Summary: The battery thermal management system is crucial for electric vehicles. This study established a battery pack consisting of 20 cylindrical lithium-ion batteries, along with a copper foam/paraffin composite phase change material and liquid cooling channels. A numerical model based on a physical model was built and validated by experimental results. The experimental and numerical tests showed that elevated Reynold numbers (Re) can increase temperature non-uniformity within the battery pack, and temperature differences decrease with further improvement of Re. Under 0.5C discharge, the maximum temperature difference (Delta Tmax) within different cells increased from 0.2 to 1.2 K as Re increased from 0 to 28, and then decreased to 0.4 K as Re increased to 112. The study also revealed the impact of current rate on battery temperature and Delta Tmax. Under different ambient temperatures, liquid cooling was found to be necessary for either warming up the battery in a cold environment or reducing the maximum temperature in a hot environment. Compared to pure phase change material (PCM) cooling, the hybrid PCM/liquid cooling resulted in an 8 K temperature increase and a 13 K temperature decrease at the end of discharge under a low initial temperature of 288 K and a high initial temperature of 318 K.

Summary: This study proposes a multifunctional flexible composite phase change material (CPCM) with high anti-leakage and thermal conductivity performances. The leakage problem of CPCM is addressed by polymerizing and crosslinking reaction with polyethylene glycol and hexamethylene diisocyanate.

The multifunctional flexible CPCM controls the maximum temperature of the battery module below 45 degrees C even at 1.5C discharge rate, with a temperature difference maintained within 4.3 degrees C. This multifunctional flexible CPCM provides an efficient solution to improve the thermal safety of battery packs in applications, promoting the development of electric vehicles.
