Battery Thermal Management Control for Multi-Zone Heat Exchange
Solution Overview
Problem
Existing heat management systems for vehicles lack diversification in heat management functions, leading to inefficient heat exchange for battery modules, high energy loss, and low operating efficiency.
Innovation Solution
A control method that allows for heat exchange with a battery at different efficiencies or in different heat management modes by controlling at least one of the first and second trunks in the heat management system, which are configured to exchange heat with different areas of the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single heat management mode is used for the battery, then the system structure is simple, but the heat exchange efficiency cannot meet different battery temperature requirements
Solution Approach 1:
The heat management system is segmented into multiple independent heat management modes (first heat management mode, second heat management mode, third heat management mode) that can be selectively activated. Each mode corresponds to different battery temperature ranges and uses different heat exchange strategies, allowing the system to optimize heat exchange efficiency for specific thermal conditions without requiring a completely complex restructured system.
Solution Approach 2:
The heat management system dynamically switches between different heat management modes based on real-time battery temperature conditions. The control unit selects appropriate modes according to temperature thresholds, enabling the system to adapt its heat exchange characteristics dynamically rather than using a fixed single mode, thereby improving overall heat exchange efficiency across varying operational conditions.
2Reliability
If traditional heat management modes are used, then the system is easy to operate, but the temperature uniformity and battery performance are insufficient
Solution Approach 1:
The heat management system incorporates feedback mechanisms where the control unit continuously monitors battery temperature conditions and automatically selects appropriate heat management modes. This closed-loop control ensures optimal battery performance by responding to actual thermal states, while the automation of mode selection maintains ease of operation without requiring manual intervention or complex user decisions.
Solution Approach 2:
The system changes operational parameters by switching between different heat management modes, each with distinct heat exchange characteristics. By adjusting which mode is active based on temperature parameters, the system optimizes battery performance through parameter variation while maintaining simple operation through automated parameter selection rather than manual adjustment.
