Smart Adaptronic Thermal Management System Designs for The Li-ion Battery Packs

Li-ion battery packs are used in varied industrial fields, such as automotive, drone, and e-bike industries. Low temperature insulation and high temperature heat conduction are required for an ideal thermal management of battery pack. In this study, an autonomous system design is developed for a smart adaptronic Battery Thermal Management System (BTMS). We proposed two different nickel-titanium (NiTi) shape memory alloy (SMA)-actuated smart adaptronic BTMSs. The actuation strain of the system is examined using a computational NiTi shape memory alloy model for material selection. The model results showed that an actuation strain of 3.8 % can be obtained for the operating temperatures range between 15°C and 80 °C. The model results is used to unveil the required properties of NiTi SMA wire. The proposed adaptronic BTMS design solutions can create competitive advantages with their compact, low-cost, and lightweight structures in industry.
