Vehicle Thermal Management Using Navigation-Aware Battery Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle thermal management techniques are inefficient as they do not consider the actual application scenario of the user, leading to excessive energy consumption and waste.
Innovation Solution
A method and apparatus for vehicle thermal management that determines whether the vehicle traveling mode complies with the thermal management mode based on navigation data and traveling state, and adjusts thermal management accordingly by combining ambient temperature, upper and lower temperature limits, and estimated remaining traveling distance and time.

Engineering Contradiction Analysis
1Temperature
If fixed target temperature cooling is applied to battery regardless of application scenario, then battery temperature is controlled within specified range, but energy is wasted when user arrives at destination during or after cooling
Solution Approach 1:
The patent applies dynamics by making the thermal management system adaptive rather than static. The control unit dynamically adjusts thermal management strategies based on real-time parameters including remaining traveling distance, remaining traveling time, and ambient temperature. This allows the system to optimize cooling operations according to actual usage scenarios, preventing unnecessary energy consumption while maintaining battery temperature within safe ranges.
Solution Approach 2:
The patent implements preliminary action by estimating remaining traveling distance and time before executing thermal management operations. The control unit proactively determines whether cooling is necessary based on predicted usage patterns, allowing the system to prepare and execute thermal management only when truly needed, rather than applying fixed cooling schedules that may complete after the user has arrived at their destination.
2Device complexity
If thermal management is applied without considering application scenario, then thermal control is simplified, but energy consumption increases due to unnecessary cooling operations
Solution Approach 1:
The patent applies universality by creating a multi-functional control unit that integrates multiple functions: estimating remaining traveling distance, estimating remaining traveling time, determining thermal management requirements, and controlling thermal management components. This unified approach allows the system to handle various thermal management scenarios (cooling, heating, maintenance) through a single intelligent controller that adapts to different application contexts, preventing unnecessary energy consumption while maintaining manageable system complexity.
