Summary: The thermal performance of lithium-ion batteries in a battery module is significantly affected by the operating temperature, with temperatures above 40 degrees C accelerating battery aging and shortening lifespan. Among various cooling strategies, micro heat pipe arrays (MHPAs) have received little attention. Experimental results show that the angle of inclination of the MHPA has a significant impact on the temperature control, with the best thermal performance observed at an angle of -15 degrees.

Summary: The electric vehicle industry is becoming increasingly important, making the study of battery thermal management systems crucial. Heat pipe based systems have high heat transfer performance but lack uniform temperature distribution. Combining heat pipe and phase change material systems can effectively utilize their advantages and compensate for their disadvantages. This paper focuses on the less studied coupled heat pipe and phase change material systems, classifies and compares them based on heat pipe types and different methods of phase change material heat transfer enhancement, and analyzes their advantages and disadvantages. The future direction of battery thermal management systems is seen as utilizing multiple methods in conjunction with each other to ensure continuous battery operation. This review also helps update the sparse reference literature.

Summary: The study investigates a lithium-ion battery heat management system using a heat pipe, and experimentally explores its performance. The experimental results show that while increasing ambient temperature leads to a rise in battery surface temperature, the decrease in thermal resistance of the heat pipe moderates this effect and controls the battery surface temperature with forced convection, distributing temperature uniformly. The use of the heat pipe helps maintain more stable temperature conditions with lower fluctuations in consecutive battery cycles.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.
