Seasonally-Adaptive Battery Thermal Management System for Electric Vehicles

Invention Description
Electric vehicles are becoming more common, especially with the push for greater utilization of renewable energy. However, it is widely known that electric vehicles suffer from safety issues associated with mistreatment, collisions, and charging issues. Further, batteries in electric vehicles often have performance degradation due to seasonal temperature fluctuation as well as inefficient thermal management which limits battery lifespan and capacity.
 
Prof. Arunachala Kannan at Arizona State University and collaborators have developed a seasonally-adaptive battery thermal management system (BTMS) designed for electric vehicles, which combines liquid cooling with two distinct phase change materials (PCMs) tailored for different ambient temperatures. It features innovative enclosure designs and serpentine liquid channels to enhance thermal efficiency, reduce volume, and improve battery performance during fast charge/discharge cycles. The system passively manages battery temperature under normal conditions using PCMs, while activating liquid cooling for extreme thermal loads, ensuring optimal thermo-electrochemical performance year-round.
 
This advanced BTMS integrates dual phase change materials and liquid cooling to optimize fast charging and discharging performance across seasonal temperature variations.
