prediction or management systems.
Solution Approach 2:
The temperature detection units and control units act as intermediary components that specifically address temperature monitoring and control. By introducing these dedicated intermediary elements, the system achieves reliable real-time temperature management and battery safety protection without requiring complete redesign of the cooling system architecture.
